In recent years, carbon capture, utilization and storage (CCUS) technology has attracted worldwide attention. In order to understand the latest hotspots and development trends in the field of carbon capture, utilization and storage (CCUS), through the Web of Science core collection database, advanced search was conducted with the theme of “CCUS”. A total of 6753 English literatures published by global scholars from 2000 to 2024 were selected, and visual analysis software VOSviewer, HistCite and Biblioshiny were used to analyze the annual number of publications, subject distribution, journal distribution, research countries, research institutions, research hotspots and development trends. The innovation of this research is reflected in revealing the global CCUS technology research pattern and development direction: for the first time, it quantitatively points out that although China started late, the number of achievements has jumped to the first place, breaking through the dominant mode of traditional technology power; three frontier directions in the future are proposed : energy transformation coupled with geological energy storage, molecular dynamics-enabled storage safety assessment, and economic feasibility optimization path. Breaking through the existing single carbon storage research framework, an integrated technology system of ’capture-utilization-energy storage’ is constructed. In particular, through the interdisciplinary integration of molecular dynamics, it provides atomic-scale theoretical support for deep geological storage, promotes the transformation of CCUS from engineering verification to intelligent design, and fills the theoretical gap of large-scale application.

As coastal ultra-deep mine shafts advance to greater depths, shaft lining concrete may experience sustained humid–hot conditions. Elevated temperature is induced by geothermal heat and early-age hydration heat, while high humidity is maintained in water-rich underground environments, which can compromise long-term performance. Such late-age deterioration may increase maintenance demand and pose safety concerns for ultra-deep shaft construction and long-term service. This study experimentally evaluates a high-strength shaft lining concrete designed with a composite cementitious system and cured at 40, 60, and 80 °C (95% RH) for 30–180 days, considering the engineering scenario of the 2500 m shaft at the Sanshan Island Gold Mine. The selected temperature range was determined based on in situ temperature monitoring in the target shaft. P-wave velocity measurements and uniaxial compression tests were conducted, while acoustic emission (AE) monitoring and energy evolution analysis were used to interpret damage progression. P-wave velocity decreased with curing temperature, with the most pronounced reduction at 80 °C. Compressive strength increased at early ages and then declined at later ages; by 180 d, the strength loss relative to the peak level is more pronounced at higher temperatures. AE results show four typical damage stages, with activity increasingly concentrated near peak stress as temperature and age increase. AF–RA analysis indicates tensile cracking dominates, with a slight increase in shear-related events at higher curing temperatures and longer ages. Energy analysis further confirms that most input energy is stored as elastic strain energy prior to peak stress, and higher curing temperatures increase the proportion of input energy stored elastically, implying a higher tendency toward brittle failure. These results suggest optimizing curing regimes and toughness-enhancement strategies for durable shaft infrastructure.
