Summary
Almost a quarter of the UK’s population lives above abandoned coal mines that could be used to warm homes and public buildings with low carbon heating.
That’s according to the British Geological Survey (BGS) and the Coal Authority, which suggest mines are warmed by natural geothermal processes and at places where they are flooded, the water can be used as a heat source for district heating systems.
The organisations, which created maps to show the extent to which heat is stored in Britain’s abandoned coal fleet, note that geothermal energy from mines, combined with heat pump technology, could provide a sustainable energy source.
The government has a target to increase the number of homes on heat networks from 2% to 18% by 2050.
Gareth Farr, BGS Geoscientist and Project Leader, said: “It’s the first time we have been able to visualise the temperature of Britain’s coalfields. We have found records of heat temperatures going back over 100 years and compared them to temperatures in the mines now, and found them to be quite similar.
