But eventually it's hoped hydrogen will be made from water through electrolysis, which currently takes more energy than it produces.

Uhh, given the laws of nature, it will always take more energy than is produced, as long as you're dealing with chemical processes.

To get more energy from water than you put in would require a Mr. Fusion, which may be a few years down the road.

Great observation. So simple, and yet so many people don't seem to understand it. To produce 'free' (unattached) hydrogen, we need to release the chemical bonds, which will always take more energy in than the energy it puts out.

Wow - I just got a revolutionary idea, why don't we store the hydrogen in something where the energy is more easily released, and yet it is still concentrated, and storable and relatively safe. How about we add some carbon to the mix, and we could have a hydro-carbon fuel - yeah,that's it. And since it is made from hydrogen gas, we could call it what? Why how about 'gas' or 'gasoline'?

Ughh, you obviously don’t understand the laws of thermodynamics.
