The design and application of flow cell systems

A Vanadium Redox Battery® energy storage system has been developed with a standard energy storage module rated at 200 kW rms with a peak power of 300 kW and a normal storage time of 2 hours. However the storage time can be increased to significantly longer times, at a viable cost, by adding extra storage fluid in a larger tank. The associated power converter system is presented together with data on the need for electrical energy storage.
