I suspect the reason why you don't see many 300 bar tanks in the US is 
that they require a DIN valve, and as far as I know those are not very 
popular in the US (or anywhere else outside of Europe).

DIN valves have actually several advantages. They are stronger (which 
is the reason why you can have a 300bar variant) and more compact, the 
o-ring is better protected and stays with the regulator, not the tank 
(which is a nice advantage when using your own regulator on rental 
tanks).
