China has successfully converted a long-distance crude oil pipeline to transport carbon dioxide, potentially lowering costs and speeding up the expansion of carbon capture and storage networks worldwide, with implications for decarbonising heavy industry.
China has completed a pilot conversion of a long‑distance crude oil pipeline to carry carbon dioxide to an onshore oilfield, a development industry observers say could materially lower the cost and timescale for scaling carbon transport networks needed by carbon capture, utilisation and storage (CCUS) projects.
According to state‑owned China Oil and Gas Pipeline Network Corporation (PipeChina), the trial put captured CO2 into an oilfield in Henan province via a roughly 27‑kilometre (17‑mile) line earlier this month. PipeChina described the exercise as “replicable and scalable,” arguing that adapting existing hydrocarbon trunks can avoid much of the expense and delay involved in laying new, dedicated CO2 routes. Industry figures cited in reporting indicate repurposing can cut upfront investment by between 40% and 80% and shorten construction schedules by up to 60% compared with greenfield pipelines.
The pilot feeds CO2 destined for enhanced oil recovery (EOR), a dual‑benefit application that boosts crude output while trapping greenhouse gas underground. For China, where major emission sources are clustered in eastern and coastal industrial zones but storage and utilisation opportunities concentrate in the north and west, long‑distance transport solutions are essential if CCUS is to move beyond isolated demonstrations.
The Henan trial sits alongside parallel, larger builds. Provincial and company announcements show activity accelerating in the northeast: CNPC Jilin Petrochemical began construction on a multi‑phase supercritical/dense‑phase CO2 pipeline in April. According to the Jilin provincial government, the first phase covers about 282.26 kilometres and is designed to carry roughly 3.3 million tonnes of CO2 a year, with the full project approaching 400 kilometres and aiming to act as a regional CO2 backbone once commissioned, targeted for 2026. Earlier coverage had referenced a separate Jilin corridor of about 249 miles expected to sequester as much as four million tonnes annually; the differing figures reflect distinct project phases and capacity estimates disclosed by local authorities and developers.
Other large CCUS operations are already accruing operational experience. PetroChina reports the Xinjiang oilfield complex has injected more than two million tonnes of CO2 cumulatively, underlining that inland basins are becoming active hubs for both production‑focused EOR and long‑term geological storage. Offshore experimentation has also advanced: state engineering groups have developed floating production, storage and offloading units equipped with CO2 capture systems, demonstrating capture can be integrated with complex upstream platforms while recovering power from exhaust heat.
For industrial decarbonisation practitioners, China’s blended approach , converting legacy pipelines where feasible, while constructing purpose‑built dense‑phase networks where scale demands it , offers an instructive model. Repurposing leverages right‑of‑way, welding and corrosion‑management expertise already embedded in the pipeline sector and reduces permitting hurdles; dedicated supercritical lines, by contrast, are engineered for higher throughput and the specialist compression and materials required for long‑haul, dense‑phase CO2.
Nonetheless, significant technical and regulatory hurdles remain. Operators must validate material compatibility, leak detection and monitoring regimes, and safety protocols for a substance with different thermophysical behaviour from hydrocarbons. Integrating capture and transport with electricity systems and industrial point sources also raises questions about coordination, pricing and long‑term contractual frameworks that will determine whether CO2 moves reliably from emitters to storage. In addition, reliance on EOR as an early market for CO2 can complicate net‑emissions accounting unless projects demonstrate robust permanence.
China’s mix of pilots and large‑scale pipelines is already influencing project economics and supply‑chain planning beyond its borders. According to observers quoted in coverage, if conversions prove durable and scalable, they could reduce barriers for countries with dense, ageing oil‑transport networks seeking to build CO2 corridors quickly and cost‑effectively.
For industrial users and infrastructure investors focused on decarbonising heavy industry, the key lessons emerging from China’s programme are pragmatic: retrofit where it materially lowers capital intensity and time to operation; invest in purpose‑designed CO2 transmission where capacity and reliability demand it; and couple transport plans with rigorous monitoring, regulatory clarity and transparent accounting so that capture and storage deliver verifiable emissions reductions rather than primarily supporting additional fossil production.
As China expands both retrofit pilots and dedicated CO2 mains, the sector will watch whether those projects can be replicated at scale with consistent safety and permanence outcomes. For corporates planning CCUS deployment, the evidence from Henan, Jilin and Xinjiang suggests an increasingly diverse set of transport options is becoming operationally and commercially credible, creating new pathways to decarbonise process‑intensive industries while reshaping the economics of long‑distance CO2 logistics.
