WoW .. well that explains why the guy I mentioned earlier, was storing H2 in a row of 1,000 gallon propane tanks, at a pressure that they are rated for as I recall. Certainly not liquefied. 33 Kelvin is damn cold. So even a remote pv powered H2 station would have limitations insofar as a reasonable storage capacity.
The SEER '91 vehicle used some substance in the tank that absorbed H2 at a greater density .. just too long ago to remember what is was .. but similar in concept to the chicken feather nano-carbon.
Generation .. storage .. distribution .. and user base .. many challenges. Thanks for de-simplifying the motors/pumps realities.
