“…This kind of thermo-chemical heat storage system has been investigated theoretically and experimentally by several authors focusing on solar thermal power applications or the use of process heat (Bauerle et al, 1976;Fujii et al, 1985;Brown et al, 1991;Schaube et al, 2011), heat pumps (Ogura et al, 1999(Ogura et al, , 2002, preheating of engines (Darkwa, 1998;Azpiazu et al, 2003), and even power generation on the moon (Perez- Davis and DiFilipo, 1990). Requirements are a specified system integration to minimize parasitic losses, e.g.…”

Thermal energy storage has very important prospects in many applications related to the use of renewable energies (solar energy, etc.) or other energy sources, such as waste heat from industrial processes. Thermochemical storage is very attractive for long-term storage, since it could be conducted at room temperature without energy losses. In the present paper, a novel nanocomposite material, Ca 2−α Znα(OH) 4 , is prepared using coprecipitation methodology and is characterized by XRD and DSC tests. The XRD result shows that the grain size of the nano-composite ranges from 40 nm to 95 nm. The DSC test result shows that the nano-composite exhibits high thermal storage capacity: 764.5 J/g at α = 0.8555. Its thermal decomposition temperature was found to be approximately 180 ∘ . It was found possible to recover 63.25% of the stored heat energy.

“…Zondag et al [12] characterized magnesium sulphate as a storage media and examined the cycling behavior of MgSO 4 and the dehydration temperature of the reactant. Thermal energy storage based on the Ca(OH) 2 and CaO cycle is another example of thermochemical energy storage, and the reversibility and efficiency of this system was investigated in Azpiazu et al [13]. Thermochemical energy storage based on the chemical pair ammonia and water has been investigated in conjunction with a solar thermal plant.…”

Thermal energy storage (TES) is an advanced technology for storing thermal energy that can mitigate environmental impacts and facilitate more efficient and clean energy systems. Thermochemical TES is an emerging method with the potential for high energy density storage. Where space is limited, therefore, thermochemical TES has the highest potential to achieve the required compact thermal energy storage. Thermochemical TES is presently undergoing research and experimentation. In order to develop an understanding of thermochemical TES systems and to improve their implementation, comprehensive analyses and investigations are required. Here, principles of thermochemical TES are presented and thermochemical TES is critically assessed and compared with other TES types. Recent advances are discussed.
