Breakthrough of 100 Million Cubic Meters! Major Progress Achieved in China’s First Offshore Carbon Storage Project

　　Xinhua Finance, Beijing, September 10 (Anna, Guo Zhouyang) — According to CNOOC, as of September 10, the cumulative carbon dioxide storage of the Enping 15-1 oilfield carbon storage project, China’s first offshore CO₂ storage demonstration project located in the Pearl River Mouth Basin, has exceeded 100 million cubic meters. This reduction in carbon emissions is equivalent to planting 2.2 million trees, marking the maturation of China’s offshore carbon dioxide storage technology, equipment, and engineering capabilities. It is of great significance for accelerating the achievement of the national "dual carbon" goals and promoting the green, low-carbon transformation of the economy and society.

　　After four years of research, CNOOC took the lead in launching China’s first offshore CCS (Carbon Capture and Storage) project at this oilfield, with an annual CO₂ storage capacity of over 100,000 tons. In May this year, China’s first offshore CCUS (Carbon Capture, Utilization, and Storage) project was put into operation at the oilfield platform, achieving a full-chain upgrade of offshore CCUS equipment, technology, and engineering. Through technological means, it not only drives crude oil production increase but also achieves CO₂ storage, creating a new model of marine energy recycling—"using carbon to drive oil production and using oil to sequester carbon." Over the next 10 years, the oilfield will inject over 1 million tons of CO₂, driving a crude oil production increase of 200,000 tons.

　　CNOOC is actively leading the trend of offshore CCUS development, promoting its transition from single-point demonstration to clustered development. The company has launched China’s first 10-million-ton carbon capture and storage cluster project in Huizhou, Guangdong, which will precisely capture CO₂ emissions from enterprises in the Daya Bay area and transport them to the Pearl River Mouth Basin for storage, forming a complete and internationally competitive offshore CCUS industry chain. Meanwhile, CNOOC is fully leveraging the vast potential of CO₂ in enhancing oil and gas recovery rates, planning to establish a northern CO₂-driven oil recovery center centered on the Bozhong 19-6 gas field and build a southern CO₂-driven gas recovery center based on the trillion-cubic-meter gas region in the South China Sea.

　　Wu Yiming, Production Department Manager of CNOOC Shenzhen Branch, stated that the steady development of CCUS technology will provide technical support for achieving China’s "dual carbon" goals, promote the transformation and upgrading of the energy industry toward green, low-carbon, and sustainable development, and contribute Chinese solutions and strength to global climate governance.
