中文摘要: “双碳”目标背景下,亟需深刻了解CO2捕集利用与封存(CCUS)技术及其未来在中国发展的前景,从时间、空间以及技术链3个维度对CCUS的历史演变、现状以及未来发展趋势进行总结与展望很有必要且意义重大。时间维度上,CCUS技术可划分为技术孕育阶段(1950—1980年)、诞生与发展阶段(1980—1995年)、研发与示范阶段(1995—2020年)、实施阶段(2020—2030年)以及商业化阶段(2030—2050年)。空间维度上,CCUS商业化部署水平处于领先地位的国家主要分布在发展时间较长、整体研发水平较高的北美和欧洲地区,此外,中国、澳大利亚,沙特阿拉伯和巴西也进入了先进行列。技术链方面,CCUS技术可划分为3个代际:在捕集环节,第1代捕集技术可应用于电厂,第2代捕集技术面向电力与工业应用,第3代能耗、运行成本以及维护费用均能降低至第1代的50%左右。在输送环节,第1代CO2输送技术建立CO2流动模型,研究扩散规律,控制CO2腐蚀,优选管道材料,评估泄漏影响,开发监测报告核实工具等;第2代CO2输送技术集中于大规模管网开发、标准规范制定;第3代可应用于大规模国家和国际管网。在封存环节,第1代优先发展地质封存共性技术,第2代针对安全监测、风险管理优化,第3代侧重完整监测与补救措施。目前,中国CCUS总体水平处于研发和示范的初期阶段,与其他领先水平国家相比存在一定差距,应加强CCUS领域的国际合作与交流,引进和学习国外CCUS核心技术和实践工程经验,为未来中国大规模全流程CCUS项目的实施做好准备和铺垫。
Abstract:For an in-depth understanding of CCUS and its future development in China, the historical evolution, status and future trend of CCUS were explained from the three dimensions of time, space, and technology chain. In terms of time dimension, from 1950 to 2050, it can be divided into technology incubation phase (1950—1980), formative and development phase (1980—1995), R & D and demonstration phase (1995—2020), implementation phase (2020—2030) and commercialization phase (2030—2050). In terms of spatial dimension, countries in the leading position of CCUS technology are mainly distributed in North America and Europe, where the development time is relatively long and the overall R & D level is relatively high. In addition, Australia, Saudi Arabia, Brazil and China have also entered advanced ranks of CCUS. In terms of technology chain, CCUS technology can be divided into three generations. In the capture section, the first-generation capture technologies can be applied to the power plants; the second-generation capture technologies are oriented to power and industrial plants; the energy consumption, operating cost and maintenance cost of the third generation can be reduced to about 50% of the first generation. In the transportation section, the first-generation of CO2 transport technology breaks through the lows of flow and diffusion, corrosion material control, leakage impact assessment, monitoring report and verification tools, etc.; the second generation focuses on the large-scale pipeline network development and standard formulation; the third generation can be applied to the large scale national and international pipe networks. In the storage section, the first generation prioritizes the development of common geological storage technologies; the second generation focuses on the safety monitoring and risk management and optimization; the third generation focuses on the complete monitoring and remedial measures. The overall level of CCUS in China is in the early stage of R & D and demonstration, and there is a certain gap between China and other leading countries. It is necessary to strengthen international cooperation and exchanges in the field of CCUS, introduce and learn CCUS core technologies and practical engineering experience, and prepare for the implementation of large-scale full-process CCUS projects in China in the future.
