The paper presents an analysis of the possible location of geological formations suitable for CO₂ storage in the Upper Silesia Coal Basin, Poland. The range of the reservoir has been determined on the basis of an analysis of basic geological parameters, which determine the selection criteria for sites suitable for CO₂ storage. A dynamic modelling of the CO₂ distribution in the aquifer is presented. Based on the constructed model of migration, reactivity, and geochemical transport of CO₂ in geological structures, it is possible to identify potential migration routes and escape sites of CO₂ on the surface. The analysis of the technical and geological possibilities of CO₂ storage was carried out according to the regulations of the complex Polish geological law, specifically in terms of sequestration possibilities in geological formations.
