Abstract
Systems and methods providing modular and scalable flow batteries are disclosed. The modular design can utilize the ability of flow batteries to separate power, provided by a battery stack, from energy, provided by a stored electrolyte. Power of the system can be determined by a number of battery cell stacks, while stored energy capacity of the system can be determined by how much electrolyte is available for use by the battery cell stacks. Catholyte and anolyte solutions can be stored in pipes having an adjustable length. Electrolyte storage capacity can be increased by increasing the length of the pipes by an amount sufficient to provide a desired increase in electrolyte storage. Alternatively, electrolyte storage capacity can be decreased by decreasing the length of the pipes.
