Geo-Green contributes to the GEOWAL project to map Wallonia’s geothermal potential
Geo-Green took part in the GEOWAL project, an initiative aimed at assessing the technical and economic potential of shallow geothermal energy (less than 300 meters deep) for heating and cooling in Wallonia.
A consortium of experts serving Wallonia
The GEOWAL project is the result of a collaboration between several renowned institutions:
• Geological Survey of Belgium (GSB): Brings its expertise in geology and subsurface mapping.
• University of Liège (ULiège): Contributes academic and scientific research, especially for open-loop systems.
• VITO: The Flemish Institute for Technological Research, specialized in sustainable technologies.
• Deplasse & Associés: An engineering consultancy specialized in drilling and geothermal energy.
• Geo-Green: Provides its recognized expertise in geothermal systems, particularly closed-loop systems.
This consortium was formed in response to a request from the Walloon Region, via the Operational General Directorate for Spatial Planning, Housing, Heritage and Energy (DGO4), to carry out this strategic project.
Geo-Green’s unique contribution to the GEOWAL project
Geo-Green was invited to join the consortium due to its recognized expertise in geothermal energy in Wallonia:
• Wallonia’s most extensive TRT database
Geo-Green holds the largest database of Thermal Response Tests (TRT) in the region, offering crucial information for evaluating the thermal properties of the subsurface.
• In-depth geological expertise
As experienced geologists, we have detailed knowledge of the Walloon territory — essential for interpreting geothermal data and effectively contributing to the mapping of geothermal potential.
Goals and future outlook of the GEOWAL project
The GEOWAL project aims to:
• Map geothermal potential: Develop precise maps that estimate the amount of energy the Walloon subsurface can provide based on drilling depth and the type of geothermal system used.
• Inform and raise awareness: Provide public and private stakeholders with tools to better understand the opportunities geothermal energy offers in Wallonia.
• Promote sustainable development: Encourage the use of geothermal energy as a renewable resource, thereby contributing to the region’s energy transition.
Geo-Green is proud to have contributed to this important initiative and reaffirms its commitment to sustainable development and energy innovation in Wallonia.
