Not sure what I'm gaining out of this as I really haven't been a proponent of hydrogen in the first place, but the efficiency number is even a bit lower than I remember seeing quoted before, which I want to say was 43%. There's a reason why everyone isn't running to this solution.
I'm amazed ammonia is being used as a fuel source directly in any example. Vehicles running around with that in the tank in an accident could be a bigger disaster than anything else a vehicle can run on. It only takes one tank car of anhydrous ammonia on a train to get it labeled as an alert train. Anything that falls under TIH(Toxic Inhalation Hazard) accounts for this. It takes 20 loaded hazardous(for sake of putting a label on it, ethanol) of any other type to be labeled as a key train and that's still technically considered lower than an alert train. With enough anhydrous in close enough proximity it can be instant death.
