ENERGY STORAGE AND THERMAL MANAGEMENT USING PHASE CHANGE MATERIALS IN CONJUNCTION WITH HEAT PIPES AND FOILS, FOAMS OR OTHER POROUS MEDIA

In one aspect an apparatus to store energy comprises a housing defining an enclosed chamber, foils or foam formed from a thermally conductive material disposed in the chamber, a phase change material disposed within the chamber, and at least one heat pipe extending through the housing in thermal communication with the foam, or foil, and the phase change material. Other aspects may be described.
