About China Storage Guoneng (Beijing) Technolog

China Storage Guoneng (Beijing) Technology Co., Ltd. (ZCGN) is a trailblazer in the advanced compressed air energy storage (A-CAES) sector, established in December 2018. The company's core technology originates from the Institute of Engineering Thermophysics (IET) of the Chinese Academy of Sciences (CAS), positioning ZCGN as the institute's industrialization platform for this technology.

The company's scientific founder is Chen Haisheng, a researcher at the IET and the originator of China's A-CAES technology. His research began in 2004, leading a team that progressively developed systems from kilowatt-scale to megawatt-scale, achieving significant milestones such as the 1.5MW system in 2013, 10MW in 2016, 100MW in 2021, and a 300MW system in 2024. The company is led by General Manager Ji Lv.

ZCGN provides comprehensive solutions for A-CAES systems, including research and development, design, core equipment manufacturing, system integration, and power station investment and operation. The business model focuses on developing large-scale energy storage projects that serve the power grid. These stations store electricity during off-peak hours by compressing air and then release it to generate power during peak demand. Revenue is expected to be generated through participation in China's electricity trading market by offering services like peak shaving, frequency regulation, and standby power. The company's A-CAES technology does not rely on fossil fuels, making it an environmentally friendly solution for grid-scale energy storage.

The company's key product is its advanced compressed air energy storage system, which can be scaled from 1MW to over 300MW. A significant feature is its high efficiency, with 100MW and 300MW systems achieving efficiencies of over 70%. The system stores compressed air in various geological formations, such as salt caverns or artificially constructed chambers, making it flexible in terms of location. ZCGN has successfully developed and built several national demonstration projects, including the world's first 100MW A-CAES plant in Zhangjiakou and the world's largest 300MW/1800MWh facility in Feicheng, Shandong province. The company has achieved 100% independent intellectual property rights for its core technologies, including multi-stage compressors and high-load turbine expanders.
