In order to get the energy back out of it you convert it back into water, or if you leave it alone it will do it itself in the atmosphere, if you want to be afraid of loosing a gas, be sad for helium. It mostly non-reactive and too light for our atmosphere, all those helium balloons of the world are loosing helium to space, with little to no replenishment, and none that's effectively used.
