Sažetak
Geothermal sources are exploited in two basic forms, i.e., the primary form of thermal energy and that converted into electrical energy by using an adequate thermodynamic cycle. There is a possibility of applying several processes for the conversion of thermal into mechanical or electrical energy which depend on the thermodynamic characteristics of the geothermal water. Geothermal sources in Croatia do not contain steam of relatively high temperature, like in Italy, although both countries are nearly in the same position with respect to geothermal belt Geothermal sources in Croatia are mostly so-called low-temperature geothermal sources with water temperatures lower than 100oC. A few of them have been exploited, although the percentage of utilization of their available power is still very small. The low-temperature potential is a major disadvantage when it comes to power generation, since state-of-the-art geothermal power plants require reheated steam or hot water to operate. There is a common belief that the optimum way of exploiting low-temperature geothermal sources is heat generation. Therfore, this analysis is especially aimed at potential users and showing the technical and economical possibilities of using low-temperature sources for conversion of thermal energy into mechanical work and electrical energy.
