Hot Granite In The NE Has Geothermal Potential

Scotland’s first geothermal power station could be built near Aberdeen

Aberdeen’s fabled  granite bedrock could become the North-East’s newest energy source. Scientists believe that suitably high temperatures exist several miles underground in the so-called ‘Energetica’ development corridoor between Aberdeen and Peterhead, and also in other locations near Inverurie and Stonehaven.

According to geologists this may be accounted for by radioactive minerals within granite giving  off heat as they decay. This means that temperatures as high as 210deg C could be found at these depths – and of course the North-East has the drilling technology available locally  to reach this hot rock.
A major study is now being set up, funded by Scottish Enterprise, to look into the possibility of building a test plant somewhere  between Aberdeen and Peterhead. The geothermal power plant would be part of the Energetica project, which is  designed to help consolidate  Aberdeen City and Aberdeenshire’s position  as a global energy hub by creating a 30-mile corridor between Aberdeen and Peterhead which will be home to  energy technology companies, housing and leisure facilities.   
Energetica project director Sara Budge said:

“As part of our quest to make Energetica a world-class, all-energy destination, we are exploring various avenues for generating renewable energy in the corridor which stretches north from the Bridge of Don up to Peterhead and west to Aberdeen Airport.
“Geothermal is one source we are considering. We have just issued a tender to appoint an appropriate organisation to undertake a feasibility study into the potential for geothermal heat generation within Energetica but also in other locations across Aberdeenshire.”
