Question

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

Answer 1

Answer:

Hydrogen gas is cleaner than Compressed Natural Gas (CNG). This is because CNG contains hydrocarbons. ... Hence, hydrogen as rocket fuel is cleaner than the CNG.

CNG and compressed hydrogen are compared to illustrate why CNG, but not compressed hydrogen, is a viable alternative vehicle fuel. It is shown that natural gas has a greater energy content per mole than hydrogen and that more moles of natural gas than hydrogen may be stored in a given volume under identical conditions.

Answer 2

Answer:

Hydrogen gas is cleaner than CNG. This is because CNG contains hydrocarbons i.e alkanes, alkenes, and alkynes.

Carbon acts as a form of pollutant in CNG. On the other hand, hydrogen is waste-free and the fusion of hydrogen does not produce any waste. Hence, hydrogen as rocket fuel is cleaner than the CNG.
