One thing that I think is overlooked in this thread (though I didn’t read it all) is that carbon capture/sequestration is not incompatible with burning fossil fuels. You get the energy by breaking bonds of (somewhat) complex hydrocarbons, but it takes less energy than is released to capture/sequester the resulting carbon (at least theoretically/for some methods). Therefore there is a possible future where energy could come from fossil fuels without CO2 release. There are other reasons one may not want energy from fossil fuels, however.
