Hydrogen engine
A hydrogen engine is a device that transforms the chemical energy contained in dihydrogen (H2) into mechanical energy.
There are three types of hydrogen engines:
- A reaction engine;
- An internal combustion engine;
- An electric engine powered by a fuel cell.
Hydrogen engines are used in astronautics, aeronautics and the car industry.
