The economics of CO2 capture

We have conducted a comparison of published studies that analyzed the economics of capturing CO2 from the flue gas of power plants. For these studies, we have put the results on a common basis and conducted a sensitivity analysis. Three types of power plants were reviewed: pulverized coal plants, integrated gasification combined cycle plants, and natural gas combined cycle plants. Based on our analysis, we summarize the costs of CO2 capture using today's technology. In addition, we have identified where technological improvements can significantly lower costs. We conclude that with new developments, CO2 capture and sequestration can become a cost-effective mitigation pathway.
