China National Offshore Oil Corporation announced that China's first offshore Carbon dioxide storage (CCS) demonstration project officially put into use.

The project is a carbon reduction supporting project of the Enping 15-1 oilfield group. The Enping 15-1 oil field is located in the Pearl River Mouth Basin, about 190 kilometers southwest of Hong Kong, and the average water depth in the sea area is about 80 meters. It is a high carbon dioxide oil field.

The project can capture and process carbon dioxide associated with oilfields, and re-inject it into the salt water layer at a depth of about 800 meters on the seabed for storage, achieving zero carbon dioxide emissions. The successful commissioning of the project indicates that CNOOC has a complete set of technology and equipment system for carbon dioxide capture, treatment, injection, storage and monitoring in offshore oil and gas fields, filling the gap in China's offshore carbon dioxide storage technology. After the project is put into operation, it will accumulatively store more than 1.5 million tons of carbon dioxide, which is equivalent to planting nearly 14 million trees.

Mr. Zhou Xinhuai, CEO of the company, said: "The successful commissioning of the CCS demonstration project in the Enping 15-1 oilfield will effectively promote CNOOC's increase in reserves and production as well as green and low-carbon development. The company will continue to increase research and tackle key problems, and continue to promote Green development of offshore oil and gas fields, and actively explore 'onshore carbon into the sea', to open up a new path of carbon reduction and environmental protection for coastal high-emission enterprises."
