CCUS技术走向规模化应用

Group 1 - The global carbon capture, utilization, and storage (CCUS) technology is entering a large-scale application phase, with the number and scale of projects rapidly increasing, particularly in hard-to-decarbonize industries like refining and biomass power generation [1] - The oil and gas industry has identified CCUS as a crucial strategic direction for energy transition and the establishment of a new energy system, supporting clean, low-carbon, and stable supply of fossil energy [1] - In China, over 120 CCUS demonstration projects have been put into operation or are under planning, with a total carbon capture capacity exceeding 6 million tons per year [1] Group 2 - Various carbon capture technologies, including direct air capture, are rapidly developing in China, with industrial application conditions being met [2] - A comprehensive technical system for CO2 capture, transportation, and storage has been established, with 278,000 tons of CO2 injected in pilot experiments across 59 blocks [2] - Future CCUS industry development models may include creating multiple oil recovery and storage centers around oil and gas basins or developing CCUS layouts based on regional economic levels and industry competition [2] Group 3 - CCUS technology is not only key for low-carbon utilization of fossil energy but also an essential component for achieving carbon neutrality goals [3] - The first marine CO2 storage demonstration project in China can store 300,000 tons of CO2 annually, with a cumulative capacity of 1.5 million tons, equivalent to planting approximately 14 million trees [3] - Challenges in marine CO2 storage include higher costs for seabed drilling and surveying, leakage risks, and the need for advanced monitoring technologies [3]
