Clean hydrogen plays a key role in the decarbonization of both industrial sectors, like steelmaking and petrochemical processes, and transportation sectors, like aviation fuels and heavy-duty trucking. It may also serve as a key long-duration storage technology to meet rising electricity demand. It can be produced using different technologies, including but not limited to: electrolysis powered by clean electricity, natural gas reforming with carbon capture processes, methane pyrolysis, co-production with chlor-alkali, and even mining, as clean hydrogen can be formed geologically underground.
