it requires too much energy to break up the H2 from O
you put out fires with H20 since it does not burn but in a very high heat fire it just evaporates and does not put out fires

The simple answer is, water doesn't burn.
There are some interesting schemes out there which involve splitting water on-board and using the newly made hydrogen as fuel. I'm not a big fan of this approach, but it's out there. You still need lots of batteries on board to make this work.

Substitute for what?
The purpose of a traditional "fuel" is to produce usable energy in the form of heat or motion.
For water to achieve that purpose, the hydrogen and oxygen must be separated into gases that will burn.

The reasons for this may include :
- Water does not burn in presence of air.
- Water requires energy to get converted into steam which can be utilised.
- The electrolysis of water to generate hydrogen and oxygen is not easy.
-Being very good wetting agent it wets the surface of the metals resulting in less chances of combustion.
However it can be utilised as a source for generating hydro electric power through turbines.

Because water and what? (oxygen?) do not burn to release energy.
It takes energy to break water apart.
