Abstract: Carbon capture, utilization, and storage (CCUS) is a bottom line technology for achieving carbon neutrality, which has attracted widespread attention from the international academic community. The research trends in this field were systematically summarized by bibliometric and keyword clustering analysis, based on 1 519 literature from CNKI and WOS databases from 2000 to 2024. The research shows that the average annual growth rate of global publications was 12%. China reached its peak (557 articles) in 2023 after starting in 2006, which focused on "saltwater", "numerical simulation", "carbon neutrality" and "storage potential". While the international research tends to favor engineering practices such as "sequstration", "injection" and "capacity". The key technological progress was reflected in four aspects. (1) The static volume method and capacity calculation equation were widely used to quantify reserves. The global storage potential assessment framework has preliminarily formed. (2) A complete reservoir rating system has been established, with deep saline reservoirs becoming the mainstream target for storage, and other new types of reservoirs being constantly explored. (3) The numerical simulation multi field coupling technology has significantly improved, which greatly enhanced the reliability of reservoir evaluation and potential assessment. Currently, various numerical simulators such as MIN3P and TOUGH have been developed and applied in practice. (4) The environmental risk assessment mechanism was gradually improved, and leakage warning was achieved through four-dimensional earthquake monitoring and unmanned aerial vehicle remote sensing. However, geological sequestration of carbon dioxide still faces challenges such as uncertainty in reservoir parameters leading to fluctuations in storage efficiency, immature long-term monitoring technology causing leakage risks, and high environmental monitoring costs, which need further development. The research has guiding significance for the development direction of carbon dioxide geological sequestration field and could provide references for future research focus of carbon dioxide geological sequestration.
