On the 24 June, the European Federation of Geologists hosted the “GeoConnect³d – Framing geothermal resource management” online event. The GeoConnect³d project develops and tests a new methodological approach to prepare and disclose geological information for policy support and subsurface management. The improved approach uses two regional-level case studies – the Roer-to-Rhine region and the Pannonian Basin. These regional, cross-border case studies are chosen to be complementary and sufficiently different in geological setting and degree of implementation of subsurface exploitation and management, in order to maximize their pan-European relevance. A novel bottom-up approach introduces two concepts that increase the geological understanding of an area and are aimed at providing a coherent geological context for evaluating subsurface applications and resolving subsurface management issues.
On top of the project presentation, the main discussion was on Wallonia’s (a region in Belgium) geothermal energy potential. The project discovered tangible opportunities for geothermal development on the Mons-Chaudfontaine axis. This potential is believed to be due to the particular geological setting of the Dinantian limestones. From an operational perspective, this would translate to low to medium enthalpy plants with the added benefit of being close to local communities with high demand in heating.
Based on these promising results, further investigations will be conducted and will need to go further in the central and eastern parts of Wallonia to fully discover the promising horizons and characterize them (depth, thickness, temperature and permeability).
