The application I wish I could figure out how to make work is hydrogen storage. But even concentrated H3O requires electrons to become H2 + H2O.
If you're thinking about storing power, an iron based flow battery like the one in the YT in the last post is supposedly good to about 25wh per liter of water. Not much but it's just water and iron which are extremely cheap. And that amounts to 25kwh per cubic meter of water... not at all bad.
An olympic sized swimming pool of 2-3 meter depth is about 3000 cubic meters, so if you have two of those full of iron water slurry, that's 75MWh of storage.
Maybe I'll do a future energy post on cheap flow batteries...
