-==Green hydrogen from fossil fuels?==
-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.}}
