A new way to store thermal energy

A common approach to thermal storage is to use what is known as a phase change material (PCM), where input heat melts the material and its phase change — from solid to liquid — stores energy. When the PCM is cooled back down below its melting point, it turns back into a solid, at which point the stored energy is released as heat.

General Information. Flywheels store energy by accelerating a rotor to a high speed and maintaining it as rotational kinetic energy. To maintain the energy in the system, any resistance is minimized by using magnetic bearing systems and by keeping the rotor system inside a vacuum chamber to reduce frictional losses and minimize heat transfer in and out of the unit.
