ThermoMap (2010 – 2013)


Area mapping of superficial geothermic resources by soil and groundwater data

The ThermoMap project focusses on mapping the potential of very shallow geothermal energy in Europe. Very shallow geothermal energy within the first 10m below the earth surface is predominantly influenced by solar energy input and thus belongs to the renewable energy resources. Variations of air and soil temperature and heat flow in low depths are controlled by external variables like effective sun radiation, distribution of rainfall and infiltration processes based on site specific soil conditions. This energy resource can be best exploited in the saturated and unsaturated zone of the unconsolidated rock zone where easy access to the underground is possible.

The ThermoMap project will harmonise and analyse already existing data collections (geological, hydrogeological, soil, climate, land use/land cover and relief geodata) with standardised methods to calculate a value for the geothermal potential on three different low depth levels in order to help finding favorable areas for superficial geothermal exploitation in a very short time and without high costs. The resulting geothermal potential values will be integrated in an Open Source WebGIS as well as all necessary geodata. The 12 participating project partners of 9 EU member states will define an exemplary test area in each country. For these 9 test areas the geodata and calculated geothermal potential values will be shown on cadastral parcel level, while for the entire EU area there will be created a shallow geothermal potential overview map in scale 1:250 000.
