This raster dataset shows the modelled P50 distribution of the theoretical potential 'heat-in-place' (HIP) across the northern and southern early Carboniferous limestone in Great Britain (PJ / km2), at a resolution of 2500 m x 2500 m. The HIP is calculated for resource temperatures greater than 50 degrees Celsius, which represents the minimum temperature required for direct use of heat from hot sedimentary aquifer resources. The HIP characterises the heat resource available 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.

This vector contour dataset represents the distribution of the estimated, theoretical potential 'geothermal resources' (in GJ/m2 or PJ/km2) for the Carboniferous Fell Sandstone Formation (Mid Border Group) in the Northumberland-Solway Basin. This grid is the heat-in-place, and represents the amount of heat contained in the productive parts of the identified aquifers (i.e. those with sufficient porosity and permeability to be considered hot sedimentary aquifer resources).

This vector contour dataset represents the distribution of the estimated, theoretical potential 'geothermal resources' (in GJ/m2 or PJ/km2) for the Triassic sedimentary aquifers of the Sherwood Sandstone Group (SSG) in the East Yorkshire-Lincolnshire, Cheshire, Wessex and Worcester basins, for resource temperatures greater than 40 °C. This dataset is the heat-in-place, and represents the amount of heat contained in the productive parts of the identified aquifers (i.e. with sufficient porosity and permeability to be considered as a hot sedimentary aquifer resource). This dataset is derived from Rollin, K. E., G. A. Kirby, and W. J. Rowley. Atlas of geothermal resources in Europe: UK revision.

This vector contour dataset represents the modelled depth in metres to the base of the Permo-Triassic in the Worcester and Cheshire basins, considered for their hot sedimentary aquifer geothermal resource potential. Depth maps for the other Permo-Triassic basins (Eastern England and Wessex) are not considered as a viable geothermal resource because of the limited porosity and transmissivity of the reservoirs, and were not modelled. This dataset is derived from Rollin, K. E., G. A. Kirby, and W. J. Rowley: Atlas of geothermal resources in Europe: UK revision.

This raster dataset shows the modelled P50 distribution of the theoretical potential 'heat-in-place' (HIP) across the combined Upper Devonian Kinnesswood Formation and Stratheden Group in the Midland Valley of Scotland (PJ/km2), at a resolution of 500 m x 500 m x 50 m. The HIP is calculated for resource temperatures greater than 50 °C (> 1400 m depth), which represents minimum temperature required for direct use of heat from hot sedimentary aquifer resources. The HIP represents the heat resource available 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 Kearsey, T.I., Receveur, M. and Monaghan, A.A., 2024. Modelled hot sedimentary aquifer geothermal potential of Upper Devonian strata in the Midland Valley of Scotland. The model is presented with high uncertainty.

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.

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.
