ARTESIA has become a leading reference in its contribution to the energy transition, using its expertise to support one of the solutions of the energy mix that is open geothermal energy, the one that add value to the groundwater.

This technology consists in collecting groundwater, using its calories and cooling capabilities for heating and air conditioning purposes, and then optimally returning it to the “source” aquifer or a nearby river. This technology makes full sense when aquifer potentials allow it and the required thermal power exceeds 100 kW.

ARTESIA uses its expertise and technology on behalf of prestigious clients who trust it, for ambitious and innovative projects of recovery of groundwater, springs, old galleries and minefields for geothermal energy use, storage, hydro-electricity and circular economies.

ARTESIA is also selected as an expert as part of a scientific research conducted by the Royal Institute of Natural Sciences of Belgium that aims to understand the hydrogeology of the Paleozoic base of the Brussels region and its surroundings, determine its aquifer and economic potential for the deployment of open geothermal energy solutions. In this context, ARTESIA becomes the expert to understand and prevent the interactions of nearby geothermal systems using its robust and reliable predictive technology (interactions between existing systems of the “Gare Maritime” building and neighbouring buildings of the Brussels and Flemish Administrations).

Based on its expert opinion on the appropriateness of considering such a technology, ARTESIA custom-plans the optimal techno-economic process to achieve a high-performance and sustainable geothermal system. ARTESIA’s technology also provides storage opportunities that increase performances.

ARTESIA implements the hydrogeological characterization phases necessary to understand groundwater behaviour at the local and regional levels. The 3D hydrogeological model integrating and reproducing all the field measurements is then exploited as a tool to assist in the decision and to establish the optimized design of the configuration of pumps and injections. The success of such geothermal energy systems depends on the ability to reliably understand and integrate complex underground behaviors (heterogeneity of underground flows and heat transport in the basement) in order to avoid ultimately the system’s performance decline or even its abandonment. It is in that sense that ARTESIA is a quality reference and effectively supports and advises its customers who want to value the energy of their underground.

It is thus possible to valorize groundwater with the following benefits:

• A decrease in the carbon footprint
• An attractive return on investment compared to carbon-emitting systems
• Improved public image
