How is green hydrogen produced?
To put it simply, it is produced by applying an electrical charge to water, which breaks the link between the atoms forming the H2O molecule, thereby yielding two distinct gases: hydrogen and oxygen. This procedure is called electrolysis. The resulting hydrogen is then captured for future use of the potential energy it contains, whereas the oxygen can be captured and transported, or simply released into the atmosphere.
To obtain green hydrogen, we have to use electricity generated through 100% renewable sources such as hydroelectric dams, wind farms, solar farms, biomass and geothermal energy.
When it is used, hydrogen reacts with the ambient oxygen and releases a tremendous amount of energy in the form of heat or electricity, giving off nothing but water vapour as its combustion gas.
