Job: Postdoctoral research position in enhanced rock weathering and CO2 mineralization (Trent University)

Deadline: 28. August 2020

"Applications are invited for a postdoctoral position at Trent University to carry out research on enhanced rock weathering (ERW) and CO2 mineralization for carbon dioxide removal. The successful applicant will conduct laboratory experiments to study mineral-water-gas interactions and/or microbially mediated processes as it relates to accelerating ERW and CO2 mineralization using mine wastes."

Job: Research Associate (Fixed Term) at the Cambridge Judge Business School

Deadline: 06. September 2020

"The Research Associate will support a new pan-European, multi-institution consortium (NEGEM) focused on assessing carbon dioxide gas removal (CDR) options such as bioenergy with CCS (BECCS), direct air capture of CO2 with CO2 storage (DACCS), enhanced weathering, afforestation, soil carbon sequestration and other negative emissions technologies and practices (NETPs)."

Podcast: Nori: Appropriations & carbon removal, the Biden-Sanders climate plan, & enhanced rock weathering in croplands

"Here are the articles we discussed this week:

  • Carbon removal represented in the Appropriations process in both Energy & Water and Agriculture.
  • The Biden-Sanders climate plan: "Biden-Sanders Unity Task Force Recommendations: Combating the Climate Crisis and Pursuing Environmental Justice".
  • "Potential for large-scale CO2 removal via enhanced rock weathering with croplands" in Nature."

Phys.org: Applying rock dust to croplands could absorb up to 2 billion tonnes of CO2 from the atmosphere

"In the first nation-by-nation assessment, published in Nature, scientists have demonstrated the method's potential for carbon drawdown by major economies, and identified the costs and engineering challenges of scaling up the approach to help meet ambitious global CO2 removal targets."

Beerling, David J.; et al. (2020): Potential for large-scale CO2 removal via enhanced rock weathering with croplands

Beerling, David J.; Kantzas, Euripides P.; Lomas, Mark R.; Wade, Peter; Eufrasio, Rafael M.; Renforth, Phil et al. (2020): Potential for large-scale CO2 removal via enhanced rock weathering with croplands. In Nature 583 (7815), pp. 242–248. DOI: 10.1038/s41586-020-2448-9.

"Here we use an integrated performance modelling approach to make an initial techno-economic assessment for 2050, quantifying how CDR potential and costs vary among nations in relation to business-as-usual energy policies and policies consistent with limiting future warming to 2 degrees Celsius."

Noah McQueen; et al. (2020): Ambient weathering of magnesium oxide for CO 2 removal from air

Noah McQueen; Peter Kelemen; Greg Dipple; Phil Renforth; Jennifer Wilcox (2020): Ambient weathering of magnesium oxide for CO 2 removal from air. In Nat Commun 11. DOI: 10.1038/s41467-020-16510-3.

"Here we detail a land-based enhanced weathering cycle utilizing magnesite (MgCO3) feedstock to repeatedly capture CO2 from the atmosphere. In this process, MgCO3 is calcined, producing caustic magnesia (MgO) and high-purity CO2."

Clark, Deirdre E.; et al. 2020: “CarbFix2: CO2 and H2S Mineralization during 3.5 years of Continuous Injection into Basaltic Rocks at More than 250 °C.”

Clark, Deirdre E., Eric H. Oelkers, Ingvi Gunnarsson, Bergur Sigfússon, Sandra Ó. Snæbjörnsdóttir, Edda S. Aradóttir, and Sigurður R. Gíslason. 2020: “CarbFix2: CO2 and H2S Mineralization during 3.5 years of Continuous Injection into Basaltic Rocks at More than 250 °C.” Geochimica et Cosmochimica Acta 279 (June): 45–66. https://doi.org/10.1016/j.gca.2020.03.039.

‌"The CarbFix method was upscaled at the Hellisheiði geothermal power plant to inject and mineralize the plant’s CO2 and H2S emissions in June 2014. This approach first captures the gases by their dissolution in water, and the resulting gas-charged water is injected into subsurface basalts. "
