Geothermal Energy Use, Country Update for Slovak Republic

Abstract

Geothermal waters in Slovakia were proven by 172 geothermal wells with the depth of 9 m to 3,616 m. After 2013, two new wells were drilled, none of them being put into operation yet. The total amount of 2,487 l/s of geothermal water were documented by realized geothermal wells. A total of 61 locations throughout the country use geothermal water for heating. The individual applications for installed capacity and annual energy use include: 16.6 MWth and 1,321.6 GWhth/yr of individual space heating, 16.2 MWth and 740.1 GWhth/yr for district heating, 27.3 MWth and 1,784.5 GWhth/yr of geothermal heat in agriculture and industry, 87.7 MWth and 5,022.7 GWhth/yr for bathing and swimming, and 78.1 MWth and 2,374.2 GWhth/yr for geothermal heat pumps. The total for the country is then 225.9 MWth and 11,243.1 GWhth/yr. The total amount of geothermal water utilized in the last period was 441 l/s in average per year. This utilization makes only 18 % of approved amounts of geothermal water.
