A
Production of fuel gases

B
Manufacture of ammonia and methanol

C
Conversion of unsaturated to saturated oils

D
Rocket fuel and fuel cells

Hydrogen is used as fuel so that there is very less emission of harmful gases. Haber's process is used to prepare ammonia by combining atmospheric nitrogen and hydrogen. Hydrogen is also used in the production of methanol. Unsaturated compounds are saturated by replacing the double/triple bond using hydrogen.
