What is a third phase of chemical reactions for thermal energy storage?

Therefore a third phase of chemical reactions for thermal energy storage can be added: 3. Storage of thermal energy due to suppression of the exothermic reaction. Since the thermal energy is stored as ‘chemical potential’, the storage duration is in principle infinite and is only limited by economic constraints.

What is the storage of energy through reversible chemical reactions?

The storage of energy through reversible chemical reactions is a developing research area whereby the energy is stored in chemical form . In chemical energy storage, energy is absorbed and released when chemical compounds react.

Do chemical reactions affect thermal energy storage?

Summarizing the main characteristics of chemical reactions for thermal energy storage, it can be concluded that the higher system complexity of chemically based storage systems demands an additional benefit in comparison to physical storage principles.

What is chemical energy storage?

Chemical energy storage is defined as the utilization of chemical species or materials to extract energy immediately or latently through processes such as physical sorption, chemical sorption, intercalation, electrochemical reactions, or chemical transformation.

Can a chemical heat pipe be used as a thermochemical heat storage system?

If the products of the endothermic reaction are stored, the chemical heat pipe can also be operated as a thermochemical heat storage system, thereby combining both a distribution possibility for thermal energy that is in principle free of losses as well as a thermochemical energy storage.

What are the key factors for chemical energy storage materials?

The key factors for such kinds of chemical energy storage materials are as follows: Large density; Easy to store and transport; Compatible to the existing infrastructure; Easy to produce and high round-trip efficiency; Environment friendly.

Even though the expression ‘chemical or thermochemical storage’ is widely used for storage systems involving any interaction between two or more components for thermal energy storage, this chapter focuses solely on reversible chemical reactions and their special characteristics.
