conversion cost. Also Hydrogen storage is non-trivial : in a pressure tank one must assume pressure loss due to smal sinngle hydrogem atoms diffusing through the walls ( and possibly doing structural damage to the steel while doing that http://en.wikipedia.org/wiki/Hydrogen_embrittlement) The material one needs to store without big pressure are costly and rare. If one wanted to store the energy and had unlimited synthetic capability then producing methanol ( CH3OH ) or ethanol (CH3CH2OH) wuld make more sense they could be stored without pressure and one would take CO2 from the atmosphere too.
Without researching the processes involved I would be surprised if one could get 50 percent of the original wind /solar/tide energy from Hydrogen generated ( and that is not including the inefficiency of internal combustion engines ). http://en.wikipedia.org/wiki/Hydrogen#Energy_carrier.
What the world obviously needs is Shipstones: RAHs answer. (Friday ) - however I have studied just enough physics to doubt that it is possible.
Admittely the transportation of electricity has a lot of loss to it - otoh one should not forget the power industry WOULD go for more economic distribution if there was any.
