In the EU project SUPREME, an international research team with the participation of TU Graz is developing an electrolyser to produce green hydrogen more sustainably and efficiently.
Green hydrogen is considered an indispensable component of the global energy transition, but its production still faces massive economic and environmental hurdles. For example, the promising PEM (proton exchange membrane) electrolysis process, which is particularly suitable for producing green hydrogen when the supply of electricity from wind power and photovoltaic systems fluctuates, is still very expensive compared to production using fossil fuels. Sustainability also needs to be scrutinised here.
This is because it relies on environmentally hazardous substances such as forever chemicals (PFAS), which the EU wants to ban soon. These disadvantages are to be eliminated in the EU project SUPREME. Over the next three years, an international team led by the University of Southern Denmark with the participation of Graz University of Technology (TU Graz) will be conducting research on a PFAS-free and highly efficient electrolysis technology that also requires far fewer critical raw materials such as iridium and is therefore much more cost-effective.
