Zuraiqi et al. (2022): Direct conversion of CO2 to solid carbon by Ga-based liquid metals

Karma Zuraiqi, Ali Zavabeti, Jonathan Clarke-Hannaford, Billy James Murdoch, Kalpit Shah, Michelle J. S. Spencer, Chris F. McConville, Torben Daeneke, Ken Chiang IN: Energy & Environmental Science, 2022; DOI: 10.1039/d1ee03283f

The authors report a robust and highly selective method for the direct conversion of CO2 to solid carbon over EGaIn liquid metal (LM) alloy. They concluded that the presented method creates a pathway to transforming CO2 to perpetually stored solid carbon and can therefore set a trajectory for making a measurable impact on carbon intensive industries.

UK Request for Proposals On Emerging Climate Technology Projects

Deadline: 15 April 2022, informational webinar: on 1 February 2022

At the 2021 Global Investment Summit, Prime Minister Boris Johnson and Bill Gates, the Founder of Breakthrough Energy, announced a new partnership to mobilize public and private funding in emerging climate technology projects located in the United Kingdom. The RFP is expected to remain open for submissions until 31 December 2027 (RFP close date) or until all Catalyst funds are fully committed. All respondents seeking funding in the first half of 2023 must provide their Part I Submission by 15 April 2022.

Catalyst invites responses from projects located in the United Kingdom across the following four technology sectors:

  • Clean hydrogen
  • Direct air capture
  • Long duration energy storage
  • Sustainable aviation fuel

Carbon-Negative Hydrogen from Wood Waste — Mote

Tue, January 25, 2022 6:00 PM – 7:00 PM CET

by „This is CDR„

They welcome Mac Kennedy and Josh Stolaroff from Mote to present the company’s wood waste to carbon negative hydrogen CDR pathway, which was recently funded by investors and will be opening a 150KtCO2/yr demonstration plant in Bakersfield CA in 2024.

Ortiz et al. (2022): Artificial Upwelling in Singular and Recurring Mode: Consequences for Net Community Production and Metabolic Balance

Joaquin Ortiz, Javier Arístegui, Jan Taucher, Ulf Riebesell IN: Frontiers in Marine Science 8, 2022, DOI: 10.3389/fmars.2021.743105

Artificial upwelling of nutrient-rich waters and the corresponding boost in primary productivity harbor the potential to enhance marine fishery yields and strengthen the biological pump for sequestration of atmospheric CO2. The authors conducted a large-scale off-shore mesocosm study (∼44 m3) in the oligotrophic waters of the Canary Islands to identify the community-level effects of artificial upwelling on a natural oligotrophic plankton community.

C2G Webinar: How does the Working Group-I report of the IPCC Sixth Assessment address Carbon Dioxide Removal and Solar Radiation Modification?

January, 20, 2022 03:30 PM (UTC)

This C2GLearn webinar aims to provide audiences with expert overviews of how the IPCC AR6 Working Group-I report addresses CDR and SRM, followed by a moderated Q&A session enabling the audience to ask clarifying questions and learn more. Speakers’ presentations will be pre-recorded and played to the webinar audience, with the speakers joining for the live Q&A session. Once this event reaches full capacity and you are unable to register please use this link https://youtu.be/Wezt-QIylXA to watch the YouTube livestream on the day.

Tunc et al. (2022): Direct air capture system: a feasibility study for Izmir

K.M. Murat Tunc, Levon Cagla, Mustafa Kasikci, Rafet Yagiz Caliskan, Zeynep Korkmaz IN: International Journal of Sustainable Energy, DOI: 10.1080/14786451.2021.2024831

This study aims to reduce 1% of the annual emissions in the city of Izmir. In line with this target, this study worked on the integration of a liquid solvent-based DACS system. Primarily, the emissions within the city boundaries were calculated based on the calculation method of each sector.

Wu et al. (2022)-Preprint: Carbon Dioxide Removal via Macroalgae Open-ocean Mariculture and Sinking: An Earth System Modeling Study

Jiajun Wu, David P. Keller, Andreas Oschlies IN: Earth Syst. Dynam. Discuss. [preprint], https://doi.org/10.5194/esd-2021-104, in review, 2022

In this study, the authors dicuss open-ocean macroalgae mariculture and sinking (MOS) as ocean-based carbon dioxide removal (CDR) method. The results suggest that MOS has a considerable potential as an ocean-based CDR method. However, they argue that MOS has inherent side effects on marine ecosystems and biogeochemistry, which will require a careful evaluation beyond this first idealized modeling study.

Zeng et al. (2022): Large-scale CO2 removal by enhanced carbonate weathering from changes in land-use practices

SiboZeng, ZaihuaLiu, ChrisGroves IN: Earth-Science Reviews 225, 2022, 103915, https://doi.org/10.1016/j.earscirev.2021.103915

Continental rock weathering exerts a negative feedback on global warming by removing atmospheric CO2. Using an equilibrium modeling approach and results of the CMIP6 GCM model, the authors estimate the actual total CO2 removal by the weathering of both carbonate bedrock and carbonate-rich soils, at the global scale.
