Figure 1 illustrates the flow battery concept. Figure 1: Flow Battery. Electrolyte is stored in tanks and pumped through the core to generate electricity; charging is the process in reverse. The volume of electrolyte governs battery capacity. Vanadium is the 23 rd element on the periodic table and is mined in China, Russia and South Africa.

An attribute of flow batteries is the ability to independently size the power stack and chemical storage capacity to meet desired energy to power ratios. In such architecture, the contribution to system cost of the power stack can be minimized by sizing it only as large as is necessary to meet the maximum power requirement.
