Phase Change Materials (PCMs) can store and release large amounts of energy as they change phase between solid and liquid. PCMs provide thermal energy storage and can be used to prolong temperatures for cooling and heating applications without an external energy source. PLUSS is an Indian company that develops and provides various PCM technologies and solutions. Their PCM products include hydrated salt based and organic PCMs that can be tailored for different temperature ranges and used in applications like cold transportation, building energy efficiency, and human thermal comfort.
