UK’s Deepest Closed-Loop Geothermal System Installed: Scunthorpe General Hospital Pioneers NHS Net Zero Heating with CeraPhi Energy’s 550m CeraPhiWell™
UK’s Deepest Geothermal Heating System Goes Live: Scunthorpe General Hospital Leads NHS Net-Zero Revolution with CeraPhi Energy’s 550m CeraPhiWell™ Project By: Robert Buluma December 2025 – In a landmark moment for British clean energy and healthcare decarbonisation, CeraPhi Energy has begun installing the UK’s deepest closed-loop geothermal heat systems at Scunthorpe General Hospital, part of the Northern Lincolnshire and Goole NHS Foundation Trust. The project, which started in October 2025 and is on track for completion by February 2026, repurposes an existing 550-metre borehole into a revolutionary CeraPhiWell™ system that will deliver continuous, low-carbon baseload heat to the entire hospital campus. Why This Project Matters for UK Geothermal Energy Geothermal energy has long been seen as the “missing piece” in the UK’s net-zero puzzle. While wind and solar dominate renewable headlines, they are intermittent. Hospitals, however, need 24/7 reliable heat – exactly what deep ...
