Assessment of the shallow groundwater potential of the Kooecierzyna morainic island for cold and heat seasonal energy storage.
A b s t r a c t. Low-temperature aquifer thermal energy storage (LT-ATES) is widely used on an industrial scale in the Netherlands. In Poland, where the Polish Lowlands were recently typed as a promising area in this respect, this method has not yet been tested. Because of the complex structure of subsurface geological formations of most parts of these lowlands, assessment of the technical and economic feasibility of this type of energy storage requires extensive investigations. In this study, the ATES potential of an area of a geodetic precinct size was assessed using the basic documentation, especially the “Hydrogeological Map of Poland” with explanations. As a study area, the Kościerzyna morainic island was selected which is the main pole of development of southern Kashubia. The results of the assessment show that, in addition to economic advantages, this area has favourable hydrogeological conditions for LT-ATES due to its location between the Kashubian Lake District morainic complex and the Tuchola Forest outwash plain. In this area, subject to appropriate engineering research, the investment of LT-ATES systems with a few megawatt cooling capacity is entirely possible. This paper presents the most important conclusions of the study which was submited to the archives of the Polish Geothermal Association in Kraków at the beginning of June 2020 (Lemoine, 2020).
