Classification: CPC C  F  Y | IPC C  F

Claim 5:
6. A thermal energy storing system comprising:
a first tank containing a volume of a formulation of active material including a solvent and one or more of a salt, a base, or an acid as the active material, the formulation having multiple congruent solid phase transition temperatures at different concentrations of the solvent, wherein the formulation at each congruent solid phase transition temperature has the same solvent concentration when in the liquid phase and solid phase;
a temperature controller configured to control a temperature of the formulation within the first tank; and
a concentration controller configured to adjust the concentration of the solvent in the formulation,
wherein the solid phase transition temperature of the volume of the formulation of active material is adjustable by changing the concentration of solvent in the formulation from a first concentration with a first congruent solid phase transition temperature to a second concentration with a second congruent solid phase transition temperature and the system is configured to change a concentration of solvent in the volume of the formulation of active material by evaporation and condensation of the solvent within the at least one of the two or more volumes of the formulation.
