There are several means to store energy and Phase Change Materials (PCMs) are one of the most effective and efficient materials to store thermal energy from conventional and renewable energy sources. PCMs are materials that have an intrinsic ability to absorb and release heat during phase transition cycles.

Phase change materials (PCMs) are ideal for use in any application where a storage and release of thermal energy is desired. PCMs act like a battery for heat energy because they absorb heat energy as they melt and can be “recharged” by cooling them until they crystallise and give the stored energy back the environment.
