The energy storage phase change material (PCM) has possesses a larger energy storage capacity with faster thermal response than existing materials and could be cheaply manufactured.
If the desired temperature in a room is 22°C, the material can be adjusted so that it starts absorbing any excess heat above that temperature.
The material is the size of a large coin and can be manufactured in a variety of shapes and sizes. It also can be used in both existing and new buildings.
