Research Progress and Hotspot Analysis of Carbon Capture, Utilization, and Storage (CCUS): A Visual Analysis Using CiteSpace

Abstract

AbstractThe issue of global climate change has become increasingly prominent. The reduction of fossil energy consumption and the reduction of greenhouse gas emissions have attracted more and more attention from countries. Carbon capture, utilization, and storage (CCUS) technology is considered to have the synergistic effect of achieving large-scale greenhouse gas emission reduction and low-carbon utilization of fossil energy. It is one of the important technological choices for the global response to climate change in the future. It has attracted governments and enterprises from all over the world and the high attention of the academic community. This paper screened out 1890 scientific articles related to global CCUS from the Web of Science Core Collection and used the CiteSpace to analyze the knowledge graph of the papers since 2011. The paper visually displays the most productive institutions, authors, and sources in the CCUS research. In addition, the paper explains how research subjects have changed over time and analyzes research frontiers. The results show that: (1) CCUS research has accelerated globally in the past ten years, with the United States, the United Kingdom, and China ranking the top three. (2) Research hotspots mainly focus on engineering, energy and fuels, engineering chemistry, engineering environment, science and technology, green sustainable technology, environmental science, and ecology. (3) CCUS has become a multidisciplinary research, in which all research subjects related to CCUS have been cited and correlated. In general, this research is helpful for policy guidance and follow-up research.KeywordsCarbon capture, utilization and storage (CCUS)VisualizationCiteSpaceBibliometric methods
