6 FAQs about [There are problems with phase change material energy storage]

Are phase change materials suitable for thermal energy storage?

Phase change materials (PCMs) having a large latent heat during solid-liquid phase transition are promising for thermal energy storage applications. However, the relatively low thermal conductivity of the majority of promising PCMs (<10 W/ (m ⋅ K)) limits the power density and overall storage efficiency.

What are the different methods of storing energy?

Different methods of storing energy are available including: electrical, mechanical, chemical, and thermal energy storage (TES). Thermal heat energy storage is associated with the solar thermal energy. It is divided for non-reactive materials into sensible energy storage (SHS) and latent heat energy storage (LHS) as illustrated in Fig. 1. Fig. 1.

Are inorganic PCMs a good choice for a latent heat storage system?

One of the challenges for latent heat storage systems is the proper selection of the phase change materials (PCMs) for the targeted applications. As compared to organic PCMs, inorganic PCMs have some drawbacks, such as corrosion potential and phase separation; however, there are available techniques to overcome or minimize these drawbacks.

What happens when a solid storage material is exposed to heat?

When the solid storage material is exposed to heat, the temperature starts to rise according to the amount of energy absorbed until the material temperature reaches the phase transformation (melting) temperature, which in turn the storage material will start to melt and transform from the solid phase to the liquid phase.

How does a PCM control the temperature of phase transition?

By controlling the temperature of phase transition, thermal energy can be stored in or released from the PCM efficiently. Figure 1 B is a schematic of a PCM storing heat from a heat source and transferring heat to a heat sink.

Which issues have restricted the use of latent heat storage?

The issues that have restricted the use of latent heat storage include the thermal stability of the storage materials and the limitation of the container size. The study of the influence of thermal cycling on the properties of PCMs, such as melting temperature and latent heat, is important.
