| Abstract |
Geothermal investigations in Serbia began in 1974, after the first world oil crises. The territory of Serbia has favourable geothermal characteristics, and there are more than eighty hydrogeothermal systems present in Serbia. The most important are located at the southern edge of the Pannonian Basin. In Serbia, excluding Panonian basin, there are 159 natural springs of thermal water with temperature above 15 degrees Celsius, with total flow 4000 l/s. In Pannonian basin there are 81 hydrogeothermal drillholes with total average flow of about 700 l/s, and water temperature that ranges from 21 to 82 degrees Celsius, by the end of 2012 only 19 drillholes were in use. Geothermal energy in Serbia is being utilized from hydrogeothermal drillholes for balneological purposes, in agriculture and for space heating with heat exchangers and heat pumps. The economic blockade (1991-2000) of Serbia stopped large projects of heating. However, caused by the global trends on one side and forced by EU on another, recently interests and investments in geothermal energy utilization increased where the greatest steps were made by the recent Project "Promotion of Renewable Energy Sources and Energy Efficiency", EuropeAid/129768/C/SER/RS" realization. Since 2010, 3 new hydrogeothermal drillholes were drilled and one rehabilitated, with total heat capacity of 13.6 MW. These sources are utilized for heating, aqua parks, water bottling and wellness centres. In addition, Republic of Serbia has defined the development strategy of energetic sector in order to increase total share of use of all renewable energy sources by the end of 2020 to 27% of all energy means. |
