Who says the fossil fuel carbon will be captured? It's certainly not now and who says carbon capture is ever going to be enforced?
The only hope I have is that solar energy becomes so cheap that it can be profitably used to produce synfuel and so drive petroleum from the market. Actual regulation would be better but that seems as far as ever.
Who says solar energy can possibly get that cheap?
If you are skeptical of carbon capture being mandated by regulations then I think you should be equally if not more skeptical of the market restructuring itself so renewable energy based petroleum substitution becomes a reality spontaneously. It makes no sense economically or politically.
