Scoping report on the material requirements for a UK hydrogen economy

This scoping study assesses the raw material demand associated with the scale-up of a UK hydrogen economy, with particular focus on proton exchange membrane (PEM) electrolyser technology and platinum-group metals (PGM), specifically platinum and iridium. It considers their applications and importance; mineral production and supply chains; competing demands, and UK import reliance and key dependencies. It identifies potential supply-demand challenges and explores opportunities throughout the supply chain to ensure PGM supply can sustainably support PEM electrolyser growth. The research is based on a combination of literature review, analysis of trade statistics and stakeholder consultation.
