yeah i know, right now it's mostly made from that gas liquer and really, when you think of it, it would be backassward to even try to get hydrogen from that ammonia-- since the natural gas has to be hydrogenated...
but i was thinking more about it in a disaggregated transportation-market kind of way ((But what is so much more inconvenient to work with for say, a car on H2 than a car with CNG?)) ..and also thinking like, ammonia like the mountainous industrial animal waste's ammonia, and even cities could use it for their ammonia from our poo. a city could do it with our waste instead of having to do crazy stuff like this:

Oh, yeah, H2 is a HUGE pain in the ass compared to CNG. Density is much lower, and liquification requires much lower temperatures (around 6K, IIRC).
When I was a rocket engineer, we intended to use kerosene as a fuel rather than hydrogen because a tank large enough to hold sufficient (liquid) hydrogen would have been bigger than the vehicle.
Sewage is certainly a resource worth tapping, but I'd suggest a simpler, low-tech approach: an anaerobic digester to make methane.
Phew! I'm sure glad i didn't say "it's not rocket science"scalarpartyAugust 7 2007, 23:33:57 UTC
it's not it making it, or storing it right? just once it would be in the vehicle that the temperature's a problem, right? cause we make around 50 billion tons of it now for potato chip oil, metals processing & refining, chemical production, like the amonia and electronics processing. thats enough to fuel 250 million fuel cell cars right now.
as far as not losing the H when you're driving, you know me i'm a hopeful puppy, i believe that the good folks at BMW have been on it all along, and never given up with IC Hydrogen. and have solutions to keeping that liquid hydrogen squishee nice and cold (and no rubber tubes i'm sure). i believe in their sexy bi-fuel BMW 745h. but now am worried both about the size of the tank your projecting, and that someone who was building a space-helicopter is reading this LJ [uh-oh]

..and FORD was just up here in canada using a bunch of Quantum-ified hydrogen shuttle buses to shuttle around all of these Parliamentarians ...and they just finished doing a month of sightseeing tours in florida
Hmm, if Frank Neukomm is on board, there must be something good that will come of this? It sounded so promising when I read it on first post, but your back and forth with a_steep_hill makes it sound less so. Your tech talk is over my head! LOL. In simple terms, what's the bottom line?
the bottom line?scalarpartyAugust 9 2007, 15:56:25 UTC
who knows? Sorry Bird, i wish i had a better answer for you... i think it may be a cool tech --this hyrogen from amonia if used from poo and other waste streams (not from natural gas)
I asked because I read so many things that sound like "Wow, great, this will save the world from peak oil!!" And then someone in the know says "No, that won't work because of x-y-z..." It's hard to know the bottom line!

H2 is an energy carrier, nothing more. And it's a damned inconvenient one to work with for most purposes.
