“…In Poland, the absolute value of water temperature is determined with the surface changes in intensity of the normal heat flow of the Earth. The value of the heat flow ranges from 25-40 mW/m 2 in the Precambrian platform up to 50-90 mW/m 2 within the Palaeozoic platform and 50-80 mW/m 2 in the Alps orogen of the Carpathians (Bujakowski et al 2016). For Podhale, the density of the heat flow is estimated at 60-70 mW/m 2 and differs slightly from the average world density of geothermal energy stream of 60 mW/m 2 (Sobański et al 2000).…”

At present, hydro-geothermal resources in which waters in bores are the carrier of heat energy have commercial importance in Poland. Geothermal waters should feature the highest possible temperature in the outflow, low mineral content, high capacity and low deposit depth. Even though geothermal energy is included in renewable sources of energy, complete depletion of the deposit is the largest risk in extracting geothermal waters. This is why these waters should also feature deposit renewability. There are currently several geothermal provinces with beneficial geothermal conditions in Poland, with the area of the Podhale Basin in the Inner Carpathians region being regarded as the most promising. The Podhale deposit also meets all of the above listed conditions. The possibility of using hydrothermal energy in Poland is practically available throughout the country, but operational use of hot groundwater must be profitable for investors. From another point of view, the environmental impact of such investments should be minimized. This paper is concerned with the special variety of temperature of geothermal waters extracted in the area of the Podhale Basin, which is the basic aspect in using deposits of this type.

“…Geological conditions of geothermal resources in Poland have been analyzed since the 80s of last century and geothermal waters have already found applications in heating, balneotherapy and recreation [8][9][10][11]. Those geothermal resources are related to underground waters of different stratigraphic layers (thereby various depths) within four major provinces that are subsequently: the Polish Lowlands, the Carpathians, the Carpathian Foredeep and the Sudetes (Fig.…”

Geothermal energy is an internal heat of the Earth, that is a prospective and sustainable source of renewable energy. In Poland, despite having significant amount of low-temperature geothermal resources, its share in the national energy mix remains marginal but growing. Currently, the utilisation of geothermal resources is related to hydrogeothermal resources, that are used mainly in space heating, recreation and balneotherapy. Nevertheless, the indication of potential electricity production is under research. The utilisation of geothermal resources entails a plenty of environmental benefits that are particularly important in the context of the present pollution problem. Therefore, the development of the geothermal energy sector is of relevant importance and with appropriate legal and financial conditions it may have a bearing on improvement of the environment’s quality and, ipso facto, living in Poland. Thus, this paper presents numerous possibilities of obtaining a financial support for investments in geothermal energy sector. Selected funding and financial backing systems currently available in Poland are discussed. The importance of opportunity of obtaining a financial support for an investment as one of the crucial factors for the geothermal sector development is emphasised. Moreover, the examples of installations implemented in the country in the context of obtained funding are presented.

“…Investigated geothermal water is classified as sulfate-chloride-sodium-calcium water (according to Szczukariew-Prikłoński classification). Mineralization of these waters is about 2.5 g/L, including specific component such as a metasilicic acid [5][6][7][8] and a temperature is between 82.9-86.3°C [9].…”

Abstract. The aim of this study is to assess the impact of samplers change on the uncertainty associated with the process of the geothermal water sampling. The study was carried out on geothermal water exploited in Podhale region, southern Poland (Małopolska province). To estimate the uncertainty associated with sampling the results of determinations of metasilicic acid (H 2 SiO 3 ) in normal and duplicate samples collected in two series were used (in each series the samples were collected by qualified sampler). Chemical analyses were performed using ICP-OES method in the certified Hydrogeochemical Laboratory of the Hydrogeology and Engineering Geology Department at the AGH University of Science and Technology in Krakow (Certificate of Polish Centre for Accreditation No. AB 1050). To evaluate the uncertainty arising from sampling the empirical approach was implemented, based on double analysis of normal and duplicate samples taken from the same well in the series of testing. The analyses of the results were done using ROBAN software based on technique of robust statistics analysis of variance (rANOVA). Conducted research proved that in the case of qualified and experienced samplers uncertainty connected with the sampling can be reduced what results in small measurement uncertainty.
