> Electric ammonia synthesis plants are right now under construction all over the world.

Source? I'm not finding any result for electric ammonia synthesis plants under construction right now.

The best I could find is this [1] but it's not a plant under construction, and there still significant challenges to overcome to make this viable.

Those engineers have opted not to build any of the storage systems you listed. I agree they're not idiots.

Your search skills do not define the limits of investment or build-out.

There are no ammonia electric storage plants under construction. You write that there's many under construction, all over the world. Yet you fail to identify one such plant that's actually under construction.

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.
