In recent years

carbon capture

utilization and storage(CCUS) technology has attracted worldwide attention. By using the bibliometrics method

this paper carries out systematic statistics and analysis on the scientific literatures related to CCUS technology from 2000 to 2020 in the Web of Science database. The main statistical results show that

the research on CCUS field in the United States is earlier and has been in the leading position for a long time since then. Although China's number of paper issued and H-index of the papers are relatively high

the average cited frequency of each article is low. Among the major global publishing institutions

the US Department of Energy

Chinese Academy of Sciences and Imperial College London have far higher research strength and investment in CCUS technology than other institutions

with the number of publication accounting for 10.01% of the total. From the perspective of cooperation between countries

the United States has been the main object of cooperation among countries. However

with the passage of time

the aggregation of cooperation among countries gradually decreases

and the gap between countries in the field of CCUS technology decreases. In recent years

the aggregation appears again. It can be seen from the change of keywords over time that

in addition to CCUS technology

"CO_2 capture"

"CO_2 transportation" and "CO_2 storage" has always been the focus of CCUS research. In recent years

studies on CO_2 utilization ways and utilization methods have been increasing gradually. In this stage

the heat of keywords such as "bioenergy"

"negative emissions" and "bioenergy with carbon capture and storage(BECCS)" has been rising rapidly

and the heat of economic research on CCUS technology has also been rising continuously. "CO_2 utilization"

"negative emission technology" and "economic of CCUS" will continue to become the future research hotspots in the field of CCUS.
