Thermochemical Energy Storage Power Station Design

What is thermochemical energy storage?

Thermo-chemical energy storage is a key technology to realize highly e cient short and long term thermal energy stores for various applications such as solar thermal systems or cogeneration systems. By storing the energy in form of chemical bonds of special materials the energy can be stored almost loss-free over arbitrary time periods.

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.

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 .

Can a thermo-chemical energy store be integrated in a solar thermal system?

process design, the CWS-NT-concept for a thermo-chemical energy store integrated in a solar thermal system has been presented in this paper. An essential part of the thermo-chemical energy store is the reactor where the heat and mass transfer take place.

Are thermochemical energy storage systems a viable alternative to molten salt-based storage?

Dispatchability is a key issue to increase the competitiveness of concentrating solar power plants. Thermochemical energy storage systems are a promising alternative to molten salt-based storage because of the higher energy storage density and the possibility of increasing the storage period.

What is thermal energy storage?

Thermal energy storage (TES) is an integral part of a concentrated solar power (CSP) system. It enables plant operators to generate electricity beyond on sun hours and supply power to the grid to meet peak demand. Current CSP sensible heat storage systems employ molten salts as both the heat transfer fluid and the heat storage media.
