Abstract
A thermal energy storage system includes a heat exchange module having a quantity of phase change material and a quantity of reference gas in fluid communication with the phase change material. A sensor is provided for sensing the reference gas pressure and generating a pressure signal that is related to the reference gas pressure. The exchange of heat changes the heat of the phase change material, a change in the phase of the phase change material, and a change in the total volume of the phase change material. This changes the volume of the reference gas, and also changes the reference gas pressure. The sensor will detect and generate a signal of the reference gas pressure change and form this a change in the state of charge of the phase change material can be determined. A thermal energy storage system and method for storing thermal energy are also disclosed.
