Olszewski, M

An advanced thermal energy storage media concept is being developed for industrial process and reject heat applications. This composite medium consists of a phase-change carbonate salt, supported and immobilized within a submicron-sized capillary structure of a particulate ceramic matrix of porous sintered ceramic. Immobilization of the molten salt within the ceramic structure permits operation of the composite pellets, bricks or other shapes in direct contact with compatible fluids. Energy storage occurs in both sensible and latent forms with the composite providing higher energy storage densities than standard sensible heat storage systems. This paper describes the composite latent/sensible media concept and its potential advantage over state-ofthe-art systems. Current development activities concerning media stability and fabrication are described. Economic viability of the concept, especially in comparison to extant sensible heat storage systems, is also presented.
