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.

Why do we need a phase change material for heat storage?

Heat storage efficiency is required to maximize the potential of combined heat and power generation or renewable energy sources for heating. Using a phase change material (PCM) could be an attractive choice in several instances.

What is phase change energy storage?

The phase change material must retain its properties over many cycles, without chemicals falling out of solution or corrosion harming the material or its enclosure over time. Much research into phase change energy storage is centered around refining solutions and using additives and other techniques to engineer around these basic challenges.

How to determine the heat storage capacity of a cascaded phase change material?

By continuously heating the water tank, the material temperature change and phase change time were tested to determine the heat storage capacity of the phase change material, as shown in Fig. 4, thus quantitatively portraying the heat storage capacity of the cascaded phase change material, as shown in Table 2.

What is phase-change thermal storage technology?

Phase-change thermal storage technology can solve the issue of mismatch between the supply and demand of heat on a time scale. The heat collected during the heat-storage period can be transferred to fill the heat gap during the middle of the heating period.

Can phase change energy storage be used in residential spaces?

BioPCM brand phase-change material installed in a ceiling. This is used as a lightweight way to add thermal mass to a building, helping maintain stable comfortable temperatures without the need for continuous heating and cooling. Looking to the future, it may be that phase change energy storage remains of limited use in the residential space.
