Hydrogen is the most abundant element in the Universe. It is found on Earth in large quantities, combined with other elements (carbon, oxygen, etc.). It is therefore necessary to extract it to obtain this gas with multiple applications. We thus refer to it as an energy carrier like electricity.

Hydrogen has very interesting energy properties. The calorific value by mass of hydrogen is the highest of all existing fuels. On an equivalent mass basis, more than twice as much as petrol and natural gas and three times as much as diesel.

The hydrogen fuel cell vehicle is an electric vehicle. The fuel cell in the vehicle produces electricity and recoverable heat directly, with water as the only waste product! The fuel cell on board the vehicle is supplied by a tank of gaseous hydrogen.
