Well there is some mental jacking off here Duke Leto, but here is an example of hydrogenated pyrolysis production (like I have been saying), actually its hydrogenated gasification but the inputs and outputs are the same.

So its is in fact being looked at, the only problem is the need for energy to make hydrogen, in this case its assumed solar or nuclear power providesthe energy, and I would put my bets on solar as it is now.
