Scientists has found a way to electrolyze water in two steps, rather than splitting the "H2" and the "O" at the same time. If you can keep a type of high-H2 water liquid at room temps and room pressures, it opens the way to very dense H2 production as a mobile fuel.
I don't know if this is vapor-ware, or something that is "possible" but also very far off, but...it sounds interesting. They didn't mention the efficiency of energy in:H2-out, so...if it works at all, it may be as a fuel cell feedstock produced by wind or solar-PV when there is an excess, to store energy for use during low wind/sun times...
