| Abstract | Hungary is well-known as a country of favorable conditions in terms of geothermal resources having a geothermal gradient higher than the world average. As a consequence of the abnormally thin lithosphere the heat flux of 80-100 mW/m2 is above the average for the continent and the mean geothermal gradient of 20m/oC is steeper than the normal 30-33 m/oC. The highest surface temperature of low enthalpy thermal waters is 97oC and geothermal brine from geopressured reservoirs 1710C the highest aquifer temperature registered 140oC and 220oC respectively. The utilization of geothermal energy in Hungary has to be in harmony with geothermal and hydrological possibilities of supplies of thermal water, protection of hydrological reserves and the requirements of environmental protection. The utilization of geothermal energy in Hungary would be profitable in case of multistage utilization, in energy cascading system, with electric power generation for direct use. Also increase of the efficiency of heat conversion from abandoned CH-weeks and establishment of new forms of undertaking. |
