Fuel cell electric vehicles
FCVs have a higher fuel cost compared to gasoline vehicles due to hydrogen's unique physical properties. In California, hydrogen has retailed for approximately $14.00 per kilogram, which is equivalent to $14 per gallon of gasoline. This makes the fuel cost per mile for FCVs three times higher than gasoline hybrids and twice that of conventional gasoline vehicles.
However, advocates of hydrogen fuel argue that the high fuel economy of FCVs helps keep fuelling costs competitive with gasoline-powered vehicles. They also predict that future hydrogen fuel costs will be lower due to increased production volume or greater economies of scale.
The cost of hydrogen fuel per mile can be compared to that of gasoline using historical price data. For example, in 2021, hydrogen retailed at $16.50 per kilogram, which needed to be $5.88 per kilogram to be competitive with hybrid gasoline vehicles on a per-mile basis.
The levelized cost of driving FCVs includes initial vehicle costs, fuel costs, and, if applicable, residential charger equipment and installation. It does not include other operational or maintenance costs beyond fuel and insurance.

Hydrogen storage tank costs
The cost of a hydrogen storage tank is dependent on several factors, including the size of the tank and the level of production. For example, a 1 kg tank costs $1,400 initially, $1,200 to replace, and $30 per year for operation and maintenance. These costs can be calculated for different tank sizes to determine the optimal system.
Estimates of hydrogen storage vessel costs are based on assumptions of low production volume, which is expected to increase gradually to high production volume by 2050. This increase in production volume is anticipated to drive down costs and make fuel cell technology more appealing, especially in developing countries.
The cost of a hydrogen storage tank is also influenced by the variability of current hydrogen prices. As hydrogen prices fluctuate, the modelled costs are used as a baseline for fuel cell electric vehicles rather than the current market costs. This approach helps to distinguish the effects of fuel prices from vehicle technology advancements.
Currently, fuel cell electric vehicles are manufactured at low production volumes and are available for purchase or lease in the US. The lease of a fuel cell electric vehicle often includes access to free hydrogen fuel for a limited period, highlighting the importance of considering both the vehicle and fuel costs when evaluating the overall expenses.

Maintenance and resale value
Fuel cell stacks have gained popularity as an alternative to fossil fuel-based generators and engines. They offer superior efficiency, greater adaptability, and zero emissions. The cost of a fuel cell stack varies depending on its application and power output. For example, a PEM Fuel Cell used for educational purposes can be purchased for as little as $60, while a 100W fuel cell stack suitable for powering small motorboats or for laboratory research can cost around $2,1000. More powerful fuel cells designed for telecommunications or vehicles can range from $9,000 to over $20,000. Custom-configured fuel cells for industry-specific equipment can start at $200,000.
The United States government supports the development of fuel cell technology through various initiatives, recognizing its potential to reduce dependence on foreign energy sources and improve environmental conditions. The Federal Government provides monetary contributions for research and development, and programs such as the Climate Change Fuel Cell program offer cost-sharing incentives for the purchase of fuel cell systems. These efforts contribute to the commercialization of fuel cell technology and make it more accessible and affordable for consumers.
The true cost of a fuel cell stack involves considering a range of factors beyond the initial purchase price. These include maintenance costs, the price of hydrogen fuel, operating conditions, and long-term savings. By taking into account the complete lifecycle of the system, consumers can make informed decisions about the true value and affordability of fuel cell stacks compared to other energy generation systems.
In summary, while fuel cell stacks may have a higher upfront cost, their long lifespan, low maintenance requirements, and high resale value contribute to a lower overall cost of ownership over time. Additionally, government incentives and the potential for long-term savings make fuel cell stacks a compelling option for those seeking efficient, adaptable, and environmentally friendly energy solutions.

Hydrogen availability
Hydrogen is a clean fuel that can be produced from a variety of sources, including natural gas, nuclear power, biomass, solar power, and wind. Hydrogen can be used in industrial processes, as rocket fuel, and in fuel cells for electricity generation and powering vehicles. Hydrogen fuel cells generate electricity through a chemical reaction between hydrogen and oxygen, with water vapour being the only emission.
Hydrogen fuel cells are an efficient power source for trucks, construction equipment, buses, and industrial or marine applications. They offer a high energy-to-weight ratio, quick refuelling, and a longer range than most battery-electric vehicles. Hydrogen fuel cells are also more efficient than traditional internal combustion engines, as they convert chemical energy directly into electrical energy, reducing energy loss from heat.
The availability of hydrogen for fuel cells is increasing as the use of hydrogen in the transportation and infrastructure industries accelerates. Fuel cell and engine technologies that are practical for use in commercial transport systems and infrastructure are now advancing, and the rollout of hydrogen production and refueling infrastructure is expected to speed up in the coming years.
Hydrogen liquefaction and cryogenic liquid storage is an energy-intensive and expensive process, but it allows for the storage and transportation of hydrogen for use in fuel cell vehicles or directly as fuel in truck, rail, marine, and rocket engines. NASA, for example, has the two largest liquid hydrogen storage tanks in the world. Hydrogen could also facilitate the decarbonization of the electric power sector by storing energy produced through renewable sources for later use when demand is high.

Government subsidies
The cost of fuel cells varies depending on the specific application and scale. Fuel cell electric vehicles (FCEVs), for instance, are available for purchase or lease in the US for approximately $58,300, or $379-$389 per month. This often includes access to free hydrogen fuel for up to 3 years or $13,000-$15,000.
To promote the adoption of fuel cells, governments worldwide have implemented various subsidies and incentives. These can be categorized into single-stage and two-stage subsidies, with the former remaining unchanged over time, and the latter changing over a specific period. Here are some examples of government subsidies:
- United States: The US Department of Energy Hydrogen and Fuel Cell Technologies Office (HFTO) offers grants of up to $10 million for research, development, demonstration, and deployment of affordable clean-hydrogen technologies. The US Environmental Protection Agency (EPA) also provides funding for zero-emission port equipment or technology through the Clean Ports Program. The Inflation Reduction Act of 2022 includes clean energy tax credits and provisions that encourage domestic renewable energy production, with a focus on clean hydrogen and fuel cell technologies.
- China: The Chinese government has promoted the use of new-energy vehicles through financial subsidies and tax incentives. A study on the effects of government subsidies on heavy-duty hydrogen fuel cell truck penetration found that acquisition subsidies were the most impactful, followed by refueling station construction subsidies, and R&D subsidies.
- Other Initiatives: The Hydrogen Shot, established within the US Department of Energy's Energy Earthshots Initiative, aims to reduce the cost of clean hydrogen by 80% to $1 per kilogram in a decade. It funds hydrogen demonstration projects that lower costs, reduce emissions, create jobs, and benefit disadvantaged communities. Additionally, the US Department of Energy's Loan Programs Office (LPO) offers loans for innovative vehicle technology projects, including hydrogen fuel cell technology.
These government subsidies and initiatives play a crucial role in accelerating the development and adoption of fuel cell technologies, reducing costs, and transitioning towards cleaner energy sources.
