Energy conversion of thermochemical energy storage

What is thermal energy storage & conversion?

Thermal energy storage and conversion aims to improve the high inefficiency of the industrial processes and renewable energy systems (supply versus demand).

Can thermochemical energy storage close the energy supply-demand gap?

The thermal energy storage (TES) technology has gained so much popularity in recent years as a practical way to close the energy supply–demand gap. Due to its higher energy storage density and long-term storage, thermochemical energy storage (TCES), one of the TES methods currently in use, seems to be a promising one.

What are thermochemical energy storage systems?

While the focus is on low-temperature applications such as residential heating, thermochemical energy storage systems are also being considered for industrial waste heat applications or for solar thermal power plants, with TCES seen as a promising option for high-temperature systems [Pardo2014].

What is thermochemical energy storage (TCES)?

This chapter introduces the technical variants of TCES and presents the state of the art of this storage technology. Thermochemical energy storage (TCES) is considered the third fundamental method of heat storage, along with sensible and latent heat storage. TCES concepts use reversible reactions to store energy in chemical bonds.

What is thermal energy storage & conversion (tesc)?

In this sense, thermal energy storage and conversion (TESC) can increase the thermal energy efficiency of a process by reusing the waste heat from industrial processes, solar energy or other sources.

What is the energy storage density and heat transfer coefficient?

The obtained energy storage density and overall heat transfer coefficient were 213 kWh/m 3 and 147 W/m 2 K, respectively. Recently, Xu et al. characterized two composite materials (zeolite-13X/MgSO 4 and activated alumina/MgSO 4) using a closed loop TCES system.
