Thermal storage systems remove heat from or add heat to a storagemedium for use at another time. Thermal energy storage (TES) for HVAC and/ordomestic water-heating applications can involve various temperatures associatedwith heating or cooling. High-temperature storage is typically associated withsolar energy or high-temperature heating, and cool storage withair-conditioning, refrigeration, or cryogenic-temperature processes. Energy maybe charged, stored, and discharged daily, weekly, annually, or in seasonal orrapid batch process cycles. Fast-acting and/or grid-interactive energy storagesystems can provide balancing services and other critical needs of the electricgrid, such as frequency control and renewable energy integration. Thesegrid-interactive systems dynamically couple consumer energy usage to the grid’sreal-time needs. Historically, thermal storage has been used for comfort andprocess heating and cooling applications as a way to reduce the total utility billand/or size of heating and cooling equipment. Dorgan and Elleson (1993) covercool storage issues and design parameters in detail.
