AbstractCCS is regarded as an important and strategic technology option to reduce CO2 emission, and has received tremendous attention around the world. Guangdong, as the largest economic and energy-consuming province in China, is necessary to take CCS as an important option to reduce its future CO2 emission. This paper presents the partial outcome of the first CCS-related research in Guangdong, which is aiming for preliminary assessment on the feasibility of CCS development in Guangdong. The main objective of the study is to characterize the industrial CO2 emissions and understand its CCS prospects. Coal-fired power plants in Guangdong are the major point sources, contributing to more than 90% of CO2 emissions from the electric power generation. The power plants are mainly located in the Pearl River Delta, while the newly built and projected large plants are mainly located in eastern coastal zone, which provides a great potential for CO2 capture. For the storage potential, there are six sedimentary basins in or around Guangdong with effective storage capacity of 568 GtCO2. Since the onshore storage capacity in Guangdong is limited, the northern portion of the Pear River Mouth Basin (PRMB) was considered the most promising choice for Guangdong to storage CO2. By considering the distance between source and sink, technology maturity, land resources and other factors, it can be concluded that in the short term the power plants under construction and projected located in the eastern coastal areas will be the most promising resources for CO2 capture and the corresponding storage sites are the existing oil/gas fields which located in the northeast of PRMB. But in the long term, as technologies and the international carbon market mature, the extensively retrofitting of existing coal-fired power plants in the Pearl River Delta region with CO2 capture will become possible. In order to promote the development of CCS in Guangdong, more basic investigation and policy research are necessary in the coming years.
