Flooded coalmines can provide low-carbon energy, experts say
The Guardian
|November 07, 2025
Flooded disused coalmines could be a significant source of energy and provide cheap heat to thousands of homes, a new report argues.
Mine water geothermal heat (MWGH) systems use the water in flooded coalmines, which is warmed by natural processes, to supply low-carbon heat. Heat exchangers and pumps recover the heat, which is distributed via district heating networks to homes and buildings, providing low-cost, long-term, stable energy.
The report estimates that about a quarter of UK homes sit above flooded workings where MWGH could be used to provide low-cost heat, and that the technology could play a significant role in helping the UK meet its carbon reduction targets, cutting emissions by an estimated 10-20%.
MWGH systems produce minimal greenhouse gas emissions compared with conventional gas boilers.
