Aberdeen could generate heat from earth.
A report supported by Aberdeen City Council stated it is willing to support plans to drill a geothermal well below the ground.
It revealed a 2km vertical well could heat the Aberdeen Exhibition and Conference Centre (AECC) and houses nearby.
The project could cost around £2.3 million and save 22,170 tonnes of carbon emissions over its lifetime.
If it goes ahead, it would use the skills of the region’s oil and gas industry to be delivered.
Iain Stewart, Professor of Geoscience Communication at Plymouth University said: “Scotland’s push for clean, renewable energy means that it is exploring innovative ways to supply heat and power to communities.
“The exploitation of geothermal energy is one exciting frontier in how our mixed energy future might look. This study proposes a highly innovative approach to utilising our underground geothermal resource by advocating the drilling of a deep geothermal single well for the provision of decarbonised heat supply to the Anaerobic Digestion Plant and also to local dwellings at the proposed Aberdeen Exhibition and Conference Centre.”
