Frequently Asked Questions
Your Thermal Battery Energy Storage System questions, answered.
A thermal battery stores energy in the form of water or ice for later use.
Thermal energy storage systems can store heat in a very wide range of temperatures for later use. Depending on the temperature, the energy during discharge can be in the form of electricity, cooling or heat.
Thermal battery storage systems, a type of thermal energy storage, use modular, compact devices to manage thermal energy for cooling or heating more effectively. For heating, thermal battery storage reclaims and stores excess heat from a building’s HVAC system, and depending on the season, reuse the heat in the winter to heat the building or reject the heat during the summer during off-peak hours to reduce energy costs.
A thermal battery plant is a chiller plant or hydronic heat pump chiller plant enhanced with thermal energy storage.
