The CDR series: DIRECT AIR CAPTURE (DAC)

, 2023
In the late 1990s, the idea of directly removing CO2 from the atmosphere via large mechanical ‘filters’ first emerged. Since then, various direct air capture (DAC) concepts have been developed and several projects have been implemented worldwide.

Efficient Adsorption‐Based Direct Air Capture Via Triply Periodic Minimal Surface Architectures [PDF]

Advanced Science, EarlyView.
Architected triply periodic minimal surface (TPMS) contactors reshape direct air capture by replacing straight‐channel diffusion limits with convection‐enhanced CO2 transport. Chaotic advection thins boundary layers and exposes fast adsorption sites, enabling 70%–75% more fast sites, 114% higher productivity, and 51.8% lower energy consumption than ...

Membrane Separation Technology in Direct Air Capture

Membranes
Direct air capture (DAC) is an emerging negative CO2 emission technology that aims to introduce a feasible method for CO2 capture from the atmosphere. Unlike carbon capture from point sources, which deals with flue gas at high CO2 concentrations, carbon ...

Direct Air Capture of CO₂: Mechanism-Guided Materials, Process Integration, and Scalable Carbon Removal [PDF]

Molecules
Direct air capture of CO2 (DAC) is an emerging engineered carbon removal technology designed to extract CO2 directly from ambient air and support long-term net-negative emission pathways. Unlike point-source carbon capture, DAC operates under ultradilute

Indoor CO2 direct air capture and utilization: Key strategies towards carbon neutrality

Cleaner Engineering and Technology
Direct air capture (DAC) is a promising technology that can help to remove carbon dioxide (CO2) from the air. One application of DAC is indoor CO2 direct air capture (iCO2-DAC).

Photo-DAC: Light-Driven Ambient-Temperature Direct Air Capture by a Photobase [PDF]

Journal of the American Chemical Society
Direct air capture (DAC) may reduce atmospheric CO2 concentrations to preindustrial levels, yet the high energies and temperatures involved in current DAC technologies hinder large-scale deployment. In the case of aqueous-based CO2 absorbents, a large energetic penalty is associated with heating and boiling off water, as required for thermally driven ...

Correspondence on “The Open DAC 2023 Dataset and Challenges for Sorbent Discovery in Direct Air Capture”

ACS Central Science
This Correspondence provides a brief commentary on a recent ACS Central Science article that identifies metal-organic frameworks for direct air capture and suggests that the recommended structures are artifacts of the methodology used.

Direct Air Capture (DAC) in Germany: resource implications of a possible rollout in 2045 [PDF]

Annales des Mines - Responsabilité et environnement, 2022
Direct Air Capture (DAC) is increasingly being discussed as a possibility to limit climate change. In this study, a possible rollout of the DAC technology at German coastal areas is analysed based on an existing climate neutrality scenario.
