Expensive inlet contactor and poor absortive solution

An air–liquid contactor for large-scale capture of CO2 from air

Average estimate - 100 $; doesnt include costs
of capital expenditures for constructing and/or maintaining
equipment; adsorption-based air capture technology: amino-modified silica adsorbent, TRI-PE-MCM-41, and a structured monolithic contactor unit

Analysis of Equilibrium-Based TSA Processes for Direct Capture of CO2 from Air

Five-step temperature vacuum swing adsorption process for direct air capture using solid adsorbents coated
as films on monolithic contactors using steam as the stripping agent during desorption, using MIL-101(Cr)- PEI-800 as a metal organic framework

Does not account for cost reduction associated with the experience curve, nor the effect of economies of scale

The potential for implementation of Negative Emission Technologies in Scotland

Argues that energetic and financial costs of capturing CO2 from the air are likely to have been underestimated in other studies

Economic and energetic analysis of capturing CO2 from ambient air

An optimal combination
with an onsite NGCC (natural gas combined cycle) facility with CCS (cabon capture and storage) combined with
heat integration and the use of plastic packing in the towers

Reducing the Cost of Ca-Based Direct Air Capture of CO2

Worst case scenario: adsorbent
with the shortest lifetime and the most expensive synthesis, lowest
swing fraction during the adsorption–desorption step and the
highest H2O:CO2 ratio

Solid sorbents such as metal organic frameworks (MOFs), contained in
low pressure drop contactors; mid range estimate: 86$-221$. The mid-range analysis assumes adsorbent purchase cost and lifetime
of $50/kg and 0.5 years, respectively, sorbent total capacity of
1 mol/kg, desorption swing capacity as 80% of SCmax
desorption pressure and temperature as 0.5 bar and 360 K, respectively,
contactor to adsorbent ratio in the range of 0.1:1 to 1:1
and CO2 to water ratio as 1:2.

A parametric study of the technoeconomics of Direct CO2 Air Capture (DAC) systems using solid adsorbents

They compare to APS report and note price differences due primarily to new Contactor technologz designed by Carbon Engineering.and use of K+ rather than Na+. They use Hydroxide sorbent in contactor and Ca in pellet reactor.
