Research progress of carbon capture utilization and storage technology

Carbon capture, utilization and storage (CCUS), as a key technology to address global climate change, is a powerful tool to achieve the goal of “dual carbon” and has received widespread attention worldwide. This paper summarized the whole CCUS process and its technology and focused on three types of capture including pre-combustion capture, oxy-fuel combustion capture, and post-combustion capture. Among them, the last one is the most mature technology. CO₂ transport methods mainly include pipeline transport, tanker transport and ship transport, among which the first one is the focus of future development. The current development status of CCUS demonstration projects at home and abroad was explained, and the economic, technical and policy factors that restrict its development were summarized. In the future, the focus should be on breaking through technical barriers, developing new high-efficiency and low-energy carbon capture technologies, and accelerating the development of multi-energy complementary coupling utilization models to promote the development of CCUS projects, thereby realizing China's carbon emission strategy.
