Icelandic Direct Air Capture:
A Chilean paper discussing the chemical absorption (amine based) and alternative for CO2 capture:
One thing that seemed interesting to me about the chilean paper was that it talked about how direct capture wasn't feasible because atmospheric concentrations of CO2 were too low and that the air needed a lot of processing before the CO2 could be efficiently removed. But, it got me thinking about power plants. How, if you took the direct exhaust from burning fuel into the carbon capture process then maybe it could efficiently capture enough of the CO2 to make the power plant more efficient (as far as CO2 emissions per MegaWatt of energy produced).
It sound like the gas / oil companies are already thinking about this.... or at least their marketing people are!
Nature has a wonderful process for capturing CO2. I wonder how much it would cost to grow peat moss or algae or other such crappy plants and then compact / store this carbon? Effectively use the natural process of plant growth and then sequester that captured stored CO2. It's probably not economically feasible. Plus it probably produces a lot of methane and other gases as well. But, it would be nice if there was a way to use nature to help us reduce CO2 concentrations.
