Hydrogen is already used as a fuel. It is the energy component of all fossil fuels but this includes large
quantities of pollutants, carbon, sulphur etc.
When fossil fuels are burnt in air the reaction is not reversible unlike hydrogen produced from water using
renewable energy. Hydrogen is part of water along with oxygen and this Hydrogen can be released as fuel
using electricity from any renewable source. This gives a truly Zero emission energy supply i.e. no pollutants.

The physical properties of Hydrogen
Chemical symbol H, Atomic number 1, Atomic weight 1.00794 Density 0.089g/ltr. at 0c and 1 atmosphere.
Lightest and most abundant element in the universe,
it makes up approx. 90% of the universe by weight.
Colourless and odourless gas at 298K.
Discovered in 1776 by Henry Cavendish an English Chemist
and Physicist. Sir William Grove was the first person to
produce Hydrogen by electrolysis he also invented the fuel
cell in 1839. Hydrogen is neither more nor less intrinsically
dangerous than any other gaseous fuel and there has been
gas piped into houses for decades without any undue fears,
there is also an increase in the amount of L.P.G. (liquid
petroleum gas) and C.N.G. (compressed natural gas) vehicles on the road, paving the way for safe gas fuelled transport. Hydrogen has been and can be used safely if appropriate
codes, standards, and guidelines are followed. Industry has produced, stored, transported, and used large amounts of hydrogen safely and routinely byfollowing standard practices
that have been established in the past 50 years. These practices can be emulated in non industrial uses of hydrogen to attain the same level of safety.
