Germany’s hydrogen truck and refueling-station subsidy call was oversubscribed. On its face, that sounds like the hydrogen freight market finally showing up. The German transport ministry’s implementation agency reported 526 applications by the deadline, requesting €455 million against €220 million available, with 71 applications for refueling stations and 455 for vehicles or fleets. That is a strong response in the narrow sense that companies will apply when the state offers enough money. It is not proof that hydrogen trucks have become competitive freight assets.

The more useful interpretation is simpler and less flattering. Germany is still trying to make hydrogen road transport happen. The country is doing it at the same time that the freight evidence is increasingly pointing in the other direction: battery-electric trucks, depot charging, corridor charging, battery swapping where routes justify it, grid planning, service ecosystems, insurance, finance and data platforms. Hydrogen road freight is still being treated as a strategic option to preserve. Electric freight is becoming an operating system to build.

The denominator matters. What was oversubscribed was not an unsubsidized market for hydrogen freight. It was a subsidy programme. Germany is offering public support for hydrogen refueling stations and N2/N3 commercial vehicles in a combined package, with up to 50% of eligible hydrogen station expenses and up to 80% of eligible additional vehicle cost compared with a diesel truck. The policy design is explicit: build stations and vehicles together so each gives the other a reason to exist.

That framing addresses the chicken-and-egg problem by funding both sides of it. The policy problem is not that Germany is spending money on clean freight. It is that the programme buys down the hydrogen supply chain’s capital problem while leaving fleet operators exposed to hydrogen’s operating-cost problem. Capex support helps with the entrance fee. Freight economics are paid by the kilometre.

The asymmetry should make fleet operators pause. Germany is not just supporting hydrogen refueling infrastructure. It is also offering purchase support for hydrogen trucks by buying down a large share of their diesel-cost premium. Battery-electric trucks, by contrast, do not appear to have a comparable current federal vehicle-purchase subsidy. Germany previously cut its broader climate-friendly commercial-vehicle purchase funding, while the electric truck support now visible at federal scale is mainly through heavy-duty charging infrastructure and motorway charging corridors. That means the policy can make hydrogen look better at the moment of procurement, even if battery-electric trucks remain stronger on lifetime cost.

That would be questionable even in isolation. It looks worse against the live freight comparator. China is not merely subsidizing electric trucks as vehicles. It is building an electric freight system around corridors, depots, charging, swapping, grid planning, standards, service networks and defined freight use cases. In my earlier article on how China is tying electric trucks to corridors, depots, service areas, charging, swapping, grids, batteries, standards and freight operations, the point was not the 40% new-energy heavy-truck sales target alone. The point was that China is not asking electric trucks to succeed one fleet at a time, unsupported by the rest of the system.

This also cuts against the serious institutional direction of travel. In my earlier article on how France and Germany’s economic councils endorsed electric trucks over hydrogen, the point was not that hydrogen trucks can never move freight. It was that the comparator had changed. Battery-electric trucks are no longer a distant possibility in heavy road freight. They are the pathway with the shorter energy chain, lower energy cost, improving vehicle availability and more obvious fit with the power system.

Germany’s hydrogen subsidy looks weaker in that light. It is spending public capital to preserve a parallel fuel system while the strategic layer of freight electrification is moving toward batteries, grids, charging, swapping, data and finance. A subsidized hydrogen corridor can create activity. It does not create the freight-energy platform that fleets will use if electric trucks become cheaper, easier to dispatch, easier to finance and easier to integrate into logistics operations.

Hydrogen truck advocates point to range, refueling speed and corridor use cases. Those are real operational attributes. They do not erase the delivered-energy chain. Hydrogen has to buy, convert, compress, distribute and dispense energy that a battery-electric truck can use more directly. A hydrogen truck can be subsidized into service, and a hydrogen station can be subsidized into existence, but the operator still has to run the route, pay the fuel bill, manage station access and carry the residual-value risk.

Below the paywall is the professional layer: the capex comparison across diesel, battery-electric and hydrogen trucks; the subsidy arithmetic that can make hydrogen look cheaper at procurement; the per-100-km energy-cost comparison where the advantage reverses; the station-utilization denominator; the China and CATL/Octopus comparator; and the update triggers I’ll use to judge whether Germany’s hydrogen freight corridor is scaling or merely preserving a road-transport hydrogen narrative with public money.

A while ago, I published a sexy-practical quadrant chart for maritime shipping decarbonization. Sharp-eyed readers noted an omission from it: nuclear power for commercial ships. While I make no claims to be encyclopedic, I do try to be relatively thorough, and it honestly did not occur to me to include it.

Imagine my surprise, then, when Giulio Gennaro, CTO of Core Power Energy, was on a panel with me at Stena Sphere’s technical summit in Glasgow. Core Power’s pitch is nuclear propulsion for commercial shipping, using small molten-salt reactors.

The panel of four included me with my projections of maritime shipping megatonnes by mode and category. Bulk shipping will decline sharply as demand for the oil, gas and coal that make up a large share of it falls. The raw iron ore portion of bulk shipping will also drop as more steel is produced from scrap and more primary processing happens closer to mines using renewable electricity and, in some cases, green hydrogen. Container shipping will rise, but not enough to offset the decline in bulk. Global population growth will slow and likely stop between 2050 and 2070 as well, reducing one of the background assumptions often used to inflate long-range shipping demand.

My view, laid out in my maintained Briefing work on shipping’s fuel transition, is that inland shipping and a large share of short-sea shipping shift to batteries. Hybrid solutions extend the transition as battery replacements increase pure-electric range and reduce fuel consumption. Scarce liquid biofuels and other residual fuels serve the smaller pool of long-distance shipping that still needs energy-dense molecules.

But this article is about the case Gennaro made for nuclear.

He was right that the biggest ships on the longest routes produce a large share of shipping emissions. That is an obvious point, but still worth stating. My solution is not to put enormous batteries on ultra-large crude carriers. Residual liquid fuels are fit for purpose in some of those segments, but it is reasonable to ask what else might work for the largest problem areas.

Core Power’s argument, as I understood it, is that only the biggest ships, traveling the longest routes, with well-known endpoints and guaranteed requirements for long ocean crossings, would make sense for nuclear propulsion. That narrows the addressable market quickly.

Those characteristics mostly describe the biggest bulk carriers for oil, coal and iron ore. Those are also the segments facing structural decline. Coal demand peaked years ago. Oil demand is approaching a peak. Iron ore flows are exposed to scrap growth, alternative steel routes, rising bulk shipping costs and more local processing near mines. Building a few very large nuclear-powered ships for a radically declining market does not slip smoothly through the waters of economic decision-making.

As one indicator of that niche going away, there were over 900 ultra-large crude carriers in service when I wrote the original CleanTechnica article, but only one of that class on order earlier that year. That was not a typo. Smaller carriers were still being ordered, but the very large ships most suitable for nuclear were not. Everyone in the market could see the stranded-asset risk.

Core Power’s preferred technology is small molten-salt nuclear reactors. That adds another layer of risk. Molten-salt reactor ideas have been around since the 1960s, but they have not become commercial products at scale. There were tiny prototype MSRs in China when I last checked, but a prototype is not a bankable marine product. A nuclear commercial shipping pathway based on a reactor class that has not been deployed commercially is a first-of-a-kind risk stack inside an already conservative, capital-intensive industry.

Claims that it will be safer or cheaper do not stand up to much scrutiny when the product has not been deployed in earnest. The safety claim is especially interesting because the sales pitch includes proactively dealing with port, government, shipping-industry and civilian concerns about nuclear safety. In my opinion, nuclear reactors are generally very safe, and radiation from reactor accidents, even Chernobyl and Fukushima, is not remotely comparable as a global risk to climate change.

It is not fear of radiation that makes me question nuclear energy in commercial shipping.

The problem is that my informed opinion is not shared by every government, port authority, insurer, regulator, cargo owner or member of the public. The last time commercial nuclear-powered freight was tried was in the 1950s and 1960s. New Zealand passed a law banning nuclear ships in its ports, and it remains on the books. Turkey and Spain said no. The UK demanded extra liability insurance. Commercial nuclear-powered ships disappeared as a commercial category.

Since then, Chernobyl and Fukushima have occurred. Nuclear safety concerns still exist, although they have changed form. Governments are much more aware of exclusion zones, emergency planning and long-tailed economic liability. There is more interest in new nuclear again in some countries, especially as Europe works to escape the consequences of Russian gas dependency, but that does not translate cleanly into enthusiasm for nuclear ships entering commercial ports.

Among other things, security and regulatory requirements for ports go up. That is not a side detail. Commercial shipping is a port-dependent system. If a ship requires exceptional handling, exceptional liability arrangements, exceptional security treatment, exceptional inspection regimes or exclusion from some ports, the ship becomes less commercially liquid. The reactor may fit the hull, but the business has to fit ports, insurers, customers, charters and regulators as well.

Having published extensively on small modular reactor economics and why manufacturing learning curves do not rescue SMRs, I know that any marine SMR system would likely cost several times the value of the basic ship. A $100 million bulk carrier could become a $400 million vessel once the reactor system and associated requirements are included. Only ship owner-operators would find the use case even potentially viable, because ship owners who lease vessels would carry the capital cost without necessarily receiving all operational benefits.

A novel business model would be required. That is another limitation on the market, because many ships are owned by one party and leased, chartered or operated by another. Maritime markets rely on tradable assets, financeable hulls, insurance norms, resale pathways and standardized commercial treatment. Nuclear propulsion interrupts that machinery.

Gennaro was asked about regulatory compliance for commercial nuclear and argued that shipbuilders and owners would be isolated from it because Core Power would build, install and lease the reactors, while owning liability, maintenance and decommissioning. He compared it to engine manufacturers providing warranties and maintenance for engines.

That analogy is weak. A leased reactor is not a marine engine warranty with a different fuel. It does not remove regulatory, liability and operational burden from ports, ship owners, ship leasers, cargo owners and insurers. The exceptional technology still enters the commercial system.

It is like an industrial plant powered by a dedicated coal plant across the fence and operated by a third party claiming that the coal plant’s emissions should not be counted in the industrial process. I heard that example from Laurent Segalen, who spotted it while running Scope 1, 2 and 3 deployment examples, a framework he was integral to developing. Moving an obligation outside the fence does not make it disappear.

Then there is the lifetime mismatch. SMRs are usually discussed as long-lived assets. Nuclear reactors are often forty-year solutions. Big commercial hulls typically have target lifetimes closer to twenty-five or thirty years. One can imagine pulling a reactor out of a decommissioned ship and putting it into another hull, but pulling a major marine power plant is already non-trivial before nuclear security, regulation, inspection and recertification are added. The timeframes do not line up cleanly.

The fuel expectation adds another problem. Most SMR designs expect high-assay, low-enriched uranium, or HALEU. That should make the fuel topic ordinary, but it does not. Russia has historically dominated HALEU processing. The United States and others are trying to create non-Russian HALEU supply chains, but establishing that kind of fuel chain is not trivial. A commercial shipping pathway dependent on a constrained nuclear fuel supply adds geopolitical and supply-chain risk to a market that already has simpler alternatives.

Nuclear works in military ships and extreme-condition icebreakers, which are effectively state missions. In those cases, refueling difficulty, strategic mobility, endurance and mission assurance justify extraordinary cost and institutional burden. Commercial shipping is a different reference class. It is cost-sensitive, port-dependent, leased, financed, insured and exposed to cargo shifts.

Core Power’s pitch faces a declining addressable market, a non-commercial reactor product, higher port and regulatory burden, a likely high capital-cost premium, an awkward ownership model, a lifetime mismatch and a fuel supply chain exposed to geopolitical risk.

The question of nuclear for commercial ships is so flawed from a business perspective that I did not include it in my original sexy-versus-impractical maritime decarbonization chart. Perhaps that was an oversight. Core Power managed to raise enough money to keep pitching the idea and put executives on stages, but that is not the same thing as delivering a working, financeable, insurable, port-accepted nuclear propulsion system for commercial shipping.

The maintained Briefing view is simple. Nuclear propulsion can move ships. It has already done so. But commercial shipping does not buy propulsion systems in isolation. It buys vessels that can move through ports, contracts, insurers, fuel chains, owners, operators, charterers and asset markets. Nuclear commercial shipping still does not fit that system.

This article is archived and lightly updated from an earlier CleanTechnica analysis.

Prague has put useful numbers behind an argument transit agencies should already have been testing: hard bus routes do not automatically require new fuels. They require the right electric architecture.

The first operating-cost data from DPP, Prague’s public transport company, are early and route-specific, but they are much more useful than another brochure comparison between vehicle types. Zdopravy reported that DPP compared electric buses and partial trolleybuses against diesel buses while including vehicle depreciation, infrastructure construction, infrastructure maintenance, and related costs. On line 58, DPP’s transport director Jan Barchánek said the full per-kilometer cost came in only about 10% above comparable diesel operation without subsidies, and slightly below diesel once grants for vehicles and infrastructure were counted.

That is not a universal verdict for every city, route, or procurement. It is more interesting than that. It shows that a direct-electric bus system can get close to diesel economics on selected difficult routes when the design question is asked properly. Not “can a battery bus replace a diesel bus one for one?” Not “can a trolleybus return as a nostalgic historical mode?” The better question is what mix of batteries, wires, chargers, substations, route geometry, layover windows, passenger load, and annual kilometers actually delivers the service.

That is the context for modern in-motion charging trolleybuses. Earlier this year, I wrote that the current trolleybus revival is not about reviving a fixed-wire relic. Modern IMC trolleybuses are battery-equipped electric buses that charge while moving under wires and run off-wire where continuous wiring is unnecessary, visually sensitive, operationally awkward, or simply not worth the cost. Prague was already a useful case in that assessment because line 59 to the airport combined steep grades, heavy passenger loads, high frequency, and large double-articulated vehicles.

The new data are focused on line 58, not the airport line, which strengthens the point. The airport corridor was always an obvious high-capacity candidate. Line 58 makes the strategy look less like a showcase and more like network planning. Magyarbusz’s useful framing is that Prague is not just restarting trolleybus service, but building a deliberate electrification strategy for hilly, high-load bus corridors where diesel consumption is high and battery-only operation can become operationally constrained.

The most important technical detail is not the wire. It is the battery burden. DPP says that in a partial trolleybus, only about 40% of the vehicle’s energy flows through the battery, while in a pure battery-electric bus effectively 100% does. That is a lifecycle-cost statement hiding inside an energy-flow statement. Batteries are not just purchased once in a procurement spreadsheet. They are cycled, heated, cooled, replaced, oversized, constrained by charging windows, and judged by whether they let the vehicle do enough useful work every year.

Selective wire changes that equation. Put direct power on the hilly or high-load segments, let the vehicle charge while doing revenue service, and use the battery where flexibility is valuable. The battery becomes part of the system rather than the whole system. That is the missing middle between depot-only battery buses and old-style continuous-wire trolleybuses.

Prague’s battery-bus results point in the same direction rather than the opposite one. DPP says its older Škoda electric buses with Temsa bodies come in at about 104 to 105% of diesel costs before subsidies, and slightly below diesel after subsidies, on the right services. The explanation is not that batteries have escaped operational constraints. It is that Prague can connect electric buses to an existing electric transit ecosystem: tram infrastructure, substations, regenerative braking energy, and terminal charging.

Utilization is the denominator that keeps getting lost. DPP says the average diesel bus in Prague runs about 50,000 kilometers per year, while its electric buses reached 67,000 kilometers last year. Barchánek said the economics start to work around 65,000 to 70,000 kilometers per year, which is harder for buses that only charge overnight in garages. Capital cost looks different when the vehicle can do more annual service. So does battery sizing, charger count, depot space, maintenance planning, and spare ratio.

This is where the hydrogen bus procurement argument becomes much weaker. Hydrogen is usually pulled into the bus conversation through edge cases: hills, cold weather, long duties, limited depot charging, high passenger loads, and the desire to keep vehicles in service. Prague is showing that those are not necessarily hydrogen requirements. They are route-design and charging-architecture requirements.

That distinction matters. A hydrogen bus is not just a bus with a different tank. It brings a fuel chain: electricity or gas into hydrogen production, compression or liquefaction, storage, distribution or on-site production, refueling equipment, safety systems, specialized maintenance, and fuel-price exposure. A direct-electric transit system brings wires, chargers, substations, batteries, vehicles, and power-system integration. Both require infrastructure. Only one keeps inventing a fuel to avoid using electricity directly.

Subsidies still need honest treatment. Prague’s line 58 result is slightly below diesel on DPP’s books after grants, but subsidies do not make physical costs vanish. They change who pays. The more defensible policy argument is that grants for trolley wires, substations, chargers, and electric buses buy durable public infrastructure for a direct-electric transit system. Grants for hydrogen buses too often buy participation in a fragile fuel ecosystem that still has to prove delivered fuel cost, station reliability, vehicle availability, and repeat procurement after pilot funding fades.

The Prague lesson is not that trolleybuses beat battery buses. It is that electric transit architecture beats fuel substitution. Battery buses work where routes, chargers, layovers, and annual kilometers fit. Opportunity-charged buses work where existing electrical infrastructure can be used intelligently. IMC trolleybuses work where hills, passenger loads, and utilization make battery-only operation less attractive. The categories overlap, and a serious transit agency should be sorting routes into them rather than treating one vehicle type as the universal answer.

That leaves hydrogen with the burden it should have had all along. It has to beat the actual direct-electric alternatives, not a caricature of them. It has to beat depot-charged buses on routes where depot charging works. It has to beat opportunity-charged buses where terminals and substations fit. It has to beat IMC trolleybuses where selective wire reduces battery size, battery cycling, and charging downtime.

Many routes described as too hard for batteries are not hydrogen routes. They are routes where the battery should not be left alone. Prague is now putting early cost evidence behind that distinction, and it is a distinction transit agencies, policymakers, and investors should take seriously before funding another molecule-shaped detour around electricity.

Data on the current costs of small modular nuclear reactors (SMR) is starting to roll in. As a result, it’s now possible to make some projections of how long it would take for their costs to drop to the level of renewables today. The results aren’t good for SMRs.

Who are our contestants? NuScale and Last Energy have signed contracts, definite in the case of the former and of unknown quality in the case of the latter. As a result, we know their current costs, long before they actually deliver any electricity anywhere. I’m going to give them massive benefits of the doubt that their costs won’t multiply further, a very conservative concession given that they are both first of a kind technologies which have no working, deployed units yet.

Both are American firms. Per crunchbase, one of my go-to sources for funding insights, NuScale has raised about $470 million and is based in Oregon. Per LinkedIn, they have about 570 employees and are in the oil and gas sector. I assume the first is mostly accurate, but that the second isn’t. Last Energy is based in Washington, DC, has raised $3 million, and has about 40 employees.

What are they claiming in terms of contracts and deliveries? Well, NuScale is way behind schedule and over budget on delivering six 77 MW units to an Idaho National Laboratory site. Even with direct government funding of $1.4 billion from the US DOE and a $30 per MWh tax break from the Inflation Reduction Act, it’s still coming in at $89 per MWh wholesale cost of electricity. Unsubsidized, lets generously call it $120 per MWh, approaching the average retail price of electricity in the US.

As for Last Energy, with its $3 million in funding, Beltway location, and <50 employees, it recently announced deals in Poland and the UK for 34 reactors, each 20 MW in capacity, for an eye watering $19 billion. That works out to about $161 per MWh wholesale at best, above the retail price of electricity in those countries, and remarkably even above the cost per MWh of the far behind schedule and far over budget Hinkley Point C project. Let’s pretend that a firm with $3 million in funding and <50 employees have signed deals worth $19 billion and we should believe these deals are remotely firm. We are, after all, giving SMRs every benefit of the doubt in order to see what might happen.

The premise of small modular reactors is that the observed reality of economies of scale due to mass manufacturing will kick in. It was first observed in the 1930s by an efficiency expert, and is often referred to as Wright’s Law after him. The Boston Consulting Group stole the idea, called it the experience curve and sold it to their clients along with a strong recommendation to create monopolies with it. Sometimes it’s called the learning curve.

At heart, all it says is that manufacturing experience is an s-curve of cheaper costs per unit. Costs stay level for a bit at the beginning, then drop by 20% to 27% with every doubling of numbers, and then after a bunch of doublings flatten out again. Stuff like screws, nuts, and toaster elements are as cheap as they are going to get because we’ve made millions of them and they are in flat part of the curve at the end. Things like small modular reactors are still in the flat part of the curve at the beginning.

I put a question to Professor Bent Flyvbjerg, a global expert on modularity and megaprojects, a year or so ago about SMRs and Wright’s Law. He’d asked if he could include some of my material on the natural experiment of wind and solar vs nuclear in China in his book, How Big Things Get Done, which was published a month or so ago. That gave me the opportunity to ask his deeply informed opinion on the subject. The question I asked was about the number of units in the initial flat part of the s-curve. He said dozens. I took that to mean perhaps 60 or 70 units before the doubling cost reduction really kicked in. Someone commented on a post of mine on LinkedIn that Rolls Royce expected it would have to manufacture and sell 50 of its proposed units before prices fell, but I haven’t validated that statement, and as its SMRs are 470 MW capacity that’s about 24 GW of sales regardless.

So I had a starting point for two SMR technologies, a doubling ratio, and could create a couple of scenarios, one for each. Doubling would have different effects, since NuScale was starting at a lower cost point per MWh — and remember I’m giving both of them the huge benefit of the doubt that either will come in at current costs — but had units about 4 times the capacity, so doubling of volume would be slower. Last Energy purports to have tiny units and is asserting that it has deals for a lot more of them numerically, but is starting at a much higher cost point. Once again, to give SMRs every benefit of the doubt, I’m going to pick a high learning curve value of 25%, not halfway between 20% and 27%.

I decided to go with an aggressive sales profile for both companies through 2040, with both experiencing massive successes in selling more of their very expensive, unproven, first of a kind products. Like assuming that their current costs wouldn’t rise radically, this was once again a very conservative option that was very much in their favor in terms of the analysis.

Selling lots more units every couple of years through 2040 would lead to these companies which have delivered nothing so far having sold about 500 units with a capacity around 40 GW for NuScale and about 2,500 units with a capacity of around 50 GW for Last Energy.

For context, there are only about 440 operating commercial nuclear reactors in the world with a combined capacity of about 400 GW, so these numbers would represent a massive increase in the number of reactors and 10% and 13% of global nuclear generation capacity increases in 17 years. Once again, this is an absurdly optimistic forecast for this technology, and is incredibly favorable to their price decreases.

And what are the results?

Well, with massive increases in numbers in both cases and with the assumption that they’ll hit current cost projections, neither gets close to the current global averages for wind or solar. Neither gets below $50 per MWh in 2023 dollars. Coincidentally, both get to $51 per MWh, which wasn’t something I gamed, just something that fell out the bottom of my really aggressive success scenarios for both of them.

When I did the analysis of the SMR space initially, I found that there were about 18 designs extant at the time. They are all competing with one another. They have different governmental backers. As I pointed out in discussions of the space, the only chance any has of becoming a cheap form of generation is if a major geographical region like the US or EU picks a winning design, forces it down everyone’s throats, and as a result maybe reaps the benefits of Wright’s Law.

But these two scenarios would already add 23% to global nuclear capacity when it’s been pretty flat for a couple of decades. And nine times as many firms would double current nuclear capacity. That’s really unlikely when all of this SMR electricity would be so expensive and wind, solar, transmission, and storage are so cheap.

What’s more likely to happen is pretty obvious. The odds that Last Energy delivers anything approaches zero, and its deals are mostly likely of the same quality as a lot of SPAC MOUs and LOIs that have riddled the space. It wouldn’t surprise me if they are looking for a SPAC reverse takeover right now. As a result, the company getting to 2,500 delivered units and achieving not terribly expensive energy in 2040 (when we need lots of it by 2030) is something I would find extraordinarily surprising.

As for NuScale, municipal partners in the deal keep leaving it, costs keep rising, the first connection to the grid has been pushed back to 2029 with the current unrealistic schedule, and it has MOUs and design contracts in a few places around the world with the faint hope that it will deliver something somewhere before 2030. Most of its target customers in the US and elsewhere don’t have nuclear generation in their portfolios today and most of the countries aren’t integrated into the IAEA for commercial generation. The seven overlapping rings of security requirements for commercial nuclear generation I describe in my assessment space for SMRs have only started to be put in place, and they are non-trivial. The odds that NuScale realizes deployment of even 50 of its reactors are low, so the odds that it will get the first increment of value from Wright’s Law approaches zero. They’ll remain expensive, if indeed they ever get grid connections anywhere.

Wright’s Law isn’t going to save the deep inefficiencies of SMRs. As I pointed out previously, the world tried tiny commercial nuclear reactors in the 1960s and 1970s, they were too expensive due to the physics of thermal generation, and SMRs wouldn’t be successful in overcoming that with massive numbers of units.

This article is archived and lightly updated from an earlier CleanTechnica analysis.

A few years ago, a STEM and economics literate global decarbonization executive for a $4 billion annual revenue logistics business operating in most of the major trading companies of the world asked me “What drives this madness on hydrogen?” They were being peppered with irrational proposals for the molecule and its derivatives. I answered at length with the motivations that were creating cognitive biases among the self-supporting circle of fossil fuel firms, their financial firms, the countries with high oil rents and firms whose only intellectual capital is in technology which burns fossil fuels like internal combustion engine manufacturers.

Then I had an equivalent question from someone engaged by the Bulletin of the Atomic Scientists. The individual isn’t an industry insider and didn’t have a particular iron in the fire, but had been engaged to write a Bulletin piece on the perplexing enthusiasm small modular nuclear reactors (SMR) are seeing from an overlapping circle of advocates and firms.

This was, of course, in the week when NuScale inevitably imploded, a story I’ll return to as I unpack some of the motivations behind those thinking a bunch of lab technologies that have been around for decades that depend on uranium from Russia, that don’t have the physical characteristics for cheap nuclear generation and don’t have the conditions for success for nuclear generation will be the saviours of the nuclear industry and a key wedge in fighting climate change.

The Bulletin, as a reminder, is the non-profit organization founded in 1945 by Albert Einstein and several of the scientists involved in the US creation of the atomic weapons detonated in Japan at the end of World War 2. Its founders realized that the weapons technology had the potential to destroy the human race and decided that informing the public and policy makers about the dangers was a good idea. Their most high-profile publication is the Doomsday Clock, a metaphorical meter of how close the human race is to destroying itself. They’ve branched out to a lot of science communication on other threats like climate change, AI and COVID, but still have a core focus on nuclear energy and weapons.

Some bona fides. I like nuclear generation. I know it’s safe enough. I’m not concerned about radiation. I know it is capable of 90% capacity factors and limited load following. I’ve published assessments on nuclear vs renewables scaling in China that have garnered reasonable attention, material on the prerequisites for successful nuclear programs (and why those prerequisites don’t exist in the 21st Century), a bunch of other basic nuclear grounding pieces and a fair amount about why small modular nuclear reactors are head scratchers. I just know that it doesn’t have the conditions for success to be built and scaled economically in the 21st Century, and wind, water, solar, transmission and storage do.

The Bulletin representative undoubtedly saw something I’d written and put me on the long list of people to interview. We had that conversation this week, and it’s worth writing down the perspective I shared with them.

Keep in mind the following. Everything you read after this point about why different groups are supporting small modular nuclear reactors and nuclear energy in general is my opinion. Many of the individuals or groups would deny vociferously that the motivations and logical fallacies that I’m going to attribute to them are accurate, even as they would feel a frisson of cognitive dissonance that tells them something is not quite right. In most cases, these people and groups believe that they are correct and that their positions are rational and carefully thought through.

And so to a tangled web that includes Bill Gates, Silicon Valley, desperate coal towns, desperate nuclear towns, the inability of the USA to build big infrastructure, the US Department of Energy’s budget, magical thinking and more.

What are the seven conditions for success for nuclear energy?

There have been successful nuclear generation deployment programs in the world. The USA, France, Canada and South Korea managed it, more or less. Given the embarrassing track record of massive cost and schedule overruns that have led to nuclear generation deployments being 23rd of 25 categories in megaproject expert Bent Flyvbjerg’s 16,000+ dataset of programs sorted by likelihood to succeed, what worked in the past?

They were national strategic programs. The strategic programs were aligned with nuclear weapons programs. The government picked and enforced a single design for all of the reactors. The reactors were GW-scale due to thermal efficiencies required for cost effectiveness. The government ran human resourcing. The programs ran for 20 or 30 years. They built dozens of nuclear reactors to maintain the teams and momentum and to share lessons learned.

This is obvious stuff looking backward from 2023. As I noted recently, nuclear energy and free markets aren’t compatible. Nuclear programs are state programs with subordinate corporate partnerships.

As a note, China couldn’t recreate the conditions for success despite having every ability to so. Their nuclear program peaked in 2018 with seven reactors achieving commercial operation but has been averaging three reactors a year since. This year the single reactor that’s been connected to the grid may not achieve commercial operation. In my assessment, their industrial export strategy led them to build too many technologies and designs of reactors instead of rigorously enforcing a single design, hamstringing the deployment and scaling effort.

No country globally has the conditions for success for nuclear generation in the 21st Century. That was a Cold War era success story based on a hyperawareness of the threat of nuclear war which is vastly diminished in the age of trade.

What are small modular nuclear reactors?

The name kind of gives it away. The vast majority of the 450 or so nuclear reactors in the world that are generating electricity that gets put into the grid are gigawatt scale. That’s because attempts in the 1950s and 1960s to generate electricity with the scale of reactors on nuclear subs and aircraft carriers found that they were really expensive at that size.

But gigawatt scale reactors are easy to turn into bespoke engineering megaprojects. Custom engineering for every site foregoes economies of manufacturing scale.

So the SMR crowd decided to ignore most of history’s lessons about both the scale of reactors for commercial success and the conditions for success and lean into tiny reactors and lots of numbers. The hope was that Wright’s Law — where every doubling of the number of manufactured items once in production manufacturing would bring cost per item down by 20% to 27% — would enable them to be manufactured and deployed cheaply. However, the doubling requires an awful lot of reactors, and only under the most unrealistically optimistic of scenarios are they in the price range of wind and solar today by 2040.

The last condition for success was repeating the deployment a bunch of times, but historically that’s been dozens, not thousands. Rigorously repeating deployment of the same proven design with skilled teams in a relatively short timeframe with lots of national control and military rigour isn’t a feature of the SMR bandwagon and proposals.

No, the SMR crowd think that there’s a free market friendly version of nuclear generation. They mostly ignore the seven layers of overlapping security required for any commercial nuclear generation solution. They ignore the thermal and hence cost efficiencies of scale. They ignore the advantages of proven, simpler technologies in favour of novelty. They ignore the lack of military interest in a modern strategic nuclear program. They ignore that they don’t have a major economy and geography backing a winner and forcing it to success, no matter what it costs.

And clearly they don’t pay much attention to modern competitors like wind and solar energy.

There’s almost nothing new in the SMR technologies and designs by the way. Some of them were operational in labs in the 1950s. Most of the technologies were never commercialized anywhere despite various attempts. Their claims about being safer are pretty meaningless as passive safety features exist on lots of the operational GW scale reactors and no one is building unsafe reactors anymore.

One thing that is relatively new is that most or perhaps all of the designs require high assay low enrichment uranium (HALEU). That would be fine, except that Russia had effectively been ceded a monopoly on the supply chain for the fuel. The US DOE (again) has created a consortium model to try to create a reasonably large domestic supply of the material, well above the scale currently available domestically for laboratory reactors.

So why are people paying attention to SMRs? That’s the nub of it, and there are a lot of different answers, just as with hydrogen for energy. There’s a circle of hope, delusion and despair that is grasping at SMR straws. Let’s pull it apart.

2001 is calling

In the early 2000s, wind, solar and batteries hadn’t seen massive global deployments and astounding cost reductions, and wind and solar especially had not been proven to be able to be managed to create reliable grids. Nuclear was the clear deployable low-carbon, low-pollution alternative. It was quite possible to have an informed, logical and defensible opinion at the time that nuclear would dominate low-carbon electrical generation. Memories of the successful nuclear deployments, if not why they were successful, were top of mind in people’s heads.

Many people such as Michael Shellenberger and seemingly everyone involved with the Pritzer-funded Breakthrough Institute became convinced that lots of nuclear energy was required quickly and everything else was a distraction. There’s no obvious connection between the Institute and Breakthrough Energy Ventures, but there’s clearly an intellectual one.

Bill Gates, founder, funder and Chair of small modular reactor firm TerraPower founded the latter. He brought a set of other pro-nuclear billionaires along for the ride including Mukesh Ambani, Jeff Bezos who has money in fusion, Richard Branson who is a public advocate for nuclear, Chris Hohn whose hedge fund was invested in a Japanese nuclear utility whose assets included nuclear power stations, Vinod Khosla who blames environmentalists for nuclear’s economic failures, Jack Ma who was instrumental in Chinese involvement in the UK’s Hinkley Point C nuclear expansion and even Ratan Tata, former Chair of Tata Group who was instrumental in building nuclear energy in India.

Many of these people’s hearts are in approximately the right place regarding addressing climate change, but billionaires are surrounded by a chorus of sycophants and so find it easy to end up having their opinions reinforced rather than challenged as data changes.

And by 2015 when Breakthrough Energy Ventures was founded, data had changed. Wind and solar were already being deployed at remarkable scales without running over budget or schedule. China’s nuclear program was already struggling while its wind, solar and hydro programs were running well. It was clear to outside observers that the premise of Venture was flawed.

Shellenberger couldn’t let go of his fixation on nuclear as the solution when data changed. So instead he started attacking renewables relentlessly, falsely and illogically. When that didn’t work, and it was clear that renewables were the primary answer to decarbonizing electricity to address climate change, he became a climate change denier instead. It was impossible for him to let go of his public commitment and admit that he was wrong, and so he became even more wrong.

At that, he’s done less harm than Breakthrough Energy Ventures. It continues to fund nonsense like Heirloom and AirLoom most recently, and Heliogen in the past. Gates’ TerraPower is funded by US DOE money as much as anything else, and he goes cap in hand to Congress to demand that nuclear get more subsidies than it already does and that renewables be short changed.

The Ventures crowd are deeply influential. They have the ear of billionaires and national leaders. What they whisper major media outlets amplify. And they are simply wrong because they are stuck in the early 2000s and haven’t updated their priors with modern results.

Their support for small modular nuclear reactors as something which is going to fix nuclear energy’s modern inability to be delivered on schedule and budget in developed countries comes because they didn’t analyze why nuclear programs were successful in the past and why SMRs won’t fix that.

Silicon Valley energy ‘disruptors’

Silicon Valley has done a lot of things in its innovation history. Early on, it did tremendous work with electronics and physical computers. More recently, it has exploited the internet mercilessly to both destroy and create value chains where data of any form was moving around or persisting. Quite a lot of what the Valley has done is destroy capital, but it has created some amazing firms and attracted a lot of talent. Some of the firms are even good things for humanity and many of the people try to have their hearts in the right places. And in the Valley, if something already exists there’s a strong tendency to think it’s obsolete and that novel things are by definition better.

Facebook and Google had stormed the world of data, media and entertainment. Moving fast and breaking things worked to make a lot of tech bros absurdly wealthy. Surely there must be another market ripe for disruption. And so they turned to energy. It was electrons. It flowed through wires. Obviously it was just as easy to disrupt as data!

Silicon Valley venture capitalists loved the idea of all the money sloshing around the world of energy. They saw the potential for all of the fossil fuel money flowing into their bank accounts and their kids’ trust funds. A whole lot of nonsense technologies received a lot of funding, including a bunch of small modular nuclear reactor and fusion startups.

Yeah, not so fast. Electricity does not equal data. You can’t compress or multiplex electricity. The grid is the biggest machine in the world, not a bunch of printing presses and hard drinking writers in New York.

The biggest machine in the world is like a very large crude carrier and the icebergs of wind and solar were already directly in its path and getting bigger every year. By not actually learning about energy, electricity and the grid, a bunch of Dunning Krugered up tech bros and women wasted a lot of venture capitalist money.

The actual disruptive technologies already existed for decarbonizing energy, so the tech bros discounted them at the expense of lots of wasted cleantech capital. The recent SPAC craze which has flung lots of money at bad ideas like Energy Vault and NuScale is just more of the same.

Conservative vs liberal tribalism and mental flexibility

Due to the relationship between nuclear weapons and nuclear generation, a lot of liberal, progressive people became opposed to nuclear generation. When the military was heavily involved in nuclear generation and nuclear technologies were being used for both fuel for generation and fuel for thermonuclear weapons, that wasn’t an unreasonable position. The Bulletin was formed because nuclear weapons were clearly an existential threat to humanity.

It became a tribal conservative vs liberal thing, with conservatives favouring fossil fuels and nuclear power, and liberals favouring renewable generation.

On the liberal side, that meant that confirmation bias led them to accepting all sorts of nonsense about the dangers of radiation as fact, instead of the fiction it mostly was. On the conservative side, that meant that a deep opposition to renewables tended to spring up.

From a cognitive perspective, the studies are pretty clear. People with a liberal mindset are a bit better at changing their minds when new data comes along. People with a conservative mindset are a bit worse at that. So in the 2020s, there are a lot of people who were formerly opposed to nuclear generation who have stopped having palpitations about radiation and meltdowns, and instead are happy enough when nuclear plants get commissioned, but consider them more of a distraction.

Meanwhile, on the conservative side of things, there’s still a lot of resistance to the empirical reality of massively successful, cheap and reliable renewables. And there’s an inability to accurately diagnose why nuclear generation succeeded in the past because it conflicts with their biases. In the case of the billionaires, it interferes with their bias for the liberalized economics which have made them billionaires. It’s very difficult to find an even fiscally centrist billionaire because tax cuts for oligarchs is just accepted as their due.

SMRs fall neatly into this void, promising that their favoured tribal technology will finally take off again with this one, simple change.

Conservatives kicking climate can down the road

Regardless of degree, conservative voters and politicians in every country in the world are less interested in actually doing something meaningful about global warming than progressive and liberal voters. The Republicans in the USA along with DINOs like Manchin don’t even pretend to be interested, with the last two Republican Presidents walking away from global treaties on the subject and leaning into fossil fuels.

Small modular nuclear reactors have a lot of upsides for conservative politicians. They are all unproven, first of a kind commercial technologies so there’s a decade of design, debate, development and regulatory work before any will be up and running. That’s cheap money and keeps the fossil fuels burning longer. The promise of keeping dying or dead coal or nuclear towns alive wins votes. The promise of nuclear instead of renewables wins votes among their fans.

And they don’t have to change anything. Actually delivering climate value is deferred so long that they can ignore the file for another decade if they insert the promise of SMRs into the mix.

And to be clear, if the conservative politicians were advancing a nuclear first policy with a clear understanding of the conditions for success and working hard to create those conditions in some country, I would be quite happy for that country. It’s just that they aren’t. It’s delaying and deferring, not creating a national strategic program.

US Department of Energy thumb on the scale

A key point to remember about the US DOE is that 55% of its budget is related to commercial nuclear generation. The other 45% covers dams, geothermal, wind, solar, tidal, wave, biomass and biofuel energy.

There are two results from this. The first is that it’s much easier to get big DOE money for small modular nuclear reactors than it is for any other form of generation, although hydrogen for energy plays are giving nuclear a run for its money right now. Gates’ TerraPower and the just-failed NuScale both have received hundreds of millions of free money from the DOE in their lifespans so far. Like the continued efforts from the DOE around the perpetually failing technologies of perovskite solar panels, supercritical CO2 thermal generation and concentrating solar power, the DOE just can’t help continuing to back bad ideas.

Which gets to the next problem. The DOE is a bureaucracy with all the pros and cons of that form of organization. It has internal politics. That 55% of budget for nuclear is jealously guarded and the source of lots of authority and influence. Bureaucracies persist and add to themselves. They don’t voluntarily wind down.

And the people in that side of the DOE are watching a cliff looming toward them. Virtually every nuclear reactor operating in the USA is reaching its end of life in the next decade. What’s coming is a century of decommissioning that’s underfunded. That’s not fun. That’s not delivering lifeblood energy to a vibrant economy. That’s cleaning up the mess it left behind.

They aren’t stupid. They’ve watched the debacle of the Westinghouse AP1000 failures at Vogtle and Summer deployments. They’ve watched the European EPR program fail just as badly in Flamanville, Hinkley and Olkiluoto. They lived through the aftermath of the Fukushima disaster, which will approach a trillion USD in economic and clean up costs for Japan by the time the dust has finally settled decades from now.

They know that they can’t get support to build more GW scale nuclear reactors. No one is buying that story anymore, although few are clear on the conditions for success. So SMRs are a big area of hope for them. 55% of the DOE’s $150 billion budget pays for a lot of attention and air cover for a very low likelihood of success technology.

It pays for a lot of people to go to conferences with other like minded people where they agree with one another, usually politely but sometimes in heated ways, arguing about arcana that are irrelevant to the big problem SMRs face, that they just don’t solve the industry’s challenges.

Nuclear towns looking at the abyss

There are a lot of small towns with big nuclear plants in the world. Ontario’s Bruce nuclear facility is located in the township of Kincardine, population 12,000, as one example. Bruce Power employs 4,000 people.

There are similar examples across the USA and Europe. The nuclear facility is the big industry in town. People who work there are paid a lot compared to rural averages. It’s the major lifeblood industry. If the nuclear plant shuts down, the town withers and dies.

The town is looking at the looming cliff as reactors age out and are shut down. The county of 70,000 is looking at a huge part of its rural economy disappearing. Provincial politicians and bureaucrats are aware of the risk and don’t like it because pockets of affluence turning into pockets of poverty is a headache. Conservative politicians especially are looking to preserve those rural votes because that’s how they get elected.

So while the nuclear facility on the other side of Toronto, in Pickering with its population of 100,000 and lots of nearby employment opportunities in the manufacturing centres of Whitby and Oshawa and light rail for commuters into Toronto, is mothballed after a short extension, Bruce Nuclear gets a new SMR project that’s going to ‘save’ the facility and the town.

To be clear, if SMRs made sense, existing nuclear power generation facilities are the place to build them. They are already at the centre of the seven overlapping layers of defence that nuclear generation sites require from the international, all supply and waste chains and the physical and electronic security of the facility itself.

Unfortunately, SMRs don’t make sense, so it’s false hope for the community. But the provincial Conservatives locked in Bruce County votes for themselves by starting to explore the design and permitting of a Brookfield Westinghouse SMR technology that’s never been deployed. And they cemented their ties to Brookfield, a global powerhouse. And they threw scraps to Canadian firms SNC Lavalin — a perpetual receiver of corporate welfare which owns the CANDU nuclear assets as well as a history of corruption that’s hard to believe — and some Canadian construction firm called AECON, not to be confused with the competent global firm AECOM. I’m sure that there’s a story there too. The politics of the corporate ties are barely obscured.

Coal towns looking at the abyss

There are a lot of towns that used to have great work digging coal out of the ground near the town, processing it and putting into coal generation near the town. Delta, Utah springs to mind. It’s a town of about 3,600 people in Millard County, population 13,000. About 400 people work in the coal plant.

Coal isn’t facing a cliff, it’s falling off the cliff already in the USA.

Irrational behaviour is ensuing. The first major loan that Jigar Shah, head of the loans program office at the US DOE was able to get through and announce with much fanfare was $504 million for the Delta coal facility. The premises of the loan make absolutely no sense. The town’s electrical generation goes into transmission wires that go over the mountains to LA, 500 miles as the obsessive compulsive crow flies — seriously, did whoever created that idiom never watch any crows? — and the first premise and the only one with the tiniest bit of reality to it is that they are going to reuse that infrastructure.

Sure, but what’s required to reuse that infrastructure? Well, they have to build big natural gas pipelines from somewhere into this tiny town in the middle of nowhere. They have to rip out the coal boiler and generators and replace them with “hydrogen ready” natural gas generation units. They have to build a lot of renewables around the town somewhere and transmission into the town to bring all of those green electrons to it. They have to build a massive industrial green hydrogen electrolysis facility in the town. They have to seal some natural caverns under the town and turn them into a huge geological hydrogen store that doesn’t leak much.

In operation, they have to take the useful green electricity and throw away a bunch of it to turn it into hydrogen. When they put the hydrogen into the “hydrogen ready” gas generation units. This turns cheap electricity into expensive electricity.

This does preserve some power engineers and administrative jobs, but all the coal miners are out of work. All of the people who know how to run a coal plant have a lot of retraining before they can run a gas plant, and a lot more before they could run a hydrogen plant and storage facility. The timing suggests most of them will just retire instead of transitioning, to no human resource benefit whatsoever.

Why, by the way, do I keep putting “hydrogen ready” in quotes? Because most of the time natural gas burning units are hydrogen ready like your driveway is Lamborghini ready. That it’s possible to park a fictitious future and very expensive Lambo in it does not in any way mean that you will be able to afford to do so.

What does all this hydrogen nonsense have to do with small modular reactors? Well, coal towns look at SMRs as a convenient technology to dump on the coal plant site. That actually makes more sense than the Rube Goldberg hydrogen nonsense, if SMRs were a solution. As Shah and others keep pointing out, coal plants already have big areas, security and transmission.

But coal plants don’t have seven layers of overlapping security, with five layers inside the state. Fences at coal plants are to keep thieves, drunk people and Greenpeace protestors out, not much more. Nuclear facilities have federal oversight and security and military level ordnance onsite.

Nonetheless, expect lots of nonsense.

In the USA, the devolution of the ability to say no to the individual

Back to the US DOE. Why is it giving $504 million to a clearly ludicrous scheme whose only merit is keeping a tiny rural town with no future alive? In the USA, they’ve lost the ability to do big infrastructure. The political scene has devolved the right to say no down to the county and often the individual level.

As such, the only things that the US DOE can fund with loans are things which have already received that hyperlocal support. Bizarre assembled blocks of this and that like the Delta hydrogen play are the result, not rational regional transmission infrastructure for wind and solar, electrifying rail and an acceptance of sunk costs.

Instead of learning the primary lesson of the hollowing out of various parts of the USA due to the combination of China and automation eliminating factory jobs over the past 40 years, which is that paying people to leave dying towns in a combination of relocation funds, a social safety net, retraining and support in their new community, the USA is stuck with faint hope plays to keep the dying towns alive. For a good presentation of this, the great book Good Economics for Hard Times by Banerjee and Duflo has a good section on the very effective and very poorly funded Trade Adjustment Assistance program. Dying towns are a lot stickier than classical economics indicates, and how to deal with them is now well understood but politically unpalatable.

Compare this to the New Deals during and after the Great Depression. Massive dams. Massive transmission. The interstates. Hugely positive transformation programs run by the government. Not allowed in 21st Century USA. Of course, lots of inequity in those programs as well.

This is playing out in smaller rural centres around the developed world. Automation has radically reduced human labor requirements for extraction industries like mining and agriculture. There are fewer and fewer jobs in rural areas every decade. Cities are where people have significant economic, social and marital opportunities. Increasingly the people in rural areas are the ones without the ability to change and take risks, simply because anyone who can think remotely strategically and has the slightest degree of acceptance of risk leaves as soon as possible.

Combine the irrationality of dying towns and counties with the ability for those counties and the states that they are in to block actually sensible transformation, and the US DOE ends up giving loans that will provide hope but no other value.

Hence the madness driving small modular nuclear reactors

It’s easy to see that assembling a group of stakeholders sufficiently large to create the appearance of movement and success out of these diverse organization isn’t necessarily trivial, but is certainly possible. NuScale found willing partners in an overlap of this space. They had the US Department of Energy giving them lots of money. The US DOE also donated a bunch of space on a DOE nuclear-oriented national lab’s grounds in neighbouring Idaho. It included the Utah Associated Municipal Power Systems (UAMPS) organization as a sponsor to get a bunch of small Utah cities and towns aligned to buy the electricity.

Utah and Idaho are both hardcore Republican states, so that was an easy sell. Utah Senator Mike Lee is so strongly opposed to climate action that he brought flip boards with images of Ronald Reagan riding a dinosaur to Congress to attack the proposed Green New Deal.

NuScale found some Wall Street SPAC money guys who were excited at the thought of pumping and dumping the stock of the company, which they succeeded in doing in August of 2022. NuScale’s market capitalization is off 80%, but rest assured, the SPAC founders made out just fine, leaving the follow on retail investors holding the bag.

This is a coalition of deeply motivated thinkers and organizations piling hope upon fantasy upon irrationality upon ideology upon venality. The odds of NuScale succeeding were always slim to none. This is true for every SMR proposal out there.

This article is archived and lightly updated from an earlier CleanTechnica analysis.

Note: this is a lightly updated version of a five year old article, but the conclusions haven’t change. For the most up-to-date perspective, read SMRs still lack the discipline nuclear scaling requires.

Like hydrogen, small modular nuclear reactors have been seeing a resurgence of interest lately. Much of that is driven by governmental policies and investments focusing on the technology. Much of it comes from the nuclear industry. And inevitably, some comes from entrepreneurs attempting to build a technology that they hope will take off in a major way, making them and their investors a lot of money.

Small modular reactors won’t achieve economies of manufacturing scale, won’t be faster to construct, forego efficiency of vertical scaling, won’t be cheaper, aren’t suitable for remote or brownfield coal sites, still face very large security costs, will still be costly and slow to decommission, and still require liability insurance caps. They don’t solve any of the problems that they purport to while intentionally choosing to be less efficient than they could be. They’ve existed since the 1950s and they aren’t any better now than they were then.

Most Of The Attention & Funding Is Misguided At Best, & Actively Hostile To Climate Action At Worst

First, let’s explore briefly the world of small modular nuclear reactors (SMNR) or small and medium reactors (SMR). The most common acronym is SMR, but you’ll see both.

As it says on the box, they are nuclear generation devices, specifically fission nuclear. That means they use radioactively decaying fissile materials, fuels, to heat a liquid which creates steam which drives steam turbines to generate electricity. Technically, they are like a coal generation plant, but with the heat provided by the decay of uranium instead of the burning of long-buried plant matter.

There are a handful of differences between them and traditional nuclear generation reactors. The biggest one is that they are smaller, hence the ‘small’ and ‘medium’ in the names. They range from 0.068 MW to 500 MW in capacity, with the International Atomic Energy Association using small for up to 300 MW and medium for up to 700 MW.

Despite the buzz, this is not new technology. The first nuclear generation plant was a Russian 5 MW device that went live in 1954. Hundreds of small reactors have been built for nuclear powered vessels and as neutron sources. This is well trodden ground. Most of the innovations being touted were considered initially decades ago.

In the seven decades since the first SMR was commissioned, 57 different designs and concepts have been designed, developed and, rarely, built. Most of the ones which are built are doing what nuclear reactors do, getting older without new ones being built to replace them.

The Russian models are far-north icebreaker power plants being considered for land-based deployment in remote northern towns, with the Siberian one at end of life. The Indian ones are 14 small CANDU variants in operation, most decades old now. The Chinese one is coming up to end of its 40-year life span as well.

The Argentinean model has been in construction on and off for over a decade with work stoppages, political grandstanding, and monetary problems. It may never see the light of day.

The Chinese HTR-PM, under construction for the past decade, is the only one with remotely new technology. If commissioned, it is expected to be the first Gen IV reactor in operation.

And to be clear, this isn’t a technology, it’s many technologies. Across the decades, 57 variants of 18 types have been put forward. None of the types can be considered to be dominant.

Claims About SMRs Don’t Withstand Scrutiny

Advocates for SMRs typically make some subset of the following claims:

• They are safer

• They can be manufactured in scaled, centralized manufacturing facilities so they will be cheaper

• They can provide clean power for remote facilities or communities

• They can be deployed onto decommissioned coal generation brownfield sites

• They can be built faster

None of these are actually good arguments.

First, traditional nuclear is safe already, dominantly due to passive safety features in the majority of operational reactors and lots of attention to management and operations. Chernobyl was a bad design. Fukushima was deeply bad siting and operational decisions. Those siting and operational decisions have resulted into a cost which is likely to be around a trillion US Dollars to the overall Japanese economy when all the bills are counted. SMRs aren’t immune to bad siting and bad operational decisions, but there have been some lessons learned by the industry.

Safety concerns aren’t why nuclear is failing in the marketplace, economics are why nuclear is failing in the marketplace.

Second, in order for economies of scale to kick in, a manufacturing facility has to build hundreds or thousand or millions of the same thing and have a projected future market for hundreds or thousands more. The field is littered with 18 different types of technologies and many competing designs within those types. There is no coherent single technology which will dominate the field. Each country engaged in SMR research has its own preferred technologies and its own companies to support.

In order for any of these designs to see economies of scale, several major countries would have to get together, decide on a single specific technology, form a joint venture with the manufacturer, and commit to building and deploying only that technology. This isn’t a market-based solution, it’s not aligned with the geopolitical strategies of the countries, and so none of these designs will scale beyond perhaps the 14 units of the old CANDU derived Indian design.

Russia is serious about icebreaker and landed small reactors, but Russia isn’t going to shape a global market for them. They might build a few in far northern communities, with predictable concerns. China is the only country doing significant expansion of nuclear generation, and it’s already closing in on double-digits of technology variants, a failure condition. The US could re-focus on small PWRs, but there’s no particular political will at the federal level to push for that.

No scaled manufacturing, no cost reductions. Nu Scale’s expressed hope is to get its cost of generation down to only double the current wholesale cost of wind and solar generation, around $65 per MWh.

Third, both remote communities and brownfield coal generation plants have major security exposures. As nuclear technologies and fuels are highly proscribed and limited due to nuclear non-proliferation strategic goals, and as concentrated radioactive material is highly desirable for terrorists for dirty bombs, the entire supply, operational and waste chain requires significant overlapping circles of defense.

These requirements don’t go away because the nuclear reactors are smaller.

And these security costs are big, and mostly hidden in federal, state, and municipal subsidies. Remote areas still require these additional security costs, and they will likely be higher simply due to the additional challenges of securing remote areas with high transportation costs. Brownfield coal generation sites don’t become more economically viable with massive security upgrades and unproven technologies.

Without economies of scale, there will be no fast deployment of SMRs. They need to be standardized, shippable units. Right now, the units under construction and Nu Scale are on track for the median of a decade for construction. Nu Scale is promising 12 units in operation by 2029, but the $1.4 billion bail-out it received after several municipalities walked away from the rising costs and schedule don’t suggest that’s realistic.

Are There Other Problems With SMRs?

Yes, yes there are, three of them.

First, they don’t take advantage of vertical scaling. As discussed, they are highly unlikely to achieve economies of scale of manufacturing due to the sheer number of competing technologies and the lack of any strategic imperative to resolve that issue. But in addition to that horizontal scaling challenge, they don’t scale vertically either. Thermal generation units get more efficient as they get bigger, up to a point. That’s why most coal and nuclear generation is closer on a per boiler or reactor basis to a GW of capacity, not a third of that. There are technical reasons for this, but some of it has to do with the optimum diameter of pipes for most efficient fluid and steam transfer compared to the materials required for them. Bigger diameter pipes move a lot more fluid without nearly as much material. SMRs forego those efficiencies of vertical scale. Amusingly, Gates’ Terrapower is designing a 1,200 MW capacity reactor, so they seem to have received the vertical scaling memo. Of course, that just puts them back into the same cost problem as normal reactors.

More of it has to do with with the units requiring all the same components as full scale reactors, but them being much smaller and more labor intensive to fit together per MW of capacity. The rule from modular chemical processing plants is to first make each module as big as possible, then built multiple of them.

Second, decommissioning a nuclear reactor is a billion dollar, 100-year venture. That’s been shown empirically by reactors under decommissioning in several countries. The US hold back accounts for roughly a third of those costs, so the tax payer will be on the hook for the rest, about $70 billion. SMRs will require the same duration and proportional cleanup costs. Taking the Nu Scale deployment, there are intended to be 12 60 MW reactors for a total of 720 MW of capacity. That suggests in the range of $720 million for cleanup. While I’m sure SMR advocates expect the reactors to be returned to a centralized processing site for decommissioning, no country in the world has managed to build a centralized nuclear waste repository, so this premise is deeply unlikely.

Third, no nuclear reactor is commissioned with private insurance alone. Every country with a nuclear generation fleet has enacted legislation which caps private liability at some level, and puts any liability above that level onto the shoulders of taxpayers. In the US at present that’s $13 billion. It sounds like a large number, and it is but as was pointed out earlier, Fukushima’s total liability is in the trillion USD range. The number of countries willing to sign up for that liability is shrinking globally, not growing.

So Who Is Advocating For SMRs & Why?

At present we see SMR earmarked funds in both Canadian and US federal budgets, $150 million in Canada and 10 times as much in the US, mostly for research and development with the exception of over a billion to NuScale to, in theory, build something. In Canada, four provinces — Alberta, Ontario, New Brunswick and Saskatchewan — have joined forces in an SMR consortium. Bill Gates’ Terrapower has received another $80 million, as has X-Energy from the US DOE.

The failure conditions of small modular reactors are obvious. The lack of a significant market is obvious. The lack of ability to create a clear winner is obvious. The security costs are obvious. The lack of vertical scaling to thermal efficiency is obvious. The security risks and associated costs are obvious. The liability insurance cap implications are obvious. So why is all of this money and energy being thrown at SMRs? There are two major reasons, and only one of them is at all tenable.

Let’s start with the worst one. The Canadian provinces which are focused on SMRs are claiming that they are doing this as a major part of their climate change solutions. They are all conservative governments. Only one of those provinces has a nuclear fleet, although New Brunswick has one old, expensive, and due-to-retire reactor, as well as a track record of throwing money away on bad energy ideas, like Joi Scientific’s hydrogen perpetual motion machines. One of the provinces, Ontario, has been actively hostile to renewable energy, with the current administration cutting up 758 renewables contracts and legislating a lack of recourse as a very early act after election.

So why are they doing this? Because it allows them to defer governmental climate action while giving the appearance of climate action. They can pander to their least intelligent and wise supporters by asserting that renewables aren’t fit for purpose, while also not doing anything about the real problem because SMRs don’t exist in a modern, deployable, operable form yet.

The other major reason gets back to renewables as well. 15 years ago it was an arguable position to hold that renewables were too expensive, would cause grid reliability issues and that nuclear in large amounts was necessary. That’s been disproven by both 15 years of failures of nuclear deployments, but more importantly plummeting costs and proven grid reliability with renewable generation. Now almost every serious analyst agrees that renewables can economically deliver 80% of required grid energy, but there is still debate from credible analysts about the remaining 20%.

Mark Z. Jacobson and his Stanford team are at the center of this debate. Since the late 2000s, they’ve been publishing regular studies of increasing scope and sophistication on the thesis of 100% renewables by 2050. The 2015 publication saw a lot of pushback. At the time, my assessment of the fundamental disagreement was that the people who published a criticism of it thought the last 20% would be too expensive, and that both nuclear and carbon capture and sequestration would be necessary and scaled components.

Personally, I’ve done various aspects of the math, looked at grid reliability and transformation data from around the world, and looked at ancillary services requirements, and I think Jacobson and team are right. Further, that since we all agree that renewables are fit for purpose for 80% of the problem we should deploy them as rapidly as possible.

However, it’s very reasonable to make a side bet or two to ensure coverage of that last 20%. I don’t mind research dollars spent on SMRs, which is all most of the SMR expenditures amount to, outside of the Nu Scale bailout (which is added to the Ohio $1.3 billion bailout, which is added to the annual $1.7 billion overt federal subsidy, which is added to the annual hidden $4 billion security subsidy which is added to the $70 billion unfunded cleanup subsidy, which is added to the uncosted and unfunded taxpayer liability). Spending a few tens of millions of dollars in rich countries to ensure that we have that last 20% bridged is reasonable.

But the people asserting that SMRs are the primary or only answer to energy generation either don’t know what they are talking about, are actively dissembling or are intentionally delaying climate action.

This article is archived and lightly updated from an earlier CleanTechnica piece. It also exists as a peer-reviewed paper on De Gruyter Brill and chapter of the textbook Green Chemistry: Advances in Alternative Energy.

Octopus laid out the European plan directly. Swaptopus is intended to be an automated battery-swapping network across Europe for electric trucks. An electric lorry pulls into a hub, the depleted battery is replaced within minutes, and the truck gets back on the road instead of waiting through a charging session. Octopus says CATL already has more than 300 battery-swapping stations in China, and Greg Jackson’s most important point was about route structure: trucking companies often run defined routes, which means stations can be placed where those trucks need to swap.

The European warning is not sovereignty. It is speed. China’s official 2030 plan is already an operational floor: new-energy heavy trucks at 40% penetration, more than 1.6 million in stock, roughly 3,000 heavy-truck charge and swap stations, and 30,000 km of zero-carbon freight corridors. CATL and Sinopec are aiming above that floor, not waiting for it. CATL brings battery scale, Qiji’s 75# swap-block architecture and OEM alignment. Sinopec brings energy retail sites, operational reach and the logic of refuelling infrastructure. Swaptopus brings the same direction of travel into Europe.

If Europe’s response is cautious charging deployment, slow standards work and OEM hesitation, the market will move around it. Fleet operators do not need a perfect European consensus. They need trucks that can run routes, refill energy quickly, preserve uptime and make economic sense. If CATL and Swaptopus make that easier first, their interface becomes the market default. European OEMs then risk being forced to build around someone else’s battery geometry, state-of-health data, lease structure and route-energy system.

Europe has ambitious heavy-truck CO₂ rules and serious charging regulation. That is not the same thing as moving fast enough to electrify freight operations. Targets and access rules matter, but freight operators buy uptime, cost control and route confidence. China is assembling vehicles, batteries, routes, stations, data and finance into an implementation system. Europe is still at risk of treating trucking electrification as a charger-rollout problem.

That defined-route point matters. Repeated freight patterns are where electric-truck infrastructure becomes buildable: standard sites, standard energy increments, known dwell points and fewer one-off designs. In my 2025 report with Rish Ghitikar The New Logistics: Electrifying Freight with Microgrids, the core argument was that the hard problem is reliably getting clean electricity into trucks, with modular, incrementally scaled infrastructure as the answer. Qiji shifts that logic one layer deeper: the repeatable unit may be the battery block, station inventory and control layer, not only the charging site.

Swaptopus is therefore not just a European swapping announcement. It is the European entry point into a larger platform question: what happens when battery geometry, chassis interfaces, station mechanics, battery inventory, state-of-health data, leases, insurance, residual value, energy procurement and software dispatch are bundled into a freight-energy system?

The easiest European framing is to make this a swapping-versus-charging story. That misses the strategic layer. Europe already has charging rules, heavy-duty vehicle CO₂ rules, battery law and serious megawatt-charging actors. The Qiji signal is different because it asks who defines the truck-energy interface. If the answer comes from the firms that standardize the battery block, station mechanics, data layer, leasing model and commercial terms, European policy and OEM strategy will be reacting to market defaults, not shaping them.

CATL’s Qiji pathway sits above China’s official floor as a platform ceiling. CATL says the pathway uses a standardized 75# battery-swap block, which should be read as a heavy-truck swap-block format rather than a published kWh specification. CATL has not disclosed public dimensions, weight or energy capacity for the 75# block in the release. Octopus’s Swaptopus announcement refers to a 500 kWh truck battery swapped in minutes. That makes the operating scale clear enough for this review: this is heavy-truck battery inventory, not passenger-car pack swapping.

CATL targets 150,000 km of Qiji route coverage by 2030, aims at 80% of trunk transportation capacity, has more than 30 chassis-swap models across more than 10 OEMs, had 305 commercial or truck swap stations built by the end of 2025, and is targeting 900 stations in 2026. Those numbers matter because they describe a platform ambition, not because station count alone proves freight capacity.

Sinopec changes the reading. A battery company can define a pack. A battery company paired with a national fuel-station giant can define a refuelling architecture. That does not prove utilization or economics, but it materially improves the platform conditions: sites, grid interconnection experience, energy retailing, fleet relationships, operations discipline and state-aligned capital. This is why Qiji should not be read as a station-count story. CATL and Sinopec’s broader 10,000-station battery-swapping partnership includes passenger-vehicle choco-swap technology and Qiji chassis battery-swapping for heavy-duty trucks; it should not be misread as 10,000 Qiji heavy-truck stations, but it is a clear statement of direction and scale.

For policymakers and transportation strategists, the task is not to copy Qiji. It is to make Europe’s own electrification pathway operationally serious enough that fleets do not simply adopt the fastest workable imported answer. For truck OEMs, the risk is more direct. If a battery-swap platform owns the battery geometry, station access, battery-health data, lease terms, insurance logic, residual-value pathway and route-energy software, the OEM risks becoming the chassis supplier inside someone else’s freight-energy platform.

For paying subscribers, the rest of this pathway review goes under the surface of the announcement: what is solid evidence, what is CATL ambition, what is TFIE inference, and what still has to be proven. It includes the companion workbook, China’s policy floor, CATL’s Qiji platform ceiling, the New Logistics fit test, the Flyvbjerg modular-native argument for the 75# block, the denominator problem behind the 305-station figure, the managed-charging economics of swapping, the European market-default risk, the full pathway scorecard and the update triggers that would change the verdict.

The Gezhouba, a new 13,000-ton all-electric bulk carrier launched in Yichang, China, is more than a technical milestone. It is a sign that the electrification of inland shipping is moving from concept to inevitability. The vessel’s 24 MWh of containerized lithium battery modules can move cargo roughly 500 km on a single charge per the launch announcement, and its home port already hosts the first dedicated charging station on the Yangtze River. For years, analysts have speculated that the physical scale of bulk carriers would make batteries impractical. Now the question is no longer whether electric bulk transport can work, but how quickly the infrastructure will spread to support it.

Port electrification follows a predictable sequence. The first stage replaces diesel cranes, trucks, and yard equipment with electric systems. The second extends to tugs and harbor craft. The third, which is now underway in China, reaches inland and short-sea vessels. The fourth will see ports functioning as full energy hubs, feeding deep-sea hybrids and stabilizing regional grids. Every stage builds on the one before it. Once the ground vehicles and cranes switch to electric drive, high-capacity chargers and energy management systems are already in place. Those same assets can serve harbor craft and ships. Electrification propagates by infrastructure reuse.

The Yangtze River has become a living demonstration of this process. It connects the interior manufacturing centers of Chongqing, Wuhan, and Yichang with the export hubs of Shanghai, Nanjing, and Ningbo. Along its length, the physical river has been matched by a set of electrical arteries. Two of them, the Changji–Guquan and Hami–Chongqing UHVDC transmission lines, deliver more than 30 TWh of renewable power each year from the deserts and plateaus of the west to the dense industrial east. Together they provide up to 8 GW of clean capacity directly into the Yangtze corridor. These ultra-high-voltage direct current lines are the spine of a new energy geography, making clean electrons available where cargo and industry already cluster. Without that grid backbone, even the most efficient electric ship would be an isolated experiment.

Yichang, where the Gezhouba was built, has become one of the first inland ports to integrate ship charging into its grid operations. The facility’s 800 kVA shore connection powers both stationary equipment and vessels. A smaller network of similar stations now stretches along mid-river ports handling bulk materials like ore and aggregates. Farther east, the delta ports are evolving faster still. Shanghai, Jiangsu, and Zhejiang are co-locating offshore wind with platform-based offshore solar and large battery banks. Jiangsu’s Rudong complex pairs 400 MW of offshore PV with grid-scale storage. Ningbo and Zhoushan have already replaced diesel power for cranes and heavy cargo gear, reporting tens of GWh of electric energy delivered to port operations each year. These changes make the delta ports partial power plants, capable of feeding ships, vehicles, and local industry from the same renewable base.

The Gezhouba itself is built around twelve modular battery units packaged in steel boxes roughly the size of shipping containers. Each contains immersion-cooled lithium cells suspended in silicone oil for safety and temperature control. The modules can be charged in place or swapped out entirely at a port. This approach mirrors the 700-TEU Yangtze container ships already in service that exchange standardized battery containers at dedicated swap stations. Standardization matters because it allows operators to share infrastructure, spreading costs across multiple fleets and shortening turnaround times. In design and operation, the new bulk carrier follows the same logic that has already worked for smaller container ships and ferries. Predictable routes, steady loads, and controlled terminals make electric propulsion an economic choice rather than a demonstration.

Bulk carriers are often considered poor candidates for electrification because of their energy intensity, but inland routes have different constraints than ocean crossings. River vessels spend much of their time at low speeds, stop frequently, and operate between fixed terminals. Those characteristics make energy demand manageable and allow recharging or battery exchange to fit naturally into loading cycles. The Gezhouba’s route between Yichang and downstream industrial zones is exactly the kind of steady corridor where battery freight makes sense. Its performance data will shape the specifications for the next generation of inland bulk carriers, which will likely standardize on containerized modules, automated docking, and shared charging infrastructure.

There are still gaps to close. The battery modules must be standardized across manufacturers, with compatible cooling, interlocks, and communication systems. The supply chain for lithium cells, power electronics, and large converters must expand to support a fleet rather than a prototype. Smaller river ports need grid reinforcements and on-site storage to handle charging peaks. These are not technical barriers but sequencing problems. Each requires coordination between shipbuilders, utilities, and port authorities, not new physics. In that sense, the challenges resemble the early years of electric trucking and aviation, where infrastructure growth followed successful pilot routes rather than preceding them.

Viewed in the larger context of maritime energy, the Yangtze experiment sits within a clear global trend. Inland and short-sea shipping will electrify almost completely by mid-century, while deep-sea vessels transition more slowly through hybrid designs. Battery density and cost curves already favor routes under 1,000 km. As ultra-high-voltage transmission and local renewable capacity expand, the line between port infrastructure and power generation blurs. Ports are becoming nodes in a continental electrical system. They no longer only move cargo but balance supply and demand for regional grids.

This is against a backdrop of radical change in shipping volumes. 40% of all tonnage is of fossil fuels and all are in structural decline. Another 15% is raw iron ore, also in structure decline. Population growth is slowing and the global population is expected to peak between 2050 and 2070. While container shipping will continue to grow, it won’t be growing nearly as fast as bulks decline.

What is happening along the Yangtze suggests how this will evolve elsewhere. Europe’s Rhine corridor, North America’s Mississippi system, and Southeast Asia’s Mekong delta all have the same combination of dense trade, predictable routes, and nearby renewable resources. Once reliable electric power reaches the terminals, electrification of the vessels themselves follows almost automatically. The Gezhouba is not an outlier but an early arrival.

The end state is easy to describe even if it will take decades to reach. Ports will act as energy hubs that receive renewable electricity through long-distance HVDC lines and distribute it through local solar, storage, and charging systems. Every vehicle, crane, and ship in the port ecosystem will run on electricity. Some ports will also feed power back to the grid during high demand periods. Inland shipping will be entirely electric, coastal routes mostly so, and only transoceanic freight will depend on hybrid systems with combustion as backup. The river that once carried coal and oil will carry the power that replaces them.

No one can claim to be entirely right about the pace or order of these transitions. I do claim to be less wrong than many. Energy systems evolve through trials and feedback, not linear plans. But it is becoming clear which directions are durable. The Gezhouba’s quiet launch on the Yangtze is a reminder that once the electricity is clean and the grid is strong, moving freight by battery is not just possible. It is the default waiting to be recognized.

The Port of Long Beach’s latest clean-technology announcement looks evasive at first glance. The release keeps saying “zero-emission,” while avoiding the simpler phrase battery-electric. In California port policy, that is enough to make a hydrogen skeptic check the small print twice. California has a long habit of keeping hydrogen in the policy tent long after the operating evidence has become unkind to the molecule.

But the useful reading is not that Long Beach is hiding a hydrogen strategy inside a cargo-handling program. The useful reading is almost the reverse. The Port is using technology-neutral language while the funded assets are increasingly electric. That is how pragmatic institutions retreat from hydrogen without saying so directly.

The denominator is not the word zero-emission. The denominator is what is being bought, installed and made easier to procure next. In the Long Beach package, the cargo-handling side includes zero-emission human-operated equipment and chargers. Chargers are not a neutral technology platform. They do not support hydrogen top handlers, hydrogen yard tractors or hydrogen forklifts. They support electric equipment, electric maintenance routines, electric depot planning, electric interconnection work and the next round of electric procurement.

This matters because “zero-emission” is doing at least three jobs at once. It is a regulatory category, a grant-program category and a coalition-management term. California agencies, ports, terminal operators, OEMs, truck fleets, fuel suppliers and elected officials have all spent years using zero-emission as the broad tent under which both batteries and hydrogen could stand. That language made some sense when evidence was thinner and the political coalition was easier to hold together than the infrastructure plan.

The problem is that technology-neutral language has started to obscure technology-specific deployment. Batteries and hydrogen are not two interchangeable ways of powering the same future port. Battery-electric cargo-handling equipment extends the power system into a terminal. Hydrogen fuel-cell equipment requires a parallel fuel system: production, delivery, storage, compression or liquefaction, dispensing, safety management, fuel quality control, station maintenance and sufficient utilization to make the whole chain something other than an expensive demonstration.

That systems difference is the fulcrum. It is not enough to ask whether a hydrogen machine can move a container. A prototype can do many things once. The real test is whether the equipment class exists commercially, whether it is being bought repeatedly, whether the infrastructure serves more than a demonstration fleet, whether uptime is good enough for port operations, and whether the delivered cost competes with plugging equipment into an increasingly electrified terminal.

The California Air Resources Board’s (CARB) own draft 2025 cargo-handling equipment assessment makes the asymmetry visible. It finds no commercially available hydrogen fuel-cell container cargo-handling equipment, while the listed hydrogen fuel-cell yard trucks and several container-handling categories remain in development or demonstration rather than commercial deployment. That does not mean every battery-electric category is already mature. Some electric port equipment still has lead-time, uptime, charging-window and infrastructure constraints. But the battery-electric pathway is working through commercialization problems. Much of the hydrogen pathway is still trying to earn the right to have commercialization problems.

That distinction explains the language. Long Beach does not need to announce that hydrogen has failed. It does not need to irritate Sacramento, Washington, hydrogen suppliers, demonstration partners or terminal operators that have grants attached to hydrogen projects. It can keep using the approved phrase zero-emission while putting money into chargers and electric equipment. The public language preserves optionality. The physical assets narrow it.

There is still backslide risk, especially because this is California. Hydrogen remains politically durable in drayage trucking, rail demonstrations and fuel-subsidy programs. A zero-emission locomotive could still become a hydrogen demonstration. A truck incentive can still subsidize hydrogen fuel long after battery-electric drayage has become the more obvious system answer for many routes. A port can still fund a hydrogen pilot because pilots are easier to defend than scaled procurement and because “optionality” remains one of the most expensive words in clean-transport policy.

But the risk is not evenly distributed. For this cargo-handling tranche, the hydrogen risk is low because chargers and terminal electrical upgrades are hard assets. They create institutional learning, maintenance familiarity, procurement confidence and charging routines. Once a terminal has invested in that base, the next electric purchase becomes easier and the next hydrogen purchase has to justify not only the vehicle, but the whole fuel chain beside it.

For drayage trucks and rail, the risk is higher. Those sectors still attract hydrogen arguments because range, duty cycle, refuelling time and corridor coverage can be framed as reasons to avoid charging complexity. Some of those constraints are real. But the comparator is not diesel-like refuelling in the abstract. The comparator is battery-electric trucks plus depot and corridor charging, against hydrogen trucks plus production, distribution, dispensing, fuel cost, station reliability and subsidy dependence. Hydrogen has to beat the whole electric system, not just point to a larger battery and declare victory.

That is the professional takeaway from Long Beach. Follow the assets, not the adjectives. A press release can say zero-emission for political, regulatory and grant-alignment reasons. A procurement program reveals more when it specifies chargers, grid work, electric equipment classes and repeatable operating assets. Announcements are soft. Infrastructure is harder. Utilization will be harder still.

Ports are not going to exit hydrogen with a press conference called “we were over-optimistic about molecules.” They will exit by installing chargers, training maintenance teams, upgrading electrical systems, revising terminal workflows and buying the next electric unit because the previous one worked well enough. The hydrogen language will linger after the capital strategy has moved on.

That is not hypocrisy. It is transition diplomacy. The cleanest reading of Long Beach is that the port is preserving the political umbrella while the operational pathway becomes increasingly electric. Hydrogen advocates can still point to the word zero-emission and claim the door is open. They are not wrong. But an open door is not a deployment pathway, and it is not a charger.

Cabotage acts are sabotage for maritime decarbonization. Well, that rhymes, but what does it mean? What is cabotage and why are Europe and the USA more impacted than Asia? It’s a tangled tale and we have to go back over a hundred years to unravel the story and its implications.

Let’s start in the future, however. When shipping is decarbonized, at least in my admittedly heterodox scenario, all inland and most short sea shipping will be running on batteries. Long haul coastal shipping and transoceanic shipping will be running on biofuels, mostly biomethanol and ethanol, with hybrid battery systems for near shore and port operation. Much of these batteries will be containerized, hoisted off ships to be charged on shore with new batteries dropped into waiting holds. Some will be built-in, especially for bulk carriers, with electron bunkering barges and shore connected charging buoys providing electrons while ships are moored.

This chart from my scenario captures the end state. I assembled statistics on inland, short sea, and deep water shipping from 1990 to 2025, including the COVID-19 dip. My scenario respects that 40% of cargo shipping is of coal, oil, and gas and assumes that we will be reducing significantly shipping of those substances, in alignment with the International Energy Agency’s projection of declining demand, but contrary to the beliefs of the fossil fuel industry. Further, the 15% of cargo tonnage that is raw iron ore are going to diminish as economics move iron and steel manufacturing closer to mines, powered by renewably generated energy, and with reduction from green hydrogen or electrolysis. Maritime growth areas are dominated by segments much more amenable to electrification.

It respects the flattening of population growth with an assumed peak between 2050 and 2070, aligned with a couple of major demographic organizations, but not the UN’s, which while it’s brought peak back to the 2080s and reduced peak population in its 2022 forecast, is still pessimistic compared to very strong alternatives.

It respects that China’s growth boom is flattening and that other developing nations such as India, Indonesia, and Brazil do not have the conditions for success for the rate of economic growth that China saw from 1990 through the present. This is not, however, a China-is-doomed narrative, but simply a reflection that the economic conditions of the world are changing and that China’s growth is in a different phase.

In this scenario, peak demand for HFO-equivalent burnable fuels is roughly 70 million tons in 2100. This contrasts with common projections of 350 million tons in 2050, which leads to systemic attempts to make green hydrogen unfathomably cheap in contradiction of the basics of the technology, electricity supply, and economics. My scenarios preserve green hydrogen for ammonia fertilizers, steel, and other industrial chemical feedstock use cases, outside of rounding error scenarios where there is waste hydrogen from processes such as chloralkali electrolysis that have no other value but to be burned for nearby process heat.

But that’s a lot of battery-powered ships to go with the ones burning biodiesel. And that’s a lot of hybrid-electric drivetrains in longer haul ships. Who is going to build them? Where are the batteries going to come from?

The United States & The Jones Act

Let’s now cast our minds back to 1920. World War I had just ended. As with World War II, where Japan’s deep strategic mistake of attacking Pearl Harbor led to the US entering the war as a decisive force, the US had remained neutral through the first three years of World War I, supplying goods, materials, and ammunitions to both sides equally in the early part of the war.

Britain’s naval blockade of goods to the Central Powers of the German Empire, Austria-Hungary, the Ottoman Empire, and Bulgaria saw US merchant ships attempting to deliver materials turned back. As a result, war supplies to the Allies became the dominant economic opportunity and so US merchant marines pivoted to supplying them much more.

The German Empire made one significant strategic mistake and one debatable one. The significant mistake was attempting to create a military alliance with Mexico against the US, a significant overreach of capability. The debatable mistake was having their U-boats attack and sink American merchant marine vessels to cut off supply chains to the Allies.

The combination, plus undoubtedly a multitude of other factors, led to the US entering the war on the side of the Allies and playing an important and decisive role in the Allied victory. That, of course, led to the terrible mistakes in dealing with the losing countries that arguably led fairly directly to World War II, but that’s a somewhat different story.

The thread we want to pull on is the merchant marines and their decisive role as a logistics arm of the US navy. At least from the US perspective, without the merchant marines, the war would have been much harder to execute. After the war, discussions around it led to the creation of the Jones Act, formally the Merchant Marine Act of 1920.

The Jones Act is a controversial piece of legislation and unsurprisingly, I’m going to come down on a side about it. What is surprising is that apparently I agree with the Cato Institute, that far-right Libertarian think tank that’s equal only to the Heritage Foundation in working to make America’s political, economic, and industrial policies dystopian servants of oligarchic wealth.

Yes, we both think that the Jones Act should be at minimum heavily reformed and likely abolished. I’m not going to bother to parse the Cato Institute’s arguments because the odds of them having sufficient overlap with my perspective of reality means that I’ll likely be unable to appreciate the rich nuances that only devoted fans of Ayn Rand and the worst readings of Milton Friedman will see in it. Instead, I’ll make my arguments here.

The Jones Act is a cabotage act, that is, legislation which restricts various aspects of coastal shipping to domestic carriers. It’s the most restrictive cabotage act of any major economy. It requires that all cargo ships sailing between American inland or coastal ports must be made in American shipyards, be registered in the USA, be owned by American firms, and be crewed by Americans. This applies to bulk carriers, tankers, and container ships. It applies to ferries and cruise ships. It applies to tugboats, fishing vessels, research vessels, and offshore support vessels.

Yes, this is a deeply protectionist act in one of the world’s leading promoters of free trade. Remember that the reason for the Jones Act was to maintain a strong merchant marine in the event of war, enabling logistical supply of both allies and of American military forces.

Let’s fast forward to today. As of 2022, there were only 93 oceangoing container ships, tankers, and roro vessels above 100 tons that complied fully with the Jones Act. Only a subset of those 93 ships are militarily useful. They are smaller coastal vessels which aren’t going to be crossing the Pacific or Atlantic except under duress. They aren’t Panamax tankers or 24,000 TEU container ships. They are small and often into their senior years as shipping vessels.

There are 299 active significant US naval warships in active service. The US maintains hundreds of military bases around the world, far out of reach of Jones Act registered ships. The world’s logistical supply chain has matured radically since 1920 and post-World War II. Ships are much bigger, ports are incredibly efficient loaders and off-loaders of goods, and globalization means that the US’ merchant marine ships are a rounding error.

Given that I have a perspective on commercial maritime shipping and pay attention to geopolitics, I see a lot of pearl-clutching and handkerchief-wringing among US maritime types about the challenges with getting war materiel to conflict zones. I also see most of the same people defending the Jones Act. The cognitive dissonance is powerful.

If the Jones Act had enabled the US to maintain a strong merchant marine, then it would have an argument for it. Clearly it didn’t succeed in that regard, although it’s not alone in causing US shipbuilding capacity and competence to wither outside of military vessels where budgets are abstract and often surreal. No, the post-World War II world order that the US was so instrumental in bringing to bear led to significant increases in global trade mechanisms and freer trade. It included the growth of not only the Asian tigers, including South Korea and Japan, but subsequently China itself.

The world’s shipbuilding industries moved to Asia. China is by far the world’s largest shipbuilder, with 44% of the world’s market in 2021. South Korea follows with 32%. Japan, which dominated for a while, is now in third spot at 18% and falling. The Philippines and Italy round out the top five, but Italy is under 1% of global shipbuilding. The United States doesn’t make the top 15. Outside of occasional aircraft carriers, destroyers, and frigates, the United States doesn’t build ships any more.

That’s where decarbonization enters the picture. The Jones Act prohibits ferries, cruise ships, tugboats, roros, tankers, and container ships that sail between domestic US ports from being manufactured anywhere but the US. And the US doesn’t build ships. Where exactly are all of the new ships or rebuilt ships going to be built?

And, of course, there’s the question of batteries and electric drivetrains. As I was discussing recently, the US has military engineers who put electric drivetrains in nuclear submarines, but that’s about it. It’s not like electric drivetrains are horrifically difficult compared to combustion engine drivetrains, but there simply isn’t much domestic competence.

Meanwhile, in China they launched a pair of battery-electric 700-container, 10,000-ton ships for 1,000-kilometer routes on the Yangtze in 2023, part of its focus on decarbonizing all domestic maritime shipping in the next couple of decades. It’s trivial for China to source cheap batteries and build new ships around them and they are doing it.

To be clear, the transformation of maritime shipping to greater and greater electrification is going to start small and grow. Ferries and tugboats are obvious vessels for electrification. But there are a lot of them and very few organizations which can transform them in the US, never mind build new ones.

Decarbonizing inland and short sea shipping rapidly requires buying a lot of vessels from China. That’s not going to fly in the US, so it’s sailing against instead of with the tide.

Europe Is Better Off, But Not Much

Europe has its own cabotage acts, but they are nowhere near as pervasive as the Jones Act. By definition, the EU is a collection of nations with free trade, so there’s a strong argument against them. And neighboring countries have tended to have favorable cabotage allowances as well. It’s actively hard not to cross country borders in Europe, much more like crossing state boundaries in the United States. Frankly, it’s harder to cross provincial boundaries in most of Canada simply because the provinces are mostly so enormous. In Europe, some people wake up in one country, have lunch in another country and do some shopping in a third before returning home, all by car or public transit.

Italy, Germany, Finland, France, Norway, Turkey, and the Netherlands all maintain vestigial shipbuilding industries, but they add up to less than 2% of global shipbuilding and aren’t massive, scaled shipyards capable of churning out hundreds of new or retrofitted vessels. Their work forces are old and retiring. And while battery gigafactories are emerging in Europe, China’s gigafactories are churning out TWh of batteries annually now.

As an indication of how this is playing out, Maersk is buying dual-fuel ships that can burn either methanol — or biomethanol, the best of the also-ran repowering alternatives from my perspective — or standard marine bunkering fuel, diesel’s uglier maritime cousin. Is it getting them from European shipyards? No, the first one was built in South Korea.

I’m in touch with multiple European maritime industry contacts, and in 2023 was flown to Glasgow to debate maritime shipping decarbonization for a Stena Sphere shipping professionals audience. Europe’s ability to transform its fleets domestically is very low. Thankfully, its ability to buy from Asia is much less restricted, so as with the strong prevalence of Chinese-manufactured buses entering Europe, I expect a lot of Chinese-manufactured ships, along with South Korean ones, to be sailing in European coastal waters and rivers in the coming decades.

But when we consider the ships that will be delivering global trade, Europe and the United States won’t be building them any more than they do today unless they commit to massive reindustrialization of their economies. I just don’t see that happening.

What this means is that Asia has the conditions for success for electrification of shipping and will likely do it faster, Europe will lag but get there reasonably quickly with a lot of Asian-built and some domestically-built ships, and the United States, just as with rail, will be last and least to the actual decarbonization solution party.

A serious US response to decarbonizing shipping would involve eliminating the Jones Act and an industrial policy that actually built lots of new ships and battery gigafactories in the US. Only some battery factories are in plan and the current plummeting of battery prices globally is stopping many of those. I don’t see the United States getting its ducks in a row on this for at least a decade or two, if then.

This article was originally published at CleanTechnica as “Europe & USA Sailing Against Tide, Asia Sails With It In Decarbonizing Shipping.” It has been archived and lightly updated at TFIE Strategy Briefing with the current maritime-electrification and industrial-capacity framing.

When I wrote a recent assessment of Mark Carney’s Alberta pipeline deal, the cleanest reading was that Ottawa had given Alberta political option value rather than a financed pipeline. That remains the right reading, but the evidence has moved. The project is now more concrete politically because Trans Mountain has been put in the frame as the public-sector vehicle. At the same time, the commercial case has become weaker because the visible barrel denominator is smaller than the proposed pipe and the cheaper exit routes are already lining up.

The July announcement makes the public-risk question harder to treat as theoretical. The proposed west-coast pipeline would carry 1 million barrels per day, would be built by government-owned Trans Mountain in coordination with Pembina, and would be majority-owned by the federal government through Trans Mountain and Alberta through the Alberta Petroleum Marketing Commission. Pembina would hold 10% during construction, with an option for another 10% after the project enters operation, while funding details are still being negotiated. That is not a completed financing package, but it is also no longer only tone and process. Carney has not written the TMX-scale cheque. He has crossed the public-proponent line.

That matters because Alberta’s argument is still being framed as if the province has a large visible barrel problem that only a new west-coast pipe can solve. It does not. Alberta production can grow, and probably will, but the useful question is not whether oil-sands output rises. The useful question is whether the visible growth requires a new 1 million barrel per day west-coast pipeline after existing routes, Trans Mountain optimization, Enbridge optimization and southbound proposals are counted.

The Alberta Energy Regulator’s base case has total raw bitumen production rising from 3.558 million barrels per day in 2024 to 4.061 million barrels per day in 2034. That is about 503,000 barrels per day of additional raw bitumen over a decade. AER is explicit that raw bitumen is not the same thing as marketable pipeline crude: raw bitumen is extracted, viscous material that must be blended or upgraded to meet pipeline transport specifications.

The next step is the one the public argument usually skips. AER’s crude bitumen removals forecast implies that by 2034 upgraded bitumen removals rise by about 48,000 barrels per day, non-upgraded bitumen removals rise by about 329,000 barrels per day, and pentanes-plus diluent for bitumen transportation rises by about 183,000 barrels per day. Add those together and the visible oil-sands-related pipeline stream is roughly 560,000 barrels per day, but about a third of the increment is the light hydrocarbon needed to move the heavier barrel, not new bitumen production.

That 560,000 barrel per day pipeline-stream increment is the denominator. It is not small, but it is also not a million new barrels looking for a new west-coast pipe. It is a mature-asset growth case built out of optimization, incremental expansions and diluent-heavy transport volume. That is a very different commercial story from a new oil-sands boom large enough to justify another 1 million barrel per day export corridor.

The capacity comparator is just as awkward for Alberta’s claim. Trans Mountain has already launched an open season for incremental firm transportation contracts and said future projects would add about 90,000 barrels per day by early 2027 and another 210,000 barrels per day through the Mainline Optimization Project by the end of 2028, lifting total system capacity from roughly 890,000 to about 1.19 million barrels per day. That is the lower-risk west-coast option sitting directly beside the proposed new line: more flow through the existing Crown-owned pipes before a new corridor has to be justified.

The southern route is also not standing still. Enbridge has approved Mainline Optimization Phase 1, adding 150,000 barrels per day to the Mainline and 100,000 barrels per day to Flanagan South in 2027, supported by long-term take-or-pay contracts from Edmonton to Houston. Enbridge has also tested another possible 250,000 barrel per day phase. South Bow’s Prairie Connector is still a proposed project with permitting and final-investment-decision risk, but it is also a large southbound option and has been reported as having 20-year binding commitments for about 80% of proposed capacity. The contrast is not that every alternative barrel of capacity is guaranteed. It is that the alternatives are closer to existing refinery relationships, lower-risk than a new west-coast megaproject, and in some cases already supported by shippers.

This changes the meaning of Alberta’s complaint. The visible 2034 growth case has exits. A new million-barrel west-coast line therefore needs one of three things: rerouted barrels from existing pathways, a larger oil-sands growth wave than the forecast shows, or a toll and risk structure made attractive by the public balance sheet. The first is a displacement story, not a growth story. The second needs upstream FIDs and long-dated shipper commitments that are not visible. The third is the TMX lesson wearing a new hard hat.

The market side does not rescue the argument. Alberta’s crude is not generic oil flowing into a generic global demand pool. It is mostly heavy, sour, diluted bitumen that depends on complex refineries, long-lived transport-fuel demand and discounts wide enough to make the upgrading and coking hardware pay. California, one of the more natural Pacific heavy-crude markets, is losing refining capacity: the EIA says the planned Phillips 66 Wilmington and Valero Benicia closures amount to 17% of California refinery capacity and 11% of West Coast refining capacity, with replacement fuel more likely to come as refined-product imports from Asia than as new crude demand into California refineries.

China is not a simple answer either. It will keep buying crude, including heavy and sour barrels when the price and refinery slate work, but its oil demand story is changing. Heavy-truck electrification is now being pushed by policy, battery suppliers and infrastructure owners, and CATL’s partnership with Sinopec to build 10,000 battery-swap stations explicitly targets range bottlenecks for passenger vehicles and heavy-duty trucks. That does not eliminate Chinese demand for imported crude, but it weakens the diesel-growth story that helps heavy-crude refining economics. The remaining growth wedge is increasingly petrochemical feedstock, where Alberta’s diluted bitumen is not the advantaged molecule compared with lighter streams such as ethane, LPG and naphtha.

What this means is that even the 300 kbpd Mainline Optimization is looking risky given market dynamics. Increasingly, heavy crude refineries will be buying oil on spot markets and the price is going to go down faster than light crude, outside of specific events which push it the other way briefly. Albertan suppliers who are betting on hundreds of thousands of new barrels of their less valuable product finding a market are already making a questionable wager.

The original assessment was that the deal was ugly optics, not a funded pipeline. That remains true, but it is no longer sufficient. The better current framing is that the project is more politically real and less commercially necessary. Ottawa has made the public vehicle more visible, Alberta has made the political demand louder, and the production and capacity numbers have made the missing-barrel problem harder to ignore.

Carney still has a political win even if no pipeline is built. He can say Ottawa opened the door, gave Alberta a route into the Major Projects process, kept the north-coast tanker fight out of the center of the proposal, and let the commercial stack prove itself or fail. If shippers, tolls, Indigenous agreements, Pathways commitments, upstream FIDs or buyers do not materialize, Ottawa can argue that it did not block the pipeline. The market declined to build it. He’s turned Smith and Poilievre’s ammunition into duds in the lead up to the referendum on having a referendum about separation.

For Alberta, that is the uncomfortable part. The province is not short of plausible egress for the visible forecast barrels. It is asking Canada to validate optionality for a larger oil-sands future than the current production forecast shows. That may be useful politics. It may even be useful bargaining. It is not yet a market case.

My earlier conclusion survives, but the update is harsher. Alberta’s visible barrels have cheaper exits, while the proposed million-barrel west-coast line needs barrels not in the forecast, buyers not yet visible, shippers not yet signed or a public balance sheet willing to repeat the TMX lesson. Until one of those appears, the missing barrels are the story.

Vancouver has an electric fire truck. I’ve even seen it. That still sounds like a line from a pilot project brochure, but the truck is real, it is in service, and it is part of the city’s municipal fleet. I had also been looking at electric garbage trucks recently, another class of heavy urban vehicle that is moving from novelty to normal fleet asset in a growing number of cities. That led to the question that started this review. Are electric fire trucks on the same path? Are they quietly spreading while most people are not paying attention, the way electric buses, refuse trucks, delivery trucks, and port drayage tractors have moved from curiosity to procurement category?

The answer is more interesting than a simple yes or no. Electric fire trucks are no longer concept-stage technology. They are operating in real departments, on real streets, at real airports, and in real emergency-service settings. But they are not quietly prevalent either. They remain rare, expensive, customized, and dependent on one of the slowest-turnover markets in public procurement. Vancouver’s truck is not an isolated gimmick, but neither is it a sign that fire apparatus electrified while nobody was looking. The technology is ahead of the market.

The first step is to define what counts. An electric fire truck can mean a compact appliance with a 300 litre tank for narrow medieval streets, a North American pumper with a 500 gallon tank and a 1,500 gallon per minute pump, a European rescue-pumper with a 2,000 litre tank, an aerial ladder, or an airport rescue and firefighting crash truck carrying 12,000 litres of water. Those are all legitimate fire apparatus, but they are not the same technology or procurement problem. This review is not mainly about electric chief’s cars, inspection SUVs, command vehicles, ambulances, robots, or light utility vehicles unless they are doing real fire-service work. The hard question is whether the main apparatus, the large vehicles with pumps, tanks, hose beds, ladders, crew cabs, rescue equipment, and emergency-duty expectations, are becoming electric.

The comparison with electric garbage trucks is useful because refuse vehicles are one of the better heavy-vehicle electrification use cases. They run known routes. They return to the same depot. They stop and start all day. They move slowly. They idle. They burn diesel in neighbourhoods. They are loud. Their duty cycle is hard on diesel drivetrains and friendly to electric drivetrains, with regenerative braking, low-speed torque, depot charging, and less maintenance all aligned with the work. In climate, air-quality, and operating terms, they are almost too obvious.

Fire trucks share part of that logic. They live at depots. They operate in cities. They have bursts of acceleration, braking, idling, short-distance travel, and long periods at station. Diesel exhaust in fire halls is a health concern. Noise matters when firefighters are communicating on scene. Electric drive can make sense for response, and electric power take-off can reduce engine idling during pumping and equipment use. Most fire department calls are not major structure fires. In many cities, medical calls, alarms, small fires, vehicle incidents, public-assistance calls, and other non-structure-fire responses dominate call volume. For that ordinary urban duty cycle, an electric pumper can make practical sense.

Electric drivetrains are also suited to heavy urban vehicles. Instant torque helps move a loaded truck from a stop. Regenerative braking can recover energy and reduce brake wear in stop-start use. Fixed-base charging at a fire hall is easier than relying on public charging for a random heavy truck. Fire scenes are communication environments, and quieter equipment can improve working conditions. Firefighters already face smoke and other occupational exposures, so reducing diesel exhaust in apparatus bays and around vehicles is not a soft benefit. It is an occupational-health benefit.

The difference is that garbage trucks have routes, while fire trucks have uncertainty. A refuse truck can be scheduled around range, payload, weather, charging, and maintenance windows. A fire truck might respond to a medical call two kilometres away, then a kitchen fire, then a motorway crash, then a mutual-aid request, then a structure fire where it has to pump for hours, and then a windstorm response while the power is out. Most days are manageable. The problem is that fire apparatus are not purchased for most days. They are purchased for the bad day.

That is why electric fire trucks remain a more complex adoption case than electric refuse trucks, even though some of the operating physics are similar. Fire departments are conservative for good reasons. They buy mission-critical equipment with long service lives, high public visibility, and low tolerance for failure. A garbage truck breaking down creates missed collections and angry residents. A fire truck breaking down can become a public-safety event. That changes procurement culture, risk tolerance, and the pace of adoption.

The global deployment pattern shows progress, but also scale limits. The continent-level table makes the spread clearer than a long catalogue of cities. North America and Europe have the largest public counts of full-size municipal electric pumpers and ladders. Oceania and Europe have important airport deployments. Asia has a larger count of compact and community-scale vehicles, especially because of China, but those are often not equivalent to full-size urban pumpers. South America has at least one important full-size deployment. Africa did not show a public deployment in the sources reviewed. The table is not a global registry, but it is good enough to show the shape of the market: geographically widespread, operationally real, and still small.

North America’s useful example is Vancouver, partly because it started this question and partly because it is a normal city deployment rather than a showpiece. Vancouver Fire Rescue Services received a Rosenbauer RTX electric fire engine in late 2023 and moved it into regular service in 2024. It is a full-size rescue-pumper, not an electric command vehicle or small utility truck. Los Angeles and Victoria show the same Rosenbauer platform in other city contexts, while Pierce Volterra and E-One Vector deployments show that North America is not a one-manufacturer market. That matters because maturity begins when a technology is offered by multiple suppliers and purchased by multiple departments for real service.

Europe’s strongest example is Berlin. Rosenbauer reported that Berlin’s early RT handled about 1,400 missions, more than 770 operating hours, over 13,000 km, and more than 90% operation in pure-electric mode before the city added five more RTs. That is the kind of evidence that moves a vehicle from novelty toward fleet equipment. Vienna, Basel, Hamburg, Zurich, and several German industrial and institutional deployments add breadth, but Berlin is the anchor because it combines real operating history with repeat procurement.

Asia’s most important lesson is category discipline. China’s Beijing Tongzhou district received 21 small electric fire trucks for rural and township use in 2023, according to Beijing municipal media. That is a meaningful deployment, and it is larger than most Western city examples by unit count, but the vehicles are smaller community fire apparatus, not direct equivalents of North American pumpers, European rescue-pumpers, or ARFF crash trucks. Japan’s Tokyo Fire Department deployment and Singapore’s electric pump ladder show another part of the Asian picture, but China’s smaller-vehicle ecosystem is the reminder that “electric fire truck” can mean different things in different operational systems.

Oceania’s useful example is Christchurch Airport in New Zealand, which took possession of a Rosenbauer RT as the country’s first electric fire truck. Airports are a distinct niche, but they matter. Airport fire vehicles operate from fixed bases, serve defined response zones, and are procured by organizations that can plan charging infrastructure as part of site operations. Australia adds another layer, with ACT Fire & Rescue’s electric pumper in Canberra and Oshkosh Striker Volterra hybrid-electric ARFF vehicles for Western Sydney International Airport.

South America’s clear example is Santiago, Chile, where the Santiago Fire Department received a Rosenbauer RTX through Bomba Arturo Prat in 2025. SQM Lithium and local reporting described it as the first electric fire truck in Latin America. That matters symbolically and practically, because it demonstrates that the technology is not confined to Europe and North America. But it is still a single-unit regional milestone. It proves the category can travel. It does not prove regional market maturity.

The absence of a public African deployment in the table is not proof that none exists anywhere on the continent. It is a statement about what this review found in public sources. It is also a useful reminder that electric fire apparatus adoption depends on municipal capital budgets, grid infrastructure, fire-service procurement practices, manufacturer presence, and grant or climate-funding support. The early market is not spreading evenly. It is appearing first where city budgets, manufacturer sales efforts, climate policy, and fire-service experimentation overlap.

The denominator changes the interpretation. A few dozen or even a hundred electric fire trucks can sound impressive until they are compared with the number of fire apparatus in the world. CTIF’s 2025 World Fire Statistics report provides one of the best public baselines. Across 65 countries in its 2023 apparatus table, CTIF reported 159,921 fire stations, 214,051 fire engines, and 19,423 fire ladders. Engines plus ladders add to 233,474 vehicles in that dataset alone. That does not represent the entire world, and it does not include every tanker, brush truck, rescue truck, support truck, industrial vehicle, airport vehicle, or smaller specialty unit.

The United States shows why the denominator is hard. NFPA’s U.S. fire department profile reported about 68,800 pumpers over 1,000 gallons per minute, 7,400 aerial apparatus, and 76,300 other suppression vehicles for 2018 to 2020. That “other suppression vehicles” category includes a lot of real firefighting capacity, including smaller pumpers, tankers, brush vehicles, and similar units. A narrow engine-and-ladder count misses much of the operational fleet. China shows the other side of the problem. China’s National Fire and Rescue Administration reported 92,677 vehicles at the end of 2023, but that figure includes emergency support, duty, technical, and other vehicles, not a clean pumper-and-ladder count.

The safest article-level denominator is that the world has at least several hundred thousand fire-service vehicles, with a public lower bound of roughly 233,000 engines and ladders in the CTIF dataset alone. The broader operational fire-vehicle fleet is larger. If publicly visible electric fire apparatus number roughly 80 to 120 globally, including compact Chinese vehicles and airport crash trucks, they represent about 0.03% to 0.05% of CTIF’s engines-and-ladders lower-bound denominator. If the comparison is limited to full-size municipal electric pumpers, rescue-pumpers, and ladders, the share is lower. Electric fire trucks are visible because they are unusual, not because they are numerous.

Turnover is the other constraint. Fire trucks last a long time. North American practice is often summarized around 15 years of frontline service for an engine, followed by 5 to 10 years in reserve. NFPA guidance has long been interpreted around 15 years for frontline apparatus and no more than about 25 years in emergency service, although recent fire-apparatus trade discussions note that the service-life language sits in annex guidance rather than as a simple binding rule. In practice, a high-call urban department may want to replace apparatus sooner, while a low-call rural or volunteer department may keep equipment much longer because the budget does not exist for faster replacement.

The math is simple and important. A 15-year frontline replacement cycle implies a theoretical turnover rate of 6.7% per year. A 20-year total-service cycle implies 5% per year. A 25-year cycle implies 4% per year. Those are theoretical values before procurement delays, budget deferrals, supply-chain backlogs, and reserve use. Even if every new fire truck purchased tomorrow were electric, the global installed base would take one to two decades to change in a visible way. In the real world, only a small fraction of new purchases are electric, so fleet penetration will be slow.

That slow turnover separates fire trucks from buses in particular. A large transit agency can place an order for 50, 100, or 300 buses, and China has already shown what happens when electric buses become industrialized. The International Energy Agency reported more than 70,000 electric buses sold globally in 2024. That is a one-year sales figure larger than the entire visible global electric fire apparatus population by about three orders of magnitude. A fire department may replace one engine, then a ladder five years later, then another pumper a few years after that. It is not the same fleet dynamic.

Diesel fire trucks are already expensive, which matters when evaluating the electric premium. Modern North American pumpers are often in the $750,000 to $1.3 million range, depending on chassis, pump, tank, equipment, rescue body, electronics, warranty, and local specifications. Highly specified rescue-pumpers can exceed that. Aerial ladders and platforms commonly sit around $1.4 million to $2 million or more. ARFF airport crash trucks are specialized multi-million-dollar equipment in many cases. Reuters reported in 2025 that fire truck prices had roughly doubled over the previous decade, with some ladder trucks reaching $2 million and delivery backlogs stretching for years.

Electric pumpers cost more. The current practical range for electric municipal pumpers appears to be about $1.4 million to $2.1 million in many North American examples, with project costs sometimes rising higher when charging equipment, utility work, station upgrades, and first-of-kind expenses are included. Vancouver’s Rosenbauer RTX was reported around C$1.8 million. Denton’s Pierce Volterra was reported around $1.8 million, about $600,000 more than diesel. Redmond, Washington’s electric pumper project was reported around $2.4 million including charging and related costs, compared with around $1 million for a traditional diesel engine, although grants and contributions reduced the city’s net cost.

Funding is usually a stack, not a single clean program. There is not yet a universal “electric fire truck grant” that makes this procurement simple. British Columbia provides a clean Canadian example. The province’s CleanBC Commercial Vehicle Pilots program has supported zero-emission commercial vehicle deployment and charging, with local governments and public entities eligible. Victoria’s electric fire engine was listed as a CleanBC-funded project, including the replacement of a diesel fire truck with an all-electric fire engine and a 25 kW charger, with provincial funding of about C$577,000.

Redmond, Washington shows the more complex U.S. version. The city reported an electric pumper and charging project with gross costs around $2.4 million, compared with about $1 million for a traditional diesel engine, but a city net cost of only $264,600 after grants and contributions. The funding stack included Washington Department of Ecology Volkswagen settlement funding, federal Housing and Urban Development money, utility support, and contributions from Amazon, Microsoft, and others. That example shows how an electric fire truck can be financially possible for a city without the city absorbing the whole premium. It also shows why the market is still early. Mature vehicle categories do not need bespoke funding puzzles for each purchase.

Federal fire grants can help, but they are not electric-specific in the way many people might assume. FEMA’s Assistance to Firefighters Grants are designed to help departments meet firefighting and emergency-response needs, including apparatus in some cases, but they are not a dedicated electric fire truck program. A department seeking an electric pumper may be combining a normal apparatus grant logic with climate, air-quality, or clean-transportation funds. That is different from a market where the electric option has become the standard purchase.

The hard operating cases remain hard. A structure fire with hours of pumping is different from a medical response. A major disaster is different from a normal Tuesday. Mutual aid may take a truck far from its station. Wildfire, flood, earthquake, windstorm, and extended outage events create edge cases that municipal procurement cannot ignore. Fire stations themselves need power resilience, and a city that wants electric emergency vehicles also has to think about chargers, backup power, microgrids, generators, and procedures for operating when the grid is stressed or unavailable.

That is why range extenders are common and why they should not be treated as cheating. Many electric fire trucks are battery-electric first, with an onboard diesel or gasoline generator as emergency insurance. Critics can point at the generator and say the truck is not really electric. That misses the nature of emergency infrastructure. Hospitals are grid-powered and still have backup generators. That does not make them diesel hospitals. It makes them critical facilities with backup systems. Fire trucks are similar. A range extender does not mean the electric drivetrain is fake. It means the manufacturer and department are acknowledging that emergency apparatus must cover edge cases.

The same caveat applies to airport fire trucks. Some of the ARFF vehicles in the table are plug-in hybrid-electric or range-extended rather than pure battery-electric. That should not be blurred. Oshkosh Striker Volterra deployments, for example, are part of the electrification story, but they are not identical to a battery-electric municipal pumper running most calls from a city station. Airport crash trucks are huge, specialized vehicles with demanding readiness requirements, and the hybrid-electric pathway is a bridge into electrification for a conservative niche. The distinction matters because counting all electric and hybrid-electric fire apparatus together can overstate battery-electric maturity.

The relevant question is not whether a range extender exists. The relevant question is how often it runs. If a truck operates 90% to 98% electric in real service, the fuel, emissions, noise, and maintenance implications are different from a truck that leans on the generator often. Berlin’s reported more than 90% pure-electric operation for its early Rosenbauer RT is meaningful. Reports from North American Pierce Volterra deployments with limited diesel-generator use are meaningful. This is the kind of field data that separates serious technology from press-release technology.

The field evidence is now good enough to say that electric fire trucks can work. Berlin’s operating history and repeat procurement are important. Portland’s high call volume matters. Gilbert’s reported call experience matters. Vancouver and Victoria matter because they are not just demonstration cities, they are operational Canadian deployments. Cary’s report of pumping for more than three hours at a structure fire matters because pumping is one of the core concerns people raise. Canberra’s ACT Fire & Rescue electric pumper battery issue and Charlotte’s warranty-related repair case also matter, because early vehicles teach departments, manufacturers, mechanics, electricians, utilities, and procurement teams what they did not know.

This is where the word “boring” becomes useful. Electric fire trucks have proven that they can be exciting. That is not the maturity threshold. The maturity threshold is when they become boring fleet assets. Boring means the mechanics know them. Boring means replacement parts arrive. Boring means firefighters trust them. Boring means the charger works. Boring means the city does not need a special press conference. Boring means the truck is selected because it fits the duty cycle and the replacement plan, not because it is a first.

The emissions case should also be kept in proportion. Fire trucks are not buses, garbage trucks, or drayage tractors in annual kilometres travelled. A single electric fire engine will not usually displace as much diesel as a high-mileage transit bus, a refuse truck grinding through dense neighbourhood routes, or a port tractor shuttling containers all day. The value is still real, especially for diesel exhaust in fire halls, idling, local air quality, and noise. But electric fire trucks are less about the largest near-term emissions wedge and more about expanding the operational boundary of electrification into equipment that people expect to work under pressure.

Compared with buses, electric fire trucks are early. Electric buses are a mature scaled category, with the International Energy Agency reporting more than 70,000 electric buses sold globally in 2024. Electric refuse trucks are not as mature as buses, but they are commercializing because the duty cycle is strong. Electric drayage trucks are also moving into early commercial scale, driven by port air-quality rules, fixed routes, depot and terminal charging, and high diesel fuel exposure in populated freight corridors. Electric fire trucks sit behind those categories because the market is smaller, the products are more customized, the vehicles last longer, the duty cycle is less predictable, and failure tolerance is lower.

A practical maturity ranking would put electric buses at scaled maturity, electric refuse trucks in commercial growth, electric drayage trucks in early commercial scale, and electric fire trucks in early commercial deployment. True maturity for fire trucks will have clear signs. Cities will buy their second, third, and fourth electric engines without each one being announced as the first in the region. Electric pumpers will appear in ordinary replacement schedules. Fire halls will be designed or renovated with charging as standard infrastructure. Mechanics will be trained. Range extenders will be used rarely in urban duty rather than treated as operationally central. Used electric fire apparatus will eventually appear in secondary markets. Insurance, standards, maintenance, and training will settle.

The real milestone will not be another “first electric fire truck” headline. The real milestone will be when a city replaces a diesel pumper with an electric one because that is now the obvious choice for that station, when the charger is just part of the fire hall, when the firefighters are not surprised by the drivetrain, when the mechanics are not waiting on unusual parts, and when nobody writes an article about it because it is just another truck in the bay. Electric fire trucks are not there yet. They are no longer strange. That is usually the interesting middle of a heavy-vehicle transition.

This article was originally published at CleanTechnica as “Electric Fire Trucks Are Spreading, But They Lag Buses, Garbage Trucks, & Drayage Fleets.” It has been archived and lightly updated at TFIE Strategy Briefing with the current municipal-fleet and heavy-duty electrification framing.

The electric garbage truck is not the poster child for vehicle electrification. It does not have the consumer glamour of an electric pickup, the political visibility of an electric bus, or the freight-sector drama of battery-electric and hydrogen tractor-trailers fighting for long-haul mindshare (batteries for the win, as usual). It is a boxy, heavy municipal workhorse that blocks the lane, lifts bins, crushes waste, leaks if maintenance is poor, and wakes people up before breakfast. That is why it matters. Some of the best electrification opportunities are not glamorous. They are practical machines doing predictable work, day after day, from fixed depots, on fixed routes, with high fuel burn and high local exposure.

Most residents know the diesel version by sound before sight. The truck grinds down the street, stops every few meters, idles while bins are lifted, brakes, accelerates, and repeats the cycle hundreds or thousands of times per shift. The packer body cycles. The air brakes sigh. The engine works hard at low speed. Collection workers spend much of the day close to exhaust, noise, and vibration. In dense urban neighborhoods, apartment courtyards, alleys, school zones, and early-morning routes, the truck is not an abstract source of emissions. It is a machine operating a few meters from people.

The electric version does the same job. It still has to lift bins, compact loads, finish routes, and come back to the yard. It does not ask residents to change their behavior. It does not require a household to buy anything. It does not depend on a national public fast-charging network. The fleet case is not built on lifestyle branding. It is built on fit.

The vehicle base is large, although fuzzy. Energy Vision has used an estimate of about 180,000 refuse trucks in daily service in the United States. A National Renewable Energy Laboratory report used a similar number, saying roughly 90% of about 180,000 U.S. refuse trucks were diesel-powered. That is a useful anchor. The U.S. refuse and recycling collection fleet is larger than many national bus fleets, and most of it still burns diesel or natural gas.

North America is larger than the U.S. figure alone. Canada likely adds several thousand to low tens of thousands of refuse and recycling collection vehicles, depending on what is counted. Mexico adds more scale again. INEGI, Mexico’s national statistics agency, tracks municipal solid-waste collection vehicles through its municipal government census, including the total number of vehicles operating for public urban solid-waste collection. A reasonable working estimate for Mexico is 25,000 to 40,000 collection vehicles, although the category includes a broader mix than the full-sized compactor trucks common in U.S. and Canadian comparisons. Rear loaders, dump trucks, smaller municipal vehicles, pickup-style collection vehicles, and other local collection equipment may all be in the mix.

The global vehicle base is harder to pin down. There is no clean worldwide registry of garbage trucks. Some countries count refuse collection vehicles. Some count sanitation trucks. Some include sweepers, compactors, vacuum trucks, hook-lift trucks, transfer trucks, and small urban collection vehicles. For article purposes, the safe global estimate is high hundreds of thousands to low millions of vehicles, depending on definition. If limited to full-sized Western-style compactor trucks, the number is lower. If broader sanitation vehicles are included, especially in China and other Asian markets, the number rises.

That scale matters because the current electric share remains small. A 150-truck order by Republic Services is meaningful in North American electric refuse truck history, but it is only about 0.08% of the U.S. refuse truck stock if the denominator is 180,000. Even 1,000 electric refuse trucks in North America would be less than 0.5% of a 220,000 to 260,000 vehicle regional stock. Against a global fleet somewhere between 600,000 and 1.5 million, the percentage is smaller again. The stock transition is small. The procurement transition is real.

Stock share always lags procurement share. If a refuse truck lasts 8 to 12 years, a city can electrify a large share of new purchases for several years before the total fleet looks electric. If 10% of annual replacements are electric, the stock moves slowly. If 50% of annual replacements are electric, the stock still takes most of a decade to turn over. That is why early signals matter. The important questions are whether pilots become repeat purchases, whether repeat purchases become route-class deployments, whether route-class deployments become contract requirements, and whether large haulers start treating electric refuse trucks as part of standard fleet planning.

The fit begins with the collection pattern. A long-haul tractor may travel 800 to 1,000 kilometers in a demanding day, often across routes where charging depends on infrastructure outside the carrier’s depot. A refuse truck normally works a local territory. Its energy demand is high for the distance because the truck is heavy, stops constantly, and powers a working body, but the route is known. The vehicle starts at the depot, works a district, and returns to the depot. The fleet operator controls the yard, parking location, maintenance shop, charging schedule, dispatch plan, and vehicle assignment.

The workload is better measured in stops and lift cycles than in kilometers. A truck that travels 80 kilometers in a day but stops 800 times has done much more work than the odometer suggests. It has accelerated a heavy vehicle hundreds of times, braked hundreds of times, lifted containers, compacted wet and dry material, crept through narrow streets, and often idled or cycled equipment beside homes and shops. That is why refuse trucks can burn a lot of fuel despite short routes. Distance understates the work.

That stop-start pattern suits electric drivetrains. A highway truck spends long stretches at steady speed, which is efficient for diesel and gives fewer regenerative braking opportunities. A refuse truck accelerates, brakes, stops, lifts, compacts, and repeats. Regenerative braking does not make energy free, but it recovers part of the energy that a diesel truck sheds as heat through brakes. It reduces brake wear on vehicles that brake thousands of times per week. The same logic helped electric buses make sense early. Urban duty cycles are hard on combustion engines and brakes, but they give electric drivetrains repeated opportunities to recover energy.

The vehicle is not just a drivetrain. A refuse collection vehicle is a mobile industrial machine. It may have an automated side loader, a rear loader, a front loader, hydraulic arms, compaction equipment, cameras, safety systems, and body controls. Electrification has to power both motion and work. That makes refuse trucks more complex than parcel vans. The chassis maker, body builder, battery supplier, charger provider, fleet manager, utility, maintenance team, and drivers all matter. The operational win comes when the whole system works together, not when an electric chassis is treated as a plug-in replacement for a diesel truck on any route.

Local exposure strengthens the case. A refuse truck works where people live. It does not cruise past once on a highway. It stops beside homes, schools, sidewalks, courtyards, and shops. Removing tailpipe exhaust from that pattern has local value even before climate benefits are counted. The same is true of noise. Electric refuse trucks do not make waste collection silent, because bins, compactors, reversing alerts, brakes, and workers still make sound. But they remove the diesel engine as the dominant noise source.

The adoption pattern is easier to see when grouped by maturity rather than municipality. The first stage is demonstration. That is one truck, one route, often one grant, and a lot of attention from the fleet manager. New York’s Department of Sanitation tested a Mack LR Electric. Miami-Dade bought an electric refuse vehicle. Sacramento added an electric waste collection truck. Helsinki tested an all-electric refuse truck. These trials matter because they move the technology from brochure to route sheet. They expose range, charging, payload, driver acceptance, noise, and maintenance issues under real conditions.

The second stage is early fleet deployment, usually 2 to 10 trucks in daily service. Jersey City took five BYD battery-electric refuse trucks. Cambridge in Massachusetts put a Mack LR Electric into operation and had funding for more. San Pablo in California put five McNeilus Volterra electric refuse trucks into residential service with Republic Services. Kingston in Ontario ordered two Mack LR Electric refuse trucks. Emterra launched eight Mack LR Electric trucks in British Columbia’s Comox Valley. These are not massive numbers, but they are no longer single-vehicle theatre. A fleet of five to eight trucks forces a depot to deal with charging, route assignment, redundancy, maintenance, and dispatch.

The third stage is contract-scale deployment. This is where the story becomes more important. Westminster in London moved to 45 electric refuse trucks with Veolia. Manchester and Biffa put 27 electric refuse vehicles into service, replacing about half the earlier diesel fleet for that work. Singapore’s ALBA W&H Smart City moved into electric waste and recyclables collection vehicles. WM New Zealand has gone well beyond a symbolic truck, with more than 50 fully electric heavy trucks reported and millions of electric truck kilometers accumulated. These are service-system deployments, not isolated trials.

The fourth stage is strategic transition. This is when major haulers and municipal systems stop treating electric refuse trucks as a novelty and start putting them into normal fleet planning. Republic Services ordered 50 McNeilus Volterra electric trucks in 2023 and another 100 in 2024. Renewi, PreZero, Verdis, HVC, Biffa, Veolia, and other operators have moved into repeat procurement or larger deployments in Europe. China appears to be operating in a different volume category, although the data is reported in broader sanitation-vehicle terms. At this stage, the issue is no longer whether one electric truck can complete one route. The issue is how fast suitable route classes can be converted.

Europe is the most visible market outside China because city announcements, OEM releases, and municipal procurement are easier to find and compare. The United Kingdom has major examples in Westminster and Manchester, with other deployments and trials across councils such as Nottingham, Leeds, Salford, and the Cambridge area. Continental Europe shows the same pattern across the Netherlands, Germany, Spain, Scandinavia, Switzerland, and Austria. The names change by country, from Veolia and Biffa to HVC, Renewi, PreZero, Verdis, and municipal operators, but the pattern is consistent. Electric refuse trucks are moving from trials into city service contracts and fleet replacement plans.

North America is mixed, but moving. The United States has many pilots and early fleets, yet Republic Services’ 150-truck orderbook and full local electric collection fleets in places such as Louisville and San Pablo show movement beyond demonstration. Canada has Emterra in the Comox Valley, Kingston in Ontario, pilots in Peel Region, Environmental 360 Solutions, and electric refuse activity in British Columbia. Mexico is harder to assess for electrification because the public data is more focused on waste collection vehicles and service coverage than electric procurement, but Mexico should be in the denominator. Excluding it makes North America look smaller and wealthier than it is.

China is the largest signal and the messiest comparison. Chinese sources often discuss new-energy sanitation vehicles, not only full-sized garbage compactor trucks. That category can include sweepers, washing trucks, mini-compactors, garbage transfer trucks, and other municipal cleaning vehicles. One Chinese market summary reported about 85,000 municipal sanitation vehicles sold in the first half of 2025, including about 18,700 new-energy vehicles. That is roughly 22% new-energy penetration for that reported half-year category. Even if only part of that category maps to Western refuse trucks, the volume is large. It would be a mistake to relegate China to a footnote because the definitions are untidy.

China probably has roughly 450,000–570,000 urban and county sanitation vehicles/equipment in service. Of those, perhaps 60,000–110,000 are garbage compactor trucks of all sizes, and perhaps 35,000–90,000 are heavy compactor trucks above about 14 tons GVW. The battery-electric heavy compactor truck stock is much smaller but no longer trivial: probably a few thousand vehicles, likely around 2,000–6,000 active units, with an upper bound near 8,000. That is still a small share of China’s heavy compactor fleet, but it is much larger than the documented electric refuse truck fleets in Europe and North America combined.

The safer conclusion is not that China’s numbers can be compared one-to-one with the U.S. 180,000 refuse-truck denominator. They cannot. The better conclusion is that China has treated municipal sanitation vehicles as part of the same industrial electrification wave that transformed buses, delivery vehicles, taxis, two-wheelers, port equipment, and urban logistics. Western readers often miss this because the categories differ, the sources are less visible, and the vehicles do not show up in the same English-language media streams. If one is asking where electric sanitation vehicles are likely being deployed at the greatest volume, China is the obvious candidate.

Asia-Pacific outside China is worth attention as well. Singapore’s ALBA deployment shows that a dense city-state with structured waste contracts and depot operations can move quickly. Australia has electric waste truck trials and deployments in Adelaide, Melbourne-area councils, and other local government settings. New Zealand is one of the clearest examples because WM New Zealand has accumulated real operating experience across a fleet, not just a one-truck trial. Latin America, the Middle East, and Africa are earlier, with first-of-kind examples in Chile, Abu Dhabi, and Rabat. These are early signals, but they show geographic spread.

The reason this transition is flying under the radar is not that the evidence is weak. It is that the evidence is fragmented. Garbage trucks are municipal infrastructure, not consumer products. The vehicles are bought through tenders, grants, service contracts, fleet replacement plans, and depot upgrade programs. The people making the decisions are fleet managers, public works directors, procurement officers, waste contractors, and utility service planners. They are not selling identity. They are trying to get Tuesday’s route completed.

The language also hides the trend. Depending on the country and source, the same broad vehicle class is called a garbage truck, refuse collection vehicle, RCV, waste truck, sanitation truck, solid waste truck, municipal service vehicle, vocational truck, low-cab-forward Class 8 chassis, or compacting collection vehicle. In China, the relevant category may be new-energy sanitation vehicles. In Europe, the announcement may be by the body builder, chassis manufacturer, hauler, council, or charging provider. In North America, the same vehicle may be covered by a local newspaper, an OEM press release, or a grant program. Search for only one term and most of the market disappears.

Electric buses also took much of the public-sector EV spotlight. Buses carry voters. They have route numbers, public branding, riders, unionized operators, and transit agencies with public boards. Electric bus procurement became a visible symbol of municipal and regional climate action. Garbage trucks are seen by everyone but loved by almost no one. Residents notice them most when they are loud, late, leaking, or blocking a street. That makes the public case harder, even though the service case can be just as strong.

CNG and renewable natural gas occupied the green garbage truck lane for years, especially in North America. Many cities and haulers moved refuse fleets from diesel to compressed natural gas because CNG reduced some pollutants compared with older diesel engines, lowered noise, and provided a cleaner-fleet narrative. Some fleets used landfill gas or digester gas pathways to claim renewable natural gas. That history was not irrational. Older diesel refuse trucks were loud and dirty, and CNG offered a path to lower some local pollutants. But battery-electric trucks change the endpoint. They remove tailpipe exhaust on the route, reduce curbside noise, and reduce exposure to diesel and gas price volatility.

The municipal case for electric garbage trucks should not start with climate branding. That may work for progressive audiences, but it can sort the room before the operational argument is heard. The stronger frame is practical stewardship of a necessary public service. Every city has to collect waste. Every city has to replace trucks. Every city has routes where diesel trucks spend hours in neighborhoods, near children, seniors, workers, apartment residents, and pedestrians. If a quieter, cleaner truck can perform the same route and return to the same depot for charging, that is not a symbolic act. It is a better tool for a job the city already has.

That frame can work across political audiences. Progressive voters hear cleaner air, less neighborhood pollution, lower emissions, and protection of workers. Conservative voters can hear disciplined fleet modernization, practical local stewardship, respect for municipal crews, and reduced exposure to diesel price swings. A city does not have to lead with net zero, climate emergency, or green leadership to make the case. It can lead with quieter mornings, less exhaust on residential streets, better working conditions, and a core service delivered with modern equipment.

The best municipal message is simple. Waste trucks are among the hardest-working vehicles in the city. They stop at every home, work predictable local routes, and return to the same depot every day. That makes suitable routes strong candidates for electric trucks. As older diesel trucks reach replacement age, the city can move the right routes to quieter, cleaner vehicles, test performance, and scale where the numbers work. Residents get quieter mornings and less exhaust. Crews get better working conditions. The city gets a modern fleet for an essential service and less exposure to fuel-price volatility.

The economics are not magic. Electric refuse trucks cost more upfront than diesel trucks in most current procurements. Charging infrastructure is not free. Depot electrical upgrades can be slow and expensive. Transformers, switchgear, trenching, charger placement, cable management, backup planning, and software integration all matter. A fleet that buys trucks without solving depot power has not bought a solution. It has bought assets that may sit constrained by electrical infrastructure.

The operating savings can still be material. Diesel refuse trucks consume a lot of fuel per kilometer because of stop-start operation, idling, compaction loads, and low-speed work. Electricity is often cheaper and less volatile per unit of delivered work, especially for planned depot charging. Electric drivetrains have fewer moving parts than diesel engines and transmissions. Regenerative braking reduces brake wear. Electric operation reduces noise complaints and improves worker conditions. In some jurisdictions, quieter operation may allow more flexible collection windows, although that depends on local rules and labor agreements.

The business case should not be stated as “electric is always cheaper everywhere.” That will fail under scrutiny. The better statement is that the right refuse routes should be electrified first, and this segment has a lot of right routes. Dense residential routes, short daily distances, single-shift operations, return-to-base schedules, predictable payloads, and high stop frequency are the first tier. Rural long-distance routes, heavy transfer work, double-shift trucks, steep terrain, cold-weather extremes, or routes with uncertain charging windows may come later or require larger batteries, more chargers, route redesign, or interim combustion vehicles.

Route-level math is the center of the operational case. Brochure range is not route range. A truck that can travel a stated number of kilometers under one test cycle may perform differently when it is lifting bins every few meters, compacting wet waste, climbing hills, running heat in winter, or using air conditioning in summer. Payload matters because batteries add weight and waste density varies. Stops per kilometer matter. Grade matters. Temperature matters. The body system matters. The driver matters. A city that ignores these variables will learn from failure instead of planning from evidence.

Charging is the other half of the system. Refuse fleets are good candidates for depot charging because they return to base, but depot charging is still infrastructure. A yard with 30 diesel trucks can refuel them quickly if it has a fuel island. A yard with 30 electric trucks needs enough chargers, enough power, enough space, and enough scheduling discipline. The utility may need months or years to deliver upgrades if the depot is constrained. A city that wants 20 electric refuse trucks in 2028 may need to start the utility conversation in 2026.

Maintenance teams need to be part of the transition from the start. Electric trucks reduce some maintenance burdens, but they add new ones. High-voltage systems require training. Diagnostics change. Body integration matters. Mechanics need safe work procedures, tools, and OEM support. Drivers need training on regenerative braking, efficient operation, charging checks, and route feedback. Dispatchers need to know which routes fit which vehicles. Procurement staff need to understand that the chassis, body, battery, charger, depot, software, and utility connection are one system.

Refuse trucks may beat many other heavy-duty segments to electrification because the infrastructure problem is bounded. Long-haul trucking needs corridor charging, high-power stations, driver scheduling, land, grid upgrades, and coordination across shippers, carriers, truck stops, utilities, and regulators. Agricultural equipment can face seasonal peaks, long workdays, field charging, and remote sites. Construction equipment moves among job sites and can have irregular duty cycles. Intercity coaches and regional freight need networks. Refuse collection is local. The yard is known. The collection pattern is known. The vehicle returns home. That gives the fleet manager more control.

This places refuse trucks in the same early-electrification family as transit buses, school buses, delivery vans, terminal tractors, port drayage trucks in defined corridors, and yard trucks. These are not the easiest vehicles in every respect, but they share bounded duty cycles and high local benefits. In many cases, they also have public or corporate buyers that can plan infrastructure. The first wave of heavy-duty electrification was never going to be every vehicle everywhere. It was going to be the niches where batteries match the work. Refuse trucks are one of those niches.

Municipalities should start with the route database, not the press release. The first task is to sort the route book into easy, medium, and hard candidates using distance, stops, grade, payload, shift length, depot dwell, and backup requirements. The first 10% of routes should be the ones most likely to succeed. The utility conversation should begin before the truck tender is written. The truck, body, charger, software, and service support should be procured as a system. Crews should be trained before launch. Energy use per route, route completion, charge time, maintenance, driver acceptance, noise, and resident response should be measured. Replacement cycles should do much of the work, unless there is a strong health or financial reason to retire assets early.

The mistakes are clear as well. Do not buy one electric truck, put it on the longest, hilliest, most demanding route in winter, and declare the technology failed. Do not issue a 100% electrification promise without a transformer, charger, route, and replacement-cycle plan. Do not treat the charger as an accessory. Do not exclude drivers and mechanics from pilot design. Do not compare electric and diesel trucks on purchase price alone. Do not assume that a successful pilot in one city maps to every route in another. Do not take China’s broad sanitation-vehicle statistics and present them as identical to North American refuse compactor counts.

While battery electric refuse trucks are growing globally, hydrogen refuse trucks barely saw trials. The record is not encouraging. Arnhem produced one clear failed trial, Herten showed reliability problems, Bielefeld’s seven trucks were sidelined by refueling infrastructure failure, Glasgow cancelled a 19-truck procurement before deployment, and Hyzon’s North American refuse-truck push ran into company liquidation just after “successful” trials and early orders. The pattern is not that every hydrogen garbage truck breaks. The pattern is that the truck, fuel, depot, maintenance, supplier, and business case have to work as one system, and that system keeps proving fragile. The lesson for municipalities is that there is no real choice between hydrogen and batteries: batteries have won globally and are scaling. Don’t waste time assessing hydrogen as an alternative when the test has already been performed.

The quiet revolution is quiet because the trucks are quiet, the buyers are municipal, the evidence is local, and the language is fragmented. It is also quiet because this is not a story about novelty. It is a story about ordinary public services getting better equipment. The global stock is still mostly diesel, CNG, or other combustion. The denominator remains large. But the direction is visible. Single-truck demonstrations have become early fleets. Early fleets have become contract-scale deployments. Contract-scale deployments are becoming strategic procurement for some operators. China appears to be operating at larger sanitation-vehicle volumes than Western discussions often recognize.

The diesel garbage truck announces itself with noise, fumes, vibration, and heat. The electric garbage truck announces itself less. It still does the work. It still needs a crew, a route, a depot, a charger, a maintenance plan, and a budget. It will not solve all municipal fleet emissions, and it will not electrify every route on the same schedule. But it is one of the clearest places where heavy-duty electrification matches the task. The transition will arrive one depot, one route, and one replacement cycle at a time, until residents start noticing that the loudest truck on the block has become a lot easier to ignore. The global evidence makes it clear that municipalities should move directly to early fleets, skipping the demonstration phase. Battery electric heavy compactor garbage trucks are proven technology, so trialing just wastes time and money.

Grid storage is no longer a speculative side issue in the energy transition. Batteries are scaling fast enough to reshape system planning, pumped hydro remains the durable bulk-storage anchor, and the long-duration storage category increasingly has to be separated into technologies with operating evidence and technologies still relying on claims that have not yet become repeatable fleets.

The harder question is not whether a mostly electrified world needs storage. Of course it does. The harder question is how much dedicated electrical storage is actually required once transmission, demand flexibility, seasonal thermal storage, strategic reserve and better system design are counted before the grid is forced to buy more batteries, more pumped hydro or another round of speculative storage.

This article is an update of my now years old 2100 base-case scenario, not a prediction. It tests what appears plausible if electrification continues, batteries keep scaling, pumped hydro remains the mature bulk-storage anchor, and flexibility, thermal storage, transmission and strategic reserve do their share of the work. I don’t claim to be right, I just claim to be less wrong than most, and being less wrong requires updating when deployment, costs and system thinking change.

In my 2021 assessment of grid storage winners, the logic was pumped hydro first, lithium-ion for shorter-duration and ancillary-service work, and redox flow as the dark horse likely to gain share as storage duration lengthened. The projection that followed ran only to 2060, was framed mostly in GW rather than a full GW/TWh/duration stack, and used a rough read of Jacobson’s storage table to infer a much larger global energy requirement, around 210 TWh. Five years later, the parts that survived are the need for multiple storage classes, pumped hydro’s bulk-duration role, and the importance of not treating storage as a prerequisite for early renewable deployment. The parts that changed are the weights and the boundary: batteries have scaled faster and fallen further in cost than I expected, longer-duration BESS is now appearing in formal procurement, redox flow has not matched battery manufacturing scale or bankable deployment, and the model now separates dedicated electrical storage from V2X, demand flexibility, thermal storage, transmission and strategic reserve. The result is less flow, much more BESS, pumped hydro still large, Other electrical LDES still capped, and a lower dedicated-storage endpoint because the current model is not asking storage to solve every reliability problem.

The battery evidence is the first reason. The International Energy Agency reports that 108 GW of new battery storage was deployed globally in 2025, 40% more than in 2024, with installed capacity roughly eleven times higher than in 2021. That is not a demonstration market or a pre-commercial wave. It is infrastructure scaling at industrial speed, and any serious 2100 grid storage scenario has to treat batteries as the central manufactured storage technology.

The cost story pushes in the same direction. BloombergNEF’s 2025 battery price survey found stationary storage battery packs at $70/kWh, down 45% from 2024. Full battery systems still have inverters, containers, grid connections, civil works, fire systems and permitting to pay for, but the heart of stationary storage is now cheap enough to keep moving into duration bands that other technologies expected to own.

The old argument that batteries were for two and four hours while a broad long-duration storage category would own the rest is looking increasingly threadbare. The UK’s first LDES cap-and-floor minded-to portfolio includes multiple Li-ion BESS projects in the 8 to 18 hour range, which makes longer-duration BESS a formal procurement category rather than a speculative extension of today’s short-duration market. China sharpens the point: Rho Motion reported China’s BESS fleet at 106.9 GW / 240.3 GWh by May 2025, already larger in power-capacity terms than China’s reported end-2024 pumped-hydro fleet. The average duration is still only a bit over two hours, so this is not proof that 8 to 10 hour batteries have become the global norm, but it is a strong current signal that batteries are the fastest-scaling storage class.

Pumped hydro still matters enormously, and the projection preserves that. Pumped hydro is the gravity storage technology that actually works at grid scale, with mature equipment, long asset life and enough round-trip efficiency to be useful. China is the counterweight to any casual dismissal of pumped hydro. Reuters reported that China reached 58.69 GW of installed pumped storage by the end of 2024 after adding 7.75 GW that year, while the International Hydropower Association’s 2026 outlook says China now has 218 GW of pumped storage under construction.

But pumped hydro is a civil infrastructure project, not a factory product. It needs geology, water, transmission, permitting, revenue certainty, patient capital and political tolerance, while batteries need factories, containers, inverters and interconnection. Both are constrained, but they are constrained in different ways over a century-long scenario. The UK LDES portfolio shows the same role split at smaller scale: Li-ion batteries dominate project count, while pumped hydro carries most of the implied energy. The updated pathway therefore keeps pumped hydro as the long-life bulk anchor without pretending capital projects will outscale manufactured storage everywhere.

Flow batteries remain in the projection as a secondary medium-duration class. Flow batteries have real virtues, including stationary design, decoupled power and energy, potentially long cycle life and chemistries that may avoid some lithium-ion constraints. Grid storage, however, is won by repeat procurement, financeable warranties, delivered cost, bankable performance and operating fleets. Cheap batteries have narrowed the lane flow expected to occupy, so flow/redox remains material by 2100, but not co-dominant with batteries and pumped hydro.

The “Other electrical LDES” category is treated cautiously. Some ideas in that basket may find niches, but a base-case projection should not allocate tens of TWh to compressed air, liquid air, gravity blocks, iron-air, thermal-to-electric systems or other mechanisms simply because they claim the long-duration label. The UK’s first LDES support window does not change that treatment. It shows some diversity, including CAES and VFB/Zn, but the portfolio weight sits overwhelmingly with pumped hydro and Li-ion BESS. That is useful evidence of procurement interest, not evidence for letting “Other LDES” dominate a 2100 base case.

The updated base case lands at 108.5 TWh of dedicated electrical storage by 2100, but that number should not be read as a point prediction or as a figure borrowed from another model. It is a TFIE scenario anchor. The useful conclusion is that a mostly electrified world plausibly needs on the order of a hundred TWh of dedicated electrical storage, with batteries providing the largest share, pumped hydro providing the long-life bulk anchor, flow/redox providing a secondary medium-duration class and other electrical storage ideas remaining small until deployment evidence forces an update.

The public conclusion is straightforward. Batteries are now the strongest scaling signal. Pumped hydro remains the best large physical storage asset. Flow batteries retain a narrower but still material role. Other LDES has to earn its way into the model with operating fleets, not announcements or category claims. The updated pathway is not batteries-only, but it is batteries-led, and the rest of the reliability stack matters because storage should not be forced to solve problems that flexibility, heat, transmission and strategic reserve solve better.

Below the paywall is the professional layer: the storage boundary, provenance of the 108.5 TWh and 9.2 TW scenario anchors, comparison with full-electrification and renewables studies, the UK and China evidence signals, system-lever treatment, update triggers, decision implications and scorecard I’ll use to judge whether grid storage technologies are scaling, progressing, niche-valid, stalled or still not demonstrated at fleet scale.

UK firm CPH2’s destroyed 1 MW hydrogen electrolyzer is useful because it failed in a way that clarifies a recurring hydrogen startup problem. Test failures happen. New industrial equipment breaks, trips, leaks, overheats, refuses to start, refuses to stop and occasionally teaches engineers something expensive. The interesting question is not whether a novel hydrogen system can have a bad test. The interesting question is why this particular company, with this particular architecture and public-market story, was still presenting itself as if the hardest system questions had already been answered.

This was not a trivial failure by a two-year lab startup. CPH2 traces its origins to Ireland in 2012, established the UK operating company in 2016, raised £2.5 million from angel investors in 2019, raised another £3 million from private investors in 2020, listed on AIM in 2022 after a £30.5 million gross raise, and then raised £13.7 million gross in 2025. Add the £338,000 Innovate UK grant and the undisclosed 2017 external round, and this was roughly a £50 million disclosed-funding story before the 2026 rescue raise. It also had a public-company board, nominated adviser, broker, company secretary, legal counsel and communications adviser around it. That makes the failure harder, not easier, to excuse. After roughly a decade of UK development, a public listing, repeated capital raises and a governance structure that should have been asking hard stage-gate questions, why was a 1 MW mixed hydrogen-oxygen system still able to fail destructively during an automated shutdown sequence, and why was CPH2 still presenting the architecture as proven before that question had been answered?

The location of the failure is what makes the case so clean. CPH2’s advertised breakthrough is a membrane-free electrolyzer, but its own process description says mixed hydrogen and oxygen gas is generated in the stack, moves through the balance of plant to dryers, and then enters cryogenic separation. After the incident, CPH2 said the MFE220 could not be repaired to continue testing and required substantial redesign of the mixed gas system to operate safely in all conditions. That is the real business. Not just the stack. Not just the patent. Not just the attractive avoidance of membranes, platinum group metals and PFAS. The business is the full industrial system that safely creates, dries, cools, separates, depressurizes, controls, services and warranties hydrogen and oxygen streams.

CPH2’s 1 MW MFE220 unit was in the final stages of factory acceptance testing at its Rossington test site when an unexpected error caused it to enter a standard shutdown procedure. During that shutdown, according to the company, an incident caused significant damage to the equipment. A week later, CPH2 said the unit could not be repaired to continue testing and that its Chief Technical Officer and Chief Operations Director had advised the board that the MFE220 required substantial redesign of the mixed gas system to operate safely in all conditions. The board also concluded that the company did not have the financial, engineering or technical resources to undertake that programme at the time.

The company later said its initial internal assessment was that a hydrogen and oxygen mixture ignited during automated depressurization, causing loss of containment. That is not a generic “hydrogen is hard” anecdote. It is the central risk surface of this specific architecture showing up during a standard system state: shutdown. The later fundraising disclosure added potential contributors including moisture through the cryogenic separation unit, possible particles and a valve velocity apparently exceeding EIGA standards. Those are ordinary industrial details, which is precisely why they matter.

A lot of hydrogen startups have versions of this problem. The promoted object is a fuel cell, electrolyzer stack, tank, aircraft powertrain, truck, modular refuelling concept or production pathway. Then the real product boundary expands. The company is also responsible for water quality, power electronics, drying, cooling, compression, storage, oxygen compatibility, valves, sensors, purges, controls, hazardous-area design, field service, warranty reserves, insurance, permitting, customer training and capital structure. None of those are peripheral when the system has to operate safely and repeatedly.

This is why “uses known components” is not the reassurance people often think it is. Known components in hydrogen and oxygen service are not automatically low-risk components. Oxygen purity changes materials and cleanliness requirements. Hydrogen adds demanding leak detection, ventilation, ignition control, purge logic and maintenance requirements. Compressors, dryers, valves, chillers, seals, sensors and controls become the practical safety case. The novelty may sit in the stack, but the customer does not buy a stack. The customer buys uptime, compliance, serviceability, insurability and someone else’s balance sheet behind the warranty.

That is the strategic failure CPH2 exposes. It appears to have tried to be inventor, stack developer, mixed-gas process integrator, manufacturer, deployer, licensor and public-market growth story on a small-company capital base. The board did not need to know more electrochemistry than the CTO. It needed to know what business the company was actually in. A membrane-free electrolyzer company that deliberately creates a mixed hydrogen and oxygen stream before separation is not merely an electrolyzer company. It is a hazardous process equipment company.

That distinction should have driven the strategy. If the core capability was the stack and process IP, then cryogenic separation, oxygen-service engineering, process safety, manufacturing quality, installation and field support should have been placed under industrial partners with accountable design authority much earlier and much more deeply. If CPH2 wanted to own the full system, then it needed the capital, staff, safety maturity and validation discipline of a real industrial OEM. What it could not safely be was a lightly capitalized listed growth story with a complex hazardous process wrapped around a claimed simple breakthrough.

The broader hydrogen reference class has two connected patterns: product-boundary denial and capital-market survival. I have covered the second pattern separately as the hydrogen recapitalization cycle: decades of hydrogen-for-energy firms surviving through enthusiasm waves, share issuance, retrenchment and renewed narratives rather than durable operating profits. That matters here because CPH2 is not an outlier in kind. It is an unusually clean example of what happens when the industrial-system burden catches up before the next financing story can carry it.

Plug Power shows what happens when a hydrogen firm tries to own much more of the ecosystem itself. It has more operating substance than many hydrogen companies, including production plants, delivery, customer-site equipment, service, fuel logistics and large customer relationships. That also means more of the hard parts sit on its own balance sheet. By late 2025, I had described Plug as being in a hydrogen maintenance and cash-burn squeeze, suspending DOE-backed green hydrogen projects, looking for liquidity through electricity-right monetization and restricted-cash release, and cutting maintenance costs. For a company running hydrogen production plants, maintenance is not a back-office saving. Compressors, cryogenic systems, valves, seals and leak detection are part of the safety case. When the financial strategy starts leaning on those budgets, the system boundary has reached the workforce.

Ballard shows the narrower-boundary version. For most of its life, it managed to keep the hardest parts of hydrogen commercialization as other people’s problem. It sold stacks, modules and promises into buses, trucks, marine trials, rail trials and stationary applications, while customers, integrators, governments and project developers carried much of the vehicle, fuel, infrastructure, utilization and service burden. That helped Ballard survive for decades through losses, re-raises and dilution because the company could stay close enough to the attractive hydrogen component story without owning the full industrial system.

The recently announced GeoPura acquisition changes the category. Ballard described the deal as a move toward an integrated hydrogen ecosystem provider, expanding from fuel-cell supply into hydrogen production, distribution, logistics, refuelling and stationary power generation. That sounds more complete, but it also means more of the hard parts move onto Ballard’s side of the ledger. GeoPura brings hydrogen power units, electrolyzers, tube trailers, manifolded cylinder packs, employees, customers, field assets and operating obligations. It is not just a module buyer. It is the operating interface between hydrogen equipment and users who need power.

That makes Ballard useful here because it shows both sides of the product-boundary problem. The old Ballard model kept the boundary narrow enough to keep raising capital around the component story, even while continuing to lose money every year since its IPO decades ago. The GeoPura deal pulls more of the system inside the company, but it does so through the familiar hydrogen finance pattern: partial cash, a large block of newly issued shares and sellers exposed to Ballard paper, and dilution of equity for existing investors. It may give Ballard a more defensible application than many hydrogen mobility stories. It also makes the operating burden harder to keep off the balance sheet.

The vehicle and aircraft examples make the same product-boundary problem visible in a different form. Nikola put hydrogen trucks on the road and dispensed hydrogen, but still filed for Chapter 11 in 2025. Hyzon shareholders later approved the liquidation and dissolution of the company. Universal Hydrogen flew a demonstrator and then shut down after failing to raise more financing. ZeroAvia is still alive, but its plan has narrowed toward fuel-cell systems while broader powertrain ambitions have slowed. These companies are not the same, but the pattern is familiar: the pitch starts with a hydrogen component, truck or aircraft and ends up needing an industrial system, fuel supply chain, maintenance model, customer operating change and financing structure.

There are partial counterexamples, but they mostly prove the rule. More credible hydrogen industrialization comes from companies that either narrow the product boundary or bring industrial-system depth to it. ITM Power’s FY2025 results are not a story of easy hydrogen scale-up. They discuss product simplification, cost and capital discipline, manufacturing debottlenecking, factory acceptance test pass-rate improvement, full-scope containerized plants and a still-negative adjusted EBITDA. That is what seriousness looks like in this sector: less confidence around the molecule and more discipline around the plant.

The lesson is not that every hydrogen technology company is doomed, or that every hydrogen use case is nonsense. Hydrogen remains a large industrial molecule with real decarbonization work to do in places where it is already used. The lesson is that hydrogen startup claims should be tested at the system boundary, not at the promotional boundary.

When a company says it has solved the hydrogen bit, the diligence questions are straightforward. Who owns everything around it? Who validated abnormal operation, not just steady-state operation? Who is responsible for the dryer, valve, compressor, chiller, separator, sensor and control sequence? Who warranties the field unit? Who services it at 2 a.m.? Who pays when the routine component fails? Who has enough balance sheet to survive the answer?

CPH2 has not proven that hydrogen innovation is impossible. It has shown, rather usefully, that the hydrogen bit is not the product. The product is the whole industrial system around it, and that is where strategy, capital and safety either show up or fail.

The easiest way to misread Chinese aviation is to start with aircraft demand. Boeing’s China-specific market outlook calls for Chinese airlines to need 8,830 new commercial aircraft by 2043, a number that sounds plausible if China is treated as a normal aviation growth market. But China is not optimizing for aircraft demand first. It is optimizing for moving people, reducing strategic dependence, and controlling the industrial systems that remain necessary after the modal split is changed.

That distinction matters because China has already built the strongest competitor to short-haul aviation on the planet. In China’s 2025 transport data, railways carried 4.601 billion passenger trips and 1.640 trillion passenger-kilometres, while civil aviation carried 770 million passengers and 1.399 trillion passenger-kilometres. Aviation remains important, but the average trip length tells the story: rail is doing the mass movement of people, while aviation is increasingly pushed toward the longer-distance layer where speed over distance still wins.

The sub-1,000 km market is where Boeing-style aviation growth curves are weakest. A 600 km or 900 km flight can look efficient in an aircraft demand model, but passengers do not travel from runway to runway. They travel from a district in one city to a district in another, through airport access, security, delays, bags, transfers, and city-centre recovery time. High-speed rail does not need to eliminate every short-haul flight to damage the aviation denominator. It only needs to become the default choice on enough dense corridors that airlines are left with thinner, more connection-dependent, or more geographically awkward routes.

China is still expanding that rail system from an already continental base. By the end of 2025, China had about 165,000 km of national railway, roughly 50,000 km of high-speed rail, and a network that was 76.8% electrified. Current planning points toward roughly 60,000 km of high-speed rail by 2030. That additional build does not just add passenger capacity. It removes more trips from the future pool of routes that Western aircraft manufacturers would prefer to count as narrowbody demand.

This is not an argument that Chinese aviation collapses. The transport data says the opposite. Aviation passenger-kilometres remain large because aircraft carry longer trips, and international travel has been recovering from a lower base. The point is narrower and more consequential: Chinese aviation growth becomes more selective. It shifts toward longer domestic routes, western and less rail-served corridors, international recovery, hub traffic, freight, and places where geography still favours aircraft. Dense short- and medium-distance domestic routes are being contested by state-built electric rail, not left for airlines to fill by default.

COMAC sits inside that same mobility strategy. The C919 does not need to defeat the 737 MAX or A320neo globally this decade to be strategically useful. It needs to fly domestic Chinese routes, build airline operating experience, train pilots and maintenance crews, mature CAAC certification practice, and turn state-airline procurement into industrial learning. Even the current production numbers show the scale gap. The C919 is moving from demonstration to early fleet absorption, not to Airbus-scale production, while COMAC is still ramping C919 production capacity from a much smaller base.

That is the link between modal shift and aerospace sovereignty. Rail reduces the size of the domestic short-haul aviation pool. COMAC is being assigned a growing share of the domestic narrowbody pool that remains. Low-altitude aviation, drones, electric aircraft, and eVTOLs are the adjacent learning layer rather than the core passenger story. They matter because they give China more battery, autonomy, airspace-management, certification, and aviation-manufacturing experience. Some flying-taxi claims will age badly, as they usually do, but the industrial learning is real even when the pitch deck is not.

China’s geographically awkward short hops are the place where the next aviation denominator shift should appear. Routes that are too short for jets to be efficient, too awkward for high-speed rail to serve well, and too important to abandon are natural candidates for hybrid-electric turboprops. China already has a certified four-seat electric civil aircraft in the RX4E, a low-altitude aviation sector being pulled into formal regulation, and battery giants such as CATL pushing higher-energy-density aviation batteries. My expectation is that China is more likely than the United States or Europe to be first to build, certify, and deploy an up-to-100-passenger hybrid-electric aircraft for inconvenient regional routes. That would hit Boeing’s China projection from the other side. High-speed rail erodes the dense sub-1,000 km corridors, while hybrid-electric turboprops can take the thinner short-hop routes that rail does not reach. The result is not fewer Chinese passengers moving. It is fewer of those passengers requiring Boeing-style narrowbody jets.

Boeing is the obvious collateral damage. During the tariff war, Chinese customers refused new Boeing deliveries and Boeing began redirecting aircraft. China accounted for about 10% of Boeing’s commercial backlog; Boeing had roughly 50 China deliveries scheduled for the rest of the year, 41 already-built or in-production jets to reassign, and 130 unfilled Chinese orders, including 96 737 MAXs. That was not a routine ordering pause. It showed how easily Boeing aircraft could become instruments in a wider sovereignty negotiation.

The later signal of a 200-jet Boeing tranche did not restore the old model either, because the important detail was not just the aircraft. It was the requirement for parts support. Boeing said it could provide aftermarket parts support for the order, with its services chief adding that there would be no problem supplying China “if it’s a part that we’re allowed to sell globally.” China may still buy Boeing aircraft, but it increasingly buys them as conditional capacity inside a managed supply-chain bargain.

Airbus is the completeness case, and for now the stronger Western supplier. It has less direct exposure to U.S.-China conflict, a deeper local industrial presence through Tianjin, and recent order momentum from Chinese airlines. China Eastern’s A330neo order followed a much larger A320neo-family agreement and was explicitly tied to international-route growth from Shanghai Pudong. That gives Airbus the bridge role Boeing has made harder for itself to hold.

Bridge is the key word. China’s strategy is not to replace Boeing dependency with Airbus dependency. Airbus buys time, capacity, and political flexibility while COMAC and the domestic aerospace supply chain mature. This is the same pattern that showed up in high-speed rail, batteries, solar, EVs, shipbuilding, and grid equipment: foreign technology or foreign suppliers can be useful on the way to domestic capability, but they are not the intended endpoint.

The useful question is no longer how many aircraft China needs in a generic passenger growth model. It is how many aircraft China needs after high-speed rail has removed a large share of sub-1,000 km demand from the pool, how much of the remaining domestic narrowbody market COMAC can absorb, how much of the geographically inconvenient short-hop market moves to hybrid-electric turboprops, how much Western capacity is still needed for reliability and international growth, and how much political risk Beijing is willing to tolerate in each supplier relationship.

That framing does not make Boeing irrelevant. It makes Boeing optional. Boeing will probably keep selling aircraft to China in tranches when the political price is right, airline fleet needs are pressing, or Beijing wants leverage in a broader negotiation. Airbus will likely sell more smoothly through the late 2020s. COMAC will remain slower and less globally certified than the incumbents for some time. But the direction is not hard to see. China is moving people with rail where rail works, flying people where flying still makes sense, electrifying awkward regional aviation where batteries can change the economics, and building the aircraft industry it needs for the part of mobility that remains in the air.

Boeing’s China projection becomes collateral damage because it preserves the old denominator. China is changing it. That is the point most aircraft demand forecasts miss: China is not merely a future aircraft customer. It is turning passenger mobility into an electrified rail system where possible, an aviation system where necessary, and an aerospace sovereignty project where dependence remains.

China’s heavy-truck electrification plan changes the oil demand argument because it reaches the part of transport fuel that vehicle counts tend to hide. Passenger EVs are the visible story. They are large, obvious and already undermining gasoline growth. Heavy trucks are less visible, but they burn diesel at high utilization, and China is now moving them from scattered electric models into a coordinated freight system.

That matters for any oil demand forecast that still treats China as the dependable growth engine for crude. The IEA’s Oil 2025 says Chinese oil demand rose by nearly 6 million barrels per day from 2015 to 2024, equal to about 60% of global oil-demand growth over that period. It now expects a very different 2030 picture, with China’s oil demand peaking this decade as EVs, LNG trucks, high-speed rail and structural economic shifts weaken road-fuel demand. The IEA is already closer to the right direction than forecasts that still treat China as a combustion-growth engine, but even that may understate the freight shift now underway.

China’s new heavy-truck plan targets 40% new-energy heavy-truck sales by 2030, more than 1.6 million vehicles in the fleet, about 20% of the total heavy-truck fleet and 18% of highway freight volume. Those are not passenger-car adoption numbers translated into a larger vehicle class. They are freight numbers. The relevant denominator is not how many trucks exist. It is how much diesel is burned by the trucks that move large shares of highway freight every day.

That was the point of my earlier Briefing piece on China’s truck plan. China did not merely create a target for electric trucks. It attached electric trucks to corridors, depots, charging, battery swapping, logistics parks, service areas, grid planning, standards, repair networks, insurance and priority freight use cases. The plan calls for roughly 30,000 km of zero-carbon highway freight corridors and about 3,000 heavy-truck charging and swapping stations, with grid companies told to include heavy-truck charging and swapping demand in distribution-grid planning. That is the difference between counting electric vehicles and watching a diesel system start to lose load.

A few electric trucks in pilots are an adoption signal. Electric trucks tied to freight corridors, depots, mines, ports, logistics parks and grid upgrades are a diesel displacement signal. Oil models that treat truck electrification as a sales-share curve risk missing the system being built around the trucks, and that system matters because freight is not a casual consumer market. Fleet operators care about uptime, route certainty, delivered energy cost, maintenance, financing and whether the equipment can be dispatched tomorrow without special handling. China’s plan is aimed at those dull operational details, which is why it deserves more attention than another round number on a target slide.

The bottom-up diesel effect is already large enough to matter. A 20% electric share of China’s heavy-truck fleet aimed at 18% of highway freight volume plausibly removes several hundred thousand barrels per day of diesel demand by 2030. The range depends on which trucks are replaced. China’s scrappage focus makes the high end more credible because older diesel trucks are being pushed out, although not every old vehicle is a high-mileage vehicle. That caveat matters for passenger cars. It matters less for commercially active heavy trucks, where an old vehicle that is still in service is more likely to be burning meaningful fuel.

Electric trucks are not the only diesel wedge. LNG trucks are not a climate solution, but they are oil displacement from Beijing’s perspective. Chinese state-linked researchers cited by Reuters expect LNG heavy trucks to replace 38 million tons of diesel, or about 775,000 barrels per day, by 2030. The same reporting said EVs were already replacing at least 25 million tons of gasoline, or 582,000 barrels per day, in 2025. Add passenger EVs, electric trucks, LNG trucks, high-speed rail, weaker construction diesel and urban logistics electrification, and the transport-fuel story that supported China’s oil growth looks increasingly thin.

This is where OPEC’s latest reported oil outlook becomes exposed. OPEC still sees global oil demand rising from about 105 million barrels per day in 2025 to more than 113 million barrels per day in 2030, with no peak through 2050. That outlook does not require China alone to do all of the work, but it does require China’s road-fuel losses to be offset by petrochemicals, aviation, slower electrification elsewhere and rising demand in other emerging markets. That is a possible pathway, but it is no longer the clean China-led growth story oil markets became accustomed to using.

The import story is more complicated, and that is where the analysis can overreach. China’s crude imports are not the same thing as China’s transport fuel demand. China imported about 11.55 million barrels per day of crude in 2025, but Rystad estimated that stockbuilding accounted for about 430,000 barrels per day of that. Customs import data can stay high when Beijing is filling storage, when refiners are taking advantage of prices or sanctions discounts, or when petrochemical demand absorbs more crude and products. Falling gasoline and diesel demand does not immediately produce a clean one-for-one fall in crude imports.

But that caveat does not rescue the old growth story. It separates durable demand from inventory behavior. If imports are being supported by storage, they are less useful as a signal of structural demand. If petrochemicals are becoming the main remaining growth pool, then oil has already lost the transport engine that made China such a reliable demand story. Petrochemicals can absorb barrels. They do not recreate the old pattern of more cars, more trucks, more road freight and more diesel.

The professional distinction is now between oil demand plateau and crude import contraction. Agencies mostly forecast demand. Exporters and refiners live with flows, margins, product demand and storage behavior. China can keep importing heavily for a while even as road fuels weaken, especially when prices are attractive and energy-security logic favours stockbuilding. That does not restore the growth path. It only changes how long the transport-fuel decline is masked in headline import data.

China’s truck plan therefore makes oil forecasts wrong in different ways. The IEA has already shifted from China as growth engine to China as peak-this-decade, which is the right directional move. OPEC-style outlooks remain more dependent on combustion demand being replaced elsewhere before China’s losses become visible in the global total. The more China turns freight electrification into corridors, charging, swapping, depots and grid planning, the harder it is to treat diesel demand as a slow-moving legacy variable.

The point is not that every Chinese truck becomes electric by 2030. China’s own target says most will not. The point is that a 20% electric fleet share, aimed at 18% of highway freight volume and concentrated in high-use corridors, is enough to matter at national diesel scale. It is enough to matter to crude import expectations. And it is enough to make oil demand forecasts built around the previous Chinese freight system increasingly unreliable.

Canada’s electricity strategy has reached the point where the useful question is no longer what Ottawa intends. It is which provincial boundary a wire crosses, how much power can move across it, who pays for the asset, who owns the right to build it, and whether the line changes grid operation after it is energized.

That is why CBC’s reporting on Tim Hodgson’s priority interties matters. Canada has had no shortage of clean electricity language, nation-building language, energy-security language, affordability language and industrial-strategy language. The harder test is whether any of it turns into transmission capacity, converter stations, substations, interconnection agreements, Indigenous equity structures, permits and construction crews.

The broader federal strategy is large enough to become abstract. Reuters reported that Ottawa is talking about a C$1 trillion effort to double Canada’s electricity grid capacity by 2050, driven by industrial growth, data centers, electric vehicles and energy security. The same reporting noted the structural problem that Canada’s regional grids trade more with the United States than with each other, while U.S. electricity imports into Canada have increased every year since 2020. That is the right problem to be solving, because Canada does not have a single electricity system in any meaningful operational sense. It has provincial and regional systems with uneven resources, uneven demand growth, uneven politics and a long history of north-south trade.

I have called the needed buildout a second golden spike, but the phrase needs practical boundaries. The useful version is not one heroic coast-to-coast wire. It is a sequence of interties, upgrades, HVDC links where distance and grid conditions justify them, stronger hydro-to-fossil-province balancing, better Atlantic integration, northern diesel displacement and enough grid-enhancing work to use the existing system more effectively. The real strategy is the build order, not the patriotic and nostalgic slogan.

The reported first tranche is therefore both modest and important: BC–Yukon, Alberta–BC, Alberta–Saskatchewan, Saskatchewan–Manitoba and PEI–New Brunswick. This is not yet a national electricity spine. It is a set of useful links and repairs that begin to make the national strategy measurable. Five named interties are better than another grid strategy built around general commitments, but they should be judged as the beginning of the project, not as evidence that Canada has solved the grid problem.

The denominator is not the number of interties in a press release. It is transfer capacity, expected annual energy flow, reliability value, avoided fossil generation, exposure to U.S. imports and exports, cost allocation, permitting status, Indigenous ownership or benefit structure, and the specific bottleneck each project relieves. A transmission project that appears in a strategy is still only a strategy entry. A transmission project that changes dispatch across a provincial boundary is an electricity asset.

That is why Saskatchewan–Manitoba is the most strategically interesting of the group. Manitoba has hydro flexibility. Saskatchewan has fossil-heavy generation and large wind and solar potential. More transfer capacity between those systems can turn regional differences into system value: hydro backing variable renewables, clean surplus moving when useful, and some share of duplicated provincial backup being avoided. The value is not the line itself. The value is the operational flexibility it enables.

The other links have different tests. BC–Yukon is about northern load growth, mining, community resilience and the replacement of diesel logistics with grid electricity where that is practical. Alberta–BC and Alberta–Saskatchewan are about fossil-heavy systems, clean import options, export opportunities and the political reality that Alberta’s grid transition will be built through assets, markets and regulation, not through national averages. PEI–New Brunswick is about Maritime reliability, subsea vulnerability and whether Atlantic renewable potential becomes a grid resource rather than a long-running planning theme.

This is where the old Canadian energy frame gets in the way. Canada knows how to think nationally about pipelines, export terminals, rail corridors and ports. It is much less comfortable thinking nationally about wires, even though electrification makes wires strategic infrastructure. I have argued before that HVDC is the new pipeline, not because every intertie should be HVDC, but because long-distance energy transport increasingly shifts from moving molecules to moving electrons. The point is not the acronym. The point is the change in infrastructure priority.

That shift does not remove the delivery problem. Electricity is provincial in Canada in the legal, regulatory, operational and political senses of the word. Ottawa can finance, convene, set tax-credit rules, use the Canada Infrastructure Bank, refer projects into major-project machinery and lower the cost of capital. It still has to work through provinces, utilities, regulators, landowners, ratepayers and Indigenous governments. Those are not secondary issues around the grid. They are part of building the grid.

That is also why the first list should not be dismissed for being incomplete. A more complete national map would put Ontario–Quebec and Manitoba–Ontario closer to the center of the conversation. It would show how Atlantic wind becomes dispatchable value rather than an export brochure. It would distinguish reliability upgrades from decarbonization links, industrial-load links and northern fuel-displacement links. It would also separate transmission that requires a decade of permitting from grid-enhancing technologies that can increase useful capacity on existing corridors much faster.

The workforce and supply-chain reality is just as material. AP reported that the federal strategy anticipates 130,000 new workers will be needed to double the grid, and that the larger electricity plan still leaves major execution details to be resolved. A trillion-dollar grid strategy needs a named project pipeline, because manufacturers, utilities, training institutions and construction firms scale against procurements, standards, dates and credible financing.

The next step should be a public project ledger for each priority intertie. Capacity. Expected annual flows. Capital cost. Cost allocation. Reliability contribution. Avoided gas or diesel generation. Permitting milestones. Indigenous ownership or benefit model. Target in-service date. The bottleneck being relieved. The comparator being beaten. Without that, “priority” is a useful political signal, but not yet a delivery framework.

Canada has spent decades treating electricity as a provincial utility issue while treating fossil fuels as the national energy story. That worked politically until electrification made the grid the platform for industrial growth, household affordability, mining, data centers, transport, heating and energy security. National averages are not enough in that world. Canada’s clean electricity strengths are real, but they are unevenly distributed across hydro provinces, nuclear-heavy Ontario, fossil-heavy Alberta and Saskatchewan, wind-rich Atlantic provinces and diesel-dependent northern systems. The next energy system depends on moving more clean electricity between those systems, not just counting how clean the national average already is.

The second golden spike was never going to be a single ceremonial project. It was always going to begin as a set of interties that are easier to underrate than to build. That is fine. Serious infrastructure often starts as assets with difficult owners, difficult regulators and difficult cost-allocation arguments.

Five wires do not make a national spine. They do make the strategy harder to keep vague. Canada has started naming some of the places where the electrified economy has to cross provincial boundaries. The professional question now is whether those named links become the first tranche of a build order, or whether they remain a useful announcement in front of an unfinished grid.

Ballard Power’s acquisition of GeoPura is being sold as transformation. Ballard says it is becoming an integrated hydrogen ecosystem provider, moving from fuel-cell supply into hydrogen production, distribution, logistics, refuelling and stationary power generation. The more useful reading is harsher. Ballard is issuing another large block of stock to buy a new hydrogen story, while GeoPura’s investors take what looks like an exit but is mostly locked exposure to Ballard’s next dilution cycle.

The terms are the denominator. The deal is £275 million upfront, but only £82.5 million is cash. The rest is about 50.8 million newly issued Ballard shares, giving GeoPura holders about 14.4% of the pro forma company. Those shares are subject to lock-up agreements after closing. A clean strategic exit would convert years of private-company risk into cash. This converts much of that risk into Ballard paper.

That matters because the acquisition is not primarily a technology story. GeoPura’s hydrogen power units are one of the remotely plausible hydrogen-for-energy niches. Replacing diesel generators at construction sites, film sets, events, military facilities, hospitals, data centres and grid-constrained locations is more defensible than hydrogen cars, hydrogen home heating or ordinary hydrogen trucking. Diesel generators are dirty, noisy and increasingly awkward for customers with public climate commitments. Batteries as a service are constrained by regulation per my discussions with film industry service providers. GeoPura has equipment, customers, employees, field experience and an operating team. Those facts explain why the story is marketable. They do not prove the economics.

GeoPura was not being acquired from obvious financial strength. It had raised £36 million, then £56 million, then £22 million of asset-backed debt, for roughly £114 million raised over two years. At the same time, its own CFO had been talking about a 3,600-unit ambition requiring more than £2.5 billion of capital over the next decade. That is not normal growth capital. That is a financing wall with hydrogen branding.

Ballard’s investor deck says GeoPura has more than 60 HPUs, about 20 electrolyzers, 75 tube trailers, 150 manifolded cylinder packs, more than 180 employees and expected 2026 revenue of about £38 million. Put those figures beside the 3,600-unit ambition and the £2.5 billion capital requirement, and the shape of the deal changes. This was not a self-funding platform choosing the strongest strategic partner from a position of power. It looks like a capital-hungry private hydrogen company whose next cheque had become the problem.

That does not make GeoPura fake. It makes it a poor investor-return story unless someone else is willing to fund a very large expansion before the business has proved self-funding economics. The company may have a genuine diesel-generator displacement niche, but the capital requirement had run far ahead of the proven revenue base. GeoPura’s investors appear to have found an exit door, but it opened into Ballard.

Ballard is the other half of the same pattern. It still had cash at the end of Q1 2026, but cash is not a business model. Ballard also had modest quarterly revenue, continuing losses and a multi-billion-dollar accumulated deficit. Its own filings describe a liquidity strategy based on maintaining enough cash for at least six quarters of forecast operating cash use and contractual commitments while securing additional financing as needed until sustainable profitable operations are achieved. That is the formal version of the public hydrogen treadmill: preserve the runway, keep the story alive, point to the next market and finance the journey.

GeoPura gives Ballard a better next story. The old public hydrogen story has moved through fuel cells for mobility, buses, trucks, rail, marine, stationary power, resilience, data centres and energy-as-a-service. GeoPura gives Ballard a more defensible application and a more attractive customer narrative. It does not change the financing mechanism. Existing Ballard shareholders are diluted to buy the story, and GeoPura’s sellers become Ballard shareholders inside the same story.

The seller-side due diligence failure is not that GeoPura’s investors or advisers could not read Ballard’s filings. The risk was public. Ballard’s loss history, accumulated deficit, future financing language and share-issuance risk were not hidden. The failure was accepting Ballard shares as if they were strategic-buyer currency rather than dilution-cycle paper.

There are only two plausible explanations. Either GeoPura’s investors genuinely believe the combined company will re-rate and make Ballard stock a better asset than it looks today, or their alternatives were worse: another private raise, a down round, more asset debt, slower deployment, a narrower business or a buyer unwilling to pay mostly cash. The public evidence makes the second reading hard to dismiss.

The synergy story is the wrapper. Ballard already supplied fuel-cell engines to GeoPura. That was the obvious industrial overlap, and it already existed. Buying GeoPura does not create that relationship. It internalizes it and turns it into an acquisition story.

The hard part of GeoPura’s business is not merely the fuel-cell stack. It is hydrogen production, compression, storage, tube trailers, refuelling, deployed fleet operations, rental utilization, uptime guarantees, maintenance, site logistics and customer operations. That is GeoPura’s operating base, not Ballard’s demonstrated one. Ballard is not buying a missing component. It is buying the appearance of synergies, along with the operating team needed to make the appearance credible.

Andrew Cunningham’s move makes the structure clearer. GeoPura’s founder and CEO is expected to become President of Ballard, reporting to Marty Neese as CEO. That is part of the transaction architecture. Ballard needs Cunningham because GeoPura contains the operating story Ballard does not have. GeoPura needs Ballard because GeoPura’s capital requirement had outgrown the private growth story. Cunningham becomes the human bridge: founder credibility for Ballard, continuity for GeoPura customers and employees, and reassurance for sellers taking Ballard shares instead of clean cash.

But Cunningham is not becoming CEO. Neese remains CEO. Cunningham gets title, status, operational burden and public association with the new story. He also inherits the job of making GeoPura validate Ballard’s dilution. That is a good role if the stock re-rates and the economics work. It is a much worse role if the acquisition becomes another public hydrogen hope refresh with a later financing attached. That’s the reality of his new gig.

The employees get the hope refresh too. GeoPura has more than 180 employees. These are not abstract “green jobs.” They are engineers, technicians, logistics staff, operators, apprentices, commercial people and manufacturing partners. They were recruited into a company that promised UK industrial growth, green hydrogen skills and hundreds of future jobs. Now they are being folded into Ballard’s public-market survival story.

For them, the acquisition may feel like validation. There is a larger listed owner, global expansion language, founder continuity and a promise that GeoPura’s model will scale. That is the hopeful version. The harder version is that they become the buffer between the press release and the economics. If utilization disappoints, hydrogen costs remain high, Ballard stock weakens, synergies fail to materialize or the combined company needs another financing round, the pressure will not land first on the language in the investor deck. It will land on hiring plans, expansion roles, projects, support functions, discretionary spending and eventually headcount.

Hydrogen hype cycles do not just dilute shareholders. They recruit workers into industrial futures that will never arrive. These are real people, usually believing that they are doing real and positive work. This perpetuates their belief, keeps them out of the useful economy and defers their inevitable pivoting to actually positive engagement.

That is what makes this acquisition such a clean specimen. It compresses the hydrogen capital cycle into one transaction. Private hydrogen cash burn meets public hydrogen dilution capacity. GeoPura’s investors get partial cash and mostly locked Ballard paper. Ballard shareholders get diluted. Ballard gets a new growth story. Cunningham gets a bigger title. Employees get another round of faint hope. The market gets a larger total addressable market, another profitability target and another promise that this version of hydrogen is different.

GeoPura may be one of the less hopeless hydrogen for energy niches. That does not make it a self-funding business at the scale its investors needed. Ballard may be the logical buyer. That does not make it a strong buyer. Cunningham may be the right operator. That does not make the currency good. The employees may be doing real work. That does not make the financial structure healthy.

The simplest read is still the ugliest: GeoPura’s investors had a capital-hungry asset, Ballard had listed paper, and the transaction turned private hydrogen cash burn into public hydrogen dilution. The exit is not cash. It is entry into the next dilution cycle.

Diesel hydrogen-injection add-ons have been returning to the market for decades with new names, new boxes and the same claim structure. The current language is usually cleaner than the old water-fuel gadget language, but the move is familiar. A small device uses electricity from the diesel vehicle to split water, makes hydrogen or a hydrogen-oxygen gas mixture often marketed as HHO or oxyhydrogen, injects the gas into the intake, and then turns a narrow combustion or smoke result into a broader fuel-efficiency and carbon-reduction story.

Recently one of the principals of one of the firms reached out after reading one of my hydrogen analyses pitching one of these Rube Goldberg contraptions and making extraordinary claims, claims which were written out clearly on their website. I’ve looked at variants of these things four or five times in the past couple of decades, but never written down why they aren’t remotely climate solutions. The interaction triggered me to pull together an analyses of the past and current firms pitching this, their claims, the regulatory landscape, their claims and an analysis of why their claims are indefensible.

The defensible kernel is opacity, the measurement of how much visible smoke blocks light in an exhaust plume. If a little hydrogen or oxyhydrogen changes combustion conditions, visible smoke can change. That is not exotic, because soot formation is sensitive to local combustion conditions and smoke opacity is a real measurement. It is also a narrow measurement. Lower opacity means the exhaust looks less black under the test condition, not that the truck used less diesel, reduced carbon dioxide equivalent emissions, or made a modern engine’s emissions-control system unnecessary.

That distinction matters because the public claims in this category rarely stop at opacity. The pitch usually migrates from cleaner-looking exhaust to lower emissions, then to lower carbon, then to fuel savings, then to maintenance savings, and finally to some version of a green-hydrogen bridge for diesel fleets. The ladder is doing the work. Opacity is the measured or plausible result. Fuel savings and carbon dioxide equivalent reduction are the commercial claims, and the evidence for the first does not automatically travel to the second.

The system boundary is the problem. In these onboard-electrolyzer systems, the hydrogen is not an external fuel. It is made on the vehicle using electricity ultimately produced by the diesel engine. The chain is diesel fuel, engine shaft work, alternator electricity, electrolysis, hydrogen or HHO, intake, combustion, and back to the same engine. Every step has losses. If the device is sold as a combustion modifier, then the question is whether the combustion effect is large enough to overcome the alternator and electrolysis load. If the device is sold as a fuel saver, the question is even less forgiving: where did the saved energy come from?

There is no carbon accounting escape hatch here. Diesel carbon dioxide is closely tied to diesel gallons burned. If the device causes the truck to burn more diesel to power an electrolyzer, carbon dioxide rises. Hydrogen leakage or unburned hydrogen slip would add a smaller climate penalty on top, but it is not the main issue. The main issue is simpler and uglier: diesel-powered electrolysis adds load to the engine before any possible combustion benefit appears. The default expectation is a fuel penalty unless independent, protocol-grade testing proves otherwise.

The usual response is that the hydrogen is not meant to supply much energy. It is meant to improve combustion. That is the only serious version of the argument, but it does not rescue the class. If a tiny gas stream improves the combustion process enough to create measurable net fuel savings after the electrolysis load, that result should show up in controlled comparison tests using weighed fuel, with electrical load logged, gas flow measured, route and load controlled, emissions split by pollutant, and aftertreatment behavior recorded. It should not need fleet anecdotes, before-and-after stories, unreviewed dashboard data or a smoke test pressed into service as carbon evidence.

The strongest version of this class still has a weak climate case. A more serious vendor with structured third-party testing has reported modest fuel-savings results in a controlled test, not the large 15% to 25% claims that appear elsewhere in the category, and even that report did not show a noticeable carbon dioxide difference. A diesel-generator study of onboard HHO found the opposite pattern: fuel consumption rose as HHO injection increased, because the energy cost of producing the gas was not recovered by the combustion effect. That is exactly what the system boundary predicts.

The regulatory and warranty implications are not side issues. A device that changes intake gases, alternator load, combustion behavior, sensors, engine calibration, diesel particulate filter regeneration, selective catalytic reduction behavior, diesel exhaust fluid consumption or onboard diagnostic readiness is entering the emissions-control system, not merely clipping an accessory to the outside of the truck. The diesel particulate filter is the system that traps soot. Selective catalytic reduction is the system that uses diesel exhaust fluid to reduce nitrogen oxides. Onboard diagnostics are the vehicle’s monitoring and fault-reporting systems. Claims about “no diesel particulate filter” or “no diesel exhaust fluid” are therefore not just marketing claims. They are regulatory claims. For modern certified diesel engines, they require engine-family-specific evidence that the vehicle remains compliant in the configuration being sold and installed.

This article is not about purpose-built hydrogen internal-combustion engines. It is not about externally supplied hydrogen dual-fuel demonstrations where hydrogen is stored onboard as a second fuel and actually displaces diesel. Those are different claims with different problems. This is about onboard hydrogen-on-demand or HHO devices added to diesel engines, especially systems that use the vehicle’s own electrical system to make hydrogen from water while the engine is running. That category should not be allowed to borrow credibility from external green hydrogen, fuel cells or clean-sheet engine programs.

The real comparator is not a dirtier diesel engine from another era. For local soot and criteria pollutants, the comparator is proper maintenance, certified aftertreatment, cleaner certified engines and compliance with the system the truck was designed to use. For climate, the comparator is reduced fuel use, freight efficiency, route optimization, modal shift where relevant, battery-electric trucks across the duty cycles they can already serve, and retirement or replacement of old diesel assets as economics allow. An aftermarket electrolyzer has to beat those options on delivered outcome, not on a photo of a cleaner-looking exhaust stack.

The cleanest public verdict is narrow. Hydrogen injection can plausibly affect smoke opacity under defined conditions. That is not enough. The fuel-savings claim is not credible. The carbon dioxide equivalent claim is not credible. Diesel particulate filter and diesel exhaust fluid avoidance claims are regulatory red flags unless covered by specific certification, exemption or compliance evidence. The climate claim should not leave the starting line until those tests are passed.
