Developing cheaper catalysts for water splitting
Climate change is growing into humanity’s biggest threat. Renewable energy and energy storage technologies top a list of solutions. One such solution is proton exchange membrane electrolysis, which generates hydrogen by splitting water in proton exchange membranes. However, its use of high-cost electrocatalysts comprising rare earth metals, including iridium, ruthenium and platinum, make it an unattractive option. The EU-funded RENEW project aims to change this by conducting research and documenting water oxidation catalysts to develop a cheaper catalyst utilising more abundant metals like cobalt, iron and nickel. The findings of this project could potentially transform energy sectors worldwide.
