because there isn't any.
you can drill a hole in the ground and find natural gas.
you cannot drill a hole in the ground and find hydrogen.
it doesn't exist naturally on, or near, the surface of the earth, in any significant quantity.
and by the time you've gone to the effort of creating it, you've wasted far more energy than the hydrogen you created contains.

You can convert gross calorific value (GCV) to net calorific value (NCV) by subtracting the latent heat of vaporization of water formed during combustion from GCV. The equation for this is NCV = GCV - 2.5 x (9 x % H2 - % O2), where % H2 is the percentage of hydrogen in the fuel and % O2 is the percentage of oxygen in the fuel.
Hydrogen has the highest calorific value, which should make it good fuel
