The recent investigative reporting by Swedish Television and Norway’s NRK into the fuel cell supplier PowerCell has opened a window into the Vestfjord Lofoten hydrogen ferry project that Norway has been building toward for years. The journalists focused on a specific claim about durability. Internal tests suggested that the fuel cells might deliver lifetimes closer to 3,000 hours rather than the roughly 33,000 hours cited in marketing and tender material. Whether that number proves correct or not is almost beside the point. The reporting prompts a larger question. If the propulsion technology at the heart of the project is uncertain, what does that imply for the entire hydrogen system built around it? The Vestfjord ferries are not just vessels. They are part of a tightly coupled chain of ships, hydrogen production, compression, storage, bunkering infrastructure, and operating procedures. If any one link is weak, the system struggles.

Fuel cell durability deserves attention in this context, but it should be understood within the broader evidence on how long fuel cells actually last in real vehicles. Public fleet data show that modern fuel cell systems can operate reliably for many thousands of hours, particularly in light vehicles. Passenger vehicles and taxis typically require far less lifetime operating time, often only 5,000–8,000 hours to match the expected life of the car. Heavy trucks, buses and refuse vehicles, however, require much longer durability targets closer to 25,000–30,000 hours. At present, the data shows that light vehicles, a now dead global market, can have sufficient durability and buses are marginal. Heavy trucks and ferries, however, have no proven reliability measures for their requirements.

In that context a finding of roughly 3,000 hours of durability would be a serious problem for a commercial ferry propulsion system, but it would not be the only challenge facing the Vestfjord project. Even if the fuel cells ultimately approach the longer lifetimes achieved in some bus fleets, the hydrogen ferries still face the larger engineering and economic hurdles of hydrogen production, compression, storage, bunkering infrastructure, and the overall efficiency of the hydrogen energy chain. Fuel cell durability therefore matters, but it sits inside a much larger system whose cost and complexity remain the dominant risks.

Another concern that emerges when looking closely at the Vestfjord propulsion system is the limited public evidence of long-term durability for PowerCell’s marine fuel cells in demanding applications. The company frequently points to its partnership with Bosch as validation of the technology, and Bosch has indeed licensed PowerCell stack designs for its fuel-cell power modules. However Bosch deployments are largely focused on heavy road vehicles and have been delivered mostly into pilot and demonstration fleets rather than large commercial operations with millions of operating hours. PowerCell’s own application history shows a similar pattern of small trials rather than long-lived fleets. Demonstration programs in areas such as hydrogen garbage trucks and other municipal vehicles have struggled to accumulate meaningful operating hours or have been quietly discontinued after pilot phases.

That lack of operational history does not mean the technology cannot work, but it does mean that the Vestfjord ferries are relying on fuel cell systems that have no real-world durability proof points in continuous high-power service. The company’s emphasis on the Bosch relationship helps signal credibility to investors and policymakers, yet Bosch’s deployments themselves remain largely early-stage demonstrations rather than mature fleets that would establish long-term reliability at scale.

Norway is an unusual place to encounter this kind of uncertainty in ferry electrification. The country solved ferry decarbonization once already. In 2015 Norled launched MF Ampere, the first fully electric car ferry operating on a commercial route. Ampere carried 120 vehicles across the Sognefjord using battery propulsion and shore charging. The experiment worked. Within a decade Norway scaled the concept across the country. As of 2025 there are roughly 70 battery electric ferries operating in Norway, with many more hybrid vessels. Operators such as Norled, Torghatten, and Fjord1 built operational experience while shipyards and equipment suppliers refined designs. Costs fell with repetition. Charging systems matured from bespoke engineering into standard products. Norway’s procurement model played a key role. Instead of specifying diesel ferries and hoping for improvements, the government required zero emission solutions and let the industry respond. The result was a platform technology that could be repeated across dozens of routes.

Against that background, the Vestfjord Lofoten hydrogen project stands out as an exception. The route linking Bodø and the Lofoten islands is longer and more exposed than most Norwegian ferry crossings. The direct run from Bodø to Moskenes is about 90 kilometers and typically takes about 3.5 hours. Winter weather is rough. The ferries carry up to 120 vehicles and nearly 600 passengers, making the relatively small roll on roll off passenger vessels. When policymakers looked at the route several years ago they concluded that batteries wouldn’t be viable. Hydrogen appeared attractive. Hydrogen offers high energy density and could in theory support long crossings without massive battery packs. The Vestfjord tender was therefore designed around hydrogen propulsion, with two year round ferries expected to run primarily on hydrogen fuel cells and only partially on backup fuel.

The Vestfjord hydrogen ferry project also sits within a much larger policy context. Norway’s government launched a national hydrogen strategy in 2020 and expanded it in subsequent roadmaps with the explicit goal of building a new export-oriented industrial sector around hydrogen. Policymakers framed hydrogen as a potential successor to parts of the offshore oil and gas economy, using the country’s abundant hydropower and industrial expertise to produce hydrogen and supply emerging European markets. Maritime transport became a central pillar of that strategy. Shipping was viewed as both a domestic demand anchor and a technology showcase that could help Norwegian companies develop fuel cells, hydrogen handling systems, and bunkering infrastructure for global export.

In my earlier analysis of Norway’s hydrogen industrial policy, I argued that this approach reflected a classic industrial development play. Governments often attempt to seed new sectors by creating early domestic demand even when the economics are not yet competitive. The Vestfjord ferries fit squarely into that pattern. They are not simply transport infrastructure. They are intended to demonstrate a complete hydrogen value chain from production to maritime use, with the expectation that the experience gained will support a broader Norwegian hydrogen economy and future export opportunities.

Before the Vestfjord Lofoten project, Norway had already experimented with a hydrogen ferry through Norled’s MF Hydra. Hydra operates on a much shorter route between Hjelmeland and Skipavik and uses onboard hydrogen storage with fuel cells generating electricity for propulsion motors. The project demonstrated that hydrogen propulsion can work technically, but it also exposed the economic and emissions realities of the hydrogen value chain.

In practice the hydrogen was not produced locally. It was trucked roughly 1,300 km from Germany to Norway, adding diesel freight emissions and cost before the fuel even reached the vessel. In my earlier and benefit of the doubt laden analysis of the project, the delivered hydrogen price worked out to about €13–14/kg, resulting in annual fuel costs of roughly €1.4 million. A comparable battery-electric ferry operating the same route would have required less than €100,000 per year in electricity, while a diesel ferry would have burned fuel costing roughly €350,000–400,000 per year. That means hydrogen fuel costs were about four times higher than diesel and roughly fourteen times higher than battery-electric propulsion.

The emissions math was just as stark. Once trucking emissions, liquefaction energy, hydrogen leakage, and German grid electricity were included, the hydrogen ferry’s lifecycle emissions came out around 1,800–2,100 tons CO2e per year. Diesel for the same route was roughly 900 tons CO2e annually. A battery-electric ferry powered by Norway’s grid would have been closer to about 50 tons CO2e. In other words the hydrogen ferry emitted roughly twice as much as diesel and more than thirty times as much as the electric alternative. Hydra showed that hydrogen propulsion can function technically, but it also showed that the fuel supply chain can drive both cost and emissions well above the technologies it is meant to replace.

The Vestfjord hydrogen plan expanded that pilot into a much larger system. The project includes two larger ferries designed to run about 85% of the time on hydrogen. It includes a new hydrogen production plant in Bodø with a 20 MW electrolyzer capable of producing roughly 3,100 tons of hydrogen per year. The hydrogen must then be compressed, stored, and delivered directly to the vessels at the port. Lloyd’s Register describes the ferries as among the largest hydrogen powered vessels ever built. The hydrogen plant itself represents about €85 million in capital cost based on the original estimate of NOK 1 billion. Investors such as Luxcara and the developer GreenH reached a final investment decision in early 2025 with expectations of beginning operations in 2026. When these components are viewed together the Vestfjord solution is no longer a single engineering project. It is a complex system with multiple dependencies.

Schedule risk emerges immediately when examining the timeline. The ferry concession expected service to begin on October 1, 2025. That date passed. Ship deliveries are now described as occurring in 2026. The hydrogen plant reached its final investment decision in January 2025. Major fabrication contracts were awarded in January 2026. The engineering contractor indicates that completion is targeted for the end of 2026, over a year after the ferries were expected to start service. This places the hydrogen plant commissioning almost exactly alongside slipped ferry delivery dates.

Commissioning hydrogen infrastructure is not trivial. Fuel purity must meet strict requirements for fuel cells. Compression and storage equipment must operate reliably. Safety approvals must be obtained. If the ferries arrive before the hydrogen system is fully operational they may have to operate temporarily on backup fuel. That scenario is technically possible because the vessels include biodiesel backup. It also means the project could enter service before delivering the emissions reductions it promises.

Cost risk follows the same pattern. Research on large infrastructure projects shows that bespoke projects tend to run over budget and over schedule. Hydrogen infrastructure fits that pattern. The International Energy Agency reports that electrolyzer systems outside China cost roughly €1,840 to €2,392 per kW installed. Additional equipment such as compression, storage, and bunkering can account for 40% or more of total project cost. Early projects often carry further premiums because supply chains are immature and engineering designs are not standardized. If the Bodø hydrogen facility ultimately costs 25% to 45% more than the original estimate, its capital cost could rise from €85 million to roughly €106 million to €123 million.

Understanding the economics requires separating three different comparisons. The first comparison is electricity input only. The second is delivered energy cost including hydrogen production infrastructure. The third is total lifecycle cost including vessels and infrastructure. These comparisons answer different questions and should not be mixed together.

Start with electricity input only. Public project documentation indicates that the two Vestfjord ferries will consume about 5.5 tons of hydrogen per day combined. That equals about 2,000 tons per year. The Bodø hydrogen plant is described as a 20 MW facility producing up to 3,100 tons per year. Using those numbers, the implied electricity consumption of the plant is about 175 GWh per year.

Multiplying the ferries’ annual hydrogen demand by this electricity intensity yields about 113 GWh of electricity per year required to produce the hydrogen used by the ferries. Using a Norwegian industrial electricity price of about €0.036 per kWh gives an annual electricity cost of roughly €4.0 million for hydrogen production. If ferry service is normalized to roughly 142,000 kilometers per year of direct route equivalent distance, the electricity cost of hydrogen propulsion comes out to roughly €28 per kilometer.

The battery case is simpler. A scaled estimate from existing Norwegian electric ferries suggests that the Vestfjord crossing requires about 24 MWh of usable energy per trip. Under a mainland heavy charging model the two ferries together would require about 43 GWh of electricity per year. At €0.036 per kWh that electricity costs roughly €1.5 million annually. Dividing by the same 142,000 kilometers yields an electricity cost of roughly €11 per kilometer.

On electricity input alone hydrogen is therefore about 2.6 times more expensive than battery propulsion, a multiplier that is usual in comparisons of hydrogen to battery electric drive trains. That difference reflects the physics of the energy chains. Batteries convert electricity to propulsion with relatively small losses. Hydrogen requires electrolysis, compression, storage, and fuel cell conversion before reaching the motor. If other comparisons were in hydrogen’s favor and hydrogen doesn’t dominate costs, this could be a reasonable economic decision.

The second comparison includes the cost of producing hydrogen as a fuel. Hydrogen production requires a dedicated facility with electrolyzers, compression systems, storage tanks, bunkering infrastructure, and operating staff. The Bodø facility has a capital cost estimated at €85 million. Using a 15 year capital recovery period and a 7% cost of capital gives an annualized capital cost of roughly €9.4 million. Dividing this by the plant’s production capacity of 3.1 million kilograms per year yields about €3 per kilogram of hydrogen in capital recovery alone.

Electricity adds roughly €2 per kilogram. Operating and maintenance costs add several euros per kilogram depending on equipment reliability and staffing levels. Real world deployments show how quickly those costs can escalate once hydrogen systems move from modeling into daily operation. In my analysis of California hydrogen stations and the Aberdeen hydrogen bus program, the equipment required constant maintenance, specialized technicians, and frequent component replacement, pushing O&M into ranges equivalent to roughly €3–6/kg of hydrogen in some cases. Those experiences highlight that compression, storage, purification, and fueling systems are not passive infrastructure. They behave more like complex industrial plants that must run continuously in a harsh operating environment. A realistic delivered hydrogen cost range is therefore roughly €7 to €13 per kilogram under early commercial conditions.

At a hydrogen consumption rate of about 14 kilograms per kilometer of ferry service, that delivered hydrogen cost translates to roughly €99 to €182 per kilometer. This number includes electricity, plant capital recovery, and plant operating costs but excludes vessel operating expenses.

The third comparison considers total lifecycle costs. Battery ferries require larger onboard energy storage but much simpler fuel infrastructure. A large electric ferry suitable for the Vestfjord route might cost €32 million to €38 million each depending on battery size and shipyard pricing. Charging infrastructure in Bodø and Moskenes could add roughly €5 million to €12 million depending on power levels and buffer storage. Total propulsion infrastructure would therefore remain below €50 million for the pair of vessels.

Hydrogen propulsion requires both expensive vessels and expensive fuel infrastructure. The hydrogen ferries themselves cost more than battery equivalents because of fuel cell systems and hydrogen storage. Adding the €85 million hydrogen production facility brings total propulsion infrastructure investment for hydrogen close to €150 million or more. If the plant experiences typical first of kind overruns, the total could exceed €180 million.

Over a 15 year concession period the difference accumulates. Hydrogen propulsion carries higher capital cost, higher energy cost, and greater infrastructure complexity. Battery propulsion carries lower energy cost and simpler infrastructure but requires sensible charging architecture to handle grid constraints on the Lofoten islands.

The island of Moskenes illustrates the real engineering constraint in the battery pathway. Statnett reports that new loads above about 1 MW cannot easily be connected in parts of the Lofoten grid without reinforcement. Fast charging a ferry with roughly 24 MWh of energy in a one hour turnaround would require about 24 MW of power, which is incompatible with the present grid connection. But that does not mean batteries are impossible. It means the charging architecture must change. One option concentrates most charging in Bodø where the mainland grid is strong, with ferries carrying larger batteries and recharging primarily there. Another option uses battery buffers at the port so a shore battery charges slowly from the local grid and then delivers high power to the ferry during docking. A third option uses containerized battery modules rolled on and off the vessel, with each 20 foot module storing about 6.25 MWh so that swapping three modules delivers nearly 19 MWh without large instantaneous grid demand. These architectures also became far more plausible over the past few years as battery costs fell and energy density increased.

In my recent assessment on why most maritime battery studies are already obsolete, I showed that many analyses assumed battery costs two to five times higher and energy densities far lower than current systems deliver. Those improvements occurred during the same period that Norway was planning and tendering the Vestfjord hydrogen project, meaning there was a window when policymakers could have revisited the battery option before the hydrogen pathway became locked in. There’s still a sliver of opportunity to avoid the impending economic challenges, although it’s unlikely to be acted upon before things get a lot worse.

Concerns about battery mass and volume often dominate early discussions of electric ferries, but the literature on maritime batteries shows that this constraint has weakened quickly. In my recent review of maritime battery studies, I found that many analyses still assume battery system densities around 80–100 Wh/kg and 100–120 Wh/L, figures typical of marine systems a decade ago. Modern marine battery packs are closer to 140–175 Wh/kg and roughly 150–220 Wh/L at the system level, with containerized solutions reaching about 6.25 MWh per 20-foot module. At those densities a 60 MWh battery installation, large enough for a demanding ferry route like Vestfjorden with mainland-heavy charging, would weigh roughly 350–430 tons and occupy around 270–400 cubic meters.

On a 117 meter ferry designed to carry 120 vehicles and hundreds of passengers, that volume represents a modest fraction of available machinery and vehicle deck space, comparable to the footprint of existing engine rooms, fuel tanks, and auxiliary systems. Recent vessels such as Incat’s large battery electric ferry designs and the growing fleet of Norwegian electric ferries demonstrate that ships can accommodate battery systems of this scale without compromising cargo capacity or stability. In other words, battery mass and volume were once legitimate engineering concerns, but with current battery energy densities they are no longer decisive constraints for ferries in the size class proposed for the Lofoten route.

Norway’s ferry sector has already demonstrated these modular approaches. Modern electric ferries use battery buffers and high power chargers routinely. The supply chain for battery systems and charging infrastructure now spans dozens of vessels. Hydrogen ferry systems remain at an earlier stage of development and require more custom integration.

The Vestfjord Lofoten project illustrates two different project philosophies. Hydrogen represents a bespoke system combining several new technologies that must all succeed simultaneously. Battery ferries represent a modular platform technology already proven across Norway. The PowerCell investigation may turn out to be a limited technical dispute or it may reveal deeper issues with fuel cell durability. Either way the broader engineering question remains. When electricity input, delivered energy cost, and full lifecycle cost are examined separately and rigorously, hydrogen imposes greater complexity and higher costs than the battery solutions Norway has already mastered. This appears to be in service of a hydrogen energy economy which is collapsing globally and which even Norway’s industrial strategy is walking away from.

Norway’s ferry sector earned its reputation by solving practical problems with engineering discipline. The country demonstrated that electrification works when projects are built around repeatable designs and efficient energy systems. The Vestfjord Lofoten hydrogen project departs from that tradition. When it is recognized as economically unsupportable and is converted to battery electric is just a matter of time.
