Title: Inverse latent heat thermal energy storage system, method for capturing and releasing latent heat

Patent ·
OSTI ID:1632431

The invention provides a method for storing and releasing heat having the steps of thermally contacting thermal transfer fluid to a mixture of foam and phase change material for a time sufficient for the material to change from a first phase to a second phase during a time when electricity rates are at a first price point; maintaining said material in the second phase until electricity rates are at a second point, wherein the second point is higher than the first price point; and thermally contacting the thermal transfer fluid to the composite in the second phase for a time sufficient for the material to change from the second phase to the first phase. The invention also provides an energy storage module having a mixture of phase change material and high surface area substrate
