Fundamentals of high-temperature thermal energy storage, transfer

After introduction, this chapter follows the three principles (sensible, latent, and thermochemical) as headings. TES is a multiscale topic ranging from cost-effective material utilization (1) via design of a storage component with suitable heat transfer (2) to the integration of TES in an overall system (3) each subchapter on the three technologies, namely, sensible

Sensible heat

Sensible heat is heat exchanged by a body or thermodynamic system in which the exchange of heat changes the temperature of the body or system, For example, during a phase change such as the melting of ice, the temperature of the system containing the ice and the liquid is constant until all ice has melted. Latent and sensible heat are

An overview of thermal energy storage systems

Sensible heat thermal energy storage materials store heat energy in their specific heat capacity (C p). The thermal energy stored by sensible heat can be expressed as (1) Q = m · C p · Δ T where m is the mass (kg), C p is the specific heat capacity (kJ.kg −1 .K −1 ) and ΔT is the raise in temperature during charging process.

Latent Heat Energy Storage

Latent heat storage systems are often said to have higher storage densities than storage systems based on sensible heat storage. This is not generally true; for most PCMs, the phase change enthalpy Δh pc corresponds to the change in sensible heat with a temperature change between 100–200 K, so the storage density of sensible heat storage systems with

2.1. Sensible heat storage Sensible heat storage consists of heating a material to increase its internal energy. The resulting temperature difference, together with thermophysical properties (density, specific heat) and volume of storage material, determine its energy capacity (J or kWh): H C T sensible T p E V c T dT= (1)

Introduction to thermal energy storage systems

For sensible and latent heat storage, the lower and upper temperature limits determine the maximum storage capacity. In case of thermochemical heat storage, for example, using water and zeolite as working couple, the maximum capacity is not only determined by the adsorption and desorption temperature, but also affected by the humidity of the air.

Sensible heat storage is achieved by increasing (heating) or decreasing (cooling) the temperature of the storage medium.A typical cycle of sensible heat thermal energy storage (SHTES) system involves sensible heating and cooling processes as given in Fig. 3.3.The heating (or cooling) process increases (or reduces) the enthalpy of the storage medium.
