Introduction

Natural Hydrogen (golden hydrogen) is found naturally occurring on the Earth's crust & is a renewable energy source

Main Body

Potential as a Fuel:

1Reduce reliance on fossil fuels - Coal = 164 of India's installed energy

2Hydrogen is more energy dense than gasoline, petroleum or other fuels

3Can power hydrogen fuel cell vehicles - NTPL has introduced H2 fuel cell buses

4Relatively clean source of energy cost with emissions being just water vapour - H2 + O2 => H2O (combustion)

5Reducing import reliance on fossil fuels - 85% of India's crude oil is imported

6Replace current method of hydrogen formation using natural gas releasing large amounts of carbon dioxide (gasification) - Carbon Dioxide (gasification)

7Next growing energy demand globally - India's energy demand to double by 2010 CERF

Why it's still untapped:

1Economic viability => Extraction costs higher than that of fossil fuels

2Requirement of mining causing environmental degradation

3Often found along with deposits of Methane (green house gas)

4Costs of storage of hydrogen

5Safety concerns with high flammability of hydrogen gas

6Limited exploration of potential deposits

7Requires mining of large amount of land => displacement of locals
