Now if the hydrogen were produced by solar/wind it would be good.

Good thinking me boy. But do you know how much energy it takes to
crack
it?

Electrolysis me boy.
water into hydrogen and oxygen.

That is the process. I said "do you know how much energy it takes to
crack
it?"

Not much.
9V DC will do it (you can try with a pp3 battery if you like).

If that is the case then we would be cracking water at point use, like in
an
engine bay, and using it to drives cars and heat our homes. Strange in
that
is not the case.

The fact is that the energy to crack it is more than what useful energy
you
get from hydrogen.

That is the holy grail, to cheaply crack hydrogen, once that is solved
then
the enrgy crisis os over for good.

Try again.

You don't do chemistry do you?
The energy required to separate hydrogen from oxygen in water is quite low.
As I stated a 9v battery is enough.
You get less useful energy back when you recombine it to make water and
energy.

To use it to power cars you don't need any more energy to split the bonds
but you need lots of power to get the volume of hydrogen needed for a days
driving.
A few nuclear power plants splitting hydrogen would seem a good idea at this
time.
I doubt if anyone will do so in the near future.

Is that simple enough for you?
