Ammonia synthesized electrically is not restricted in how it may be used. Identically the same ammonia will be used for many things: burned in combined-cycle turbines for power, burned in retrofitted cargo ships displacing bunker oil, made into fertilizer, injected as working fluid into warehouse-scale refrigeration systems, dissolved in water for window cleaner, used as feedstock in a thousand other chemical pipelines, sent abroad in tankers, mixed into hydrogen fuel to scavenge NOx. It is exactly its wide usefulness that makes it attractive. Similarly for hydrogen.

Insisting that a synthesis plant must jealously direct every last liter produced to be tanked and later burned in a local peaker turbine is fetishism. The ammonia doesn't care, and neither does the synthesis equipment owner: any customer who pays is a good one.
