The fundamental problem with carbon capture is that 1) carbon comprises a tiny fraction of Air, and 2) requires energy input in some form. This means whatever methodology you use, will require you to expand energy to move huge volumes of air to remove a small number of particles (i.e. ~400 particles of Carbon, for 1 million Air particles).
- hedora 4y agoAlthough this is a big problem, air tends to mix itself. Most solutions that are being commercialized are targeting $100/ton at scale. Due to convenient unit conversions, this translates to $1.00/gallon of gasoline burned. This tells us a few things about the energy efficiency of those processes, but, as importantly, they would be economically viable in that price range. (A $1/gallon gas tax would have much less economic impact than the war in Ukraine, or prior wars in the Middle East.)
