Hydrogen accounts for less than 2% of Europe’s present energy consumption and is primarily used to produce chemical products, such as plastics and fertilisers. 96% of this hydrogen production is through natural gas, resulting in significant amounts of CO2 emissions.
Renewable hydrogen can be obtained via electrolysis using renewable electricity to split water into hydrogen and oxygen. It will play a key role in decarbonising sectors where other alternatives might be unfeasible or more expensive. It can be used to replace fossil-based hydrogen for transport and industrial processes, and to start new industrial products, such as green fertilisers and steel.
