Question

hydrogen is considered as a future fuel mention advantage of hydrogen as a fuel ? ( 5 advantages max )

Answer 1

Advantages of hydrogen are:
1) It is not a pollutant. Does not harm the environment.
2) It has a high calorific value.
3) It does not produces residues like ashes after burning.
4) When hydrogen burns, pollutants like carbon dioxide are NOT produced.
5) Hydrogen is used in fusion - reactions of nuclear energy. The enormous heat so produced breaks the fused He nucleus into hydrogen atoms which again joins to form a He atom, releasing a lot of energy. In this way, the hydrogen atoms (or molecules) can create a long self-sustaining energy chains that would keep releasing large amounts of energy.
