38 COCLUSIONS There is a huge effective CO2 storage capacity in the Baltic basin saline aquifers The storage capacity of identified structures is 185 Mt The practical storage capacity is 30 Mt Storage and EOR potential of oil fields is negligible International Baltic cooperation would be a prospective solution, agreement on CCS activities between the Baltic countries is needed
