Ordnance Survey and the Coal Authority have collaborated on an exciting project to understand the demand for heating across Great Britain’s coalfields, with a view to promoting and investigating how water in disused coal mines could be considered as a secure, low-carbon heat source to support former mining communities.

The project explored the types of buildings and the demand for heating and cooling in coalfield areas with support provided from the Department for Energy Security and Net Zero, and the Geospatial Commission.

Recovering heat from mine water is a proven technology, and could provide a sustainable, secure and low carbon heat resource for homes, offices, industry and agriculture. OS, Great Britain’s national mapping service, provided the Coal Authority with geospatial support, and accurate location and addressing data from the National Geographic Database, to quantify just how many homes, businesses and buildings could potentially benefit.
