The gas island project of Zhongshan Triangle Town is located in Gaoping Park, Triangle Town, Zhongshan City, Guangdong Province. The project is divided into two phases, the first phase mainly includes 500,000 cubic meters/year helium separation and special gas device, 400TPD liquid air separation device and 2000Nm³/h hydrogen production device. The total investment of the project is 400 million yuan, covering an area of 63 mu. The project started construction in June 2022 and is expected to begin production in 2023. The project is the first integrated gas island project in the Guangdong-Hong Kong-Macao Greater Bay Area covering helium, hydrogen energy, electronic special gas and air separation units. Upon completion, it will become the first domestic helium supply base in the Greater Bay Area. At the same time, as the first industrial gas source in Zhongshan City, the project can supply the industrial gas demand of the entire city, and become the first hydrogen energy supply base in Zhongshan City, which can solve the problem of hydrogen shortage in Zhongshan City, and radiate to serve the hydrogen energy supply demand in the surrounding areas.
