Is it thermodynamically possible to ''extract'' the hydrogen from fossil fuel molecules while leaving behind solid carbon (not oxidized to CO2)?


Example chemical formula: CH4 -> 2 H2 + C<br />
Of course this is only worthwhile if it takes less energy than you would get from burning the H2 later.
If it is viable, maybe we could get all our energy from fossil fuels and just "burn the hydrogen, not the carbon"?
I have read about so-called ''blue hydrogen'' {{x|At first, I thought it was this same idea - but then I read it's basically just conventional hydrogen production with some added [[carbon capture]], and not much greener overall. I'll try to find the original citation again.}}
