Yeah absolutely, which happened with electric cars in the 90s. If todays EV push is any indication thought, with enough persistence and acceptance even big oil has to get on board or be left behind.

All it would require to avoid the pure ammonia smell at the pump is an airtight connection between gas tank and pump nozzle. That’s an off-the-shelf part already, making these tanks would be straightforward. The greater challenge would be designing a car-sized hydrogen engine of comparable power output. I’m no thermo expert, but this seems possible if the transference of ammonia to hydrogen can be quick enough to feed the engine as much H as it needs.

This can genuinely happen if it can be profitable. And that’s the kicker, it’s gotta be as profitable as gas or more.
