This project is developing an innovative filtration approach to enable the use of wastewater in hydrogen production by removing sulphur contaminants that can damage electrolysers and reduce hydrogen quality.

The work focuses on adapting high-performance copper-based materials to remove hydrogen sulphide from both water and hydrogen gas streams, improving purity and system performance.

By enabling the use of lower-quality water sources, the project could expand where hydrogen can be produced, reduce reliance on purified water and support more flexible, scalable hydrogen systems.

It also contributes to environmental improvements by supporting wastewater treatment and strengthening the South West and South Wales as a centre for hydrogen innovation and deployment.
