Thermal storage systems remove heat from or add heat to a storage medium for use at another time. Thermal energy storage (TES) for HVAC and/or domestic water-heating applications can involve various temperatures associated with heating or cooling. High-temperature storage is typically associated with solar energy or high-temperature heating, and cool storage with air-conditioning, refrigeration, or cryogenic-temperature processes. Energy may be charged, stored, and discharged daily, weekly, annually, or in seasonal or rapid batch process cycles. Fast-acting and/or grid-interactive energy storage systems can provide balancing services and other critical needs of the electric grid, such as frequency control and renewable energy integration. These grid-interactive systems dynamically couple consumer energy usage to the grid’s real-time needs. Historically, thermal storage has been used for comfort and process heating and cooling applications as a way to reduce the total utility bill and/or size of heating and cooling equipment. Dorgan and Elleson (1993) cover cool storage issues and design parameters in detail.
