Energy storage systems, namely, thermal matrix energy storage systems, thermal energy storage systems, thermal energy storage systems for storing electric energy provided during low-priced, non-peak periods or from excess wind or solar energy, for use during high priced or high-demand periods to drive either thermal systems or a turbine, and graphite-based storage systems using an inert gas mixture within a protective container that efficiently stores thermal energy for extended periods at low loss rates, namely, heat accumulators
