Ostovari, Hesam; et al. (2020): Rock ‘n’ use of CO 2 : carbon footprint of carbon capture and utilization by mineralization

Ostovari, Hesam; Sternberg, André; Bardow, André (2020): Rock ‘n’ use of CO 2 : carbon footprint of carbon capture and utilization by mineralization. In Sustainable Energy Fuels 4 (9), pp. 4482–4496. DOI: 10.1039/D0SE00190B.

„To provide a sound assessment of the climate impacts of CCU by mineralization, we determine the carbon footprint of CCU by mineralization based on life cycle assessment. For this purpose, we analyze 7 pathways proposed in literature: 5 direct and 2 indirect mineralization pathways, considering serpentine, olivine, and steel slag as feedstock.“

Castree, Noel (2020): The Discourse and Reality of Carbon Dioxide Removal: Toward the Responsible Use of Metaphors in Post-normal Times

Castree, Noel (2020): The Discourse and Reality of Carbon Dioxide Removal: Toward the Responsible Use of Metaphors in Post-normal Times. In Front. Clim. 2, p. 33. DOI: 10.3389/fclim.2020.614014.

„There’s little doubt that a variety of CDR techniques will be employed worldwide in the decades and centuries to come. Together, these techniques will alter the character and functioning of the biosphere, hydrosphere, cryosphere, pedosphere, and atmosphere. More locally, they will have immediate impacts on people and place, within diverse national state contexts. However, for the moment CDR exists more in the realm of discourse than reality.“

Welch, Alex J.; et al. (2020): Bicarbonate or Carbonate Processes for Coupling Carbon Dioxide Capture and Electrochemical Conversion

Welch, Alex J.; Dunn, Emily; DuChene, Joseph S.; Atwater, Harry A. (2020): Bicarbonate or Carbonate Processes for Coupling Carbon Dioxide Capture and Electrochemical Conversion. In ACS Energy Lett. 5 (3), pp. 940–945. DOI: 10.1021/acsenergylett.0c00234.

„Here we explore an approach for the design of a CO2[nbsp]capture and conversion system: (i) formation of bicarbonate or carbonate ((bi)carbonate) through dissolution of CO2[nbsp]into basic solution; followed by (ii) electrochemical reduction to syngas or formate; and finally (iii) transformation into useful chemicals, fuels, and materials.“

Ng, W. Y.; et al. (2020): Ranking negative emissions technologies under uncertainty

Ng, W. Y.; Low, C. X.; Putra, Z. A.; Aviso, K. B.; Promentilla, M.A.B.; Tan, R. R. (2020): Ranking negative emissions technologies under uncertainty. In Heliyon 6 (12), e05730. DOI: 10.1016/j.heliyon.2020.e05730.

„Given that there are multiple available NETs that need to be evaluated based on multiple criteria, there is a need for a systematic method for ranking and prioritizing them. Furthermore, the uncertainty in estimating the techno-economic performance levels of NETs is a major challenge. In this work, an integrated model of fuzzy analytical hierarchy process (AHP) and interval-extended Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) is proposed to address the multiple criteria, together with data uncertainties.“

Lockley, Andrew; et al. (2020): Glacier geoengineering to address sea-level rise: A geotechnical approach

Lockley, Andrew; Wolovick, Michael; Keefer, Bowie; Gladstone, Rupert; Zhao, Li-Yun; Moore, John C. (2020): Glacier geoengineering to address sea-level rise: A geotechnical approach. In Advances in Climate Change Research. DOI: 10.1016/j.accre.2020.11.008.

„This study summarises novel and extant geotechnical techniques for glacier restraint, identifying candidates for further research. These include draining or freezing the bed; altering surface albedo; creating obstacles: retaining snow; stiffening shear margins with ice; blocking warm sea water entry; thickening ice shelves (increasing buttressing, and strengthening fractured shelves against disintegration); as well as using regional climate engineering or local cloud seeding to cool the glacier or add snow.“
