Jeff Raven: Just because it takes energy to create hydrogen doesn't mean it isn't useful. How much energy goes into making alkaline batteries? They're still used, aren't they? Just because we don't "create" oil doesn't mean that we shouldn't have to create any other form of energy storage. Yes, energy is needed to get hydrogen, this is what you pay for when you buy hydrogen, a convenient form of energy storage.
Could someone edit that post which screwed up the thread?

Gurgeh, I know. My point is that it takes more energy to create and store the hydrogen, than you get out of burning it.

Jeff: The fact that it takes more energy to create Hydrogen than you get out isn't prohibitive. Most processes cause wastage of energy in some form or another. Power stations lose energy in heat, not all the energy goes into electricity ( I think most have an efficiency ~50%). My point is that it is acceptable to use it even if it causes some waste of energy, simply because of it's convenience. It's done all the time.
