China's first offshore carbon capture and storage demonstration project was put into operation on Thursday in the eastern waters of the South China Sea, said its operator China National Offshore Oil Corporation.

The project will further facilitate China's carbon peak and neutrality goals, marking a milestone that China has a full set of technologies and equipment for offshore carbon capture, treatment, injection, storage and monitoring, while filling the gap in offshore carbon storage technology, said the company.

The carbon dioxide captured during oilfield development was injected 800 meters under water close to the Enping 15-1 platform, Asia's largest offshore oil production platform. The project is expected to store 300,000 metric tons of carbon dioxide each year, it said.
