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.
