With all of the talk and focus on direct air capture, it seems like core issue of capturing CO2 at its pollution sources (esp coal and natural gas power plants) is getting less and less attention.
This comment by Ron Socolow sums it up very well- "We should be suspicious of distractions, and, to my mind, direct air capture is one of these. Air capture is a close neighbor of post-combustion capture at coal and gas power plants, a much cheaper mitigation strategy. This simple fact about technological neighbors tells is to be very careful always to state that near the top of the mitigation agenda for several decades is decarbonizing the global power system. There is something grotesque about pulling CO2 our of the air at one place while pouring it into the air at four-hundred times greater concentration at another place. First things first." Considering CO2 is 400 times more concentrated at the pollution sources, shouldn't most of the focus be placed on new and innovative ways to capture this? Have any such solutions been presented here or outside of this group? Thanks- Mark -- You received this message because you are subscribed to the Google Groups "geoengineering" group.
