FAQs
Your energy storage questions, answered.
Ice-based thermal energy storage is a system that uses ice to store cooling or heating energy. During off-peak hours, a chiller produces ice, which is stored in tanks. This stored energy is then used to provide cooling or heating during peak hours, reducing the need for chiller operation when electricity rates are higher.
Ice-based thermal energy storage works by utilizing a chiller to freeze water mixed with glycol in storage tanks during off-peak hours. The ice is built uniformly around a heat exchanger inside the tank. During peak hours, the stored ice melts, cooling the glycol solution, which is then circulated to meet the building's thermal management load.
Thermal ice-based storage is worthwhile for HVAC chiller plants when there are significant peak demand charges or time-of-use rate structures, as it allows for energy consumption to be shifted to off-peak hours, reducing costs. It is also beneficial in facilities with high cooling or heating demands. Available incentives from utility companies or government programs can help further enhance ROI, making it a cost-effective solution for long-term savings.*
