Europe’s largest PEM hydrogen electrolyser began operations at Shell’s Energy and Chemicals Park Rheinland, producing green hydrogen. As part of the Refhyne European consortium and with European Commission funding through the Fuel Cells and Hydrogen Joint Undertaking, the fully operational plant is the first to use this technology at such a large scale in a refinery. Plans are under way to expand capacity of the electrolyser from 10 megawatts to 100 megawatts at the Rheinland site, near Cologne, where Shell also intends to produce sustainable aviation fuel using renewable power and biomass in the future. A plant for liquefied renewable natural gas (bio-LNG) is also in development. Shell has a target to become a net-zero-emissions energy business by 2050, in step with society. As part of its Powering Progress strategy, Shell plans to transform its refinery footprint to five core energy and chemicals parks. This means Shell will reduce the production of traditional fuels by 55% by 2030. The Rheinland electrolyser will use renewable electricity to produce up to 1,300 tonnes of green hydrogen a year. This will initially be used to produce fuels with lower carbon intensity. The green hydrogen will also be used to help decarbonise other industries. The European consortium backing the project consists of Shell, ITM Power, research organisation SINTEF, consultants Sphera and Element Energy. The electrolyser was manufactured by ITM power in Sheffield, UK, and includes parts made in Italy, Sweden, Spain and Germany.
