Can anyone confirm that this is simply a way to package hydrogen into a safe transportation medium to international markets (from Australia as an example) and then converted back to hydrogen when it reaches the target country?

Put it this way, is it converted back to hydrogen before it’s pumped into the car? I kinda like the idea of ammonia being converted into hydrogen in the car but judging from the news reports we have seen here in Australia the membrane technology looks quite large... more something one would see in a refinery than a car.

So my question is: at what stage would the ammonia be converted back to hydrogen; at a refinery, the service station or in the car itself?

Since there are already hydrogen fuel cars available from reputable manufacturers who (I assume) would be hesitant to add a fairly complicated component into their production vehicles, it might be easiest to transport liquid ammonia to car fill stations at which point it would be converted to hydrogen before going into the cars.

You would want to do the conversion as late as possible, hydrogen is difficult to store [1].

Cars are far from the only potential consumer. Sure, you might also use some of the hydrogen to power cars with fuel cells. Or you use it to charge EVs. Or you use the ammonia directly for grid electricity and heating. Or industrial processes.
