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.


Funding novel research towards atmospheric CO2 removal

Tue, 28 February 2023, 16:00 – 17:00 GMT; by Carbon Technology Research Foundation (CTRF)

CTRF’s inaugural call for research proposals will be launched by the Director of Research, Dr Sarah Wagstaffe-Jones. In 2023, they will be offering up to £4M in anticipation of funding 4-7 projects. During the session, CTRF’s initial priority areas for funding will be communicated and guidance on the application and peer review processes which will be adopted by CTRF will be provided. This webinar will be of particular interest to researchers working within the CDR space, or those wishing to pivot their innovative programmes and methodologies towards the sector. We would also encourage policymakers, funders and investors to join in the discussion.


Doctoral Research Assistant (m/f/d)

Deadline: 19th February 2023

The Department of Applied Ecology (Professorship for Research into Climate Impacts) in Geisenheim in the Rheingau region (50 km west of Frankfurt/Main) is seeking a doctoral research assistant on part-time basis (65%) for the period of three years.

In a joint project on strategies for CO 2 removal from the atmosphere, researchers from Geisenheim University (HGU), the University of Hamburg, the Potsdam Institute for Climate Impact Research and the Ithaka Institute will explore synergies of combining two methods of „carbondioxide removal“ (CDR) – the use of biochar and rock flour in agriculture. The candidate on the HGU side applies methods of crop science (soil science, plant nutrition), greenhouse gas flux measurements, and uses stable isotopes ( 13C-CO 2) to quantify C input and fate in soils.


CO2-Speicherung bleibt im Landtag umstritten

ZEIT Online, 27. Januar 2023, 16:53 Uhr; dpa Hamburg/Schleswig-Holstein

„Die unterirdische Speicherung von Kohlendioxid rückt in Schleswig-Holstein in den Fokus des Landtags. Mit den Stimmen von CDU und Grünen beschloss das Parlament am Freitag eine Expertenanhörung. Zuvor hatte Ministerpräsident Daniel Günther (CDU) betont, die Technik CCS sei gut beherrschbar und die Risiken seien lokal begrenzt. Ein Einlagern von CO2 an Land und innerhalb der 12-Meilen-Zone schloss er aus.“


Washington Post: Carbon Removal Is Where Green Investment Should Go

by Lara Williams (Bloomberg) on washingtonpost.com, January 27, 2023 at 10:49

„Green investment hit a milestone in 2022: The world put as much money into replacing fossil fuels as it put into producing them, with clean energy investments jumping 31% from 2021 to top $1 trillion for the first time. Of course, it’s not job done. Annual investments into decarbonizing the economy must triple for the rest of this decade. One area that’s seen a dramatic expansion in investment lately is carbon capture.“

Scrubbing the Skies: Wood Harvesting and Storage with Wood Vault for Durable Carbon Sequestration: Scientific Needs and Societal Impacts

Thu, February 9, 2023, 1:00 PM – 2:00 PM EST; hosted by Institute for Carbon Removal Law and Policy

Wood Harvesting and Storage (WHS) is a novel hybrid Nature-engineering method for carbon dioxide removal (CDR) and semi-permanent sequestration. In this method, sustainably sourced woody biomass is buried in Wood Vault, an engineering structure designed to maintain anaerobic conditions to prevent wood decomposition. Participants will discuss the carbon sequestration potential of this approach, as well as critical questions related to monitoring and verification, and the challenges of full-carbon accounting.
