US' P2H2, Repsol validate green hydrogen technology

Power to Hydrogen and Repsol have completed a pilot of P2H2’s hybrid AEM electrolysis technology for large-scale green hydrogen.
Testing ran for more than 1,250 hours and met or exceeded targets on efficiency, flexibility and durability.
P2H2 projects hydrogen costs of €3.86/kg (~$4.49/kg), about 16 per cent below incumbent electrolyser technologies.
