FAQS about The first ammonia based solar thermochemical energy storage demonstration

Can ammonia-based solar thermochemical energy storage be commercialized?

Author to whom correspondence should be addressed. The ammonia-based solar thermochemical energy storage (TCES) is one of the most promising solar TCESs. However, the solar-to-electric efficiency is still not high enough for further commercialization.

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).

Why is ammonia dissociated endothermically?

In the system, ammonia (NH 3) is dissociated endothermically as it absorbs solar energy during the daytime. The stored energy can be released on demand when the supercritical hydrogen (H 2) and nitrogen (N 2) react exothermically to synthesize ammonia. The released thermal energy can be used to heat a working fluid, e.g. supercritical steam.

Is exergy loss dominant in the ammonia-based thermochemical energy storage system?

The results show that exergy loss in the charging loop is dominant in the ammonia-based thermochemical energy storage system. Furthermore, the exergy losses of Heat Exchanger Eh,A, together with that of the re-radiation Er, play important roles in the exergy loss of the charging loop.

Are ammonia-based solar TCES feasible?

Nonetheless, the highest solar-to-electric conversion efficiency of the ammonia-based solar TCES ever reported is only 18% [ 34 ], which is not high enough to verify the feasibility of further commercialization [ 14 ].

Can ammonia synthesis produce supercritical steam?

Ammonia synthesis for producing supercritical steam in the context of solar thermochemical energy storage. In: Solarpaces 2015: International Conference on Concentrating Solar Power and Chemical Energy Systems, p. 1734. Chen, C., Lovegrove, K., Kavehpour, H.P., Lavine, A.S., 2016b.
