I'm surmising that it could be a useful first step towards converting the atmospheric CO2 into something easier to store long-term.
So the ammonia doesn't need to be useful in itself, but only to be able to be converted on-site to something more storable (more stable, liquefaction at lower pressure or higher temperature, and so on), or alternatively something more useful that could displace other standard CO2-intensive industrial processes.

Ammonia is NH3, there's no CO2 to store.

Except they are talking about using it as a fuel. If you want to displace CO2 at least use methanol, it's a liquid that's more energy dense and easier to handle safely.
Oops, you're right...
In this case the environmental significance of producing ammonia is much less impressive...
