The transformation and adjustment of China’s energy structure has opened new opportunities for energy storage technology. For instance, it promises to improve the quality of renewable power generation,reduce the power limitation rate of wind farms and photovoltaic power stations, and enhance multiple aspects of power systems. Energy storage plays an important role in todays emerging third industrial revolution, which will continue into the future energy internet. A central enterprise dedicated to renewable energy development, called the State Power Investment Corporation Research Institute(SPICRI), has developed iron-chromium redox flow batteries for electrical energy storage. These batteries have several advantages such as high roundtrip efficiency, long service life, wide temperaturerange operability, modular power design, customized capacity design, high safety, environmental friendliness, and low cost. Therefore, they are suitable for various renewable energy sources such as wind, solar, smart grids, and microgrids. Moreover, the manufacturing technology is expected to upscale to large-scale energy storage. As an engineering case study, this paper introduces the 250 kW/1.5 MW·h ironchromium redox flow batteries developed for an energy-storage demonstration power station, which is under construction by SPICRI. The SPICRI station is Chinas first power station with a hundred-kilowatt-level storage capacity. The rated output power and capacity of the energy storage demonstration power station are 250 kW and 1.5 MW·h, respectively. When operated commercially on large scales, the iron-chromium redox flow battery technology promises new innovations in energy storage technology.
