Grey hydrogen is the splitting of hydrogen from the carbon in natural gas which then reacts with oxygen to form CO2 which is released to atmosphere amplifying the greenhouse effect and warming our planet.
Green hydrogen uses renewable electricity to split water into oxygen and the most abundant element in the universe: hydrogen.
Today we live in a fossil fuel world, powered by hydrocarbon. Clean energy is what makes all the difference.
Blue hydrogen follows the same production process but captures and stores the CO2 for very long term storage.
Green hydrogen uses renewable power and water as its sources with no CO2 emissions, just hydrogen and oxygen.
The Mysterious Island –
In 1874, in his famous novel The Mysterious Island, Jules Verne wrote: “I believe that water will one day be employed as a fuel, that hydrogen and oxygen, which constitute it, used alone or simultaneously, will provide an inexhaustible source of heat and light of an intensity beyond what coal can offer.”
Hydrogen was identified by Henry Cavendish in 1796 when he discovered it as ‘inflammable air’.
As his naming suggests, it is a combustible element, and also the key energy component in any hydrocarbon, such as petrol.
Like petrol or natural gas, hydrogen is handled and moved safely every day in industrial processes.
The hydrogen revolution continues to build on these existing safety systems to enable the delivery of clean, safe new energy to both short and long distances.
Transportation of hydrogen.
Hydrogen for transportation.
Moving hydrogen around can be complex as being the lightest element it is small and needs to be moved at high pressure. Combining it with other elements – such as nitrogen (79% of the air that we breathe) to form ammonia – can create an effective medium for transportation.
Ammonia is immensely versatile and over 200 million tonnes of it are moved around the world every year. Ammonia also has potential as a fuel for transportation, in particular for shipping.
