The €2/kg Dream: Europe Bets on PFAS-Free Hydrogen

A new EU project is eliminating PFAS chemicals and cutting iridium use by 75% to make green hydrogen cost-competitive by 2030

10 Apr 2026

Europe has set itself an ambitious target: 40 gigawatts of electrolyser capacity by 2030, enough to make green hydrogen competitive with the fossil-fuelled kind. The difficulty is that the dominant production technology depends on materials that European regulators are phasing out and geologists can barely find.

Proton exchange membrane electrolysis, the preferred method for turning surplus wind and solar power into hydrogen, has two structural weaknesses. Its membranes rely on PFAS compounds, a family of synthetic chemicals that the EU is moving to restrict on health and environmental grounds. Its catalysts require iridium, a platinum-group metal so rare that a meaningful scale-up of European electrolysis could strain global supply on its own.

A new consortium called SUPREME, led by the University of Southern Denmark and backed by the EU's Clean Energy Transition Partnership, is attempting to solve both problems within a single three-year programme. Launched in February 2026, it brings together seven institutions across five countries with a shared cost ambition: €2 per kilogram of green hydrogen, broadly the threshold at which the fuel becomes competitive with its dirtier alternatives.

The work divides along two tracks. At Graz University of Technology, researchers are testing commercially available PFAS-free membrane materials against current industrial standards to determine whether any can survive continuous operation. Separately, the University of Southern Denmark and British catalyst firm Ceimig are targeting a 75% reduction in iridium loading, combined with recycling processes designed to recover around 90% of what remains. Fraunhofer ISE in Germany is producing membrane electrode assemblies at pilot scale, while Norwegian firm Element One Energy is contributing a rotating electrolyser design that modelling suggests could improve voltage efficiency by up to 10%.

The programme's logic is straightforward: building cleaner chemistry into the next generation of PEM technology before PFAS restrictions bite and iridium markets tighten. Whether the timelines align is less certain. Three years of research leaves little margin before 2030, and the gap between laboratory materials and industrial-grade durability has humbled more than one clean-energy programme. Europe's hydrogen ambitions are not short of momentum; they may yet prove short of membranes.
