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 raster dataset represents the depth in metres to the top of the early Carboniferous limestone (ECL) over the Northern and Southern Provinces in Great Britain. The raster grid is provided at a 2500 m resolution. The layer can be used to identify prospective geothermal heat resources, such as areas with deep burial depths beneath thick Permian-Mesozoic sequences, as in the Cheshire Basin, and the flanks of the East Irish Sea and Southern North Sea basins; or beneath thick later Carboniferous strata, as in the Stoke-on-Trent area.

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.
