I look every so often at the progress in the power to liquid fuel research,
and came across this piece of research.
Nitrogen-Based Fuels: A Power-to-Fuel-to-Power Analysis - Grinberg?Dana - 2016 - Angewandte Chemie International Edition - Wiley Online Library
Storing hydrogen attached to nitrogen, has some merits, in that nitrogen is easy to capture,
I question them saying that ammonia is non toxic, perhaps less than gasoline, but still very toxic.
I have read that people converted vehicles to run on ammonia during WW2 fuel shortages,
I suspect it would not be much different that liquid propane.
Everyone could tell if something was leaking!
I think those are best left in reserve for future generations.:mrgreen:Is there a possibility we could start mining all those dirty disposable diapers?

Fair enough, but not the lowest hanging fruit.It's a renewable resource.

You can burn ammonia in an IC engine also, (but I suspect you may need different lubricates)Well, There is an article here about using NH3 as a source for fuel for fuel cells https://www.sciencedirect.com/science/article/pii/S1364032116001611
If NH3 is able to be used as a fuel cell, the byproducts woudl be nitrogen gas and water. That would solve the following problems.
1) The release of Co2 into the atmosphere.
2) The storage of hydrogen and the ability to transport it, and fuel the vehicle.
The issue then would be making the ammonia, and how much energy you can get per gallon. The thought is interesting though.

I think incomplete fuel burning would create a smelly mess.
I favor carrying hydrogen has a hydrocarbon, but mostly because our current infrastructure
is compatible. Man made hydrocarbons could be carbon neutral as well.
Not at atmospheric pressure, more like liquid propane, but also could have negative effects on o-rings, seals, pumps, ect.The current infrastructure would be able to handle liquids.. and ammonia is a liquid.

?, ammonia is a gas at atmospheric pressure, what you do with it, does not matter.Only if used in IC engines.

As to the negative effects of ammonia being a caustic agent, that would have to be considered
no matter what the application was.
I am not sure if household ammonia burns,(I never actually tried, which is odd, I guess the smell bothered me.)You are right. I am just thinking it's dissolved in water for cleaning purposes..
The current infrastructure would be able to handle liquids.. and ammonia is a liquid.
But unlike conventionally fueled vehicles, ammonia-powered cars would not emit carbon dioxide. Most cars on the road can run on a mixture of 90 percent gasoline and 10 percent liquid ammonia, and could be modified to run on a mixture of up to 80 percent ammonia—at a cost of $1,000 to $5,000 per vehicle.

The whole key would be getting enough ammonia from a non-carbon source.
The 2 raw materials required to make ammonia are nitrogen from the air & hydrogen from methane separated from natural gas. Methane is a bad actor in itself because it is far more potent as a greenhouse gas than is CO2. So converting it into motor fuel that leaves no carbon exhaust is a good thing IMO.
Well, with new cheaper catalysts, the amount of energy and speed for electrolysis might make using electrolsys and solar panels to be less expensive than using methane. The use of methene puts hydrogen costs about 2.75 per kilo from methane.
The second generation goal for the device will be just slighly lower than that. That would make it in line cost wise.
