They are relics of Scotland’s industrial past and have lain disused underneath Scotland’s biggest city for decades. But abandoned coal mines in Glasgow’s East End are experiencing a new lease of life thanks to an innovative project which could transform them into renewable energy sources. Scientists believe untapped mine water underneath Dalmarnock and Rutherglen’s Cuningar Loop could generate geothermal energy to help heat homes and businesses. The UK Geoenergy Observatory in Glasgow has been studying the sites for a number of years and has now completed a first survey of the water circulating up to 88m below the city. The only facility of its kind in the world, the observatory has used boreholes to yield important data on the status of the mine systems and the role they could play in decarbonising energy supplies. Alan MacDonald, of UK Geoenergy Observatories, said: “The latest data show that the boreholes of the Glasgow Observatory are well-connected to the flooded mine workings. “We discovered that the mine water between 50 and 90m below Glasgow is 11-13C. This compares to Scottish groundwater, which has an average temperature of 10C. Understanding the temperature underground and how it varies will help us understand the heat energy resource.
