Abstract Carbon capture, utilization and storage (CCUS) may play an important role in China's long-term carbon emissions reduction in which coal is the main energy source. However, there has been little research on the need for pipeline networks for CCUS in the Chinese Mainland. The CO₂ pipeline networks and the economic feasibility of which for large-scale CCUS use were analyzed using a static source-sink matching model based on the general algebraic modeling system(GAMS) for the Chinese mainland. Most pipelines should run from south to north, while East China and North China have good structures for CCUS implementation. CO₂ geological storage can produce 23 Mt/a crude oil through CO₂ enhanced oil recovery (CO₂-EOR), while 4.9×10¹⁰ m³/a natural gas can be produced by CO₂ enhanced coal bed methane (CO₂-ECBM), which will lead to an economic benefit of 7.8×10¹⁰ RMB/a. When the amount of CO₂ in the CCUS is increased from 288 Mt/ato 2 886 Mt/a, the unit CO₂ transportation cost is 7-12 RMB/t. The required total pipeline length will be 5.0×10⁴ km for a CO₂ capture rate of 2 886 Mt/a.
