English: A Vanadium Redox flow battery located at the University of New South Wales (UNSW Australia), in Randwick, NSW. This particular one is located at the Randwick campus, rather than the main campus. Practical Vanadium Redox batteries were invented at UNSW by Professor Maria Skyllas-Kazacos. This particular battery is a part of an integrated grid-tie system in conjunction with a solar array and wind turbine, but it is currently out of use. Not shown are the electrolyte tanks and pumps, which are below the cell stack.
