The REFHYNE project is at the forefront of the effort to supply Clean Refinery Hydrogen for Europe. The project is funded by the European Commission’s Fuel Cells and Hydrogen Joint Undertaking (now Clean Hydrogen Partnership) and will install and operate Europe’s largest PEM electrolyser the Shell Rhineland Energy and Chemicals Park in Wesseling, Germany.

The plant will be operated by Shell and manufactured by ITM Power. The electrolyser has a peak capacity of 10 MW (megawatts) and will be able to produce approximately 1,300 tonnes of hydrogen per year. This decarbonised hydrogen can be fully integrated into refinery processes including the desulphurisation of conventional fuels. The project will use the hydrogen produced for:

  1. Processing and upgrading products at the Wesseling refinery site.
  2. Testing the PEM technology at the largest scale achieved to date.
  3. Exploring applications in other sectors including: industry, power generation, heating for buildings, and transport.

The REFHYNE project began in January 2018 and will conclude in June 2024.


REFHYNE project successfully concludes with final event, developing and operating a 10MW PEM electrolyser.
