Actually, a *really* impressive fuel would be if you could make bubbles out of carbon, like big buckyballs; but stuff them full of high pressure methane. That way you'd have the hydrogen in the methane and the buckyballs would be flammable anyway. Most of the pressure would be, not in the tank, but in the walls of the buckballs. In principle, that would give you really, really good density and pretty decent ISP, and unlike liquid methane such fuel probably doesn't need to be cryogenic. I don't know whether you could make it from fullerine in hot, high pressure methane; maybe the methane would force its way inside without the buckyballs disintegrating or something. Still, buckminster fullerine is not cheap per tonne I guess, unless you could get large fullerines C100s it's probably too expensive.
