“…In the Carpathian zone, Mesozoic formations are present in high temperature zones (see Figures 1 and 3), but the water flow rates observed are significantly lower there. The situation is similar with Miocene formations: in the Carpathian Foredeep, these locally exhibit favorable reservoir parameters but low temperatures (up to 30 • C), while in the sub-Carpathian zone, temperatures rise but at the expense of decreasing flow rates [10] (see Figure 3). [10,11,13]-location in Figure 1).…”

“…In a more regional perspective, prospects related to the use of geothermal energy in this area have been presented in numerous publications. These concerned the assessment of thermal water resources and conditions for their presence in the Polish Lowlands [2][3][4][5], the Carpathian Foredeep [6], the Western Carpathians [7] and the Małopolska region [8,9]. Characteristics of thermal water aquifers in the northern part of the area analyzed (excluding the Silesian and Carpathian zones) have been the subject of numerous studies [10][11][12][13][14].…”

In view of the disastrous air pollution in the Silesian–Kraków region, reducing emissions from the combustion of conventional fuels is a particularly important issue. Geothermal energy is among the clean and renewable sources of heat that could be used to this end, for instance for recreation or space heating purposes. However, its use in the region is limited, mainly due to insufficient knowledge of the characteristics of the geothermal complexes present. Mesozoic complexes in the region have much smaller energy resources compared to the Polish Lowlands or Podhale, but Paleozoic ones, mainly the Lower Carboniferous and Devonian, offer realistic prospects for energy extraction. The aim of this study was to identify geothermal conditions within the Lower Carboniferous–Devonian complex, primarily in terms of using the waters present there for space heating purposes. The prospective zones identified and indicated during the research are only forecasts, and their actual utility can only be confirmed after new wells have been drilled to verify the actual conditions.

Abstract:An analytical method is described that expresses the specifi c power of a fl ash geothermal power plant with fl ash temperature regarded as a variable. The analysis was carried out for a condensation temperature for fl uid exiting a theoretical turbine and for a given geothermal reservoir temperature. The method is a linear approximation of the established method for optimizing separator pressure. This linear approximation makes it possible to obtain an analytical expression for the optimum fl ash temperature (fi xing the separation pressure) at which the maximal specifi c power is obtained. A discussion arose in Poland during extensive research related to the application of binary systems, HDR (Hot Dry Rock), and EGS (Enhanced Geothermal System) technologies for the production of electricity. This concerned the hypothetical possibility of using geothermal fl ash systems for this purpose. Therefore, the above procedure was applied to Polish geothermal conditions to assess the theoretical possibilities of operating such systems at the reservoir temperatures anticipated in Poland. In the lower Triassic formations in central Poland, there are geothermal resources with temperatures hovering above 130°C. However, low net power values were estimated following the application of the procedure; when combined with the large investment costs involved (the high-temperature resources lie at a depth more than 4000 m), this is not condusive for the effi cient application of such systems. On the other hand, the possible application of binary systems to electricity production in that area is realistic and justifi ed.
