Preliminary Assessment of the Geothermal Potential of the United Kingdom
The most likely sources of water at temperatures and flow rates suitable for geothermal development are in Permo-Triassic sandstones in deep sedimentary basins. The distribution and properties of these rocks, together with the quality of the water they contain, have been studied and their potential for geothermal energy development examined. The results are sufficiently encouraging for test drilling at selected sites.
The potential for geothermal power from hot crystalline rock has also been assessed from existing geophysical, geological and geochemical data. Heat flow data are limited but several granite batholiths have been identified as preliminary targets, mainly on the basis of their large volume (derived from gravity data) and their above average radiogenic heat production.
