Chinese state-owned oil and gas firm CNOOC has completed the country's first offshore carbon capture and storage project designed to permanently bury carbon dioxide in the seabed, state media reported recently. The project is located at the company's Enping oil field in the mouth of the Pearl River, about 200 km (124 miles) from Shenzhen, and will store CO2 emitted during the oil extraction process, state broadcaster CCTV reported. CNOOC began constructing the project last September and said it would eventually sequester a total of 1.46 million tonnes of CO2 in 800-meter deep seabed reservoirs. The stored carbon dioxide was the equivalent of planting 14 million trees or taking 1 million cars off the road, the company said.
