Refrigeration Thermal Energy Storage Pilot

With funding from the Minnesota Department of Commerce, Slipstream is seeking pilot sites to test the potential for refrigeration thermal energy storage (RTES) systems to save energy, limit demand, and reduce carbon emissions on the grid.

RTES systems include traditional ice storage and new technologies using phase change materials and controls-based thermal flywheeling. These systems shift energy usage to time periods with lower prices and implement demand management. Built-in analytics help lower operating and maintenance costs and improve temperature management.

New refrigeration thermal energy storage technologies can save energy, reduce bills, and lower operation and maintenance costs. Grocery stores, cold storage facilities, or other existing buildings with large refrigeration systems are encouraged to apply.
