On November 2nd, the ShouHang’s 300,000 kilowatts thermal storage + electrochemical energy storage project, with a total investment of 2.395 billion yuan, commenced construction in the Changji National High-tech Industrial Development Zone, Xinjiang Uygur Autonomous Region, marking the official start of the engineering construction phase.
The project plans to build an independent energy storage power station with molten salt thermal storage (cold, heat, electricity, and steam quadruple supply) in a one-time planning and construction. The construction scale is 200MW/800MWh of molten salt energy storage + 100MW/400MWh of electrochemical (lithium iron phosphate) energy storage. Among them, the chemical energy storage + thermochemical thermal storage heating project is expected to be fully operational by the end of 2026, and the molten salt thermal storage project is scheduled to be grid-connected by mid-2027.
Huang Wenbo, Chairman of ShouHang High-tech Energy Technology Co., Ltd., the executive vice-chairman unit of China Solar Thermal Alliance, stated that the new energy storage technology of "high-temperature molten salt + compressed carbon dioxide" achieves a quadruple supply of cold, heat, electricity, and steam, with an energy utilization rate of 85%, low cost, long life, and no geographical restrictions, making it the preferred technology for power optimization and multi-energy complementarity.
The project can fully utilize the surplus electricity during the grid's low-valley period to compress carbon dioxide and return to the grid during peak times, effectively "trimming peaks and filling valleys," undertaking multiple key grid tasks. After completion, the project will effectively alleviate the local grid's peak-shaving demand, work with other peak-shaving power sources to ensure grid stability, meet the peak-shaving demands of the Changji High-tech Zone, and solve the problem of uneven load around the grid.
