This chapter presents a comprehensive optimization model for designing a land-sea CO2 pipeline network to support China’s coal power industry in achieving carbon neutrality through CCUS (carbon capture, utilization, and storage). The model identifies suitable coal-fired power plants for retrofitting and evaluates CO2 storage potential at various sites across the country. It aims to minimize the total cost of capture, transport, and storage while considering social, geographical, and geological factors. The study finds that, under a high-carbon capture scenario, China needs to build 414 pipelines spanning 23,876 km, with an average length of 58 km and diameters ranging from 8 to 36 in. . Five major onshore pipeline clusters are planned in key basins such as the Songliao Basin and the Ordos Basin, while offshore storage opportunities are identified in regions like Bohai Bay and the Pearl River Mouth Basin. The economic analysis reveals that capture costs dominate at 65.4% of the total, with transport and storage costs accounting for 19.3% and 15.3%, respectively. The total unit cost for onshore storage is 57.34 dollars per ton of CO2, compared to 80.44 dollars per ton for offshore storage. The chapter recommends prioritizing pipeline cluster construction in major basins and initiating offshore storage demonstration projects in Bohai Bay to advance CCUS infrastructure development.
