If you can acquire hydrogen economically, it can be converted to ammonia cheaply.

For many industrial processes, ammonia is a well-established common feedstock, having none of the issues of hydrogen you mention.

Here in Japan, some Combined Cycle Gas Turbine plants are already running with 10% ammonia blend.

I think you are right about pure hydrogen, but I can see green-hydrogen-into-ammonia as viable for many applications including heavy transportation (train, ship, truck).

We just need much more economic electrolysis, because hydrogen is almost always produced from fossil fuels today.
