Macreadie et al. (2022): Operationalizing marketable blue carbon

Peter I. Macreadie, Alistar I. Robertson, Bernadette Spinks, Matthew P. Adams, Jennifer M. Atchison …[+ 24 authors] IN: One Earth, Perspective, Volume 5 (5), pp. 485-492, Open AccessDOI:https://doi.org/10.1016/j.oneear.2022.04.005

The global carbon sequestration and avoided emissions potentially achieved via blue carbon is high (∼3% of annual global greenhouse gas emissions); however, it is limited by multidisciplinary and interacting uncertainties spanning the social, governance, financial, and technological dimensions. The authors compiled a transdisciplinary team of experts to elucidate these challenges and identify a way forward.

Castro-Muñoz et al. (2022): A new relevant membrane application: CO2 direct air capture (DAC)

Roberto Castro-Muñoz, Moh, Zamidi Ahmad, Magdalena Malankowska, Joaquín Coronas IN: Chemical Engineering Journal, 137047, https://doi.org/10.1016/j.cej.2022.137047

This paper gives a perspective of the ongoing research and attempts of DAC applications via membrane separation and introduces the main membrane materials and types used for CO2 separation. Finally, the process considerations for DAC using membranes are stated to guide the new researchers in the field.

Zhu et al. (2022): Unlocking the potential of hydraulic fracturing flowback and produced water for CO2 removal via mineral carbonation

Bizhou Zhu, Siobhan A. Wilson, Nina Zeyen, Maija J. Raudsepp, Ashkan Zolfaghari, Baolin Wang, Ben J. Rostron, Katherine N. Snihur, Konstantinvon Gunten, Anna L. Harrison, Daniel S. Alessi IN: Applied Geochemistry,105345, https://doi.org/10.1016/j.apgeochem.2022.105345

Flowback and produced water (FPW) generated by hydraulic fracturing operations is highly saline and contains elevated concentration of ions including calcium and magnesium. Here, the authors investigate the use of FPW as a source of calcium and magnesium for carbon dioxide (CO2) capture and storage in carbonate minerals.

Yan et al. (2022): An Electrochemical Hydrogen-Looping System for Low-Cost CO2 Capture from Seawater

Litao Yan, Jie Bao, Yuyan Shao, Wei Wang IN: ACS Energy Lett. 2022, 7, https://doi.org/10.1021/acsenergylett.2c00396

In this work, the authors developed an electrochemical hydrogen-looping (EHL) system that capitalizes on the generation of proton and OH from seawater. A CO2 capture efficiency as high as 91% is achieved for their EHL flow cell.

Freeman (2022): Tools for climate solutions: Developing techniques for marine carbon dioxide removal measurement, reporting and validation

Simon Freeman IN: The Journal of the Acoustical Society of America 151, A242 (2022); https://doi.org/10.1121/10.0011197

The author discuss ARPA-E’s interest in carbon sensing approaches, including passive and active acoustic techniques, which could rapidly quantify ocean carbon flux at scale and introduce powerful tools to address the challenges of mitigating climate impacts at sea.

Kikkawa et al. (2022): Direct Air Capture of CO2 Using a Liquid Amine–Solid Carbamic Acid Phase-Separation System Using Diamines Bearing an Aminocyclohexyl Group

Soichi Kikkawa, Kazushi Amamoto, Yu Fujiki, Jun Hirayama, Gen Kato, Hiroki Miura, Tetsuya Shishido, Seiji Yamazoe IN: ACS (American Chemical Society) Environment; https://doi.org/10.1021/acsenvironau.1c00065

The phase separation between a liquid amine and the solid carbamic acid exhibited >99% CO2 removal efficiency under a 400 ppm CO2 flow system using diamines bearing an aminocyclohexyl group. Among them, isophorone diamine [IPDA; 3-(aminomethyl)-3,5,5-trimethylcyclohexylamine] exhibited the highest CO2 removal efficiency.

Abdelhamid [preprint]: A Review on Removal of Carbon Dioxide (CO2) using Zeolitic Imidazolate Frameworks: Adsorption and Conversion via Catalysis

Hani Nasser Abdelhamid IN: ChemRxiv. Cambridge: Cambridge Open Engage; 2022 (Preprint, not peer reviewed)

The author reviewed ZIF-based materials for CO2 removal via adsorption and catalysis (e.g., cycloaddition, carboxylation, hydrogenation, N-formylation, electrocatalysis, and photocatalysis). In addition, recent development methods such as membrane synthesis and ways to improve the gas separation performance of ZIF membranes were highlighted.

Nature-Cobo et al. (2022): Human and planetary health implications of negative emissions technologies

Selene Cobo, Ángel Galán-Martín, Victor Tulus, Mark A. J. Huijbregts, Gonzalo Guillén-Gosálbez IN: Nat Commun 13, 2535 (2022). https://doi.org/10.1038/s41467-022-30136-7

The authors evaluate the impacts of Direct Air Capture and Bioenergy with Carbon Capture and Storage (DACCS and BECCS), finding that removing 5.9 Gtonne/year CO2 can prevent <9·102 disability-adjusted life years per million people annually, relative to a baseline without NETs.

Bustillos et al. (2022): Process Simulations Reveal the Carbon Dioxide Removal Potential of a Process That Mineralizes Industrial Waste Streams via an Ion Exchange-Based Regenerable pH Swing

Steven Bustillos, Dale Prentice, Erika Callagon La Plante, Bu Wang, Gaurav Sant, Dante Simonetti IN: ACS Sustainable Chem. Eng. 2022, https://doi.org/10.1021/acssuschemeng.2c0045

Herein, geochemical and process-modeling software was used to identify the optimum thermodynamic conditions and to quantify the energy intensity and CO2 reduction potential of a process that sequesters CO2 (dissolved in wastewater) as solid calcium carbonate (CaCO3).

Johansson et al. (2022): Envisioning sustainable carbon sequestration in Swedish farmland

Emma Li Johansson, Sara Brogaard, Lova Brodin IN: Environmental Science & Policy Vol.135, pp. 16-25, https://doi.org/10.1016/j.envsci.2022.04.005

The overall aim of this research is to imagine Swedish farms as carbon sinks rather than sources, and how to re-design the current farm- and food system to also address other social, economic, and environmental sustainability challenges. This paper is the outcome of two visioning workshops together with participants in an ongoing initiative called Swedish Carbon Sequestration [Svensk Kolinlagring].
