There is an entire industrial infrastructure in many agricultural nations that manufactures, distributes, and fertilizes with liquid anhydrous ammonia. All the necessary tech to get this into a vehicle without killing anyone already exists.

And it's regulated way more than the fuel industry. In many of those developing nations, opening a gas station is as simple as burying a few containers and paying off fire-safety inspectors. I'm not at all eager to see them handling ammonia that way.

From what I've seen of "developing nations", a "gas station" is a roadside hut with a shelf of liter-size glass bottles and a skinny dude to pour the bottles into the tank of your motorcycle. Obviously no one would handle pressurized liquid ammonia in that fashion, because it isn't physically possible. One wouldn't imagine that developing nations are the target market for this anyway. The point is that lots of people know how to handle ammonia, and if the market expanded lots more people could learn. If we're serious about reducing carbon emissions (frankly that's an open question), what would be so terrible about bringing back filling station attendants?

And then there is BRICS--countries that have the means to use the modern tech, but the governments are too weak or too corrupt to enforce regulations.

This tech has its merits, if done right it can increase the overall efficiency of hydrogen tech, however carrying kgs of ammonia in consumers' cars or tons of it in local gas stations when mere grams can kill you is pushing it too far.
