Wales pioneers using floodwater from a disused coal mine as a renewable heating source.

Flood water from a disused coal mine in Wales is being used as a renewable heating source for the first time, pumping water to heat a nearby warehouse. The Welsh government sees potential in this method for reaching net-zero emissions, and the Mining Remediation Authority plans to develop similar projects across Wales. This system uses about 25 liters of water per second from the former Lindsay pit to provide heating, which could potentially extend to thousands of homes.
