China National Offshore Oil Corporation (CNOOC) has officially teamed up with Shell, ExxonMobil and southern China’s Guangdong province to apply carbon capture, utilisation and storage (CCUS) technology to help reduce carbon emissions from petrochemical complexes in Guangdong, the country’s economic powerhouse.

The signing of the agreement earlier this year formalises the memorandum of understanding the parties reached in June, when they initially agreed to evaluate the potential for world-scale CCUS projects at the Daya Bay National Economic & Technological Development Zone.
