Summary
Coal mines are finding a second life as companies invest in repurposing huge, disused coal sites into geothermal power projects. In the U.K., the government and energy companies have been discussing the idea for several years, and it seems to be gaining momentum with the launch of the first geothermal mine projects this year.
Energy companies have realised the potential of flooding abandoned coal mines to provide vast quantities of geothermal power, as water in coal mines can reach a temperature of up to 20 degrees Celsius. Mine water geothermal heat (MWGH) systems use the water from flooded coal mines, which is heated through a natural process, to supply clean heat to houses and businesses in the surrounding area. This works by using heat exchangers and pumps to recover the heat and distribute it to buildings via district heating networks.
