It has been in creas ingly real ised that geo log i cal stor age of CO 2 is a pro spec tive op tion for re duc tion of CO 2 emis sions. The CO 2 geo log i cal stor age po ten tial of sed i men tary bas ins with the ter ri tory of Slovakia, the Czech Re pub lic, Po land and the Bal tic States is here as sessed, and dif fer ent stor age op tions have been con sid ered. The most pro spec tive tech nol ogy is hydro dy namic trap ping in the deep sa line aqui fers. The uti li sa tion of hy dro car bon (HC) fields is con sid ered as a ma ture tech nology; how ever, stor age ca pac i ties are lim ited in the re gion and are mainly re lated to en hanced oil (gas) re cov ery. Pro spec tive res er voirs and traps have been iden ti fied in the Dan ube, Vi enna and East Slovakian Neo gene bas ins, the Neo gene Carpathian Foredeep, the Bo he mian and Fore-Sudetic Up per Pa leo zoic bas ins, the Me so zoic Mid-Pol ish Ba sin and the pericratonic Pa leo zoic Bal tic Ba sin. The to tal stor age ca pac ity of the sed i men tary bas ins is es ti mated to be as much as 10,170 Mt of CO 2 in deep sa line aqui fer struc tures, and 938 Mt CO 2 in the de pleted HC fields. The uti li sa tion of coal seams for CO 2 stor age is re lated to the Up per Silesian Ba sin where CO 2 stor age could be com bined with en hanced re cov ery of coal-bed meth ane.
