Abstract: Carbon capture, utilization and storage (CCUS) technology is the most effective and economical method to achieve China's dual carbon goals and mitigate global warming. The importance of CO₂ pipeline transportation as an intermediate link between capture, storage, and utilization in terrestrial CCUS projects is self-evident. The current CO₂ pipeline construction projects in China, the phase state of pure CO₂, CO₂ corrosion mechanism, supercritical CO₂ transport pipes and their corrosion status are reviewed. The effects of impurities on the phase state, properties and corrosion mechanism of CO₂ are collated. Finally, the urgent problems and research prospects in China in terms of CO₂ transport characteristics and corrosion behavior of its transport pipes are presented.
