6 Frequently Asked Questions about “Liquid phase change energy storage materials”
Are solid–liquid phase change materials suitable for thermal energy storage?
Various types of solid–liquid phase change materials (PCMs) have been reviewed for thermal energy storage applications. The review has shown that organic solid–liquid PCMs have much more advantages and capabilities than inorganic PCMs but do possess low thermal conductivity and density as well as being flammable.
Are phase change materials suitable for thermal energy storage?
Volume 2, Issue 8, 18 August 2021, 100540 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.
Why are solid–liquid PCMs used in energy storage applications?
Currently, it is mainly solid–liquid PCMs that are studied and used in energy storage applications because the solid–solid PCMs generally show smaller latent heat of phase transition. However, the solid–solid PCMs have the major advantages of a smaller volume change during the phase change than solid–liquid PCMS and they cannot leak . 3.2.1.
Are solid-liquid phase change materials a good candidate for large-capacity STES?

What is a phase change material?
A phase change material (PCMs) is a substance that undergoes a phase transition (change in its physical state) from a solid to a liquid or from a liquid to a solid at a specific temperature, often referred to as its melting point or freezing point 2, 3, 4.
Which type of energy storage process is not applicable to construction materials?
Depending on the type of PCM, energy storage process could be described as solid–solid, solid–liquid, liquid–gas or solid–gas as shown in Fig. 1, , , . However, liquid–gas and solid–gas processes are not applicable to construction materials due to their large volume and pressure change during phase change process.
