Abstract: Carbon Capture, Utilization, and Storage (CCUS) represents a critical technological pathway for achieving carbon neutrality targets. It is paramount for the low-carbon transition of the hard-to-abate sectors. Based on the analysis of the current status of CCUS development in China, this paper notes that while progress has been achieved in terms of policy support and the number and scale of demonstration projects, significant challenges persist, including high technological costs, immature business models, incomplete industrial chain planning, and underdeveloped policy and market mechanisms. International analysis indicates a substantial gap between current global and national/regional CCUS deployment scales and the levels required to meet climate objectives. Developed countries have achieved more mature commercial project development through top-level strategies, regulatory standards, fiscal and tax incentives, and market mechanisms. Experiences from leading international projects underscore the importance of policy support, market innovation, industrial chain coordination, technological integration, and international cooperation. Consequently, to promote the scaled-up development of CCUS in China, this paper proposes the following recommendations: advancing R&D for cost reduction and efficiency gains, integrating industrial chains, improving policies, regulations, and market mechanisms, while deepening international cooperation and cultivating a skilled talent pool.
