Energy Storage Density
Take paraffin (n -docosane) with a melting temperature of 42–44°C as an example: it has a latent heat of 194.6 kJ/kg and a density of 785 kg/m 3 [6]. The energy density is 42.4 kWh/m 3. Nonparaffin organic PCMs include the fatty acids and glycols. Inorganic PCMs include salt hydrates, salts, metals, and alloys.

Gravimetric energy density
55 MJ/kg. Gravimetric energy density, sometimes referred to as specific energy, is the available energy per unit mass of a substance. Gravimetric energy density is typically expressed in Watt-hours per kilogram (Wh/kg), or Megajoules per kilogram (MJ/kg). [1] The gravimetric energy density gives the energy content of a fuel in terms of storage ...
