Sure, its carbon free, but NOx (NO, NO2, N2O etc) are really terrible greeenhouse gases and one of the main causes of smog. Catalytic convertors are there just to address this and try to mitigate the problem since all fuel contains a small amount of nitrogen compounds. Let's hope they don't replace one GHG with another.

I think it's a closed system, fuel cell, no?

I'm not buying this at all.

People freak out about EV battery fires now (never mind that this is not actually the problem it is made out to be), can you imagine the hazmat situation from a couple of cars carrying who knows how many KG of Anhydrous Ammonia crashing into each other? I mean, you might make the fuel tanks extremely robust (and heavy) but fuel lines etc will still break. Ammonia in the air at 300 PPM will cause SEVERE injuries to anybody in the area not wearing a respirator.

And how are you supposed to fuel these cars? Have you seen the PPE you have to wear when handling Anhydrous Ammonia?

Plus the level of technical protection necessary for refueling. With gasoline, you spill-proof the floor, maybe suck off the fumes, that's it. With ammonia, all connections have to be air-tight. You'll have to vent the tank through a pressure-relief line and then condense the ammonia, because you must not release it into the atmosphere. Ammonia spillage will eat through concrete, many metals and tarmac, so either you get very expensive high-grade stainless steel floors or very expensive ammonia-proof plastic floors. And your ammonia-refueling-station will still stink to high heaven...
