Iphrojekthi yokuqala ye-carbon storage emanzini eChina ifinyelele intuthuko enkulu, idlula izigidi eziyi-100 zamamitha kubhavu

On September 10, China National Offshore Oil Corporation (CNOOC) announced that the cumulative carbon dioxide storage volume 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 achievement is equivalent to reducing carbon emissions by planting 2.2 million trees, marking the maturity of China’s offshore carbon dioxide storage technology, equipment, and engineering capabilities. It holds significant importance for accelerating the realization of the country’s "dual carbon" goals and promoting green, low-carbon economic and social transformation.

Njengoba i-oyili yokuqala enokhiye ophakeme we-carbon dioxide eMpumalanga yeNingizimu China Sea, i-Enping 15-1 oilfield, uma ithuthukiswa ngemicimbi ejwayelekile, izokhiqiza i-carbon dioxide kanye ne-oyili elikhulu. Lokhu kuzokwenza kungabi nje kuphela ukugqoka izinsiza zephakheji ezisemanzini kanye neziteshi ze-subsea kodwa futhi kuzokwandisa ukukhishwa kwe-carbon dioxide, okuphikisana nemigomo yokuthuthukiswa okuluhlaza.

Ngemuva kweminyaka emine yocwaningo, i-CNOOC iholele ekwakhiweni kwephrojekthi yokuqala ye-CCS (Ukutholwa Nokugcina kweKhabhoni) ehlathini le-oyili, enekhono lokugcina i-CO₂ elingaphezu kwamathani angama-100,000 ngonyaka. NgoMeyi walo nyaka, iphrojekthi yokuqala ye-CCUS (Ukutholwa, Ukusetshenziswa Nokugcina kweKhabhoni) yaseChina yaqalelwa epulatifini yalesi sikhungo se-oyili, yafeza ukuthuthukiswa okuphelele kwezinsiza, ubuchwepheshe, kanye nezinhlelo zokusebenza ze-CCUS yasolwandle. Ngokusebenzisa izindlela zobuchwepheshe ukuze kuthuthukiswe ukukhiqizwa kwe-oyili eluhlaza nokugcina i-CO₂, le phrojekthi isungule imodeli entsha yokuphinda isetshenziswe kwamandla olwandle ebonakaliswa ngokuthi "ukusebenzisa i-CO₂ ukuze kuqhutshwe ukukhiqizwa kwe-oyili nokubamba ikhabhoni ngokukhiqizwa kwe-oyili." Phakathi kweminyaka eyishumi ezayo, kulindeleke ukuthi lesi sikhungo se-oyili singenise ngaphezu kwamathani ayizigidi eziyi-1 ze-CO₂, sikhuphule ukukhiqizwa kwe-oyili eluhlaza ngaphezu kwamathani angama-200,000.

Xu Xiaohu, Deputy General Manager of the Enping Operations Company under CNOOC Shenzhen Branch, stated: "Since its official commissioning, the project has been operating safely for over 15,000 hours, with a peak daily CO₂ injection capacity of 210,000 cubic meters. By adopting an innovative model that integrates ecological protection with energy development, it provides a replicable and scalable new pathway for the green and low-carbon exploitation of China’s offshore oil and gas fields. This initiative stands as a major practical achievement in China’s efforts to realize its carbon peak and carbon neutrality goals."

CNOOC is actively leading the trend in offshore CCUS development, driving its evolution from standalone demonstration projects toward clustered expansion. The company has launched China’s first ten-million-ton carbon capture and storage cluster project in Huizhou, Guangdong, which will precisely capture carbon dioxide emissions from enterprises in the Daya Bay area and transport them for storage in the Pearl River Mouth Basin. This initiative aims to establish a complete and internationally competitive offshore CCUS industry chain.

Ngokunjalo, i-CNOOC isebenzisa ngokuphelele amandla amakhulu e-carbon dioxide ekwandiseni ukutholwa kwe-oyili negesi. Izinhlelo zikhona zokwakha isikhungo sokutholwa kwe-oyili esithuthukiswe nge-CO₂ eningizimu yeBozhong 19-6 gas field, kanye nehub yokutholwa kwegesi esithuthukiswe nge-CO₂ esebenzisa isifunda sezigidi eziyizigidi eziyizinkulungwane ze-gesi yemvelo eNingizimu yeSizinda saseChina.

Wu Yiming, Umphakathi weMveliso eCNOOC Shenzhen Branch, uthe: "Ukuthuthuka okuqinile kwe-CCUS technology kuzohlinzeka ngensiza yezobuchwepheshe ukuze iChina ifinyelele imigomo yayo ye-'dual carbon', iqhube ukuguqulwa komkhakha wamandla kube ngowokuhlanzeka, ophansi kwekhabhoni, nokuthuthukiswa okungaguquki, futhi ibe negalelo ezixazululweni nasekuqiniseni kweChina ekuphathweni kwesimo sezulu emhlabeni."
