"Molten salt is a heat storage medium that retains thermal energy very effectively over time and operates at temperatures greater than 1000°F, which matches well with the most efficient steam turbines. Second, it remains in a liquid state throughout the plant''s operating regime, which will improve long-term reliability and reduce O&M costs.

An alternative concept for thermo-mechanical energy storage is based on heat transformation. According to Fig. 1 (left), electricity W mech is used to increase the enthalpy of Q low taken from a low temperature reservoir during the charging cycle. After transformation, the heat Q high is transferred to a reservoir/thermal storage. During …
