I think our best way right now to get power from hydrogen is by burning oil, coal and natural gas. Their concentrated hydrogen content is what gives them energy in the 1st place. What causes the problems is the actual hydrocarbon.
Running a vehicle on hydrogen without using carbon involves using either hydrogen fuel cells or ordinary engines modified to burn hydrogen.
If you really look at it, this technology isn't really new. Over 100 years ago, the fuel cells combined hydrogen and oxygen, producing heat and water, the heat was used to create electricity, and the water was like a waste product. As in ethanol, fuel cells are still kind of pricey though.
Maybe engineers can retool a vehicle's engine to run on hydrogen. I'm not sure how expensive or complicated this would be though.

All I know is I have heard of the Hindenberg blimp and the way folks drive these days, I would be freaked out if there H2 fuel cells in them...
Well, there are several bonds that when broken will give several levels of energy. From what I remember from chem, is that H2O is an ionic bond with dipole moments on the oxygen. It is H-O--H that has resonance from one H to the other. When protonation occurs due to stronger ions, like salt, the furthest H+ or proton will leave. The only other way to break that bond is through a radical formation either by HOOH or HO(.) or a straight nuclide attack (fission). That is how I understand it, and I could be wrong...
When we use H2CCHOH, in a combustible system, because the m.p. is lower, even due to some level of evaporation, we burn steam. But the octane in gas is what gives us the power generation to put through the cylinders in the engine. Other oil products, besides gas, will still need to be used, such as motor oil, transmission, brake fluid, coolant, etc. Coolant is something else, I think--Polyethylene Glycol (PEG) they smart chemists have probably changed it now...
