A Pioneering Step Towards a Greener Future and Achieving Dual Carbon Goals

A Step Towards a Greener Future

China is taking significant strides in its commitment to environmental protection through the development of innovative technologies like carbon capture, utilization, and storage (CCUS). In the Liaohe Oilfield, located in Panjin, Liaoning province, PetroChina is implementing this technology to address the challenge of carbon emissions.

The process involves capturing carbon dioxide produced during oil extraction and injecting it into underground storage over 3,000 meters deep. This not only reduces emissions but also enhances oil recovery. Since December 2022, the 229 Block CCUS cyclic injection station has successfully injected nearly 50,000 metric tons of liquid carbon dioxide.

By 2026, the facility aims to store 100,000 tons of carbon dioxide annually, with a total capacity of 2.36 million tons. This is equivalent to planting a forest of 950,000 trees, highlighting the project's significant contribution to carbon reduction.

The initiative aligns with China's ambitious dual carbon goals, announced by President Xi Jinping in 2020, to peak carbon emissions before 2030 and achieve carbon neutrality by 2060. The project's success demonstrates China's commitment to achieving these goals through technological innovation and sustainable development practices.

The geological conditions of the 229 Block are ideal for carbon storage, with its high-density rock formations and firm cap rock ensuring safe and stable storage without leakage. This project serves as a model for other oilfields and industries to adopt CCUS technology, paving the way for a greener future.
