EKPO Stack Heads Into a 40-Tonne Hydrogen Truck at 360 kW
EKPO Fuel Cell and Akkodis will put an EKPO stack into a 40-tonne hydrogen truck rated at up to 360 kW of system output, with the test data aimed at shipping, stationary power and off-highway uses.
Germany's EKPO Fuel Cell and Swiss digital engineering firm Akkodis will integrate and test an EKPO fuel cell stack in a 40-tonne hydrogen truck delivering system output of up to 360 kW, using the test data to develop future fuel cell systems for stationary power, shipping and off-highway machinery.
A German fuel cell maker and a Swiss engineering house are about to find out what a heavy truck does to a stack under real load. EKPO Fuel Cell and Akkodis, a Swiss specialist in digital engineering, said they will shortly integrate and test an EKPO fuel cell stack in a hydrogen truck, with the demonstration vehicle reaching system output of up to 360 kW. The vehicle is a 40-tonne truck — the heaviest class on European roads and the segment where battery-electric powertrains face their toughest arithmetic on weight, payload and recharge time.
The stated purpose is not a product launch. It is data. The two partners plan to feed what they learn from the truck into the design of future fuel cell systems, and they explicitly name applications beyond road freight: stationary energy supply, shipping and off-highway machinery. That framing is the most commercially revealing part of the announcement, and it says a great deal about where hydrogen suppliers now expect their volume to come from.
Why 360 kW and 40 tonnes are the numbers that matter
Output of up to 360 kW at the system level puts this demonstrator in the range engineers consider necessary for a fully laden articulated truck working gradients at motorway speed. A stack that performs on a bench at steady state is a different proposition from one asked to swing between idle and full draw thousands of times a day, in vibration, in road salt, in summer heat. Integration — the plumbing, the cooling, the control software, the balance of plant that surrounds the stack — is where most heavy-duty fuel cell programmes actually stall.
That is why the Akkodis half of the pairing is worth noting. This is not a truck maker partnering with a stack maker to sell trucks. It is a component supplier partnering with an engineering services firm to generate validated data on how the component behaves inside a vehicle. Digital engineering in this context means modelling, instrumentation, simulation and the test-and-measure loop that turns field behaviour into design rules. The truck, in effect, is the instrument.
The 40-tonne class is also the one segment where the hydrogen case has never fully collapsed. Long-haul freight at maximum gross weight is where charging downtime, battery mass and depot power constraints bite hardest. Even operators who have written off hydrogen for vans and city buses keep a watching brief on the heaviest, longest duty cycles.
A demonstrator arriving into a bruised market
The context for this test cannot be separated from the state of the heavy-duty hydrogen sector. Truck programmes have been shelved or slowed across Europe, refuelling networks have been built and in places dismantled, and the gap between announced hydrogen corridors and functioning pumps has widened rather than closed. Fuel cell equities have been among the most punished corners of the clean-energy complex, and capital for pre-revenue hydrogen mobility is scarce and expensive.
Against that backdrop, a two-party demonstrator with a defined data objective and no promised production date looks less like optimism and more like discipline. The details of the project were reported by electrive. Neither partner has attached a commercial volume commitment to the work, and no customer for a series product has been named.
It also matters that EKPO is not a listed pure-play. Investors who want exposure to fuel cell stacks through public markets have had to buy names whose share prices carry the full weight of sector sentiment, dilution risk and cash-burn scrutiny. A supplier sitting inside a larger automotive-components structure can keep developing a stack through a downcycle without a quarterly referendum on its survival. That structural advantage is arguably as important to this programme's odds as any engineering milestone.
The multi-sector hedge hidden in the press release
The three adjacent markets named — stationary energy supply, shipping and off-highway machinery — are not decoration. They are the hedge.
- Stationary power. Data centres, backup generation and grid-edge assets need firm, dispatchable output. Duty cycles are gentler than a truck's, tolerance for weight and volume is far higher, and the customer often values uptime over cost per kilowatt.
- Shipping. Marine propulsion and auxiliary power face tightening emissions rules with few drop-in alternatives at scale. Vessels can carry bulky tanks that a tractor unit cannot.
- Off-highway machinery. Mining equipment, port handlers and construction plant return to a single depot, which solves the refuelling problem that open-road trucking has not.
The three adjacent markets named — stationary energy supply, shipping and off-highway machinery — are not decoration.
A stack qualified against the punishing thermal and vibration profile of a 40-tonne truck is, by definition, over-qualified for a stationary installation. Development spend on the hardest application can therefore be amortised across the easier ones — which is precisely the logic a supplier needs when the anchor market for road freight is not yet ordering in volume.
Where the wider market stood as this landed
The announcement arrived on a firm session for risk assets. As of the last trade at 17:45 GMT on 27 August 2026, the S&P 500 tracker (NYSEARCA: SPY) was at $771.69, up 0.73% from a previous close of $766.08, with a day range of $767.16 to $772.36. The Nasdaq 100 fund (NASDAQ: QQQ) was stronger still at $719.54, up 1.15% against $711.37, having traded between $714.52 and $720.63. The Dow tracker (NYSEARCA: DIA) was at $536.20, ahead 0.37% from $534.23.
None of that reflects hydrogen sentiment specifically — the broad tape has been carried by large-cap technology rather than by industrial decarbonisation names. But it is a useful reminder of the competition for capital. Money is finding easier returns elsewhere, which is exactly why hydrogen projects announced in 2026 tend to be modest, partnered and data-driven rather than capital-heavy and volume-committed.
What would make this project count
Three things are worth tracking. First, whether the partners publish quantified durability results rather than a completion notice — hours at rated load, degradation per thousand hours, cold-start behaviour. Those are the metrics fleet buyers actually price. Second, whether any truck OEM or fleet operator is named as a participant or follow-on customer; a demonstrator without a route to a platform stays a demonstrator. Third, whether the promised crossover into stationary, marine or off-highway work produces an actual order, because that is where near-term revenue is more plausible than in long-haul freight.
For now, the verifiable content is narrow and worth stating plainly: a stack, a 40-tonne truck, up to 360 kW of system output, and a commitment to turn the resulting data into future products across several sectors. In a market that has spent two years discounting hydrogen promises, a project defined by what it will measure rather than what it will sell is a reasonable place to start again.

Frequently asked questions
What are EKPO and Akkodis actually building?
They are integrating a fuel cell stack made by Germany's EKPO Fuel Cell into a 40-tonne hydrogen truck and then testing it. The demonstration vehicle achieves system output of up to 360 kW. Akkodis, a Swiss digital engineering specialist, brings the modelling, instrumentation and test capability. The stated goal is validated data rather than a production vehicle.
Why does 360 kW matter for a heavy truck?
Output of up to 360 kW at system level is in the range engineers regard as necessary for a fully laden articulated truck to hold motorway speed and climb gradients. It is a demanding target because a stack in a truck must swing repeatedly between low and full load under vibration and wide temperature ranges, not run at steady state on a bench.
What other applications are the partners targeting?
The partners say data from the truck will inform future fuel cell systems for stationary energy supply, shipping and off-highway machinery. Those markets tolerate more weight and volume than road freight and often involve depot-based refuelling, which removes the public infrastructure problem that has held back hydrogen trucking.
Is EKPO Fuel Cell a publicly traded company?
EKPO Fuel Cell is described as a German company and is not a listed pure-play fuel cell stock. Investors seeking exposure to stack technology through public markets have generally had to buy standalone fuel cell names, which carry the full weight of sector sentiment and cash-burn scrutiny that a privately held supplier can avoid.
Has a truck manufacturer or fleet been named?
No truck maker, fleet operator or series-production customer has been identified in connection with the project, and no volume commitment or production date has been announced. The work is framed as integration and testing to generate engineering data, which is a step ahead of, not equivalent to, a commercial platform programme.
How were equity markets trading when the news landed?
As of the last trade at 17:45 GMT on 27 August 2026, the S&P 500 tracker SPY was at $771.69, up 0.73%, the Nasdaq 100 fund QQQ was at $719.54, up 1.15%, and the Dow tracker DIA stood at $536.20, up 0.37%. The strength reflected large-cap technology rather than industrial decarbonisation names.
