Unlock the potential of Near Surface Geothermal Energy
GRETA (Near-surface Geothermal Resources in the Territory of the Alpine Space) Mid-Term Conference, Salzburg, november 2017
“The implementation of low carbon and renewable technologies is urgently needed” stated Kai Zosseder from the Technical University of Munich at the GRETA mid-term conference in Salzburg on 7th November, “but the potential to utilize Near-Surface Geothermal Energy (NSGE) has not been properly highlighted so far”. For instance, in Slovenia, Erik Potočar, from the Ministry of Infrastructure, indicated that increasing the share of geothermal energy by 70% for heating, cooling and domestic hot water could be a way to meet the renewable energy sources requirements. Unlocking this potential is the aim of the GRETA project that brings together 12 partners from the Alpine Space.

Tools as the “Heat pump information system for the federal State of Salzburg” were presented. Best practices as well, like the use of sewer well to produce direct or indirect cooling in Munich (for BMW datacenter for instance). A special application particularly useful in the Alpine Space is developed by Triple.s: in Oberstdorf, 23 railway switches are kept ice-free by a geothermal system.
The scientific work carried out on the geothermal potential led to relevant outcomes regarding the development of geothermal energy. It can lead to conclusions such as “the investment cost of a geothermal installation in Courmayeur, due to the ground parameters, would be 38% lower than in Aosta (Politecnico di Torino)”. With this kind of tools, the GRETA project can help the decision-makers to target the zones where the use of near surface geothermal energy should be prioritized.
For the year to come, the partners will carry on the work to:
- Increase the knowledge of the spatial distribution of Near-Surface Geothermal Energy (NSGE) potential in the Alpine region.
- Exchange knowledge and best practices for the utilization of NSGE on a transnational basis.
- Develop a knowledge base for the implementation of NSGE in planning tools.
The consortium of the project is composed of advanced research centers (POLITO, EURAC, University of Basel, Technical University of Munich), National geological surveys (of Austria - GBA, Solvenia - GeoZS, France - BRGM), territorial authorities and network (ARPA Valle d'Aosta, Regione Lombardia, Climate Alliance), and business orientated organizations that promote geothermal solutions (INDURA, Triple.s). They have been working together for a year and a half, using their synergies and are well placed to propose innovative tools with high scientific added value like potential mapping or socially inventive regarding the stakeholder engagement.
