Hydrogen fuel-cell vehicles (HFCVs) are powered by an electric motor, but instead of a large, heavy battery, they are powered by a fuel-cell stack where hydrogen combines with oxygen from the air to produce electricity. This makes them a type of zero-emission vehicle, with water vapour as the only waste product. Hydrogen fuel cell cars can go 300-400 miles on a full tank of hydrogen, which can be refuelled in 3 to 5 minutes at a hydrogen fuelling station. While hydrogen is more expensive than gasoline, fuel cells are more efficient, and many car manufacturers include three years' worth of free fuel with a vehicle.

Hydrogen fuel cell vehicles (HFCV) are zero-emission vehicles that emit only water vapour
Hydrogen fuel cell vehicles (HFCV) are powered by hydrogen and use an electric motor to turn their wheels, instead of an internal combustion engine. This makes them zero-emission vehicles, with no harmful tailpipe emissions, and only water vapour and warm air emitted from the exhaust.
HFCVs are similar to electric vehicles (EVs) in many ways, but there are some key differences. HFCVs are powered by hydrogen, which combines with oxygen from the air in a chemical reaction, to generate electricity. EVs, on the other hand, are charged directly to a battery. The process of fuelling an HFCV is much faster than charging an EV, taking only 3-5 minutes, or up to 10 minutes, compared to half an hour for fast charging an EV. HFCVs can travel up to 500km without refuelling and future ranges are expected to increase to 600-700km.
HFCVs are also similar to EVs in that they are both smooth, quiet, and peaceful to drive. However, unlike EVs, HFCVs do not suffer from long charging times. HFCVs also have high-voltage battery packs and one or more armoured, carbon-fibre tanks to hold hydrogen under extremely high pressure.
In the US, as of mid-2022, there were 17,000 or fewer hydrogen-powered vehicles on the roads, all of them in California, which has a network of retail hydrogen fuelling stations. The Honda Clarity Fuel Cell, Hyundai Nexo SUV, and Toyota Mirai have been offered for sale, but Honda has now ended production of the Clarity, and Hyundai has sold only about 1600 Nexo SUVs in six years. HFCVs are currently more expensive than comparable EVs or internal combustion engine vehicles, due to low production volumes and the demand for platinum, a catalyst in electricity generation. However, the amount of platinum needed has been reduced, and recycled platinum is also being used.

Hydrogen is the most common element in the universe and is among the cleanest and greenest fuels for powering cars
Hydrogen is the most common element in the universe. It is also among the cleanest and greenest fuels for powering cars. This is because hydrogen fuel-cell vehicles (HFCVs) emit only water vapour and heat when in use, with no harmful emissions.
Hydrogen fuel-cell vehicles use the same type of electric motor as battery-electric cars. However, instead of being powered by a large, heavy battery, they are powered by a fuel-cell stack. In this stack, pure hydrogen passes through a membrane to combine with oxygen from the air, producing electricity and water vapour. Hydrogen vehicles can also recover braking energy, converting the car's kinetic energy back into electrical energy and feeding it into a buffer battery. This means that, unlike electric cars, hydrogen cars produce their own electricity and do not need to be charged from an external power source.
While hydrogen cars are more expensive than comparable electric vehicles or internal combustion engine cars, they have a similar five-minute refuelling time to traditional gas-powered cars. Hydrogen is also one of the most efficient ways to store and transport renewable energy, and it is hoped that the expansion of hydrogen refuelling infrastructure will help to drive down costs.
As of mid-2022, there were around 17,000 hydrogen-powered vehicles on US roads, all of which were in California, the only state with a network of retail hydrogen fuelling stations. However, hydrogen vehicles are expected to become more common in the future, with major manufacturers focusing on making electric vehicles dominant by 2030.

Hydrogen fuel cell cars are powered by an electric motor and are classified as e-cars
Hydrogen fuel cell cars are technically a series hybrid, which is why they are sometimes classified as fuel-cell hybrid electric vehicles (FCHEV). Hydrogen fuel cell cars are different from electric vehicles (EVs) as they produce their own electricity. This means their power does not come from a built-in battery, as is the case with purely electric vehicles or plug-in hybrid vehicles, which can be charged from an external power source.
The process by which hydrogen fuel cell cars produce electricity is known as reverse electrolysis. This process takes place in a fuel cell, where hydrogen reacts with oxygen to produce electrical energy, heat, and water vapour. The electricity generated in the fuel cell can either flow to the electric motor and directly drive the vehicle, or it can charge 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. Hydrogen fuel cell cars can also recover or "recuperate" braking energy, a process known as regenerative braking.
Despite the potential of hydrogen fuel cell cars, they are currently much rarer than EVs. 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. The high cost of creating a brand-new fuelling network from scratch has proven to be a significant challenge for the commercialisation of hydrogen fuel cell cars. Additionally, the fuel is much pricier for drivers than gasoline or electricity. However, studies have shown that an infrastructure with electric charging and hydrogen refuelling stations is cheaper overall than a pure electric charging infrastructure. Vehicle manufacturers such as BMW have joined initiatives like the Clean Energy Partnership to drive the development of hydrogen fuelling infrastructure.

Hydrogen fuel cell cars can be refuelled in 3 to 5 minutes at hydrogen fuelling stations
Hydrogen fuel cell cars are an exciting new technology that uses hydrogen, the most abundant element in the universe, as an energy carrier to power vehicles. These cars are similar to electric vehicles (EVs) in many ways but differ in how they store energy. Hydrogen fuel cell cars produce electricity by combining hydrogen and oxygen in a fuel cell stack, resulting in water vapour and electricity, which powers the car's electric motor. This technology offers several advantages over traditional EVs, including a shorter refuelling time.
One of the most significant benefits of hydrogen fuel cell cars is their quick refuelling process, which takes only 3 to 5 minutes at hydrogen fuelling stations. This is comparable to refuelling a standard car with gasoline and is significantly faster than charging an EV battery. The refuelling process for a hydrogen fuel cell car is also straightforward and user-friendly. The hydrogen pump and communicator are secured in a locked box, protecting them from the elements and preventing drips or messes. The pump's tight grip on the receiver allows drivers to relax during the refuelling process without needing to hold the pump.
However, it is important to note that the availability of hydrogen fuelling stations is currently limited. While hydrogen fuelling infrastructure is expanding worldwide, the number of stations in some regions, such as California, has fallen short of expectations. As a result, drivers of hydrogen fuel cell cars may need to plan their refuelling stops carefully and may encounter higher prices due to the limited supply of hydrogen fuel. Nevertheless, initiatives like the California Hydrogen Business Council (CHBC) and collaborations between vehicle manufacturers, hydrogen producers, and filling station operators are working to address these challenges and increase the accessibility of hydrogen fuelling.
In summary, hydrogen fuel cell cars offer a convenient and efficient refuelling experience, with a process that takes just 3 to 5 minutes at hydrogen fuelling stations. While the limited availability of these stations can be a challenge, ongoing efforts to expand the infrastructure and the environmental benefits of hydrogen fuel cell technology show promising potential for the future of transportation.

Hydrogen fuel cell cars qualify for consumer incentives such as federal income tax credits and access to carpool lanes
Hydrogen fuel cell cars are a rare sight on US roads, with only 17,000 or fewer in the country as of mid-2022. However, they are an attractive prospect for those seeking a zero-emissions vehicle, as they emit only water vapour. They are also powered by an electric motor, and so are classified as e-cars.
The main difference between hydrogen fuel cell cars and other electric vehicles is that hydrogen vehicles produce their own electricity. They do this by using a fuel-cell stack in which pure hydrogen passes through a membrane to combine with oxygen from the air, generating electricity. This means that hydrogen cars do not need to rely on a built-in battery or an external power source.
As hydrogen fuel cell technology is in its infancy, these vehicles are currently more expensive than comparable e-cars with batteries or internal combustion engines. However, hydrogen fuel cell cars qualify for consumer incentives such as federal income tax credits and access to carpool lanes.
In the US, federal income tax credits of up to $7,500 are available for new plug-in hybrid, all-electric, and fuel cell electric vehicles purchased in 2023 or later. Pre-owned vehicles purchased on or after 1 January 2023 may be eligible for a federal income tax credit of 30% of the sale price, up to a maximum of $4,000. These credits can be transferred to the dealer so that they can be applied to the final purchase cost, and the dealer will be reimbursed by the IRS.
In California, the sole state with a network of retail hydrogen fuelling stations, there are additional incentives for hydrogen fuel cell cars. The California Hydrogen Business Council (CHBC) is an advocacy group of over 100 companies and agencies working to advance the commercialisation of hydrogen and fuel cell technology.
