Question

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

Answer 1

Hydrogengas is cleaner than CNG. CNG contains hydrocarbons. Therefore, it has carbon contents. Carbon is a form of pollutant present in CNG. On the other hand, hydrogen is waste-free. The fusion of hydrogen does not produce any waste. Hence, hydrogen is cleaner than CNG. OR No doubt hydrogen gas is cleaner fuel than CNG as CNG contains hydrocarbons. Which contain carbon and it is a form of pollutant present in CNG. But hydrogen is waste-free. The fusion of hydrogen does not produce any waste. Therefore hydrogen is cleaner than CNG.
