Phase change materials (PCM) are substances that absorb and release thermal energy during the process of melting and freezing. When a PCM freezes, it releases a large amount of energy in the form of latent heat at a relatively constant temperature.

The most commonly used PCM is water/ice. Working closely with the University of South Australia, Glaciem is on the cutting edge of PCM research and development. Advances in the composition of these materials are allowing Glaciem’s Thermcold ice battery technology to deliver reliable cooling at temperatures far outside the typical thermodynamic limits of water/ice.
