The aluminium is the fuel, the gallium the catalyst:
Al + 3 H2O --gallium or mercury--> Al(OH)3 + 1 1/2 H2
Aluminium is a fuel we manufacture from its oxidized state by electrolysis, exactly like hydrogen. But Aluminium electrolysis is far less efficient.
Aluminium metal is a wonderful storage medium for energy, a mole of electrons as aluminium weighs just nine grams, but this process is endothermic - uses more energy than it delivers - far worse even than hydrogen itself.
What we need is PRIMARY ENERGY. Processes that yield far more energy than it costs. On the longer term, the biggest players would be space-based solar and Deuterium fusion, both exploiting thermonuclear reactions.
Fusion or bust.

Well, thats not strictly true.
How else are you going to make it? Fossil Fuels? There is not repository of free hydrogen we can tap on earth. To make it we need energy from some other source, period.
Perhaps you think little green men will give us hydrogen?
Quit being you asked me what it has to do with hydrogen, I explained it. No need to get all butt-hurt and offensive.
Anyway, there ARE other ways of making hydrogen. There are chemical and biological methods.
The other week I was reading on the science forum here that they are developing new chemical methods which are looking to be extremely efficient.
I read through your replies but seems you are just spouting rubbish out in some ego frenzy to prove to yourself that you are correct.
Try listening to other people here, conversation is a 2 way thing. You are not conversing.

Let me do the work for you eh?

Heres the article.
Now go argue with the scientists who are researching this. My trust certainly lays with them over your assertive opinions.

Thats good. You see the key difference between this research and the research on the alloy right? These scientists are researching a new energy 'source'. The ones researching the aluminum gallium are only researching a way to 'store' energy. The energy must still be had from somewhere else, and as Wiccan pointed out, storing energy in aluminum is less efficient than in hydrogen itself.

I feel I should contribute to this. I've been VERY active in the solar/alternative vehicle arena for the past 15 years. Wiccan is right...clean nuclear power is the most likely immediate answer. As far as vehicles go, the energy density of hydrogen, even adsorbed onto metal hydrides or compressed to liquid, is nothing compared to gasoline.
I've worked with silicon solar cells that have broken 30% efficiency, and when they get cheap (they will), they could be used as a roofing material. This could be used to charge lithium chemistry batteries or, possibly, flywheels/kinetic storage devices. A hydrogen economy is unlikely, but if it does work the hydrogen storage won't be on vehicles. Trust me, I'm all for it, but I think batteries will be the main in-vehicle energy storage device for quite awhile.
