[TheForge] Hydrogen storage (was: Hellooooooo!)

[Bruce Freeman]

Other technologies than presurization or liquification seem more
promising.  Metal hydrides.  Adsorbed hydrogen.  I'm not up on the
details, but these ideas offer the possibility of much denser hydrogen
storage.

I suspect, however, that the minute cheap hydrogen becomes available,
someone will come up with a neat method of combining it with coal, maybe
even underground coal, to produce hydrocarbons - propane, butane,
gasoline, or diesel fuel.  This won't fix the greenhouse gas problem,
but will make a hell of a lot more "petroleum" available right here in
the hew hess of hay.

As was pointed out today on another list I am on there is a rather  
significant problem with hydrogen power. It takes about 320 cu ft of  
hydrogen at atmospheric pressure to equal the BTU's in a gallon of  
gasoline. One of the large pressurized gas cylinders holds about 300  
cu ft at 2300 psi you would need 15 of those to be about equivalent  
of 15 gallon gas tank, each one is about 100 lbs mass so carrying  
enough hydrogen to power your car over any significant distance is a  
big logistical problem.  Go to http://mb-soft.com/public2/ 
hydrogen.html and read. There are technologies being discussed to  
make it where you could cary a greater volume of hydrogen but I am  
not feeling wonderful about 5000 psi gas cylinders or tanks of liquid 

hydrogen in my car in an accident.

It sounds like a great idea but there are some significant problems  
to be overcome before you will be filling up with hydrogen
