Hot sedimentary aquifers are bodies of permeable rock that can conduct significant quantities of groundwater. These ‘hot wet rocks’ are a potential source of geothermal energy. Alongside other data from the Scotland Heat Map, information on the likely location of these rocks is used to identify areas where geothermal energy could be used as a low carbon, renewable heat source.
This data comes from a 2013 Scottish Government commissioned study into the potential for deep geothermal energy. The study was carried out by the British Geological Survey (BGS) and AECOM. No new measurements were taken. Instead, BGS used a number of published studies to create this dataset.
