The results of investigations hitherto performed indicate that in the Upper Silesian region exists the possibility of carbon dioxide storage in geological structures. However, taking into account the considerable urbanisation degree, for storage are suitable water-bearing horizons and hard coal seams located on the outskirts of the agglomeration, whereas because of safety reasons areas intensively industrialised are not suitable (towns, large industrial objects). The best conditions for CO2 injection were ascertained in the horizon of Dębowiec layers in the Skoczów-Zebrzydowice area. The determined storage site has a sufficient capacity for the needs of a local CO2 emitter. The storage possibility concerns also mine workings of selected abandoned hard coal mines. The results of initial investigations have pointed out that the creation in the workings of low-pressure reservoirs (with pressure up to 0.6 MPa) or high-pressure reservoirs in selected, isolated workings (for pressure exceeding 1 MPa) can be considered. However, their storage capacity will be lower than in the water-bearing layers. Potential storage possibilities are connected also with hard coal seams - particularly seams occurring at great depth, in areas considerably tectonically affected and flooded, beyond the range of operating mines. However, it should be taken into consideration that possible CO2 injection will cause that coal resources in the CO2 storage area never could be extracted using mining methods or be subject to gasification and that other type of economic activity could be conducted only at a considerable distance, beyond the range of their mutual influence.
