This sounds interesting. Not real clear about details, but apparently it uses silicotungstic acid, a common oxidative catalyst. Water electrolysis produces oxygen, which would be catalytically oxidized to peroxide, binding O-, and presumably the H+ is bound somehow as well. Later hydrogen (as H-H) and oxygen are recoverable without further energy input, much as oxygen is released from hydrogen peroxide because it's already at a higher energy state. That's as much as I can glean from the paper's abstract. Perhaps some folks out there can read between the lines better than I'm able to. I gather the utility of the technology is not so much for high demand applications, like electric cars, but more for large scale electricity generation, replacing (or augmenting) current fossil-fuel sources feeding the electric power grid.
