Preliminary results of the Slovakian national project regarding carbon dioxide storage in underground spaces

AbstractThe Slovak republic territory in spite of its extremely complicated geological pattern affords some possibilities for potential storage of carbon dioxide. The aim of the Slovakian National project “Quantitative parameters selected geological structures suitable for CO2 storage” is to find convenient places for this purpose in regional aquifers, and depleted hydrocarbon deposits. Besides, of these geological rock complexes–mostly ultramafic rocks - have been investigated for purposes of mineral carbonation of CO2. The first attempt about fate of CO2 in brine (regional aquifer) has been modelled from geochemical point of view.. From the preliminary results of the all above - mentioned options is obvious that for the process of the practical activation of CCS technologies many collisions with hydrogeological, geothermal and land use planning activities and regulations will be necessary to solve
