Yes Trail, This is not Competition to TP once all costs and consequences are taken into account.
I imagine the maintenance/construction costs of these "CO2 Catchers" ALONE would end up at over $130/Ton of CO2 (or $36/Ton of Carbon)
Here's more on this;
Capturing CO2 from ambient air: a feasibility assessment, Thesis by
Joshuah K. Stolaroff
Abstract
In order to mitigate climate change, deep reductions in CO2 emissions will be required in the coming
decades. Carbon capture and storage will likely play an important role in these reductions. As a compliment
to capturing CO2 from point sources, CO2 can be captured from ambient air (“air capture”), offsetting
emissions from distributed sources or reducing atmospheric concentrations when emissions have already
been constrained. In this thesis, we show that CO2 capture from air is physically and thermodynamically
feasible, discuss the various routes available, and explain why NaOH solution is a viable sorbent for largescale
capture. An example system using NaOH spray is presented. With experimental data and a variety
of numerical techniques, the use of NaOH spray for air capture is assessed and an example contacting
system developed. The cost and energy requirements of the example contacting system are estimated.
Contactor estimates are combined with estimates from industry and other research to estimate the cost of
a complete air capture system. We find that the cost of capturing CO2 with the complete system would
fall between 80 and 250 $/t-CO2, and improvements are suggested which reduce the upper-bound cost to
130 $/t-CO2. Even at the high calculated cost, air capture has implications for climate policy, however
dedicated engineering and technological innovation have potential to produce much lower-cost systems.
