“…For future research, the use of more detailed land cover categorisation is recommended in which various remote sensing applications, such as satellite and unmanned aircraft systems (UAS), can be involved besides other land development data sources. Further considerable issues are the environmental impact of the extracted water, gas, salt and heat and the treatment and utilisation possibilities of the treated water even in agriculture [36,62,63]. The presented results may be involved in the investigation focusing on how the potential and needs meet.…”

The role of geothermal energy is smaller in the global energy mix than what its potential would indicate, but it can be improved by incorporating geothermal energy potential assessments into spatial planning. For adequate decision support and sustainable utilisation, subregion-scale assessments should be applied due to the high variability in geothermal characteristics. Different GIS tools were used for the interpretation and integration of the different spatial data into one model showing areas with their geothermal characteristics on maps. Considering the present study site with a size of 83 km × 103 km located in NE Hungary, 39 2D reflection seismic sections and high-resolution geological data of 137 thermal wells were interpreted in OpendTect and then in ArcGIS to define spatial differences in geothermal potential. It was found that nine geothermal subregions (GSRs) can be distinguished in the present study site based on the applied GIS algorithms. Each GSR was characterised and land-use structure was studied based on Corine Land Cover 2018. The exploitation of water with at least 30 °C is possible in all GSRs, while the maximum achievable temperature and reservoir geometry vary; a subregion-scale delineation framework is required for regional planning.

“…There are also significant thermal water utilisation centres north of the Derecske Trough [7,36]. This less-studied marginal area has a more diverse development in the sandy Upper Pannonian formation, which has an impact on the exploitability due to reservoir geometry and is thus worth examining.…”
