What is "hydrogen"?
Hydrogen is a fuel used in some vehicles, mainly in fuel cell cars, where it combines with oxygen to produce electricity, powering the motor while only releasing water as a byproduct. It is stored in high-pressure tanks and refueled at special stations. Hydrogen is seen as a clean alternative to gasoline or diesel, but its availability is limited, and producing it in an environmentally friendly way remains a challenge.
Examples
Hydrogen fuel cells convert hydrogen into electricity to power electric vehicles.
