My two cents ...
I think that it is important to call this hydrogen transport medium "anhydrous ammonia" which is the proper name...
Secondly, it is important to recognize the unique transportation and storage hazards of anhydrous ammonia. There is a special type of cracking induced into carbon steel when in long term contact with AA. Also, storage of AA usually is at 250 psig which implies large, thick pressure vessels and piping
Thirdly, unless you want to have a massive number of trucks or railcars transporting large quantities of this stuff, then the new hydrogen economy is not going to happen. ..... That leads us into the only practical solution ... AA pipelines !!!
Recall that the current administration is against underground pipelines ..... but only the pipelines that transport "bad" things, like petrochemicals ..... not the pipelines that may transport "good" things .... in support of the vision of the new economy
Lastly, if you want to see a real environmental mess, break into a high pressure AA pipeline. Its at least as hazardous as any crude oil transport pipeline..... IMHO
Will the anhydrous ammonia lobby be advocating a new system of pipelines ?????
Anybody else out there add anything ???
