Science- Van Dam et al. (2021): Calcification-driven CO2 emissions exceed “Blue Carbon” sequestration in a carbonate seagrass meadow

Bryce R. Van Dam, Mary A. Zeller, Christian Lopes, Ashley R. Smyth, Michael E. Böttcher, Christopher L. Osburn, Tristan Zimmerman, Daniel Pröfrock, James W. Fourqurean, Helmuth Thomas IN: Science Advances Vol 7, Issue 51; DOI: 10.1126/sciadv.abj1372

Long-term “Blue Carbon” burial in seagrass meadows is complicated by other carbon and alkalinity exchanges that shape net carbon sequestration. In this paper, the authors argue that the net carbon sequestration potential of seagrass meadows may be overestimated if calcification-induced CO2 emissions are not accounted for, especially in regions where calcification rates exceed net primary production and burial.

Claustre et al. (2021): The Oceans’ Biological Carbon Pumps – Framework for a Research Observational Community Approach

Hervé Claustre, Louis Legendre, Philip W. Boyd, Marina Levy IN: Front. Mar. Sci. 8: 780052. doi: 10.3389/fmars.2021.780052

A recent paradigm explains that the downward pumping of biogenic carbon in the ocean is performed by the combined action of six different biological carbon pumps (BCPs): the biological gravitational pump, the physically driven pumps (Mixed Layer Pump, Eddy Subduction Pump and Large-scale Subduction Pump), and the animal-driven pumps (diurnal and seasonal vertical migrations of zooplankton and larger animals). Here, a research community approach is presented to implement the new paradigm through an integrated study of these BCPs in the World Ocean.

Figueredo et al. (2021): Development of Pure Silica CHA Membranes for CO2 Separation

Gabriel Gama da Silva Figueiredo, Daishi Takayama, Katsunori Ishii, Mikihiro Nomura, Takamasa Onoki , Takuya Okuno, Hiromasa Tawarayama, Shinji Ishikawa IN: Membranes 2021, 11(12), 926; https://doi.org/10.3390/membranes11120926

Thin pure-silica chabazite (Si-CHA) membranes have been synthesized by using a secondary growth method on a porous silica substrate. The CO2 permeance through the Si-CHA membrane on a porous silica substrate was twice as high as that through the membrane synthesized on a porous alumina substrate, which displayed a similar zeolite layer thickness.

Saidi et al. (2021): Zirconium-Based Metal Organic Frameworks for the Capture of Carbon Dioxide and Ethanol Vapour. A Comparative Study

Meryem Saidi, Phuoc Hoang Ho, Pankaj Yadav, Fabrice Salles, Clarence Charnay, Luc Girard, Leila Boukli-Hacene, Philippe Trens IN: Molecules 2021, 26, 7620, 19 pp. https://doi.org/10.3390/

This paper reports on the comparison of three zirconium-based metal organic frameworks (MOFs) for the capture of carbon dioxide and ethanol vapour at ambient conditions. In terms of efficiency, two parameters were evaluated by experimental and modeling means, namely the nature of the ligands and the size of the cavities.

Climate Now publishes the final video II in series on Carbon Capture and Storage

by ClimateNow.com

Last week, Climate Now released part II of the video series on Carbon Capture and Storage featuring Julio Friedmann and Howard Herzog. Part II analyzes the utilization, transport, and storage of captured CO2, and the associated costs, challenges, and scaling opportunities. This series is a resource for people looking to understand CCUS in a digestible and in-depth manner.

Xing et al. (2021): Potential of enhanced weathering of calcite in packed bubble columns with seawater for carbon dioxide removal

Lei Xing, Huw Pullin, Liam Bullock, Phil Renforth, Richard C. Darton, Aidong Yang IN: Chemical Engineering Journal, 2021, 134096, https://doi.org/10.1016/j.cej.2021.134096

In this work, the weathering of calcite with seawater was investigated in a reactor using air enriched with CO2. A mathematical model of the packed bubble column reactor was constructed with the key mass transfer and chemical reaction components validated with experimental data.

Fit for 2030 series: Commission takes first steps on carbon dioxide removal – clear accounting and permanence will be key

by Bellona Europa

Today, the European Commission has published its vision for Carbon Dioxide Removal (CDR) in the coming decades. Bellona welcomes the plan, which takes several important steps on accounting, transparency, verification and industrial decarbonisation, but cautions against the use of CDR as an offsetting tool, particularly in the context of carbon farming and the use of carbon in products.
