    and to influence climate change in the world. Thus, China's fossil fuel-dependent power sector needs to reduce CO2 emission. Carbon capture and storage (CCS) is one of the solutions to decrease CO2 emission, and geological CO2 sequestration (GCS) is recommended considering its high potential and effectiveness. In this study, the efforts to implement geological CO2 sequestration in China are reviewed, and current technical issues are addressed.

    , and hydrate bearing sediments are introduced with the data collected from the pilot, demonstration, and large-scale projects in China. Among potential sites, saline aquifers have been considered as sites with the highest potential for CO2 storage in China because of their enormous capacity. Main trapping mechanisms including structural-, capillary residual-, solubility- and mineral-trappings support saline aquifers as the most possible CO2 storage site. Also, CO2 injectivity and CO2-brine displacement efficiency in saline aquifers are explored to improve the efficiency of CO2 injection with current techniques including visualizing experimental testing method for two-phase immiscible flow such as microfluidic model and X-ray computed tomographycomputed tomographySubject Category: Techniques, Methodologies and Equipment
