The increasing demand for sustainable energy use and growing measures to improve environmental quality along with rising awareness toward benefits of renewable technologies impact ground source heat pump market. Interreg project GeoPLASMA-CE was focused on estimation of the shallow geothermal energy potential. The research was applied on pilot areas that were focused on urban and/or transboundary regions. One of the investigated areas was the region between Austria and Slovakia including towns Bratislava – Hainburg – Kittsee located in both countries with total area covering 603 km2. Bratislava city is representing urban area with higher density of population and higher demand of heat and cold. The second part represents rural area on the side of the settlements on Austrian side. The geological and hydrogeological setup (up to investigated depth 400 m) is characterized by various types and regimes of groundwater flow. The complex attitude for shallow geothermal energy potential included joint approach, harmonization of the necessary information, data and following compilation of geological, hydraulic and geothermal models. The high potential for shallow geothermal energy provides the opportunity to overcome certain challenges in cities. However, if geothermal energy is used extensively in a city and thermal effects of heating outweigh the effects of cooling and lead to the development of “urban-heat-islands”. The integrative approach was implemented and included not only outcomes of the geoscientific modelling but as well the comparison of the different standards, methods of evaluation of the legislative approach in both countries. Common strategies were outlined to deliver the proper information for the stakeholder. The article gives a basic insight to the resource management maps elaborated for open loop systems with possible installations in Quaternary aquifer. Though this is just one set of the delivered outputs within the project.
