I agree flywheels are not worth pursuing.  Years ago articles touted their virtues, but today I see none.  Thanks for your comments.

Natural-gas fuel cells
Jon Titus   3/7/2012 5:49:48 PM
NO RATINGS
Not to worry about hydrogen, Alex.  A fuel cell based on methane--already available as natural gas--would do the trick and we already have a distribution network in place.  I believe some materials such as activated carbon and perhaps carbon nanotubes readily absorb methane, so need for high-pressure storage tanks or cryogenic delivery of liquid hydrogen. Flue cerlls run hot, though, so we still must content with high temps, which can limit use in vehicles.
