China commissioned its first offshore carbon capture, utilization and storage (CCUS) facility at the Enping 15-1 oilfield in the Pearl River Mouth Basin on Thursday, marking a major technological advancement in maritime carbon management, China National Offshore Oil Corporation (CNOOC) announced Thursday.
Located in 90-meter-deep waters about 200 kilometers southwest of Shenzhen City, south China's Guangdong Province, the project employs a full-chain process to capture, purify, compress and inject associated carbon dioxide (CO2) from oilfield operations.
The system converts CO2 into supercritical state and injects it into reservoirs 1,200 to 1,600 meters below the seabed at a rate of eight tonnes per hour, simultaneously enhancing crude oil recovery while permanently sequestering greenhouse gases.
"The successful commissioning of this project marks a comprehensive upgrade in China's offshore CCUS equipment technology. Over the next decade, it will enable large-scale reinjection of over one million tonnes of carbon dioxide while boosting crude oil production by 200,000 tonnes," said Xiong Shuquan, chief engineer of Enping Oilfield Operations of the CNOOC Shenzhen Branch.
The Enping 15-1 platform, Asia's largest offshore oil production facility, has been retrofitted with domestically-developed CO2 compressors and gas processing systems to create China's first integrated offshore CCUS engineering system with 100-percent China-made equipment.
China's offshore areas possess an estimated 2.58 trillion tonnes of CO2 storage capacity, providing vast potential for scaling the technology. CNOOC has already initiated a 10-million-ton carbon capture and storage cluster project in Huizhou City of Guangdong, aiming to create an internationally competitive offshore CCUS industrial chain by transporting emissions from Daya Bay industries to underwater storage sites in the Pearl River Mouth Basin.
Marine environments are emerging as prime carbon storage locations globally due to their distance from populated areas and enormous capacity. China's rapid CCUS technological developments are transitioning pilot projects into large-scale applications, positioning the country at the forefront of this critical climate solution sector.
