A process to split methane into its components, hydrogen and carbon, is advertised as a way to make hydrogen from fossil gas without emissions. Yet, claims that methane pyrolysis is free of CO₂ emissions or more efficient than water electrolysis are highly misleading.

      Yeah, if it’s being made with surplus power from renewables it’s great, basically a gaseous battery, but otherwise it’s just fossil fuels with extra steps.

          If we continue investing in wind and solar, at a certain point it will be an almost daily issue to have more power than is needed. If some of the excess could be turned into hydrogen it could be huge for decarbonizing transportation.
