Port of Marseille Fos: JUPITER 1000: Hydrogen Electrolysis

06 May 2021

Since 2019, JUPITER 1000 has produced hydrogen through water electrolysis. Situated on the Piicto platform in Marseille Fos’ industrial zone, JUPITER 1000 is the first “power to gas” unit connected to the gas transport network in France. Supported by GRTGaz, seven industrial partners and financed by local, national and European authorities, this innovative technology consists in converting surplus renewable electricity to gas (hydrogen and synthetic methane), before storing it in existing gas networks.
