Carbon Capture, Utilization and Storage: Technology, Application, and Policy

Global warming has become a major challenge facing human society, with carbon dioxide (CO2) emissions being its primary driver. Carbon capture, utilization, and storage (CCUS) represents a promising technology for mitigating CO2 emissions from industrial and energy sectors. However, challenges such as high energy consumption, lengthy construction cycles, significant costs, and inadequate policy and market mechanisms hinder the widespread adoption of CCUS technology. This paper reviews the potential, applications, and related policies of CCUS technology, highlighting current research progress and obstacles. First, it provides a comprehensive overview of the CCUS technology framework, detailing developments and engineering applications in capture, transport, enhanced oil recovery, and storage technologies. Through global case studies and analysis, the review also examines advancements in CCUS infrastructure and technology strategies, along with operational experiences from major global projects. Second, it delves into the mechanisms, applications, and challenges of CCUS-related technologies, which are crucial for advancing their industrial deployment. It also outlines policy measures adopted by different countries to support CCUS technology development and large-scale deployment. Finally, it projects future directions for CCUS technology and policy development.
