This vector contour dataset represents the distribution of the theoretical potential calculated 'identified resources' (in GJ/m2 or PJ/km2) for the hot sedimentary aquifers in the Sherwood Sandstone Group (SSG) in the East Yorkshire-Lincolnshire, Cheshire, Wessex and Worcester basins, for resource temperatures greater than 40 °C. The theoretical potential for 'identified resources' represents the estimated proportion of the geothermal resource that is available for development. The maps are provided in raster format at a 100 m resolution.  For consistency with other legacy estimations, additional columns have been added to the original layers to include the converted value of 'identified resource' to 'recoverable heat' in MW/km2, for equivalence to the method used by D J.R. Jones, T. Randles, T. Kearsey, T.C. Pharaoh, A. Newell (2023). https://doi.org/10.1016/j.geothermics.2023.102649. This dataset is derived from Rollin, K. E., G. A. Kirby, and W. J. Rowley.

This vector contour dataset represents the distribution of the theoretical potential calculated 'identified resources' (in GJ/m2 or PJ/km2) for the hot sedimentary aquifers in Permian formations in the Cheshire Basin (Collyhurst Sandstone Formation) and Worcester Basin (Bridgnorth Sandstone Formation), for resource temperatures greater than 40 °C. The theoretical potential for 'identified resources' represents the estimated proportion of the geothermal resource that is available for development.

This vector contour dataset represents the distribution of the theoretical potential calculated 'identified resources' (in GJ/m2 or PJ/km2) for the Carboniferous Fell Sandstone Formation (Mid Border Group) in the Northumberland-Solway Basin. The theoretical potential for 'identified resources' represents the estimated proportion of the geothermal resource that is available for development. For consistency with other legacy estimations, additional columns have been added to the original layers to include the converted value of 'identified resource' to 'recoverable heat' in MW/km2, for equivalence to the method used by D J.R.

Modelled hot sedimentary aquifer geothermal potential of Upper Devonian strata in the Midland Valley of Scotland.

This raster dataset shows the modelled P50 distribution of the theoretical potential 'heat recoverable' (Hrec) across the northern and southern early Carboniferous limestone (ECL) in Great Britain (MW/km2), at a resolution of 2500 m x 2500 m. Hrec is calculated for resource temperatures greater than 50°C, which represents the minimum temperature required for direct use of heat from hot sedimentary aquifer resources. Hrec represents the proportion of accessible heat in an aquifer according to the USGS definition described in e.g. Muffler and Cataldi (1978). Its calculation is part of the research published by D J.R. Jones, T. Randles, T. Kearsey, T.C. Pharaoh, A. Newell (2023). https://doi.org/10.1016/j.geothermics.2023.102649. Areas of high uncertainty are delineated in the published paper and the theoretical potential of the recoverable heat is presented with very high uncertainty.
