​United Utilities secures £9.5m to scale biogas‑to‑graphene technology 

United Utilities has secured £9.5 million in funding from Ofwat’s sixth Water Breakthrough Challenge to scale up its biogas‑to‑graphene technology and demonstrate how wastewater can become a major source of advanced materials and clean hydrogen. The company will build on a world‑first trial to produce clean hydrogen and graphene from sewage‑derived biogas, aiming to move from pilot to full‑scale deployment and open new commercial routes for graphene in construction and energy storage.

Having already proven the concept with technology partner Levidian, United Utilities will now install a larger unit designed to produce roughly three times more sustainable hydrogen and graphene than the earlier demonstration system. The project is one of 19 winners in Ofwat’s latest Water Breakthrough Challenge round, with United Utilities leading two projects and partnering on nine more, all focused on turning wastewater streams into valuable resources.
