中国海洋石油集团(CNOOC)于6月1日称，我国首个百万吨级海上二氧化碳封存(CCS)工程项目在南海正式投入使用。该项目总计可封存超150万吨的二氧化碳，相当于植树近1400万棵。这一CCS项目服务于距离深圳西南约200公里的恩平15-1原油钻采平台，能够将油田开发伴生的二氧化碳捕获并处理，回注至距平台3公里远、在海床约800米底下的“穹顶”式地质构造中。该项目的运行标志着我国成功掌握了海上二氧化碳捕集、处理、注入、封存和监测的全套技术和装备体系。

China's first offshore million-tonne carbon storage project was put into operation on Thursday in the South China Sea, according to the China National Offshore Oil Corporation (CNOOC). The project is designed to store a total of more than 1.5 million tonnes of carbon dioxide (CO2), which is equivalent to planting nearly 14 million trees. The project, serving the Enping 15-1 oil platform 200 km southwest of Shenzhen, captures and processes CO2 from oilfields and then injects CO2 into a "dome" geological structure at a depth of around 800 meters under the seabed and about 3 km from the platform. The operation of the project signifies China's achievement in acquiring a complete set of technologies and equipment for capturing, processing, injecting, storing and monitoring CO2 at sea.
