A project that could provide up to 40% of Glasgow’s heat using water from abandoned coal mines is under way.
Scientists from Glasgow Caledonian University will study the city’s old tunnels to find reservoirs which can be pumped to create geothermal energy.
The first stage will focus on the Clyde Gateway Regeneration area and take three years to produce a blueprint of the city.
Geotechnical specialist Dr Nicholas Hytiris said once pools are found, ground source heat pumps could be used to begin extracting heat from the water. This would then be used to heat homes.
He said: “We believe this technology will be able to provide cheaper and more sustainable heating, which could be an answer to fuel poverty issues prevalent in many areas of Glasgow, particularly those with a mining past and a legacy of poor-quality housing and high unemployment.
“After Hamburg and Stockholm, Glasgow could be the third city in the world to have under-street heating.”
