Evaluation of possibilities of CO2 geosequestration in geological structures of the Czech Republic
(2009) Bujok, Petr; Němec, Jaroslav; Konečný, Pavel; Němec, Petr
The present-day emissions of carbon dioxide (CO2) generated by anthropogenic activities and the expected future growing production of them are even now a serious ecological problem. One of possibilities of solving this situation is CO2 storage, i.e. the building of CO2 storage sites in suitable parts of the rock mass. They are represented, in addition to ideal localities, which are mined-out deposits of natural gas and oil, by selected geological formations of sedimentary Carboniferous deposits of hazd coal, it means localities of closed underground hard coal mines provided that they are ''tight'' enough. For the purposes of CO2 geosequestration, theoretically all closed hard coalfields exploited using the underground method in the Czech Republic can be considered, namely the Rosice-Oslavany (RUD), Kladno, Zacler-Svatonovice and Most Coalfields, and partial localities (closed mines) in the Czech part of Upper Silesian Hard Coal Basin (Ostrava-Karvina Coalfield). Of hydrocarbon deposits situated especially in the Vienna Basin, the Poddvorov, Nitkovice, Kostelany-vychod and Zdanice-zapad structures seem to be most promising.
