FAQ About Hydrogen Vehicles
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.
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.
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.
