Thermal storage metal cycle energy storage device

What is thermal energy storage technology?

Thermal energy storage (TES) technology is playing an increasingly important role in addressing the energy crisis and environmental problems. Various TES technologies, including sensible-heat TES, latent-heat TES, and thermochemical TES, have been intensively investigated in terms of principles, materials, and applications.

How to design a thermal energy storage system based on metal hydride materials?

To effectively design and build a thermal energy storage system based on metal hydride materials, different processes need to be examined in detail using models that include momentum, mass, and energy transport, coupled with the kinetics and thermodynamics of the reacting materials.

How is thermal energy stored?

Thermal energy can generally be stored in two ways: sensible heat storage and latent heat storage. It is also possible to store thermal energy in a combination of sensible and latent, which is called hybrid thermal energy storage. Figure 2.8 shows the branch of thermal energy storage methods.

How do thermochemical heat storage systems work?

Thermochemical heat storage (TCS) systems use chemical reactions to store and release thermal energy. The energy storage process of TCS materials comprises three phases, namely, charging, storage and discharging. During charging, energy in the form of heat is provided to the TCS material, which then undergoes an endothermic reaction.

How a thermal energy storage system works?

For example, if the aim of the thermal energy storage is to store solar energy, charging period will be the daytime for daily storage and the summer for seasonal storage. The solar energy is converted to the heat in solar collectors and charged into a storage medium like water, rock bed, phase change material, etc.

What are the three types of thermal energy storage systems?

The three types of storage systems, being developed today, can store thermal energy as (1) sensible heat, (2) latent heat from material phase change, or (3) thermochemical energy, using the heat released (or absorbed) during chemical reactions occurring inside the material [3, 8].
