Can you use any kind of water? Or filtered and treated special water? The article says that we can use the "most abundant substance on earth", which would be the case if we can use sea water straight from the ocean. If it is the case, that'd be amazing.

This sounds too good to be true so what's the catch? I'm all for advances towards being independent of oil, but I don't see the draw back here. What's holding this back from mass production and adoption?
