On December 9, French company GTT and Hong Kong’s Liwan Group signed a letter of intent to cooperate on the construction of the world’s largest land-based membrane tank for storing multiple gases at low temperatures, with a capacity of 200,000 cubic meters, in the Daxie Development Zone in Ningbo. The total investment for the project is approximately 700 million yuan, to be funded by Ningbo Liwan New Materials Co., Ltd., a subsidiary of Liwan Group. It utilizes GTT’s proprietary GST® membrane full-volume tank technology, which enables simultaneous storage of various cryogenic substances such as LNG, liquid ammonia, and liquid hydrogen. Construction is scheduled to begin in June 2026, with completion and operation set for November 2028. Annan, General Manager of GTT in China, said that this flagship project marks another step forward in Franco-Chinese industrial cooperation, and it will provide the Chinese petrochemical industry with safer, more flexible, and more efficient storage and transportation solutions. Wang Wenxia, general manager of Liwan Group, stated that by leveraging GTT’s next-generation film technology, the group will build world-class petrochemical infrastructure to enhance the resilience of its industrial chain and its international competitiveness. Upon completion, the project will fill the gap in China for ultra-large-scale low-temperature multi-gas onshore storage tanks, drive the petrochemical industry toward higher levels of sophistication, sustainability, and intelligence, and serve as a model for Sino-French technical cooperation and a mutually beneficial energy transition.
