Solution - Liquid hydrogen is the fuel used in rockets

Hydrogen gas has the highest calorific value that is150 kJ/kg.

It is a powerful rocket propellant, as it has the lowest molecular weight and it burns with extreme intensity.

It can be stored in large quantities in small spaces because it is very lightweight.
