Status and perspectives on CCUS clusters and hubs

Carbon Capture, Utilization, and Storage (CCUS) refers to the process of capturing and separating CO2 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 CO2. 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.
