Ammonia thermochemical energy storage

Can an ammonia synthesis system be used for thermochemical energy storage?

This paper has investigated the design of an ammonia synthesis system for thermochemical energy storage. A parametric study was conducted to investigate the effects of geometries, mass flow rates, and inlet temperatures on the required wall volume of the heat recovery reactor (HRR) and autothermal reactor (ATR).

What is ammonia-based energy storage system?

High round-trip efficiency, low cost, and considerable flexibility are desirable. To this end, an ammonia-based energy storage system is proposed. It utilizes a pressurized reversible solid-oxide fuel cell for power conversion, coupled with external ammonia synthesis and decomposition processes and a steam power cycle.

Why is ammonia an attractive energy storage system?

Ammonia offers an attractive energy storage system due to its well-established infrastructure. Ammonia showed great promise as a viable hydrogen fuel carrier. Energy can be stored in the chemical bonds of ammonia through the endothermic ammonia synthesis reaction. Ammonia can be used as a fuel in fuel cells and internal combustion engines.

Can ammonia store solar energy thermochemically?

Out of the many TCES media, ammonia has been understudied the longest. Nowadays, studies are looking into using ammonia to store solar energy thermochemically . Revisiting Eq. (1), it is clear that the synthesis of ammonia involves an exothermic reaction, while the reverse reaction is, naturally, endothermic.

Is ammonia a reliable energy storage medium?

Ammonia energy storage (AES) systems As discussed in section 1.3, ammonia has many advantages of being a reliable energy storage medium. It is a clean chemical and does not contribute to GHG emissions. Ammonia can be used in energy applications in a number of ways, some of which are discussed in the following sections.

How can ammonia be used in energy applications?

Ammonia can be used in energy applications in a number of ways, some of which are discussed in the following sections. There are several energy storage systems, including electrical (supercapacitors), electrochemical (e.g., batteries), mechanical (e.g., compressed air), and chemical (e.g., ammonia).
