This paper presents the result of analyzing the effects of carbon dioxide (CO
2) capture and storage systems (CCS) combining
with coal bed methane (CBM) utilization on energy systems of China up to 2050 by using GOAL model. The model is a
linear programming optimal method, which covers the whole energy systems of seven Asian countries from mining,
transportation, and conversion to final demand. The authors assume seven-scenarios which consist of a Base scenario and six
CO
2 reduction scenarios of with CCS and without CCS with 10%, 20%, and 30% reduction of CO
2 emission per capita
against the level of Base scenario from 2010. Based on the result of the analysis, It is clarified that integrated gasification coal
power plant (IGCC) with CCS is the most economic technology among assumed technologies, such as pulverized coal power
plant (PC), IGCC and natural gas combined cycle power plant (NGCC), under the constraint of CO
2 emissions in China. In
the case of non-CCS, the share of NGCC in 2050 becomes 10%, 50% and 68% in total electricity supply (TES). Introducing
CCS can reduce the amount of installation of NGCC and the share of IGCC with CCS in 2050 becomes 7%, 15% and 22%
in TES respectively.
