Item type:Article, Access status: Open Access , Pilotowa instalacja odsalania wód geotermalnych w Polsce(Wydawnictwa AGH, 2011) Tomaszewska, Barbara; Hołojuch, GrażynaThe pilot geothermal water desalination installation in Poland was commissioned at the Geothermal Laboratory of the Mineral and Energy Economy Research Institute of the Polish Academy of Sciences (PAS MEERI). Laboratory is localised in Podhale region, in south-eastern Poland. Geothermal waters are extracted from carbonate formations of the Middle Eocene and from Middle Triassic limestones and dolomites. These exhibit relatively low mineralisation - 3 g/dm$^{3}$. Their temperature at the well outlet ranges 90°C. Installation is supplied with water at a temperature of about 35°C. The capacity has been set at 1 m$^{3}$/hour of desalinated water. The objective of geothermal water desalination will be to obtain water that meets the requirements stipulated in the regulation of the Minister of Health of 29 March 2007 (Journal of Laws of 2007, No. 61, item 417) concerning the quality of water intended for human consumption. The preliminary results from the geothermal water desalination study conducted at the PAS MEERI are optimistic. In order to validate the assumptions made in the context of industrial applications, further studies have to be conducted in accordance with the project plans. It is certain, however, that the utilization of geothermal water for drinking purposes on an industrial scale will require, first of all, better and more efficient water cooling. Optimum utilization of the thermal waters obtained is an important issue for most geothermal plant both in Poland and abroad. Efficient geothermal water management has one main goal: optimizing system operation and improving the economics of geothermal plant operation. Additionally, the use of cooled water for drinking purposes, particularly for open drain installations (without injecting cooled water into the formation) will contribute to the comprehensive utilization of geothermal water and the decentralization of drinking water production. Therefore the present study concerns two significant research areas: geothermics (cooled water utilization methods) and hydrogeology (water management).Item type:Article, Access status: Open Access , Possibility of energy storage in salt caverns(2016) Lankof, Leszek; Polański, Krzysztof; Ślizowski, Jarosław; Tomaszewska, BarbaraIn this article the methods of energy storage in salt caverns in the form of hydrogen, compressed air and natural gas were compared. Also the general issues concerning the geological, ecological and legal requirements for the storage of substances in rock salt deposits as well as the possibility of analyzed substances storage in the Zatoka Gdańska region and in the Goleniów salt dome were discussed. Moreover the suggestions concerning management of the brine coming from caverns leaching were also presented in this article.Item type:Article, Access status: Open Access , BPA - an endocrine disrupting compound in water used for drinking purposes, a snapshot from South Poland(Wydawnictwa AGH, 2020) Kmiecik, Ewa; Styszko, Katarzyna; Wątor, Katarzyna; Dwornik, Małgorzata; Tomaszewska, BarbaraBisphenol A (BPA) is a chemical produced in large quantities for use primarily in the production of polycarbonate plastics and epoxy resins. As an endocrine disrupting compound, it has been included in the list of substances requiring special supervision as a very high-risk substance due to its toxic influence on reproduction. BPA with a reference value of 0.01 μg/L was included in the Drinking Water Directive revision (DWD 2018). This paper presents the results of preliminary studies aimed at identifying the occurrence of BPA in different types of water, i.a. groundwater captured with house wells or flowing wells in a selected location in southern Poland. These waters are commonly used as a source of water intended for human consumption and their quality is not regularly controlled. Additional tests were carried out for surface water, as well as water from springs used for drinking purposes. The authors also analysed tap water from various sources, i.e. surface and groundwater, as the final product of the drinking water production cycle. The results indicate the presence of BPA in water and the necessity of a detailed study on the risk of the BPA occurring in groundwater, especially in domestic wells.Item type:Article, Access status: Open Access , Geological and environmental implications of the utilisation of geothermal energy in the Lahendong working area, Indonesia(Wydawnictwa AGH, 2022) Mukti, Mentari; Tomaszewska, Barbara; Starczewska, Magdalena; Ningrum, Eva OktaviaThis study presents the characteristics of the Lahendong geothermal working area (GWA) in terms of the geological, geophysical, geochemical, and environmental implications. The investigated area is located in the Sulawesi North Arm, where the volcanic arc extends from Sangihe Island to Minahasa with two major strike-slip faults. NE–SW (northeast-southwest) trending faults control the thermal surface manifestation. The geothermal field is grouped into two hydrochemical systems: acid-sulphate-chloride (acid reservoir) and chloride (closer to neutral) types. The environmental implication analysis shows that the North Sulawesi province is experiencing water shortages due to excessive mining activities, inadequate wastewater management, and periods of drought. Although geothermal wastewater is being re-injected, the possibility of water contamination by hazardous materials from geothermal power plant activity is still evident. This study reviews the actual geothermal utilisation in the form of the 120 MWe power plant, the 500 kWe binary power plant, while the heat from geothermal energy is used for palm sugar production. Furthermore, the article also analyses the potential of the rational use of geothermal resources in this area. As a result of the high salinity and silica concentration of the brine, the geothermal wastewater should be treated before further utilisation and it potentially benefits both local communities and geothermal companies.Item type:Article, Access status: Open Access , Geothermal water and energy management in Polish district heating – directions for effective use in the Polish Lowlands(Wydawnictwa AGH, 2025) Pierzchała, Karol; Pająk, Leszek; Tomaszewska, Barbara; Tyszer, Magdalena; Kępińska, Beata; Kasztelewicz, Aleksandra; Stokłosa, Alicja Wiktoria; Pétursson, BaldurThe possibility of utilising the available potential of the main geothermal reservoirs in Poland, i.e., the Lower Jurassic and Lower Cretaceous, by using the existing infrastructure in the form of still-operating district heating networks is the subject of this work. The suggested solution, therefore, integrates the resource side with the infrastructure side. This approach should significantly accelerate the implementation of the proposed solutions, supporting the achievement of the ambitious objectives of Poland’s Energy Policy 2040. Geothermal resources in Poland are characterised by low enthalpy and low temperature. Their temperature is often too low for direct utilisation in systems relying solely on geothermal energy. Existing district heating networks require significantly higher heating medium temperatures during specific periods (when low ambient air temperature is observed). Using gas boilers as peak energy sources while employing geothermal energy as the base load for meeting annual heating demands appears to be an attractive and feasible technical option. Poland, alongside Denmark, Latvia, Finland, Estonia, and Lithuania, is among the countries with the highest density of district heating networks. These networks serve as invaluable infrastructure, reducing the costs associated with geothermal energy extraction. However, this infrastructure is under real threat from the trend towards decentralised energy systems. The liquidation of district heating networks would be irreversible, further exacerbated by the lack of access to clean and alternative energy carriers to replace fossil fuels. It has been demonstrated that in most analysed cases the combination of available geothermal resources and district heating infrastructure can successfully contribute to achieving the assumed goals of Poland's Energy Policy. In the best locations, the share of renewable energy exceeded 80%, with an average of around 50%. The total reduction of $CO_2$ emissions is estimated as 1.16 million tonnes yearly. The work draws attention to the slow but positive change in the electricity mix, in which the share of RES is growing. This trend is extremely beneficial for popularising heat pumps powered by electricity using geothermal resources as a low-temperature energy carrier.Item type:Doctoral Dissertation, Access status: Metadata only , Antropogeniczne przeobrażenia w środowisku wodnogruntowym na przykładzie Skawiny(Data obrony: 2001) Tomaszewska, Barbara
