Optimal selection of different CCS technologies under CO reduction targets.

In China, carbon capture and storage (CCS) is recognized as one of the most promising technologies through which to achieve a large reduction in CO emissions in future. The choice among different CCS technologies is critical for large-scale applications. With the aim of developing instructive policy suggestions for CCS development, this study proposed an interval programming model to select the optimal CCS technology among the different CCS technologies available in China. The analysis results indicate that the selection of CO capture technologies should be based on the actual situation of the project and industry being targeted. If the government implements mandatory CO emission reductions, storage in deep saline aquifers is the optimal choice for CO sequestration when oil prices are low and the number of available CO emission permits is large. In contrast, enhanced oil recovery is the optimal choice when oil prices increase and the availability of CO emission permits decreases. It is critical that the government reduce the operating cost and the cost of CO capture in particular. [ABSTRACT FROM AUTHOR]
