Thermal energy tanks are reservoirs for storing energy in chilled water district cooling systems. Water has a better thermal transfer than air. . A game-changing technology developed by NREL in collaboration with Blue Frontier Inc. offers a solution to lower a building's electricity bills and help reduce demand on the grid: the Energy Storing and Efficient Air Conditioner (ESEAC). Designed for commercial use, ESEAC integrates energy storage. . Thermal Energy Storage (TES) for space cooling, also known as cool storage, chill storage, or cool thermal storage, is a cost saving technique for allowing energy-intensive, electrically driven cooling equipment to be predominantly operated during off-peak hours when electricity rates are lower. . Whether you are facing sustainability, resiliency or certain operational and financial challenges, Trane® thermal energy storage can be part of the solution. A flexible way to manage electric demand.
