> Ammonia does not have any of these problems

Ammonia is a greenhouse gas itself, and it tends to react with air creating various nitrous oxides, that are much more potent greenhouse gases than methane, very toxic, and create acid rain (after what it becomes fertilizer).

The best shipping option is probably just to face all the issues and ship the hydrogen. But storage is a different matter.

Ammonia is no greenhouse gas, it has a GWP of zero. Burning ammonia produces N2O, which is a potent greenhouse gas, and NOx, which is an air pollutant. But these can be taken care of by scrubbers, and are irrelevant if you ship ammonia for other uses. (I mean the biggest use case of hydrogen these days is making ammonia for fertilizers.)
