Do you mean why don't we extract hydrogen from water to use as fuel?
The simple answer is that the energy used to electrolyze water is equal or greater (no process is perfectly efficient) than the energy you get from burning the hydrogen or using it in a fuel cell.
One idea is to use solar "farms" in desert areas to electrolyze hydrogen out of water, then transport the hydrogen elsewhere for use, perhaps as a vehicle fuel. Might or might not be more practical to simply produce electricity.

As far as I know there is only one way to extract hydrogen from water and that is electrolysis.
