Research Associate in Carbon Mineralization with Enhanced Metal Recovery

Deadline: Aug 04, 2022

The Department of Earth and Atmospheric Sciences at the University of Alberta in Edmonton, Canada is hiring a Research Associate in carbon mineralization for enhanced recovery of critical metals. This includes both field trials and laboratory work as part of a collaboration with ANSTO, Monash University and Heriot-Watt University. The initial appointment is for 2 years with the possibility of turning the position into a continuing appointment.

Science – Seddon (2022): Harnessing the potential of nature-based solutions for mitigating and adapting to climate change

Nathalie Seddon IN: SCIENCE, 23 Jun 2022, Vol 376, Issue 6600, pp. 1410-1416; DOI: 10.1126/science.abn9668

This article gives an overview of recent research on the benefits and limits of nature-based solutions, including how they compare with technological approaches, and highlight critical areas for future research.

Jaschke and Biermann (2022): The policy discourse on negative emissions, land-based technologies, and the Global South

Gregor Jaschke and Frank Biermann IN: Global Environmental Change, Volume 75, July 2022, 102550, https://doi.org/10.1016/j.gloenvcha.2022.102550

This article analyzes the nascent policy discourse on negative emissions with a focus on land-based technologies (afforestation and reforestation, bioenergy with carbon capture and storage, biochar, soil carbon sequestration). The authors conclude that this policy discourse is largely centered in the Global North (mostly in the United States, the United Kingdom, and Germany), with only five organizations directly linked to the Global South. While the earlier policy discourse on negative emissions was linked to a more general “geoengineering” discourse, this link has loosened in the last years. Overall, in the documents that were studied, negative emissions technologies seem to become more accepted, and parts of the discourse shift towards deployment.

Nature – Qiu et al. (2022): Environmental trade-offs of direct air capture technologies in climate change mitigation toward 2100

Yang Qiu, Patrick Lamers, Vassilis Daioglou, Noah McQueen, Harmen-Sytze de Boer, Mathijs Harmsen, Jennifer Wilcox, André Bardow & Sangwon Suh IN: Nat Commun 13, 3635 (2022). https://doi.org/10.1038/s41467-022-31146-1

Direct air capture (DAC) is critical for achieving stringent climate targets, yet the environmental implications of its large-scale deployment have not been evaluated in this context. Performing a prospective life cycle assessment for two promising technologies in a series of climate change mitigation scenarios, the authors find that electricity sector decarbonization and DAC technology improvements are both indispensable to avoid environmental problem-shifting.

Ocean Carbon Conference

Thu, 14 July 2022; 10:00 – 16:00 BST by Centre for Climate Repair at Cambridge

A one day hybrid conference on ocean carbon sequestration: Marine Biomass Regeneration (MBR) is a project to regenerate biomass in the oceans and not only thereby support marine ecosystems but also enhance the drawdown CO2 from the atmosphere. The objective of the project is to emulate the role of whales which feed in the benthic waters and return to the surface to defecate. The natural biological pumping and recycling of nutrients to the surface ocean is therefore diminished.

Damartzis et al. (2022): Solvents for Membrane-Based Post-Combustion CO2 Capture for Potential Application in the Marine Environment

Theodoros Damartzis, Akrivi Asimakopoulou, Dimitrios Koutsonikolas, George Skevis, Chara Georgopoulou, George Dimopoulos, Lampros Nikolopoulos, Konstantinos Bougiouris , Hannes Richter ,Udo Lubenau, Solon Economopoulos, Cristina Perinu, David Hopkinson, Grigorios Panagakos IN: Appl. Sci. 12(12), 6100; https://doi.org/10.3390/app12126100

In this paper, the authors present an comprehensive review of the different solvents that can be used for post-combustion CO2 capture on-board ships. Furthermore, they investigated the solvents’ performance as determined by their inherent characteristics, properties, and behavior for a range of operating conditions against the strict shipping requirements.

Silva et al. (2022): A generalizable framework for enhanced natural climate solutions

Lucas C. R. Silva, Mary C. Wood, Bart R. Johnson, Michael R. Coughlan, Heather Brinton, Krista McGuire, Scott D. Bridgham IN: Plant Soil (2022). https://doi.org/10.1007/s11104-022-05472-8

Different land-use sectors compete for resources and incentives within and across geopolitical regions, resulting in divergent goals and inefficient prioritization of CO2 removal efforts. The authors propose a generalizable framework for Enhanced Natural Climate Solutions (NCS +), which they define as activities that can be coordinated to increase carbon drawdown and permanence on land while improving livelihoods and the provision of natural resources in vulnerable communities and ecosystems.
