9. Only if the energy hydrolyzing the water is green.

And let's make sure that everybody understands that there are no sources of hydrogen on Earth, except that like in water, H2O.

And let's make sure that everybody understands that it takes more energy to free the hydrogen from water than burning the hydrogen generates. It's that nasty physics poking it's ugly head again.

S = k Log W

Thermodynamics is a bitch.

Hydrogen is not an energy source and anybody who says it is, is lying.

But it might be a good energy storage mechanism, if it can be done efficiently. This OP may be a way to lead to that goal.
