Underground thermal water sources could be used to heat homes and businesses around Scotland if a new feasibility study in Fife is a success. A green energy centre run by the University of St Andrews is to investigate the possibility of heating buildings using warm water recovered from sedimentary rocks deep below the ground. The University is lead partner in a Scottish Government funded project based at the Guardbridge Energy Centre, which it operates. Experts hope geothermal energy could provide significant amounts of renewable heat for Scotland, helping to reduce greenhouse gas emissions with a low carbon heat source. The project will establish whether it such geothermal heat sources offer a financially viable resource. Dr Ruth Robinson, the lead for the project at the University of St Andrews, said: “Extracting geothermal heat from sedimentary rocks is similar to getting drinking water out of the ground, except in this case the water is warm enough to be used for heating. University of St Andrews Executive Director for Guardbridge, Ian McGrath said the project was just one of the renewable energies being explored at the industrial site, which has previously housed a distillery and paper mill. “We believe the diverse range of potential uses for Guardbridge has the capacity to re-establish this huge site as a key economic centre in Fife,” he said. St Andrews University is investing £25 million at the site, five miles west of St Andrews, to generate power through clean biomass and pump hot water 4 miles underground to St Andrews to heat and cool its labs and residences. Alongside plans for a six-turbine wind power development at Kenly to the east of the town, the Guardbridge scheme aims to help St Andrews to become the United Kingdom’s first carbon-neutral university.
