Hydrogen
energy for the 21st century
What is hydrogen?
An odorless, colorless gas
The lightest chemical element
of the Universe, present in
abundance
Higher energy density (in mass) than fossil fuels
A fuel used for rockets because of its high energy content
“I believe that water will one day be employed as a fuel, that thehydrogen andoxygen which constitute it, used singly or together, will provide an inexhaustible source of heat and light, of an intensity of which coal is not capable. “
Jules VERNE - 1875
Current and future use
At present, hydrogen is mainly used in refining and in the production of ammonia and nitrogen fertilizers.
Its uses are set to expand considerably over the coming decades.

Production still imperfect
At present, the hydrogen consumed worldwide is a “manufactured” product, derived from industrial processes that emit high levels of CO2 (gray and blue hydrogen) or are very costly (green hydrogen).
Hydrogen production therefore has a cost: both economic and environmental.
Grey hydrogen
15kgof CO2
for 1kg of H2
1.6€/kg
Blue hydrogen
4-7kgof CO2
for 1kg of H2
3€/kg
Green hydrogen
2kgof CO2
for 1kg of H2
8€/kg
The emergence of native hydrogen will change all that, as it is naturally generated underground. It therefore requires no costly and/or CO2-emitting industrial manufacturing process.
