Abstract
CO2 geological utilization and storage is considered as an effective approach to deeply cut anthropogenic CO2 emissions. It is vital to enhance the amount of CO2 stored in the subsurface, at the same time to ensure safe and long-term subsurface storage of CO2 without any CO2 leakage. Science and engineering research in modeling concepts, experimental approaches, safety assurance and emerging CO2 geological utilization and storage technologies have driven the advancement of CO2 geological utilization and storage in recent years. In order to encourage communication and collaboration in CO2 geological utilization and storage research worldwide, a Sino-German joint symposium titled “Opportunities and Challenges in CO2 Geologic Utilization and Storage” was organized in Wuhan and Stuttgart from February 22 to 24, 2023, bringing together experts from China, Germany, and other countries. The symposium was jointly organized by Institute of Rock and Soil Mechanics, Chinese Academy of Sciences and Institute for Modelling Hydraulic and Environmental Systems, University of Stuttgart with financial support from the Sino-German Center for Research Promotion. A two-site hybrid meeting was held (participants in China met in Wuhan, participants in Germany met in Stuttgart, and other participants joined the meeting online), attracting more than 100 participants from around the world. The latest studies in the field of CO2 geological utilization and storage were presented at the symposium.
