It will take approx. 60 kWh/gallon of fuel, or just under 16 kWh/Liter. As long as this electricity is from zero carbon sources and is inexpensive enough, it works. Distillation and other thermal processes typically need to burn fossil fuels. The difference between renewable electrical energy only vs using thermal is really more a difference of kind than of degree. It's really hard to do a thermal process that is truly zero carbon, and hard to do it economically as well.
- JudgeWapner 7y agohow much energy is spent pulling CO2 out of the air? I know this sounds like a step backward, but perhaps burning plant matter or recycled cardboard might be a more efficient source of CO2? If purifying smoke is cheaper (energy-wise), maybe you could let mother nature extract the CO2 through fast-growing plants, then dry and burn them?
