Green hydrogen

OverviewDefinitionElectrolysisUsesMarketProjectsGovernment supportRegulations and standards

Green hydrogen (GH2 or GH2) is hydrogen produced by the electrolysis of water, using renewable electricity. Production of green hydrogen causes significantly lower greenhouse gas emissions than production of grey hydrogen, which is derived from fossil fuels without carbon capture. Green hydrogen''s principal purpose is to help limit global warming to 1.5 °C, reduce fossil fuel dependence by replacing grey hydrogen, and provide for an expanded set of end-uses in specif…
