I don't know .... if you look at hydrogen fuel as an energy storage mechanism, then using hydroelectric power to manufacture hydrogen from sea water could make sense. I haven't looked at the relative efficiency of hydro electric transmission systems (i.e. big whacking wires) vs conversion to hydrogen and then pipeline transport to the point of use but all that does is change the location of the hydrogen manufacturing plant. In vehicles it's all about usable energy stored vs weight of storage mechanism, whatever technology comes out on top in that department should win the prize once fossil fuels are either gone or too expensive to use anymore.
