A Review on Phase Change Materials : Matehematical Modelling and Simulations (1/3)

The ever increasing level of greenhouse gas emissions combined with the overall climbed in fuel prices (although fluctuations occur) are the main reasons behind efforts devoted to improve the use of various sources of energy.  Economists, scientists, and engineers throughout the world are in search of: 1) strategies to reduce the demand; 2) methods to ensure the security of the supplies; 3) technologies to increase the energy efficiency of power systems; and 4) new and renewable sources of energy to replace the limited and harmful fossil fuels.
One of the options to improve energy efficiency is to develop energy storage devices and systems in order to reduce the mismatch between supply and demand.  Such devices and systems also improve the performance and reliability of their traditional counterparts and thus play a preponderant role in conserving the energy.  The different forms of energy that can be stored are mechanical, electrical, and thermal.  Here, mechanical (gravitational, compressed air, flywheels) and electrical (batteries) storages are not considered while thermal energy storage is discussed in the context of latent heat (sensible heat and thermochemical heat are not considered).
Latent heat storage is based on the absorption/desorption of energy when a storage material undergoes a phase change from solid to liquid, liquid to gas, or vice versa.  Latent heat storage is particularly attractive since it provides a high-energy storage density and has the capacity to store energy at a constant temperature – or over a limited range of temperature variation – which is the temperature that corresponds to the phase transition temperature of the material.  For instance, it takes 80 times as much energy to melt a given mass of water (ice) that to raise the same amount of water by 1°C.
