Wouldn't that be a good thing in general though? If we use Hydrogen as our storage format, then you can do the following: Sea Water (H2O + sea junk) -> H2 Then later when generating electricity: 2 * (H2) + O2 -> H2O (fresh) + energy Naturally, the resultant H2O can be moved and recycled. I think a catalyst that splits water points towards a potential where we have more fresh water, not less.
