Title: Thermal energy storage system with tunable phase change composition

Abstract

A thermal energy storage system includes a phase change composition including a phase change material. The phase change composition has a first melting temperature at a first hydration level and a second melting temperature at a second hydration level. The phase change composition stores thermal energy by converting from a solid to a liquid. The thermal energy storage system also includes at least one compartment containing the phase change composition and at least one tuning medium receiving water to adjust the phase change composition from the first hydration level to the second hydration level and supplying water to adjust the phase change composition from the second hydration level to the first hydration level. A method of storing and releasing thermal energy is also disclosed.
