Hot Dry Rocks - Scotland
Hot dry rocks are a potential source of geothermal energy. In Scotland they are likely to exist as buried high heat production granites. Alongside other data from the Scotland Heat Map, information on the likely location of these rocks is used to identify areas where deep 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 work was carried out by the British Geological Society (BGS) and AECOM. Existing sources of data were used, no new measurements were taken. BGS used a number of sources to create this dataset.

Data on hot dry rocks (HDR) comes from a 2013 Scottish Government commissioned study into the potential for deep geothermal energy. The study was carried out by the British Geological Society (BGS) and AECOM. In geothermal systems involving hot dry rocks, heat is extracted from 'dry' crystalline rocks by fracturing them, injecting cool water into the hot fractured rock, and extracting the resulting hot water. HDR resources yield hot (100-200°C) water (or steam), and the thermal energy stored therein is converted into electricity at the surface. This dataset shows onshore parts of Scotland most likely to overlie intrusions of high heat production granites. The occurrence at outcrop in Scotland of intrusions with heat production values at and above the high heat production (HHP) threshold raises the possibility that substantial heat reservoirs exist where HHP granite intrusions are buried beneath a thick cover of low thermal conductivity rocks. Granite has a relatively low density compared to many other rock types, so large granite intrusions that are concealed in the subsurface may generate negative gravity anomalies that can be identified in regional geophysical surveys. The hot magma within an intrusion can affect the magnetic character of the rocks enclosing it, so concealed intrusions may generate positive magnetic anomalies that can also be detected by regional geophysical surveys. The assessment of potential 'buried hot granite' settings in Scotland was based largely on an assessment of current BGS bedrock geology maps, the BGS 1:500 000 series gravity and magnetic anomaly maps, and gravity modelling.
