The process of storing thermal energy can be described in three steps, referred to as a cycle. These steps are charging, storing and discharging. The storage cycle applies to sensible, latent and chemical storage; the differences between these methods are the material, the temperature of operation and a few other parameters.
A characteristic of thermal energy storage systems is that they are diversified with respect to temperature, power level, and heat transfer fluids, and that each application is characterized by its specific operation parameters. This requires the understanding of a broad portfolio of storage designs, media, and methods.
The different technologies for heat storage and recovery There exist different types of thermal energy storage systems. These are the three main types of storage: Sensible heat storage is the most widely used. Water is often used as a carrier, since it has one of the highest volumetric heat capacities of natural existing materials.
Other sources of thermal energy for storage include heat or cold produced with heat pumps from off-peak, lower cost electric power, a practice called peak shaving; heat from combined heat and power (CHP) power plants; heat produced by renewable electrical energy that exceeds grid demand and waste heat from industrial processes.
