FAQ About Hydrogen Vehicles

Hydrogen fuel is much more efficient than gasoline, but it's also more expensive.

In the event of a hydrogen leak, the gas simply dissipates harmlessly. Moreover, the tanks that contain H2 are thick walled and carefully designed to prevent leaking, even after a substantial crash.

Ideally, a hydrogen fuel-cell vehicle has no environmental impact. Energy is produced by combining hydrogen with oxygen pulled from the atmosphere, and the tailpipe emission is water.

Hydrogen has a wide flammability range in comparison with all other fuels. As a result, hydrogen can be combusted in an internal combustion engine over a wide range of fuel-air mixtures. A significant advantage of this is that hydrogen can run on a lean mixture.

If the electricity comes from renewable sources, the hydrogen fuel is considered to be renewable or “green” because it is produced without CO2 emissions.

Hydrogen fuel cell vehicles, which use electric motors, are much more energy efficient and use 40-60 percent of the fuel's energy — corresponding to more than a 50% reduction in fuel consumption, compared to a conventional vehicle with a gasoline internal combustion engine.

Like all-electric vehicles, fuel cell electric vehicles (FCEVs) use electricity to power an electric motor.

Because hydrogen doesn't occur naturally, it has to be extracted, then compressed in fuel tanks. It then has to mix with oxygen in a fuel cell stack to create electricity to power the car's motors. It can be expected that hydrogen cars replacing EVs and that's true to an extent, but hydrogen-powered cars are not expected to replace EVs soon. With the developing technology, we can observe this in the future.

An electric car is powered by a lithium-ion battery, which supplies power to a motor to power the various parts of the vehicle. Hydrogen fuel cell cars, also known as fuel cell electric vehicles, are refuelled with hydrogen at specific service stations that contain pressurised tanks of the natural gas.

Depending on the model, a hydrogen car can travel around 300-400 miles on a single tank of fuel.

Currently, there are a limited number of hydrogen refueling stations available, but the number is growing. You can find a map of hydrogen refueling stations on the Department of Energy's Alternative Fuels Data Center website.

Hydrogen cars are currently more expensive than gas-powered cars, but the cost is expected to come down as production increases. Additionally, the cost of hydrogen fuel is currently higher than gasoline, but this is also expected to decrease as the infrastructure grows.

Some states offer incentives for purchasing a hydrogen car, such as tax credits or rebates. Additionally, some automakers may offer incentives, such as free hydrogen fuel for a period of time.

Yes, hydrogen can be produced using renewable energy sources, such as wind or solar power. This is known as "green hydrogen."

Hydrogen is a flammable gas, but it can be transported safely in pressurized tanks. Additionally, hydrogen fuel cell vehicles have been extensively tested for safety and have passed crash tests with flying colors.

The environmental impact of producing hydrogen fuel depends on the method of production. If the hydrogen is produced using renewable energy sources, then the environmental impact is minimal. However, if it is produced using fossil fuels, then the environmental impact can be significant.

The driving experience of a hydrogen car is similar to that of a gas-powered car, with the exception of the lack of engine noise. Additionally, hydrogen cars have instant torque, which provides a smooth and responsive driving experience.
