Why use Hydrogen as an energy fuel in the first place?

Hydrogen is a very good energy vector; with an energy density of 33 kWh per kilogramme, hydrogen contains three times more energy than diesel and 2.5 times more energy than natural gas.

The future fuel cells is on hydrogen-production technologies that result in near-zero, net greenhouse gas emissions and use renewable energy sources, or nuclear energy.

• ·          Hydrogen, chemical symbol "H", is the simplest element on earth. An atom of hydrogen has only one proton and one electron. 

• ·     Hydrogen gas has two atoms of hydrogen, which is why pure hydrogen is commonly expressed as "H2")

• ·     Although very abundant on earth, hydrogen rarely exists by itself as it normally combines readily with other elements and is almost always found as part of another substance, such as water, hydrocarbons, or alcohols.

• ·     Hydrogen is an energy carrier, not an energy source. Hydrogen can store and deliver usable energy, but since it rarely exists in nature, it must be produced from compounds that contain it.

• ·     Hydrogen can be produced via various renewable process technologies, including thermal (natural gas reforming, renewable liquid and bio-oil processing, and biomass and coal gasification), electrolytic (water splitting using a variety of energy resources), and photolytic (splitting water using sunlight via biological and electrochemical materials).

• ·     In order for hydrogen to be successful in the market place however, it must be cost-competitive with the available alternatives.
