Researchers from Glasgow Caledonian University in Scotland announce plans to tap abandoned mines for hot, underground water to potentially provide 40% of the city’s heating needs. Here’s more about the project from the University website:
Scientists at Glasgow Caledonian University have recently received funding from ScottishPower to map the maze of abandoned tunnels which exist beneath the city. The team will identify underground reservoirs of water which have the potential to heat homes and potentially to power under street heating.
One small city housing estate – Glenalmond Street in the East End – already uses geothermal energy and residents have heating bills of around £160 per year, as compared to £660 for an average Scottish family.
GCU’s Dr Nicholas Hytiris, a geotechnical specialist in the University’s Institute for Sustainable Engineering and Technology Research, said once the correct data have been gathered on the location of the underground water reservoirs, special ground source heat pumps could be used to extract heat from the water. The extracted energy would then be used for the heating of homes or offices.
He said: “After Hamburg and Stockholm, Glasgow could be the third city in the world to have under street heating. In three years’ time we will have a full and accurate record of what is going on beneath our feet and then we can go on from there.
