Empa and French Researchers Innovate Cost-Effective Materials for Green Hydrogen Production
A collaboration between Empa and French institutions aims to reduce costs in green hydrogen production by developing corrosion-resistant materials for electrolysis. The project seeks to replace expensive titanium and platinum with steel and titanium oxide coatings, potentially accelerating the commercialization of sustainable hydrogen technologies.

Researchers from Empa and partners in France are innovating corrosion-resistant materials aimed at reducing costs in green hydrogen production through proton-exchange membrane water electrolysis (PEMWE). The project focuses on substituting costly titanium and platinum components with steel and titanium oxide coatings, with early tests indicating enhanced corrosion resistance.
This initiative, supported by the Swiss National Science Foundation and Agence Nationale de la Recherche, could significantly lower the cost barriers currently hindering broader commercial adoption of green hydrogen, which is crucial for the global energy transition. The project is set to continue through 2026, with the team seeking industrial partners for large-scale commercialization.
