Otherwise, to take the data of this invention:
1.29 megajoules to scrub 1 kilo of CO2 = 3.58 kWh.
7.7cents/kWh is a recent Chinese electricity price.
$0.2757 to scrub one kilo.
EU carbon price is about $23 per tonne.
1000 x $0.2757 = $275.7 in electricity costs alone, ignoring manufacturing the devices and other overheads.
So all up, we'd need a Carbon Price of roughly $400/tonne to justify this kind of technology.
Its much easier to just keep the fossil fuels in the ground!
- canofbars 6y ago>Its much easier to just keep the fossil fuels in the ground! This is what I have seen every time carbon capture comes up. It takes an insane amount of energy to burn fuels and then unburn them. Its always better to just use the energy to not need to burn the fuel to begin with. Once we have replaced all fossil fuels then it would make sense to start unburning the stuff in the air.
