Status and perspectives on CCUS clusters and hubs

Abstract
Carbon Capture, Utilization, and Storage (CCUS) refers to the process of capturing and separating CO 2 from emission sources such as energy utilization and industrial processes, or directly from the atmosphere, and transporting it to suitable locations for utilization or storage, in order to achieve long-term storage or conversion of CO 2 . Over the past century of development, CCUS has evolved from a standby technology primarily to becoming a crucial technology for achieving net-zero emissions. Its role in addressing climate change has become increasingly important. In this context, clusters and hubs have become the hot topics in the development of CCUS. By sharing costs and risks, as well as benefits and achievements, clusters and hubs will effectively promote the large-scale application of CCUS. Currently, there are about 25 CCUS cluster or hub projects being researched or constructed worldwide. The Longship project in Norway is a typical hub project and provides valuable insights for global peers. China's three major state-owned petroleum companies are also conducting research on CCUS cluster projects. In the future, multiple CCUS cluster projects will be established in the Bohai Bay Basin, Songliao Basin, Junggar Basin, Ordos Basin, as well as the Yangtze River Delta and the Pearl River Delta regions, providing strong impetus for the development of China's CCUS industry. • The development history of CCS/CCUS has been clarified, which has been divided into four stages. The first stage is the conception stage for CCS originated in 1920s. The CO2 separation technology for natural gas reservoirs had been implemented. The second stage is the formative stage for CCS, in which the basic idea of CCS had been formed. The third stage is the demonstration and application stage, in which the definition of CCS/CCUS has been determined. Some demonstration projects have been established. The fourth stage is the stage of large-scale promotion, in which CCS/CCUS clusters and hubs are under construction or planning. • The comparison of CCUS cluster and hub has been done. The advantages of CCUS cluster and hub have been analyzed, which includes the cost-sharing, the stable operation, the favorable policy, the beneficial commercial mode. • The status of CCUS cluster and hub have been summaried. And the Case analysis on Longship CCS hub in Norway has been carried out, which would guide the development of CCUS cluster and hub in China.
