Perhaps.

But count me a skeptic about the potential energy utility.

Lifting the weights inside a grandfather clock stores energy. That energy is released as the clock displays advancing time, and the weights descend.

Similarly, pulling hydrogen and oxygen apart requires energy input. And it will yield some of that energy when they're recombined.

It will never take less energy to pull hydrogen and oxygen apart than it releases when they're recombined.
