Abstract
An energy storage system comprises a hot thermal energy storage medium and a cold thermal energy storage medium, which are interconnected in a thermodynamic gas flow circuit with gas as a working fluid. An energy converter with a motor/generator system is functionally connected to a compressor/expander system for converting between electrical energy and thermal energy of the gaseous working fluid in the thermodynamic fluid circuit. A latent TES medium is thermally connected to the thermodynamic circuit for providing a lower limit for the temperature in the cold TES medium. Specifically, the latent TES medium is liquid, typically water, which is sprayed as droplets into a tank through which the gaseous working fluid flows at subzero temperatures to produce snow in order to efficiently heat the gas to the freezing point or above.
