I am amazed by scientific progress as ever - and actually feel this is weirdly one of those papers where I stand a tiny chance of even being able to replicate it. It's just that might be the problem (if it scales). Isn't ammmonia the basic input to high explosives (I know it goes something like Fritz Haber -> Ammonia -> feed world / blow up shells), there is I expect a bit in the middle, generally fuel oil and fertilisers.
