Special Issue Information

Dear Colleagues,

To combat the detrimental impacts of climate change and meet the obligations outlined in the 2015 Paris Agreement, CO2 Capture, Utilisation, and Storage (CCUS) has emerged as a crucial technology with significant potential for achieving climate targets. CCUS technology achieves the resource utilization of captured CO2 and stores it in strata such as oil/gas reservoirs and salinity aquifers. However, there are still many challenges involved in several key parts of CCUS, including low-cost carbon capture, long-distance pipeline transport, CO2-EOR, CO2-ECBM/shale gas, and long-term safe storage. There is an urgent need for research and development in order that we implement CCUS-related technologies.

In this Special Issue, contributions to recent advances in CCUS technologies are welcome. Topics include, but are not limited to

  • New theories and methods for CCUS;
  • Laboratory experiments and numerical modelling of CCUS;
  • Economic evaluation and field practices of CCUS;
  • The environmental impact of CCUS projects;
  • CO2 monitoring

CO2 geological storage combined with deep saline water recovery technology (CO2-EWR) is one of the most effective ways to reduce carbon emissions. Due to the complex structural features, it is difficult to use CO2-EWR technology in Huaiyin Sag, Subei basin, East China. In this study, the multi-source information superposition evaluation technology of GIS was utilized for the selection of CO2 storage sites and water displacement potential target areas in this area, which mainly focused on the sandstone reservoirs of Cretaceous Pukou Formation. Based on the results, a three-dimensional injection–extraction model was established. Various scenarios with different production/injection well ratios (PIR) were simulated. Research has shown that the suitability of the surrounding site of Huaiyin Power Plant can be divided into two levels: relatively suitable and generally suitable; the area in the generally suitable level accounts for more than 80%. At a PIR of 1, CO2 is distributed asymmetrically, whereas at PIRs of 2 or 4, CO2 is distributed symmetrically. When the number of production wells is constant, a higher injection rate results in a faster expansion rate of the CO2 plume. This means that the time taken for the CO2 plume to reach the production wells is shorter. Reservoir pressure increases rapidly after more than 60 years of CO2 injection at lower PIR values, while at higher PIRs, reservoir pressure eventually stabilizes. Higher PIR values correspond to higher gas saturation, indicating a greater capacity for CO2 sequestration with more producing wells. When PIR = 4, the total CO2 injection increased by 55.73% compared to PIR = 1. However, the extraction of saline decreases with an increase in the number of producing wells, resulting in a decrease in replacement efficiency. This study provides a theoretical basis and technical support for the implementation of large-scale CO2-EWR engineering and technology demonstration in this region. Full article
