Under the increasing demand for safe operation and maintenance of supercritical CO 2 pipeline transportation projects, this paper summarizes the synergistic mechanism of process parameters such as pressure and temperature on pipeline corrosion in current CO 2 transportation pipelines. The critical phenomenon of water content affecting corrosion and the current research status of the intensification of CO 2 corrosion by impurities such as O 2 , SO 2 , NO 2 , and H 2 S on typical pipeline steel corrosion behavior are summarized, aiming to provide theoretical guidance for the risk analysis of pipeline steel corrosion in CCUS engineering in China. Finally, based on practical engineering requirements, it is suggested that in future research, more attention should be paid to the impact of supercritical CO 2 flow characteristics on pipeline corrosion risk.
