Abstract：Based on the Web of Science Core Ensemble database,this paper presents a systematic analysis of the literature on coupled carbon capture,utilization and storage(CCUS)from global power plants and coal chemical plants for the period 2000-2023.The main findings show that:i)From the perspective of publication volume and trend,the United States has been in the leading position in the research of CCUS technology for coupling power plants and coal chemical plants,in which Carnegie Mellon University has the highest H-index and average cited frequency,and has high international influence and discourse power in this field.Although China's number of papers issued is relatively high,the H-index and average cited frequency are low,and the influence of literature still needs to be improved.ii)In terms of international co-operation,the United States,China and the United Kingdom are the main co-operation targets among countries,and the leading countries in CCUS technology continue to stimulate the progress of CCUS technology.iii)From the point of view of research hotspots,carbon capture and storage,biomass energy carbon capture and storage technology(BECCS)and renewable energy substitution are the focus of research in this field.In recent years,the heat of keywords such as BECCS,decarbonization and biomass has also risen rapidly,and CCUS technology combined with bioenergy is considered to be a key technological pathway to achieve CO2 emission reduction targets,Research on the technical economics of CCUS has also become a key research direction for scholars.
