    How do you mean? Water in motion generate3s energy in wave plants and hydro plants for example.

    Hydroelectric energy is just the kinetic energy of moving water. I think scientist.v is asking if there is any energy “locked up” in H<sub>2</sub>O itself that we can extract.

    you could add water to a reactant which
    releases heat in an exothermic process.

    calcium oxide, CaO + water is a highly exothermic process

    but im not sure on the economics of the process to see if it is viable
    everything is mathematical.

    Well C<sub>a</sub>O is created by burning C<sub>a</sub>O<sub>3</sub> which requires energy, so that process doesn't give you anything.
    Of course you could get energy out of water, theoretically, by using it in fusion reactors (which unfortunately , as I assume you know, do not exist).

    Actually, energy of sunlight can be used to split water into dioxygen and hydrogen gas. Modified titanium dioxide catalyst is needed. Unfortunately, only some wave lenghts of sunlight give this effect. For now, of course.
