Show me a source of H2 that you can get without pouring energy into separating it from another compound, or leaving Earth.
You can't.
It's not a fuel, it's an energy storage medium.
No, it is a fuel, as well as an energy storage medium, just like a hydrocarbon. You need an oxidizer to liberate the energy.
FYI, the whole rocket community refers to it as a fuel.
Furthermore, I never said that you could extract hydrogen without using energy.
