On April 27, CNPC Jilin Petrochemical Co kicked off the first phase of China's largest and longest supercritical/dense-phase carbon dioxide (CO₂) pipeline in Songyuan, Northeast China's Jilin province.

The pipeline will span nearly 400 kilometers and connect major cities like Changchun, Jilin, Songyuan, and Siping, with the first phase covering 282.26 km and designed to transport 3.3 million metric tons of CO₂ annually.

The project applied advanced technologies such as centrifugal CO₂ compressors and integrates CNPC's full carbon value chain. This reduces emissions while also boosting oil output.

Once it becomes operational in 2026, the pipeline will serve as the main CO₂ network for carbon emitters and users in Jilin, accelerating the province's green transformation.

As part of China's national dual carbon goals, the project also marks a major milestone in the development of CCUS (carbon capture, utilization, and storage) technologies, contributing to cleaner energy and industrial sustainability nationwide.
