Question

Why is Hydrogen considered as a clean fuel?

Answer 1

1. Hydrogen reacts with oxygen to form water along with production of heat(energy).

${\mathrm{H}}_2+{\mathrm{O}}_2\to {\mathrm{H}}_2\mathrm{O}+\mathrm{Heat}$

2. This principal is used in fuel cells to generate electricity .

3. Hydrogen can carry and store energy , therefore it is regarded as a fuel.

4. When hydrogen is used to produce electricity in fuel cells water is the main water.

5.Water in the form of water vapour is released to environment which does not cause any kind of pollution.

6. Therefore hydrogen is called as clean fuel.
