China National Offshore Oil Corp. (CNOOC) Guangdong Dapeng LNG terminal has launched China's first demonstration project of liquefied natural gas (LNG) cold energy aquaculture for aquatic cultivation.
The Shenzhen Government has published on its website that during LNG vaporization and distribution, a huge amount of cold energy is produced, and discharging it directly would result in significant energy waste. In 2023, the Dapeng station’s cold energy processing exceeded 8 million tons.
Consequently, CNOOC decided to utilize the cold energy resources generated from the process by constructing a modern cold energy aquaculture area within the station, integrating green energy with aquaculture. "It marks a new step in the construction of modern "ocean ranches" in the domestic LNG industry."
The facility is similar to a marine aquarium, where lobsters, groupers, and other fish swim in the cold water, while technical personnel monitor and record the water temperature and quality in the aquaculture ponds.
The terminal is one of the largest LNG receiving stations in China and it is expected to produce an estimated annual output of up to 50,000 kilograms.
Cao Yueming, secretary-general of the Seed Branch of the Shenzhen Fisheries Industry Association, said: "The economic benefits of the trial project are considerable. The market price of the high-value marine products being cultivated is over 100 yuan per 500 grams, and the cost can be reduced by 30% compared with traditional aquaculture."
