Hydrogen fuel cell cars are vehicles that use hydrogen to generate electricity and power their electric motors. They are a type of zero-emission vehicle, with water vapour as their only waste product. Hydrogen fuel cell technology has been around for decades, but its application in cars is relatively new. As of 2024, there were 53 publicly accessible hydrogen refuelling stations in the US, 52 of which were in California. In 2023, 3,143 hydrogen cars were sold in the US, compared to 380,000 battery-electric vehicles. However, hydrogen cars are making inroads, and there are new developments in the hydrogen fuel cell car market.

Hydrogen fuel cell cars are zero-emissions vehicles, only emitting water vapour
Hydrogen fuel cell cars are zero-emissions vehicles that only emit water vapour. This is because hydrogen fuel cell cars are powered by an electric motor, but unlike battery-powered or plug-in hybrid cars, they produce their own electricity. Hydrogen fuel cell cars use compressed hydrogen gas that feeds into an onboard fuel cell stack, which transforms the fuel's chemical energy into electrical energy. This electricity then powers the car's electric motors. The byproduct of this reaction is water vapour, which is emitted through the exhaust.
The process that takes place in a fuel cell is known as reverse electrolysis, where hydrogen reacts with oxygen to produce electrical energy, heat, and water. The hydrogen is stored in gaseous form in thick-walled tanks, which are safe and have been validated by numerous crash tests. The electricity generated in the fuel cell can either flow directly to the electric motor or charge a battery that acts as a temporary store until the energy is needed for the drive. This "buffer" battery is significantly smaller and lighter than the battery of an all-electric car.
While hydrogen fuel cell cars are a type of zero-emission vehicle, there are some challenges to their widespread adoption. As of 2024, there were only 53 publicly accessible hydrogen refuelling stations in the US, 52 of which were in California. The high cost of building a nationwide network of hydrogen refuelling stations has been cited as a barrier to the commercialisation of hydrogen fuel cell cars. Additionally, hydrogen fuel cells are relatively expensive to produce as their designs require rare substances such as platinum as a catalyst.
Despite these challenges, there are some incentives and initiatives in place to promote the adoption of hydrogen fuel cell cars. In California, fuel cell cars are eligible for a rebate from the Clean Vehicle Rebate Project and can qualify for the Clean Air Vehicle decal to drive solo in the carpool lanes. California is also spending over $2.5 billion in clean energy funds to accelerate the sales of hydrogen and battery vehicles, including plans to build 200 hydrogen stations by 2025. Vehicle manufacturers such as BMW have also joined forces with hydrogen producers and filling station operators to drive the expansion of hydrogen infrastructure.
While the future of hydrogen fuel cell cars is uncertain, they offer a green transportation alternative with the potential to reduce greenhouse gas emissions. With advancements in technology and infrastructure, hydrogen fuel cell cars may become a more viable option in the years to come.

Hydrogen fuel cell vehicles use an electric motor, but are powered by hydrogen, not a large battery
Hydrogen fuel cell vehicles (HFCVs) use an electric motor, but unlike battery-electric vehicles, they are powered by hydrogen, not a large battery. HFCVs use a fuel cell stack in which hydrogen passes through a membrane to combine with oxygen from the air, producing electricity to turn the wheels, as well as water vapour. This process is known as reverse electrolysis.
HFCVs are zero-emission vehicles, with the only waste produced being pure water vapour. They are also very energy-efficient and quiet, with a similar range and performance to their gasoline counterparts. However, they are much rarer than electric vehicles, with only around 17,000 on US roads as of mid-2022.
One of the main challenges for HFCVs is the lack of infrastructure for refuelling. Creating a new network of hydrogen fuelling stations has proven to be expensive and unreliable, and the fuel is currently much pricier than gasoline or electricity. As a result, critics argue that hydrogen cars are unlikely to be widely adopted in the next few decades and are a dangerous distraction from more readily available solutions for reducing the use of fossil fuels in vehicles.
However, some incentives exist to encourage the use of HFCVs. For example, in California, HFCVs are eligible for a rebate of up to $7,500 from the Clean Vehicle Rebate Project and can use carpool lanes with a Clean Air Vehicle decal. Additionally, hydrogen fuel cell technology is not new and has been tried and tested in other industries, such as refineries.

Hydrogen fuel cell cars are eligible for a rebate from California's Clean Vehicle Rebate Project
Hydrogen fuel cell cars are eligible for rebates from California's Clean Vehicle Rebate Project (CVRP). The CVRP offered rebates of up to $7,500 for the purchase or lease of a new fuel cell electric vehicle (FCEV). However, as of November 8, 2023, the CVRP is closed.
California has been at the forefront of hydrogen fuel cell vehicle adoption, with almost all of the 17,000 or fewer hydrogen-powered vehicles in the US located in the state as of mid-2022. This is due in part to California being the only state with a network of retail hydrogen fuelling stations. However, the rollout of hydrogen fuelling infrastructure has faced challenges, with high costs and reliability issues. As of 2024, there were 52 publicly accessible hydrogen refuelling stations in California, compared to 65,000 electric charging stations.
Despite these challenges, California continues to promote the adoption of hydrogen fuel cell vehicles through various initiatives. The state has established safety protocols for handling hydrogen vehicles and their components, including rules for draining hydrogen tanks and purging the system of any remaining fuel. Additionally, California has implemented programs such as the Drive Clean! Rebate Program, which provides rebates of up to $3,000 for the purchase or lease of eligible new hydrogen fuel cell vehicles.
The benefits of hydrogen fuel cell vehicles include zero emissions and the ability to produce electricity on-board, eliminating the need for large, heavy batteries. However, critics argue that the widespread adoption of hydrogen-powered vehicles is unlikely in the near future due to the high cost and infrastructure requirements. Nevertheless, transportation experts remain hopeful for the technology, highlighting its potential as an emission-free alternative without lengthy charging times.

Hydrogen fuel cells are expensive to produce, requiring rare substances like platinum
Hydrogen fuel cell vehicles (FCVs) are zero-emission vehicles that use an electric motor powered by a fuel cell stack. Pure hydrogen passes through a membrane in the fuel cell to combine with oxygen from the air, producing electricity and water vapour. This electricity then turns the wheels.
While hydrogen fuel cells are an exciting prospect, they are relatively expensive to produce. This is because their design requires rare substances, such as platinum, as a catalyst. In 2014, it was estimated that Toyota would lose about $100,000 on each Mirai sold due to these production costs. However, hydrogen fuel cell advocates argue that FCVs' high fuel economy will keep FCV fuelling costs competitive with gasoline-fuelled vehicles.
The high cost of hydrogen fuel is due to its unique physical properties. Hydrogen is also highly flammable, which has led to strict safety protocols and expensive, specialised fuelling infrastructure. This, in turn, has made it difficult for hydrogen fuelling stations to be built and operated, further increasing the cost of hydrogen fuel.
Despite these challenges, experts suggest that within ten years, hydrogen fuel will be cost-competitive with traditional fuel sources. This is because the costs for renewable energy sources used for green hydrogen production are falling, and governments are expected to offer subsidies to incentivise clean energy growth. In addition, the price of green hydrogen continues to fall, and major oil producers are making decarbonisation commitments that will likely raise gasoline and diesel prices.

Hydrogen fuel cell cars are available for sale or lease from major automakers
As of 2024, there were only 53 publicly accessible hydrogen refuelling stations in the US, 52 of which were located in California. This lack of infrastructure is a significant barrier to the widespread adoption of hydrogen fuel cell cars. The process of refuelling a hydrogen car can also be more complex and time-consuming than refuelling a traditional petrol or diesel car.
Despite these challenges, some automakers have begun to offer hydrogen fuel cell cars for sale or lease. Toyota, for example, has sold roughly 14,300 Mirai sedans in the US, although this has involved substantial discounting at times. Honda has also entered the market with its CR-V e:FCEV, an adaptation of its popular compact crossover. However, this vehicle is only available for lease and only in California, with a projected volume of 300 vehicles per year.
While hydrogen fuel cell cars may have some advantages over traditional petrol or diesel cars, they also face several challenges, including high production and fuel costs, limited refuelling infrastructure, and complex refuelling processes. It remains to be seen whether these challenges can be overcome to make hydrogen fuel cell cars a more viable option for consumers.
