Hydrogen vs. Battery Electric Cars

You don't have to go farther than 5 pages in the government DOE web page re: H2 as a "fuel" that H2 is so unstable in an oxygen-rich atmosphere that it really does not exist anywhere on the earth in any reasonably exploitable quantity and the "obvious" means to extract H2 using electrolysis is a 6:1 "energy sink" (that is, it takes 6 times the energy to dissociate the very stable H2O into one O2 and the yielded two H2 has in it when you are done) so you start out with a negative energy that can't be overcome with any level of efficiency (an inescapable nod to entropy). Therefore, H2 viewed as a "fuel" (stored energy medium) does not make sense at the outset (except for necessity such as space habitation where you can get warm, clean H2O, some electrical power back and have extra needed O2 on board in another tank). The history (as I understand it) is, at the outset of the automotive emissions regulations (mid 1960's), the question was asked of the smartest minds (space engineers), "How low can emissions go?" (wishing to eliminate poisonous NO, CO and toxic unburned hydrocarbons). The scientists proclaimed that, using H2 (as a "fuel") and O2 as an oxidizing agent, the emissions can be benign warm H2O. This started the talk of H2O as a "fuel" but the "energy sink" reality ends the feasibility unless there is another CO2-free way (nuclear?) to create the hydrogen but, as stated, it is untenable unless the requirement is emissions at the vehicle and wholly inefficient unless cost is no object (space program). Without this in place (it is not) for dedicated service (again, not), there are better uses of electricity than to carry on the "H2 as a fuel" myth. Perhaps there are some out there who have those answers (or better sources for H2 extraction/yield in the works). Until then, I don't understand why there is still a discussion that includes H2 (vapor-ware). Anyone?
