Thermophysical heat storage for cooling, heating, and power generation ...
Thermophysical heat storage is a general term to effectively combine sensible heat and latent heat storage. In particular, both sensible heat and latent heat appear when using PCM for TES, as shown in Fig. 1. The sensible heat and latent heat are derived from the temperature change and phase change, respectively.

The pilot-scale latent heat storage system was part of a combined latent heat/sensible heat storage system with a total capacity of 1 MW, and the maximum capacity of the latent heat storage system was to be in the range of 700 kW. The storage capacity was to be about 700 kWh, requiring 14 t NaNO 3 with a volume of 7 m 3.
Sensible heat
The sensible heat of a thermodynamic process may be calculated as the product of the body''s mass (m) with its specific heat capacity (c) and the change in temperature (): =. Joule described sensible heat as the energy measured by a thermometer. Sensible heat and latent heat are not special forms of energy. Rather, they describe exchanges of ...
Thermal energy storage
The different kinds of thermal energy storage can be divided into three separate categories: sensible heat, latent heat, and thermo-chemical heat storage. Each of these has different advantages and disadvantages that determine their applications. Sensible heat storage. Sensible heat storage (SHS) is the most straightforward method.

Sensible and Latent Heat Thermal Energy Storage
In addition, depending on the energy storage method deemed, TES solutions can be classified into three categories, viz., sensible heat storage (SHS), latent heat storage (LHS) using PCMs and thermochemical heat storage (TCHS). Moreover, these classes can be implemented in active or passive buildings [ 16][ 17].

What is Latent Heat Storage
The comparison between latent heat storage and sensible heat storage shows that in latent heat storage storage densities are typically 5 to 10 times higher. In general, latent heat effects associated with the phase change are significant. Latent heat, known also as the enthalpy of vaporization (liquid-to-vapor phase change) or enthalpy of ...

Each method of energy storage holds some basic advantage over others and is also associated with some drawbacks. Storing energy as sensible heat or latent heat is simple and relatively cheaper []; however, it cannot be stored for longer periods in these forms [] has to be used within certain period of time after storage since it is lost to …
Global prospects and challenges of latent heat thermal energy storage ...
SHTES utilizes sensible heat which is stored in material due to change of temperature to store energy. The energy storage density of latent heat TES (LHTES) is multiple times higher than that of sensible heat TES, and latent heat TES is more stable than thermochemical TES (Zanganeh et al. 2014; Zheng et al. 2018). So evidently, the …
Design of sensible and latent heat thermal energy storage …
The total storage volume was estimated by the ratio of total storage capacity to sum of latent heat and sensible heat of the storage medium within the same top and bottom temperatures in the two-tank system. Under this design condition, all 45 designs showed reduced annual electricity output compared to the two-tank system. ...
Latent Heat Thermal Energy Storage
5.2 Latent Heat Thermal Energy Storage. Better choice than sensible heat TES is latent heat TES with phase change materials (PCMs) [52,53]. Some implementations are reported in Sharma et al. [54] and Lecuona-Neumann [49]. Melting the PCM stores energy at a constant temperature, which is given back when solidifying.

It means that the latent heat storage has higher energy storage density in a smaller volume, or less material usage, in comparison to sensible heat storage. The latent heat of evaporation of water has the order of 2 MJ/kg which is almost ten times that of the solid-to-liquid transformation.
A Comprehensive Review of Thermal Energy Storage
For water heating, energy storage as sensible heat of stored water is logical. If air-heating collectors are used, storage in sensible or latent heat effects in particulate storage units is indicated, such as sensible heat in a pebble-bed heat exchanger. In passive heating, storage is provided as sensible heat in building the elements.
