Under certain conditions, renewable hydrogen can be considered as Paris compatible non-fossil gas. Under certain conditions, renewable hydrogen can be considered as Paris compatible non-fossil gas. Sectors where reducing emissions is most difficult such as the steel and chemicals or aviation, long-distance shipping and heavy-duty road transport could partly rely on renewable hydrogen or derived energy carriers such as liquid synthetic fuels or synthetic methane sourced from renewable electricity.
Renewable hydrogen (also called green hydrogen) produced through electrolysis with renewable electricity delivers climate benefits when compared to other gases. Hydrogen production linked to nuclear power is not supported. Hydrogen originating from fossil gas through steam methane reforming (also called blue hydrogen or grey hydrogen depending on the use of CCS) is certainly not renewable or green, is not sustainable and can by its nature not be compatible with a net-zero greenhouse gas emissions economy.
