Challenges to the carbon dioxide capture and storage (CCS) technology

Carbon dioxide Capture and Storage (CCS) technology, which is one of the technologies against global warming, applied to the separation and capture Of CO2 gas and finally storage underground is attracting attention. There are several technologies being developed for CO2 separation and capture, namely the chemical absorption method, physical absorption method, adsorbing separation method and membrane separation method. These are being developed to apply to postcombustion capture, oxyfuel postcombustion capture, etc. With regard to the CO2 storage technologies, the method of injection into an aquifer is being developed as the major one, and studies on issues for actual technical application are being conducted in the form of engineering study on the assumed model area. In this report, our expectations toward actual application of the CCS technology, the trends of the CCS technology and other related matters are introduced.
