TLDR
A conceptually simple method for optimizing the design of a gas–liquid contactor for capture of carbon dioxide from ambient air, or ‘air capture’ is presented and it is found that the total costs for air contacting alone can be of the order of $60 per tonne CO2.Abstract:
We present a conceptually simple method for optimizing the design of a gas-liquid contactor for capture of carbon dioxide from ambient air, or 'air capture'. We apply the method to a slab geometry contactor that uses components, design and fabrication methods derived from cooling towers. We use mass transfer data appropriate for capture using a strong NaOH solution, combined with engineering and cost data derived from engineering studies performed by Carbon Engineering Ltd, and find that the total costs for air contacting alone-no regeneration-can be of the order of $60 per tonne CO(2). We analyse the reasons why our cost estimate diverges from that of other recent reports and conclude that the divergence arises from fundamental design choices rather than from differences in costing methodology. Finally, we review the technology risks and conclude that they can be readily addressed by prototype testing.read more

Direct Capture of CO2 from Ambient Air
TL;DR: It is concluded that there are many new materials that could play a role in emerging DAC technologies, however, these materials need to be further investigated and developed with a practical sorbent-air contacting process in mind if society is to make rapid progress in deploying DAC as a means of mitigating climate change.
