A new relevant membrane application: CO2 direct air capture (DAC)

Chemical Engineering Journal, 2022
Since carbon dioxide (CO2) is the primary greenhouse gas emitted into the atmosphere due to human activities, strong research efforts have been developed towards capturing and decreasing its production. Unfortunately, specific processes and activities make it impossible to avoid CO2 emissions.

Study of Direct Air Capture (DAC) Using a KOH/K2CO3 Absorbing Solution for CO2 Capture

SSRN Electronic Journal, 2022
Direct Air Capture (DAC) consists of sequestrating CO2 from ambient air using absorption or adsorption mechanisms. Within the former, alkaline solutions, such as KOH, are generally used as the absorbing agent due to the high reached pH values favouring CO2 absorption. However, these solutions' alkalinity induces high corrosivity and harmful properties,

Direct air capture (DAC) and sequestration of CO₂: Dramatic effect of coordinated Cu(II) onto a chelating weak base ion exchanger. [PDF]

Sci Adv, 2023
Direct air capture (DAC) is important for achieving net-zero greenhouse gas emissions by 2050. However, the ultradilute atmospheric CO2 concentration (~400 parts per million) poses a formidable hurdle for high CO2 capture capacities using sorption ...

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.

A review of direct air capture (DAC): scaling up commercial technologies and innovating for the future

Progress in Energy, 2021
Direct air capture (DAC) can provide an impactful, engineered approach to combat climate change by removing carbon dioxide (CO2) from the air. However, to meet climate goals, DAC needs to be scaled at a rapid rate.

A Comparative Study of Different Sorbents in the Context of Direct Air Capture (DAC): Evaluation of Key Performance Indicators and Comparisons

Applied Sciences, 2022
Direct air capture can be based on an adsorption system, and the used sorbent (chemisorbents or physisorbents) influences process. In this work, two amine-functionalized sorbents, as chemisorbents, and three different metal organic frameworks, as ...
