Legacy BGS geothermal models: theoretical potential 'heat-in-place' for the early Carboniferous limestone (hot sedimentary aquifer resources) in northern and southern England

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.
