This is called thermal depolymerization. I have some refs and quotes about in Chapter 13 of the book. With present day technology this costs more than natural oil, and it takes a lot of energy. However, it is a useful technology because it also gets rid of waste. Perhaps it will become more cost-effective in the future. If oil is only used for jet fuel and chemical feedstock, that would eliminate ~78% of demand, making oil and jet fuel dirt cheap. By the way, improved batteries for automobiles would be much more efficient than most hydrogen production pathways (except natural gas conversion).
