Thermal simulation design scheme for energy storage system

What are thermal energy storage systems?

There are various technological solutions acting as Thermal Energy Storage (TES) systems, which can find application at domestic level. In Sensible Heat Storage (SHS) systems, thermal energy is stored by heating or cooling a liquid or solid as water, sand, molten salts, or rocks, with water being the cheapest option.

How efficient is a thermal storage system?

The equivalent round-trip efficiency of the entire process is 85.17%, which is a high level for energy storage systems. The efficiency is achieved because of the appropriate match between the heat sources and the thermal storage media. To illustrate the thermal performance of the integrated system, an exergy flow Sankey diagram is shown in Fig. 7.

What is a ministor thermal energy storage system?

MiniStor is an innovative compact thermal energy storage system that combines TCM and PCM materials for year-round thermal storage for heating and cooling. It is characterized by a very high energy storage density, over 10.6 times higher than the density of equivalent water-based systems.

What factors limit the commercial deployment of thermal energy storage systems?

One of the key factors that currently limits the commercial deployment of thermal energy storage (TES) systems is their complex design procedure, especially in the case of latent heat TES systems. Design procedures should address both the specificities of the TES system under consideration and those of the application to be integrated within.

What is packed-bed latent thermal energy storage system with spherical capsules?

Nevertheless, there are few comprehensive studies on the packed-bed latent thermal energy storage system with spherical capsules (PLTES-SC). It is one of the most popular devices for numerical simulation, experimental research, and industrial application in the current TES system.

What are the three integration concepts of heat storage?

Krüger et al. identified three integration concepts by considering three heat storage technologies (i.e., molten salt thermal storage, steam accumulator, and solid media thermal storage).
