Although device designs are application dependent, general design principles for improved thermal storage do exist. First, the charging or discharging rate for thermal energy storage or release should be maximized to enhance efficiency and avoid superheat.
The different technologies for heat storage and recovery There exist different types of thermal energy storage systems. These are the three main types of storage: Sensible heat storage is the most widely used. Water is often used as a carrier, since it has one of the highest volumetric heat capacities of natural existing materials.
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.
Thermal energy storage in the form of sensible heat relies on the specific heat and the thermal capacity of a storage medium, which is usually kept in storage tanks with high thermal insulation. The most popular and commercial heat storage medium is water, with a number of residential and industrial applications.
For example, combined heat and power (CHP) systems for recovering and using waste heat can synchronously generate electricity and heat.86 To regulate the heat load from the CHP system, a dynamic thermal storage strategy is desired to enable an enhancement by considering the transient waste heat and dynamic electricity generation.
However, sensible heat storage requires in general large volumes because of its low energy density, which is 3 and 5 times lower than that of PCM and TCS systems, respectively. Furthermore, sensible heat storage systems require proper design to discharge thermal energy at constant temperature.
