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.

Is thermochemical heat storage a viable option for building heating demand?

Solar energy utilization via thermochemical heat storage is a viable option for meeting building heating demand due to its higher energy storage density than latent or sensible heat storage and the ability for longer duration storage without loss because energy is stored in chemical bonds.

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.

Is thermochemical energy storage a key technology?

Thermochemical energy storage could be a key technology able to bridge the gap between the wasted heat as the source and provided to customers at the time and place they need it [267, 268]. A more detailed review on this field was developed in .

What is thermochemical energy storage (TCES)?

Compared to traditional sensible and latent energy storage, thermochemical energy storage (TCES) offers a greater possibility for stable and efficient energy generation owing to high energy storage densities, long-term storage without heat loss, etc.

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 .
