The development of Carbon Capture Utilization and Storage (CCUS) research in China: A bibliometric perspective

摘要

Carbon Capture, Utilization and Storage (CCUS) is considered a critical carbon dioxide reduction technology for climate change mitigation. More recently, it has been attracting significant attention from the Chinese government, industry and academia in relation to its research, development and deployment. This paper screens 1,202 unique scientific articles from Web of Science related to China's CCUS and employs Citespace to conduct a knowledge mapping of the domain. The results show that the number of publications have increased and CCUS has become a multidisciplinary area of study. The paper visually demonstrates the most productive institutions, main authors, and primary sources of China's CCUS research domain. Moreover, the paper explains how the research topics have changed over time and discovers the current research frontiers including "pipeline", "shale gas" and "steel". Of significant interest is the finding that China's CCUS research progress appears to be directly related to the increasing policy support through China's five-year planning process. However, research regarding public perception, financial mechanisms and appropriate business models for CCUS deployment is found to be less prevalent. Recommendations to improve research in these areas are provided from the perspective of government intervention. This paper also highlights the importance of continued government support for CCUS as part of the national development strategy for carbon emissions reduction and transitioning towards a low carbon future.
