Repsol produces renewable hydrogen from biomethane from urban solid waste

Green Car Congress

The biomethane used as raw material was obtained from urban solid waste. In this way, Repsol replaces conventional natural gas with biomethane of sustainable origin to produce renewable hydrogen in its industrial complexes and thus decarbonize its processes and products. GW in 2030. billion, compared to the €5.5

Air France KLM signs 210M gallon SAF offtake agreement with DG Fuels

Green Car Congress

The feed-stock reduction is achieved primarily by supplementing the process with oxygen and hydrogen produced by water electrolysis units that are powered by clean wind and solar generated electricity. DGF replaces the coal gasification used by others with biomass gasification and natural gas reforming. —Christopher J.
