INSPIRE - Net potential of closed shallow geothermal systems favorable scenario 2022 - Tertiary sector in Wallonia (BE)

This INSPIRE data layer illustrates the net potential of shallow closed geothermal systems, for the tertiary sector and a 2022 scenario in Wallonia. This INSPIRE compliant data layer is derived from the business data Subsoil technical potential of shallow closed geothermal systems (https://geoportail.wallonie.be/catalogue/2f946d6e-9545-4dc9-a4f5-263c6e…). The net potential maps are obtained by crossing the maps of energy demand density covered by geothermal PACs (taking into account surface constraints) in MWh/ha with the underground technical potential map considering the potential ranges defined for open systems in MWh/ha. In each mesh of 100m * 100m, the net potential corresponds to: Net potential= Technical potential-subsoil-medium, if coverable demand higher than medium technical potential subsoil Net potential=Coverable request, if lower than medium subsurface technical potential With the exception of areas where the technical potential underground is unknown, the technical potential underground is always higher than the demand of the residential sector, which means that the installation of shallow closed geothermal systems is a technical option to be considered everywhere when choosing energy solutions for this sector. The net potential corresponds to the demand covered by PACs, it is simply considered unknown in areas where the collected data do not allow to determine the underground technical potential of closed systems. This data was produced during the public service contract for the determination of the potential of shallow geothermal energy (less than 500m) for the production of heating and cooling in Wallonia. 2022 contract initialised by SPW Energie. A consortium of Walloon institutions (Uliège, Geogreen, Geological Survey of Belgium and Deplasse et Associés) coordinated by VITO (Flemish Institution for Technological Research) carried out the project. The users targeted for these maps are mainly consultancy firms, underground experts, local authorities, regional policy makers, investors and the general public.
