Hydrogen fuel cell cars are a type of zero-emission vehicle that only emits water vapour. They are powered by an electric motor and are therefore classified as e-cars. Hydrogen fuel cell cars have been available for purchase since 2015, with models including the Honda Clarity Fuel Cell, the Hyundai Nexo SUV, and the Toyota Mirai. However, their widespread adoption has been hindered by the lack of hydrogen refuelling infrastructure outside of California. Despite this, hydrogen fuel cell cars offer several advantages, such as zero emissions, high efficiency, and fast refuelling times.

What You'll Learn
Hydrogen fuel cell cars are zero-emission vehicles
The process that takes place in a fuel cell is known as reverse electrolysis. Hydrogen reacts with oxygen in the process, with the hydrogen coming from tanks in the car and the oxygen from the ambient air. The only things this reaction produces are electrical energy, heat, and water, which exits as water vapour through the exhaust. The electricity generated in the fuel cell flows to the electric motor and directly drives the vehicle, and/or charges a battery that acts as temporary storage until the energy is needed for driving. This "buffer" battery is significantly smaller and lighter than the battery of an all-electric car and is constantly recharged by the fuel cell.
Hydrogen fuel cell cars are also able to recover braking energy. In this process, the electric motor converts the car's kinetic energy back into electrical energy and feeds it into the buffer battery. Hydrogen fuel cell cars are quiet, very energy-efficient, and have a similar range and performance to gasoline-powered cars. They can carry enough hydrogen fuel for 300-400 miles of range and their tanks can be refuelled as quickly as a standard car's gas tank. However, hydrogen fuel cell cars are currently much rarer than electric vehicles. As of mid-2022, there were 17,000 or fewer hydrogen-powered vehicles on US roads, all of them in California, the only state with a network of retail hydrogen fuelling stations.
BMW is convinced that hydrogen can make an important contribution to sustainable mobility, but this depends on the availability of hydrogen infrastructure and a favourable hydrogen price. A kilogram of hydrogen currently costs around 14 euros, but if hydrogen production increases worldwide, the price per kilogram in Germany could fall to 4-6 euros by 2030.

They are powered by an electric motor
Hydrogen fuel cell cars are powered by an electric motor, which draws its energy from a fuel cell stack. This stack combines oxygen and hydrogen to generate electricity and power the car. The hydrogen is stored in carbon-fiber-reinforced tanks and the electricity generated powers the electric motor. This process is called reverse electrolysis, where hydrogen reacts with oxygen to produce electrical energy, heat, and water vapour. The electricity generated powers the electric motor directly or charges a battery that acts as a temporary store of energy for the motor. This buffer battery is smaller and lighter than the battery of a battery-electric car.
Hydrogen fuel cell cars are therefore classified as e-cars or FCEVs (Fuel Cell Electric Vehicles). They are distinct from BEVs (Battery Electric Vehicles) in that they produce their own electricity, rather than drawing it from a built-in battery. This means that hydrogen cars do not need to be plugged in to an external power source to recharge. The electricity is generated onboard the vehicle, in the fuel cell, which acts as a power plant.
Hydrogen fuel cell cars are zero-emission vehicles, with water vapour as their only waste product. They are also very energy-efficient, quiet, and have a similar range to their gasoline counterparts. They can be refuelled in a similar way to a traditional car, at a hydrogen refuelling station, and can be refuelled as quickly as a standard car.
While hydrogen fuel cell cars have been available since 2015, with models such as the Honda Clarity Fuel Cell, the Hyundai Nexo SUV, and the Toyota Mirai, their roll-out has been limited by the lack of hydrogen refuelling infrastructure. As of 2024, there are fewer than 100 publicly accessible hydrogen filling stations in the US, the majority of which are in California. This means that, at present, hydrogen cars are only a viable option for those living in California. However, there are plans to expand the infrastructure for hydrogen refuelling stations, and some car companies are offering free fuelling and other incentives to reduce the cost of ownership.

Hydrogen fuel cell vehicles are eligible for rebates and incentives
Hydrogen fuel cell vehicles are a type of zero-emission vehicle that uses hydrogen to generate electricity and power the electric motor. These vehicles are eligible for various rebates and incentives, which can make them more affordable and accessible to consumers.
In the United States, the Department of Energy offers financial incentives for hydrogen and fuel cell projects. The Inflation Reduction Act of 2022 (IRA) includes clean energy tax credits and provisions that encourage the development of domestic renewable energy sources. The IRA extends and increases federal tax credits for clean hydrogen and fuel cell technologies, such as the Advanced Energy Project Credit. These tax credits can help reduce the cost of purchasing and owning a hydrogen fuel cell vehicle.
Additionally, specific states and regions may offer their own incentives for hydrogen fuel cell vehicles. For example, California, which is the only state with a network of retail hydrogen fueling stations, offers a $4,500 rebate for fuel cell cars from the Clean Vehicle Rebate Project. This rebate increases to $7,500 for income-qualified purchasers. California also offers additional perks, such as the Clean Air Vehicle decal, which allows solo driving in carpool lanes, and programs supporting clean transportation ownership in low-income and disadvantaged communities.
Hydrogen fuel cell vehicles are also eligible for incentives in other countries. For instance, Germany has the Clean Energy Partnership initiative, which includes companies like BMW, working to expand the infrastructure for hydrogen fueling stations. The availability of these incentives can vary by region, so it is essential to check for specific programs and eligibility requirements in your area.
These rebates and incentives for hydrogen fuel cell vehicles demonstrate the support and encouragement for the adoption of this clean energy technology. They can help make hydrogen fuel cell vehicles more affordable and accessible to consumers, contributing to the reduction of carbon emissions from transportation.

Hydrogen fuel cell cars are easy to maintain
The Hyundai Nexo, one of the hydrogen fuel cell vehicles currently on sale in the U.S., comes with three years or 36,000 miles of factory-scheduled maintenance for free, which includes tire rotations, multi-point inspections, and more. The Toyota Mirai, the other hydrogen fuel cell vehicle currently on sale in the U.S., comes with three years or 35,000 miles of complimentary Extended ToyotaCare coverage.
In addition to being easy to maintain, hydrogen fuel cell cars are also quick and easy to refuel. They can typically be refueled in just five minutes, and this will provide enough fuel for another 300 to 400-mile stint. This is a significant advantage over electric vehicles, which can take a long time to recharge.

Hydrogen refuelling infrastructure is lacking outside of California
Hydrogen fuel cell vehicles (HFCVs) are a type of zero-emission vehicle that runs on electricity produced by combining hydrogen and oxygen in a fuel cell. While HFCVs are rare, with only about 17,000 on US roads as of mid-2022, their limited availability is not due to a lack of interest from car manufacturers. Honda, Hyundai, and Toyota have all offered hydrogen-powered cars for sale, and Honda is set to release a new hydrogen vehicle, the Honda CR-V e:FCEV, in 2024. However, the lack of hydrogen refuelling infrastructure outside of California has significantly hindered the adoption of HFCVs.
California has actively promoted the commercialisation of hydrogen and fuel cell technology through initiatives like the California Hydrogen Business Council (CHBC) and the Clean Vehicle Rebate Project. The state also has a network of retail hydrogen fuelling stations that support the growing number of HFCVs on its roads. This infrastructure is essential because HFCV drivers refill their vehicles at dedicated hydrogen fuelling stations, which are designed similarly to traditional gas stations.
Outside of California, the hydrogen refuelling infrastructure is much less developed. As a result, HFCVs are currently impractical for most consumers in other states. While there are efforts to expand hydrogen refuelling infrastructure worldwide, California remains the leader in this regard. The state's Energy Commission is investing in an initial network of 100 public hydrogen stations to support the existing fuel cell electric cars and encourage the adoption of zero-emission vehicles.
The lack of hydrogen refuelling infrastructure outside of California is a significant barrier to the widespread adoption of HFCVs in the US. However, it is important to note that the infrastructure is expanding, and initiatives like California's can play a crucial role in making HFCVs a more viable option for consumers in the future.
