Argonne has a short paper out outlining a “green” energy solution that looks more plausible than any I’ve seen for a while. If you take “carbon” seriously (I don’t but I’m in something of a minority on that) you should read this. If you don’t, however, and do take peak oil or oil independence seriously then you should still read it.
For Green Freedom the basic idea is that you take a nuclear power plant for its supply of electricity and steam. With that you use a potassium/carbon compound CO2 + water + hydrogen via electrolysis to combine in a process that produces methanol which is then in turn further processed to a synthetic gasoline. Basically the nuclear reaction/energy drives a reaction reclaiming carbon and O2 from the air to form that gas, which is then burned in cars re-releasing that carbon back to the atmosphere in a completely carbon neutral process. It is not of course energy/lite, but that isn’t the point here.
The paper suggests some economics, but basically a price point for gasoline right about where it is now, makes installation of new plants feasible.
