CO2 capture, storage facility makes tech advance
A carbon dioxide (CO2) capture and liquefaction facility now runs smoothly in south China's Hainan Free Trade Port (FTP), signaling a major technological advance in the region's push toward green and low-carbon development.
The facility, located in Hainan's Chengmai County, was developed by Southern Petroleum Exploration and Development Corporation -- a Hainan-based subsidiary of China National Petroleum Corporation (CNPC) -- which focuses on oil and gas exploration and new energy development.
It captures, purifies and liquefies CO2 extracted from associated oilfield gas, with daily output of liquid CO2 now surpassing 100 metric tonnes.
"To date, our pilot project has cumulatively stored 360,000 tonnes of CO2 while boosting oil and gas output by 150,000 tonnes. This is equivalent to offsetting the annual carbon emissions of about 150,000 cars," said Wang Haisheng, executive director of Southern Petroleum Exploration and Development Corporation.
Building on its successful industrialization of carbon capture, utilization and storage (CCUS), the corporation is now pioneering advanced carbon storage technologies.
By refining capture technology and implementing a multi-dimensional monitoring network, the project has achieved long-term and stable CO2 storage, solidifying the foundation for a safe and low-carbon energy system in Hainan.
