I think most people talking about hydrogen economies envisage some scheme for producing hydrogen using sunlight, perhaps by using some helpful organism that can do this. The hydrogen itself would be a useful way to store energy for use in vehicles or to transport it around for use in fixed sites. I suppose this is really how the hydrocarbon economy works, just with a much larger gap between the storage of solar energy in chemical form and its eventual release. I think that when we eventually get to the stage of colonising other star systems, we'll do the same with antimatter, producing it here in the Solar System using fusion or solar power and taking advantage of its its extremely high release of energy per unit mass to achieve much better starship performance than we can manage in fusion-powered ships.
