Green H2 production commences in Germany

German energy provider RWE commissions a 14-megawatt pilot electrolyser at Lingen. The plant is to provide insights for developing large-scale green H2 production facilities.

The facility on the site of RWE’s Emsland gas-fired power plant has a capacity of 14 megawatts (MW). It can generate up to 270 kilogrammes of green hydrogen per hour using electricity from renewable sources. Featuring two different electrolysis technologies, the pilot plant is to provide valuable insights for developing future industrial-scale hydrogen facilities. The first large commercial electrolyser plant is already being built only metres away. As part of the GET H2 Nukleus project, a 100-MW electrolyser is to be commissioned there by 2025, with its capacity to be expanded to 300 MW by 2027.
The pilot electrolyser consists of two sub-systems – an alkaline electrolyser by Sunfire with a capacity of 10 MW and a 4-MW plant designed and built by Linde using a PEM electrolyser (PEM: proton exchange membrane) from ITM Power.
Initially, the hydrogen produced in the pilot plant is to be added to the fuel for the power plant’s unit D gas turbine as part of a comprehensive test programme at the site. From mid-2025, it will also be possible to fill hydrogen-powered vehicles with hydrogen from the pilot plant at the Emsland gas-fired power plant. The construction work for a hydrogen filling station and a trailer filling facility for hydrogen has already commenced.
