Operations research is required to carry the Carbon Capture and Storage (CCS) efficiently and economically against uncertainty in geological conditions and system troubles to terminate CO2 storage. In this study, CCS systemperformance has been investigated by numerical simulations for estimation error in permeability distribution of the layer, and economic evaluations on troubles assumed to make terminate CO2injection. The CO2buffer, such assphere gas tanks, should be installed to store CO2onthe process after its capture. If CO2 buffer is not included in the system, captured CO2 may be released to the atmosphere when a trouble on transportation or injection processes occurs.Thelarger size of CO2 buffer volume can be more able to withstand against long-term trouble.However, the larger buffer volumeneeds higher initial cost for constructing. Several simulations have been conductedon its system performance with and without CO2 buffer in the system. OptimumCO2 buffer volume has been presented based on economical evaluations for a commercial CCS model.
