Wales & West Utilities (WWU) is embarking on an innovative project to develop an electrolyser capable of producing green hydrogen from highly contaminated industrial wastewater sources. This new technology, in collaboration with HydroStar and Cardiff University, aims to address the challenge of producing green hydrogen which typically requires highly purified water. By combining pollutant removal with the hydrogen production process, the project seeks to make green hydrogen more accessible and affordable for customers. The initiative, part of the NextGen electrolyser project, aims to optimize electrode designs for efficient green hydrogen production and is supported by Ofgem's Strategic Innovation Fund. The project also received funding from Innovate UK Launchpad: NetZero Industry in South West Wales. The collaboration between WWU, HydroStar, and Cardiff University will focus on developing electrode designs, optimizing processes, and enhancing pollutant capture and removal efficiency. The prototype is expected to be ready by March 2025. This project highlights the commitment to sustainability and innovation in the pursuit of green hydrogen production within Wales.
