Abstract. The use of thermal energy storage (TES) allows to cleverly exploit clean energy resources, decrease the energy consumption, and increase the efficiency of energy systems. In the past twenty years, TES has continuously attracted researchers generating an extensive scientific production growing year by year.
A large amount of energy is consumed by heating and cooling systems to provide comfort conditions for commercial building occupants, which generally contribute to peak electricity demands.

A promising technology for performing that task is the flow battery, an electrochemical device that can store hundreds of megawatt-hours of energy — enough to keep thousands of homes running for many hours on a single charge. Flow batteries have the potential for long lifetimes and low costs in part due to their unusual design.
