Abstract

Carbon dioxide geological storage represents a key segment of the carbon capture and storage system (CCS) expected to significantly contribute to the reduction of its emissions, primarily in the developed countries and in those that are currently being industrialised. This approach to make use of the subsurface is entirely new meaning that several aspects are still in research phase. The paper gives a summary of the most important recent results with a short overview the possibilities in the Republic of Croatia. One option is to construct underground carbon dioxide storage facilities in deep coal seams or salt caverns. Another would be to use the CO2 in enhanced oil and gas recovery projects relying on the retention of the carbon dioxide in the deep reservoir because a portion of the injected gas is not going be produced together with hydrocarbons. Finally, the greatest potential estimated lies in depleted hydrocarbon reservoirs with significantly reduced reservoir pressure, as well as in the large regional units - layers of deep saline aquifers that extend through almost all sedimentary basins.
