Discharge mode is shown; the arrows are reversed for electrolytic/charge mode. In contrast, flow batteries can independently scale the power (electrode area) and energy (arbitrarily large storage volume) components of the system by maintaining all of the electro-active species in fluid form. Cell schematic. Huskinson et al. Background.

Classification of potential electrical storage for stationary applications. To be successful, systems will need to evolve—in some cases, considerably—to compete financially with the cost of natural gas production. Approximation of capital cost per cycle of different ESS technologies. Credit: ACS, Yang et al.

Currently, metal-supported fuel cells use high-temperature electrolytes; using an intermediate temperature electrolyte will allow an operating temperature of 500°C while a redesigned cell architecture will increase the efficiency and lower the cost of UTRC’s overall system.
