Couple of nitpicks. First, when hydrogen reacts with oxygen to form water that's a chemical reaction, not fusion. Second, it produces energy — a problematic excess of it on that scale — you don't need energy to do it. Third, it doesn't make water from scratch, it makes it from oxygen and hydrogen.

Tatooine has oxygen (which is a problem with the science), but probably not enough to make oceans (Earth's oceans contain a thousand times as much oxygen as its atmosphere does). Tatooine does not have much hydrogen — it would need something like one hundred quadrillion tonnes of hydrogen.


But quibbles aside, Tatooine does not have large oceans and plenty of water because if it did the writers wouldn't be able to use it as a setting for stories about people on or from a desert planet.
