Research project looks to eliminate PFAS and iridium from PEM electrolysis

This article was originally posted on Chemical Engineering Online.

Summary
A new research project aims to remove PFAS “forever chemicals” and scarce iridium catalysts from PEM electrolyzers to reduce environmental risks and costs. By developing PFAS-free membranes and iridium-free catalyst systems that can operate efficiently with fluctuating wind and solar power, the effort seeks to make green hydrogen more competitive with fossil-based production.

What do you think is the toughest barrier to replacing PFAS and iridium in PEM electrolysis—matching performance, ensuring durability, or scaling manufacturing?

The 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 is also a concern, because it relies on environmentally hazardous substances such as forever chemicals (PFAS), which […]
