As I have stated before, delivering hydrogen straight to fuel cells, where the cells in question are distributed as closely to every point of useage as possible, would eliminate the need for transmission wires to a very significant degree. After all, we're going to need to keep roads and highways going, as a transport channel, for a good deal of time to come into the future. And that's not such a bad thing considering that those channels have a good deal of multipurpose usage going for them (especially if we could always include pipe lines within the same right of ways as much as possible). The same, however, cannot be said of high tension power lines, and all of the poles, towers, and ancillary equipment required to keep them functional.
This ought to be a no brainer, but because Big Money has already put so much investment into big, centralized, dirty fuel (to varying degrees) plants, of course, getting power distribution into the era of distributed processing has been thwarted. Just one in a long list of things that Big Money is good at thwarting.
