基于知识图谱的中国碳捕集利用与封存技术研究进展与启示OA北大核心CSTPCD

Carbon dioxide capture,utilization and storage(CCUS)technology is considered one of the most significant negative carbon technologies to reduce global carbon dioxide emissions.Achieving carbon neutral-ity in China is inseparable from the large-scale promotion and application of CCUS technologies.To compre-hensively grasp the current status and development trend of CCUS technology research in China,this paper,from the literature exploration and policy-driven perspective,utilizes bibliometric tools to statistically analyze and mine the information of 1255 literature samples published based on the core database of CNKI from 2000-2021.After data cleaning and synonym conversion,the current research status and future develop-ment trends of CCUS technology are systematically reviewed and prospected.The results show that:①CCUS core literature presents a"wave-like"upward trend as a whole,and the development stages can be di-vided into the initial stage of research,the initial growth stage,the fluctuating development stage and the rapid development stage;② CCUS technology is a multidisciplinary field with characteristics of interdisciplin-ary and cross-industry integration,involving disciplines such as environmental science,chemical engineering,management science,and geology.There are certain barriers between disciplines,and a stable set of disci-pline journals has yet to be formed;③ The main research forces of CCUS technology are concentrated in uni-versities,research institutions,and energy resource-based enterprises.The cooperation between teams is relatively scattered and needs further strengthening;④ Keyword frequency analysis reveals diverse research hotspots in CCUS technology,including carbon dioxide capture technology,storage technology,carbon diox-ide enhanced oil recovery,economic evaluation,and business models,carbon dioxide utilization,leakage and monitoring,pipeline transportation,numerical simulation,and risk management;⑤ The thematic evolution of CCUS technology research is continuously evolving,with a clear policy orientation.Policy-driven incen-tives play a positive role in the development of CCUS technology in China,but the regulatory framework for CCUS policies and regulations needs further improvement.This paper suggests focusing on disruptive tech-nology research and innovation in CCUS,breaking down barriers between different disciplines,and building a localized theoretical framework for CCUS.The systematic review of the current state of CCUS technology development in this paper contributes to enhancing public awareness in this field.It also helps government,enterprises,and researchers to comprehensively understand and grasp the research hotspots and frontier trends in the field of CCUS technology in China,providing reference basis for the continued advancement of CCUS technology and rigorous decision-making in China.
