Hydrogen has been used as a rocket fuel. Would you consider it a cleaner fuel than CNG? Why or why not?

 

Answer

Even though CNG is termed as a clean fuel, when CNG is burnt, it produces some carbon dioxide which causes air pollution.

Incomplete combustion of CNG can lead to the production of carbon monoxide, which is a really harmful gas.

 

On the other hand, when hydrogen is burnt, it produces water vapour.

Water vapour does not contribute to any kind of pollution.

Hence, hydrogen is a better fuel than CNG.
