Hydrogen is not itself a source of energy. (The same can be said of both electricity and batteries)

- vonklaus 12y agoWhile electricity is "not a source of energy", it does have the two fold benefit of being continuously generated, ans having widely available infrastructure. Hydrogen, while being 91% present in the universe, has only trace amount naturally occuring on earth. So to get it we can chop is off methane (a fossil fuel and already great energy store in it's own right), blast h20 with electricity (which could be fed directly into batteries with minimal loss) or biomass fermentation. http://www.afdc.energy.gov/fuels/hydrogen_production.html http://www.afdc.energy.gov/fuels/hydrogen_production.html When you couple the lack of availability, lack of infrastructure, and inefficiency of production, you are left with a tiny element that is difficult to store and extremely combustable. It just doesn't make sense vs electricity and batteries.

- mikeash 12y agoThe difference is that everybody knows that's true of electricity (a shocking number of people think that hydrogen is just somehow... found), electricity infrastructure is way better developed, and electrical generation is considerably more efficient.
