As a major strategic technology for reducing greenhouse gas emissions and ensuring energy security, carbon capture, utilization, and storage (CCUS) is of great significance to large-scale emission reduction. Most previous CCUS studies have focused on technological implementation, application prospect, and economic analysis. From the perspective of knowledge discovery, it is important to explore the study progress based on existing study achievements, evolution characteristics of study topics over time, and stage-specific findings. This will help researchers gain an overall understanding of CCUS studies and serve to develop an academic study community of CCUS, as well as promote the industry-college-research cooperation in respect to CCUS. Based on the Web of Science (WOS) database platform, the present study conducts a literature review of international CCUS studies from 1989 to 2018 using the bibliometric method. Through the software CitNet-Explorer, this study identifies the core study topics in the CCUS field and explores the evolutionary trends and characteristics of the topics, using visual and cluster analysis methods. According to the H-index-based citation network, this study could track six hot modules within the CCUS field. Consequently, the cutting-edge trends of CCUS studies were predicted.
