ABSTRACT:
An advanced, thermal energy storage (TES) subsystem is being developed by the Institute of Gas Technology (IGT) which employs composite phase change material (PCM)/sensible heat media (CompPhase•). This medium/ subsystem is amenable to high temperature thermal storage applications such

as industrial reject/process heat recovery and utilization, off-peak utility, and solar thermal and solar dynamic space 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 TES system performance and cost advantages are thereby offered over conventional tube intensive indirect contact moltensalt latent-heat-based storage subsystems. Materials processing, stability analysis, modeling and development efforts are progressing on composite systems from 390° to 1750°F. Performance testing of a bench-scale packed-bed unit with ~50 lbs of pellets has accumulated over 6000 hours and 200 thermal cycles, with excellent media stability (~.3% weight loss in 1000 hours) and high heat transfer rates (~10,390 Btu/hr discharge heat-removal rate.
