Can thermochemical thermal energy storage systems be used in power-to-heat applications?

In this work, a comprehensive review of the state of art of theoretical, experimental and numerical studies available in literature on thermochemical thermal energy storage systems and their use in power-to-heat applications is presented with a focus on applications with renewable energy sources.

What is thermochemical energy storage?

Typically, thermochemical energy storage refers to two main processes, thermochemical reactions and sorption processes. Thermal adsorption reactions can be used to store heat or cold in the bonding of a substance to another solid or liquid. A common sorption process used in TCS systems is the adsorption of water vapor to silica gel or zeolites.

Why do thermochemical thermal energy storage systems have a high energy density?

High energy density makes thermochemical thermal energy storage systems (TCTESs) such more compact energy systems so their use, reducing the volume of the system, could be very effective in the situations whereas space constraints are significant .

Why is thermal energy storage important?

Challenges and prospective researches of TCES system are elaborated. Thermal energy storage can provide cost-effective benefits for different commercial fields because it allows heat recycling for use, such as in concentrated solar power plants or metallurgical and steel plants.

What are the limitations of thermochemical storage systems?

Although thermochemical storage systems possess high energy densities and longer periods of energy storage without much loss, their cost, slower kinetics, operational conditions, etc., limit their application [2,32,40]. 2023, Power Generation Technologies for Low-Temperature and Distributed Heat Maria Elena Navarro Rivero, ...

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.
