It can be very useful for energy storage and keeping existing combustion plant usable. But the op does not seem to bear in mind the fact that it requires more energy input than it outputs in the form of a carbon neutral fuel, or that renewable technologies have by this date clearly demonstrated affordable solutions to carbon neutral power generation.
- Gibbon1 7y agoWhen I read about these schemes to produce gasoline from CO2 and water or whatever I can't help but think someone needs a couple of semesters of thermodynamics beat into them.
- DennisP 7y agoNobody thinks they'll get net energy out of this. They're spending energy to make carbon-neutral liquid fuels. The energy would have to come from renewables or nuclear for this to be useful.
- Gibbon1 7y agoThe energy return on energy invested is going to be abysmal. No more than 20% if that. That translates into synth gasoline at $30/gallon
- ip26 7y agoConsidering electric planes aren't feasible yet, how else do you plan to decarbonize airplanes?
- strainer 7y agoShort range electric planes are being manufactured presently. This wont be able to decarbonize anything until surplus carbon free energy is generated for it use - that need not take decades with proper governmental policies, but it means this technology will not lead the way.
- D_Alex 7y agoReplace, as far as practicable, with fast trains and maybe Hyperloops.
- aaronblohowiak 7y agoHow do you figure?
- Gibbon1 7y agoEstimate the cost of the energy inputs per gallon of gasoline. Account for the inefficiency and you get $15-20/gal.
