OSTI ID:5591892
An advanced, thermal energy storage (TES) sub-system is being developed by the Institute of Gas Technology (IGT) under the sponsorship of the Department of Energy (DOE) through Oak Ridge National Laboratory (ORNL). This subsystem employs a family of composite phase change material (PCM)/sensible heat media (CompPhase). The basis- and engineering-research efforts have focused on the development of these media for low (400/sup 0/F) and high (900/sup 0/ to 2500/sup 0/F) temperature regimes. As such, the media subsystem is amenable to high temperature storage applications such as industrial reject/process heat recovery and utilization, off-peak utility, solar thermal, solar chemical and fuels, and space solar dynamic power systems. The CompPhase concept allows for direct contact heat exchange between the latent/sensible storage media and compatible working fluids. A number of potentially significant performance and cost advantages are thereby offered over conventional tube-intensive indirect contact molten salt laten-heat-based storage systems.
