Abstract
Energy storage systems and methods use medium voltage (MV) electrical heat exchangers to increase the efficiency of the energy storage system and/or reduce emission of pollutants. MV electrical heat exchangers use medium range voltages to heat a fluid, such as a gas or liquid. The heated fluid is used in the energy storage system to either drive a turbine generator directly or indirectly, such as by generating steam to drive the turbine generator. The electricity used to power the MV electrical heat exchangers can be from renewable energy sources, such as solar or wind-powered sources, further increasing efficiency of the energy storage system.
