Green hydrogen:
the tipping point to zero-carbon energy now

Renewable hydrogen

Upstream

Matching the cost
of fossil fuels

Green hydrogen can be produced from solar and wind for as low as 1 $/kg (25 $/MWh).

Renewable hydrogen

Midstream

Reusing existing oil and gas infrastructure

Gas transmission and storage as well as coal and gas turbines can be refurbished with limited investment.

Renewable hydrogen

Downstream

Meeting 24/7 energy needs
in industry, power, heat
and transportation

Chemicals, steel-making, power generation, trucking, shipping can smoothly shift their processes to hydrogen.

“Water is the fuel of the future”

Jules Verne in l’Ile Mystérieuse (1874)
  • “But then what will be discovered?” asked Pencroft. “Do you have a sense of it, Mr Cyrus?”
  •  “Just about, my friend.”
  •  “And what shall be burned instead of coal?”
  •  “Water”, replied Cyrus Smith.
  •  “Water!” shouted Pencroft, “water as fuel for steamers and engines! Water to heat water!”
  •  “Yes, but water decomposed into its primitive elements”, replied Cyrus Smith, “and decomposed doubtless, by electricity, which will then have become a powerful and manageable force, for all great discoveries, by some inexplicable laws, appear to converge and combine at the same time. Yes, my friends, I believe that water will one day be employed as fuel, that hydrogen and oxygen which constitute it, used singly or together, will furnish an inexhaustible source of heat and light, of an intensity of which coal is not capable. Some day the coal bunkers of steamers and the tenders of locomotives will, instead of coal, be stored with these two condensed gases, which will burn in furnaces with enormous calorific power. There is, therefore, nothing to fear. As long as the earth is inhabited, it will provide for the needs of its inhabitants, and there shall be no shortage of either light or heat, just as surely as the productions of the vegetable, mineral or animal kingdoms will not fail us. I believe, then, that when the deposits of coal are exhausted, we shall heat and warm ourselves with water. Water is the coal of the future.”
  •  “I should like to see that”, observed the sailor.

What is electrolysis?

Hydrogen is only available in infinitesimal quantities in pure form in nature. It can be produced from fossil fuels (steam methane reforming) in a process which emits large quantities of CO2. Hydrogen can also be produced by electrolysis from water, a process invented by two British chemists in 1800, in a reaction that also produces oxygen: 2 H2O + electricity = 2 H2 + O2 + heat. The electrical activation between a cathode and an anode creates a chemical reaction. The energy content of water is considerable: 1 liter of water contains the equivalent of 0.4 liter of oil.
