“I don’t believe that equation is applicable to electrolysis.”

It is.

It is, but, the energy works the other way, where it takes energy to split the water molecule, thereby consuming energy to produce the hydrogen; iow, the action uses energy rather than producing energy (though there is an insignificant amount of energy produced by the splitting of the water molecule

If hydrogen was readily available, there would be no need to use the energy to produce electrolysis, but as it stands electrolysis requires the use of energy.

Chemical bonds are much weaker than nuclear bonds.

The amount of energy to chemically separate hydrogen is very small compared to the energy gained in fusion.
