I was just confused. "Hydrogen out of gas"? Well Hydrogen is a gas so that's a little confusing.
I ment this one:
http://en.wikipedia.org/wiki/Natural_gas ; lots of hydrogen in it.
And why I doubt the article ... I'll give it a quick shot, using basic knowledge of chemistry:
No matter how people do it, to get H out water you need to break the H-O bounds, and that requires a lot of energy. (I'll go out from a ideal and impossible 100% efficient methode to break it. That's better than whatever the article possible can be.) You gain the energy back when you create the H-O bounds again, but as with everything, you lose energy in the process (as heat for example). Even this way:
http://en.wikipedia.org/wiki/Fuel_cell , you'll lose quite a bit and it's more efficient than burning the hydrogen. There's just no way energy can be gained as described in the article. To gain energy, you'll have to use the hydrogen for fusion. But that's not buring, it isn't a chemical reaction to start with.
On the side, but on topic: One of the reasons petroleum is so awesome, is because it's childs play to get energy from it. The C-H bounds are relative easy to break by burning it (burn means recombine with O), creating H-O and C=O, especially C=O gives a lot of energy in the creation, and requires exactly the same amount of energy to break it. That's why CO

It's also why photosynthesis is so awesome. And why hydrogen alone isn't going to make your car drive like it's doing with petroleum products. Hydrogen alone can't hold as much energy as your fuel made by distillation of petroleum. Even our body likes to make CO[span style=\'font-size:8pt;line-height:100%\']2 to power itself. (and hydrogen definitely can't be used to make many of the synthetic materials comming from pertoleum, finding another energy source is just one of the problems we face)
Feel free to kill me if you can point out a real error in my thinking here.
