TES is classified and discussed in most of the literature based on the technologies: sensible heat storage (SHS), latent heat storage (LHS), and thermo-chemical heat storage (THS) 1 [21]. In addition to these three, a study by IRENA identifies thermo-mechanical energy storage (TMS), also known as mechanical-thermal coupled …
SHS has become the most developed and widely used heat storage technology due to its simple principle and easy operation [27, 28].The ideal SHS material should have good physical and chemical properties of large specific heat capacity, high density, high thermal conductivity, and low vapor pressure. ...
TCM storage has two major advantages. First, TCM''s have high energy density on material level (> 1 GJ/m 3 ). Secondly, the energy is stored loss free as long as the gas and the solid are stored separately. The major challenges for this technology are to improve the power output as solid-state reactions are slow and to guarantee cyclic stability.
The technology for storing thermal energy as sensible heat, latent heat, or thermochemical energy has greatly evolved in recent years, and it is expected to grow up to about 10.1 billion US dollars by 2027.

Therefore, energy storage technology has become a major topic for the transformation of an energy-saving and environment-friendly society [4]. Phase change material (PCM) is the material that can change the state of material and provide latent heat under the condition of constant temperature.
PCMs have little storage volume in latent heat storage systems and energy storage and conversion, and therefore, they are called latent heat storage materials [8]. In addition, thanks to the integration of PCMs into nanoparticles for solar energy systems, the charge/discharge rates of solar energy storage and conversion …
For instance, thermal energy storage can be subdivided into three categories: sensible heat storage (Q S,stor), latent heat storage (Q Lstor), and sorption heat storage (Q SP,stor). The Q S,stor materials do not undergo phase change during the storage energy process, and they typically operate at low-mid range temperatures [ 8, 9 ].
Thermochemical heat storage (THS) is a relatively new technology with much research and development on these systems ongoing. Among these storage techniques, THS appears to be a promising alternative to be used as an energy storage system [3], [4], [5]. THS systems can utilise both sorption and chemical reactions to …
Materials scientists, chemists, physicists and engineers face the demand of finding new materials (at low cost) that will provide power more efficiently or store energy (for example as heat, electricity or indirectly as a fuel) safely and at maximum density. Realising new materials design concepts will likely be essential.
The sorption heat storage technology involves at least two components: one as the sorbent and the other as the sorbate. upon contact, the sorbate undergoes a phase change that releases heat. This is the discharge process of a heat storage system that provides the energy for applications. The heat storage is achieved by a reverse process which ...
