[Objective] Carbon capture, utilization and storage (CCUS) technology is an effective way to realize the dual-carbon strategy and has broad application prospects. Long distance CO2 pipeline transportation is an important part of CCUS technology. For the safe operation of the pipeline, the corrosion in the pipeline is the key problem threatening the safety of CO2 pipeline. [Methods] This paper focused on the corrosion of supercritical CO2 as the main phase, reviewed the research progress of supercritical/dense-phase CO2 pipeline corrosion, analyzed the existing problems between the relevant research results, and prospected its future development direction. [Results] This paper focused on the factors affecting the corrosion of CO2 pipelines in supercritical and dense phases, expounded the effects of working parameters such as temperature and pressure on the degree of miscibility of water and CO2, explained the reasons for the conflicting results of existing research results, and summarized the mechanism of the influence of the main impurity gases in the pipeline on CO2 corrosion. The influence of the structure, density and integrity of the corrosion product film on the corrosion kinetics under different CO2 phase states was analyzed, and the corrosion characterization technology suitable for supercritical CO2 environment was summarized. The corrosion rate prediction model suitable for thin liquid film in supercritical CO2 environment was summarized. [Conclusion] In order to achieve the safe and stable operation of CO2 transport pipeline, this paper points out that the problems to be solved in the current research on the corrosion of supercritical - dense phase CO2 transport pipeline include: the establishment of standard experimental procedures; The influence of impurity coupling on corrosion mechanism and corrosion product membrane structure; The protective effect of the corrosion product film on the substrate was quantitatively described. Measurement and analysis of corrosion electrochemical parameters in thin liquid film in water saturated CO2 phase; A prediction model of supercritical/dense-phase CO2 corrosion under coupled multi-impurity interactions was established.
