SUPREME (full title: Industrialization of new generation SUstainable, low-cost, high PerfoRmance, novel water Electrolysis Material, production & system) is a three year research project led by the University of Southern Denmark (SDU) and funded under the EU Clean Energy Transition Partnership.

PEM (proton exchange membrane) electrolysis is a key technology for converting renewable electricity into hydrogen, but current systems depend on PFAS-containing membranes and scarce platinum-group metals, contributing to high costs and supply-chain risks. Within SUPREME, PEM electrolysis that can produce green hydrogen without the use of fluorinated polymers (PFAS) is developed. The challenges are addressed through integrated innovations in membranes, catalysts, manufacturing, and system design.

The consortium combines complementary expertise with TÜBİTAK developing a PFAS-free membrane, SDU and Ames Goldsmith working to reduce iridium use and increase recycling of critical raw materials, Fraunhofer producing the new electrolyser materials, and Eonee evaluating the component in a new electrolyser design. Within SUPREME, CEET assesses commercially available materials and supports benchmarking.
