Strictly speaking, energy is stored not only in molecular movements and vibrations but also in the transition between physical states. During evaporation and condensation, water absorbs and releases a relatively large amount of energy owing to the strong hydrogen bridge bonds.
Information and ideas:
As background for the topic "water as a means of energy storage" and "water in power generation", which is also important for thermal power engines, such as the steam engine. Even without going into thermodynamics, it is clear where steam engines get their energy from: The superheated steam contains a great deal of energy. Given the same volume, this corresponds to a high pressure that can move a piston.
