Sun et al. (2023): Recent progress on direct air capture of carbon dioxide

Jialiang Sun, Meng Zhao, Liang Huang, Tianyu Zhang, Qiang Wang IN: Current Opinion in Green and Sustainable Chemistry, 100752, https://doi.org/10.1016/j.cogsc.2023.100752

In this work, the authors systematically summarized the latest progress on the development of direct air capture and comprehensively reviewed the properties and performance of DAC adsorbents, which are categorized as physisorption and chemisorption according to sorption mechanisms.

Nature-Seo & Hatton (2023): Electrochemical direct air capture of CO2 using neutral red as reversible redox-active material

Seo, H., Hatton, T.A. IN: Nat Commun 14, 313 (2023). https://doi.org/10.1038/s41467-023-35866-w

The authors demonstrate electrochemical direct air capture using neutral red as a redox-active material in an aqueous solution enabled by the inclusion of nicotinamide as a hydrotropic solubilizing agent. The electrochemical system demonstrates a high electron utilization of 0.71 in a continuous flow cell with an estimated minimum work of 35 kJe per mole of CO2 from 15% CO2. Further exploration using ambient air (410 ppm CO2 in the presence of 20% oxygen) as a feed gas shows electron utilization of 0.38 in a continuous flow cell to provide an estimated minimum work of 65 kJe per mole of CO2.

White Paper: How Direct Air Capture Succeeds

Courtni Holness, Shuchi Talati, Eliot Reali, Tracy Yu on carbon180.org, 20 pp.

Direct air capture (DAC) hubs will soon begin to come online and set the US on a course to remove millions of tons of CO₂ — but the field currently lacks clear, shared markers of success. This white paper offers an original framework to assess progress and ensure these hubs empower innovators and communities.

Sodiq et al. (2023): A review on progress made in direct air capture of CO2

Ahmed Sodiq, Yasser Abdullatif, Brahim Aissa, Arash Ostovar, Nashaat Nassar, Muftah El-Naas, Abdulkarem Amhamed IN: Environmental Technology & Innovation 29, 102991, https://doi.org/10.1016/j.eti.2022.102991

In this work, the literature was comprehensively reviewed to assess the progress made in DAC, its associated technologies, and the advances made in the state-of-the-art. Thus, it is proposed to use traditional heating, ventilation, and air conditioning (HVAC) system (mainly the air conditioning system), as a preexisting technology, to capture CO2 directly from the atmosphere, such that the energy needed to capture is provided by the HVAC system of choice.

Su et al. (2023): Direct Air Capture of CO2 through Carbonate Alkalinity Generated by Phytoplankton Nitrate Assimilation

Jing Su, Hui Teng, Xiang Wan, Jainchao Zhang & Cong-Qiang Liu IN: Int. J. Environ. Res. Public Health 20(1), 550; https://doi.org/10.3390/ijerph20010550

Here the authors report an ocean alkalinity-based CO2 sequestration scheme, taking advantage of proton consumption during nitrate assimilation by marine photosynthetic microbes, and the ensuing enhancement of seawater CO2 absorption.

Low et al. (2022): Analytical review of the current state of knowledge of adsorption materials and processes for direct air capture

May-Yin (Ashlyn) Low, Lucy Barton, Ronny Pini, Camille Petit IN: Chemical Engineering Research and Design, https://doi.org/10.1016/j.cherd.2022.11.040

The scope of this review is to outline the advancement of adsorption-based DAC technologies, as well as to highlight the still-existing data gaps, for both materials’ development and process design in the period 2016 – 2021.

Zhao et al. (2023): An environment-friendly technique for direct air capture of carbon dioxide via a designed cellulose and calcium system

He-Xiang Zhao, Jiu-Cheng Li, Yan Wang, Yuan-Ru Guo, Shujun Li, Qing-Jiang Pan IN: Separation and Purification Technology Vol 307, https://doi.org/10.1016/j.seppur.2022.122774

By means of DAC, herein a facile method has been developed to capture CO2 with a designed system of biomass cellulose-added Ca2+ solution. The resultant calcite CaCO3 is found to be uniformly attached to the cellulose fibrils. Compared to a non-cellulose system, cellulose raises the CO2 capture efficiency by 32%.

Casaban et al. (2022): The impact of Direct Air Capture during the last two decades: A bibliometric analysis of the scientific research, part I

Daniel Casaban, Sean Ritchie, Elena Tsalaporta IN: Sustainable Chemistry for Climate Action, Vol 1, https://doi.org/10.1016/j.scca.2022.100009

In the past, the vast investment in renewable technology is allowing today’s rapid deployment. Why is this not currently happening in the CO2 capture area? This bibliometric analysis which focused on the use of solid sorbents in the CO2 capture field between 2001 and 2021, aims to answer these questions. The study reviewed three capture methods: post-combustion, pre-combustion and DAC, with particular emphasis on the latter.

Science-Evans et al. (2022): Aluminum formate, Al(HCOO)3: An earth-abundant, scalable, and highly selective material for CO2 capture

Hayden A. Evans, Dinesh Mullangi, Zeyu Deng, Yuxiang Wang, Shing Bo Peh, Fengxia Wei, John Wang, Craig M. Brown, Dan Zhao, Pieremanuele Canepa, Anthony K. Cheetham IN: Science Advances Vol 8 (44), DOI: 10.1126/sciadv.ade1473

A combination of gas adsorption and gas breakthrough measurements show that the metal-organic framework, Al(HCOO)3 (ALF), which can be made inexpensively from commodity chemicals, exhibits excellent CO2 adsorption capacities and outstanding CO2/N2 selectivity that enable it to remove CO2 from dried CO2-containing gas streams at elevated temperatures (323 kelvin).
