The $3.00/gallon price doesn't pass the sniff test, please tell me what I'm missing:
1 gallon of gas is 33kwh of energy
1 kwh of electricity, wholesale in the US, is approx 3-8 cents or higher, so 1.65-4.4$/GEG of electricity
CO2 to gas process efficiency electrochemical would be optimistic at 60%
CO2 sequestration from air costs 40-120$/tonne, optimistically estimated from not-yet industrially available technology.
That scales by approximately 44/14 or 3x (weight CO2 to CH2) so 120-360$/tonne gasoline. At approx 2.8kg/gal (350 gal/tonne) that is an additional 0.34-1.02$/gal.
So before research amortization, capital, operations, maintenance, transport, and profit I'm seeing an optimistic best-case of a >2$/GEG production cost.
This is of course assuming they can actually do what they are claiming. And that they can do it at scale, at meaningful throughput, and with process stability.
