The main disadvantages are: Low charge and discharge rates. Lower energy efficiency, because they operate at higher current densities to minimize the effects of cross-over (internal self-discharge) and to.

The project, at Bushveld's Vametco Alloy mine, will pair 3. 5MW of solar PV with a 1MW/4MWh vanadium redox flow battery (VRFB) system. 7% of the mine's energy needs as well as serving as a demonstration and trial of the technology's suitability for mining.
