Introduction to Hydrogen Fuel

Hydrogen fuel refers to liquid hydrogen fuel. Burning one gram of hydrogen can release 142 kilojoules of heat, three times that of gasoline. The product of its combustion is water, without ash and waste gas, and will not pollute the environment.
The French rail transit construction giant Alstom announced on November 9 that the world's first hydrogen-powered train produced by them will officially start running in Germany in 2021.
