Amann, Thorben; et al. 2020: “Enhanced Weathering and Related Element Fluxes – a Cropland Mesocosm Approach.”

Amann, Thorben, Jens Hartmann, Eric Struyf, Wagner de Oliveira Garcia, Elke K. Fischer, Ivan Janssens, Patrick Meire, and Jonas Schoelynck. 2020: “Enhanced Weathering and Related Element Fluxes – a Cropland Mesocosm Approach.” Biogeosciences 17 (1): 103–19. https://doi.org/10.5194/bg-17-103-2020.

‌"In order to evaluate the efficiency and side effects of Enhanced Weathering (EW), a mesocosm experiment was set up and agricultural soil from Belgium was amended with olivine-bearing dunite ground to two different grain sizes, while distinguishing setups with and without crops."

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. "

Haque, Fatima; et al. 2020: “CO2 Sequestration by Wollastonite-Amended Agricultural Soils – An Ontario Field Study.”

Haque, Fatima, Rafael M. Santos, and Yi Wai Chiang. 2020: “CO2 Sequestration by Wollastonite-Amended Agricultural Soils – An Ontario Field Study.” International Journal of Greenhouse Gas Control 97 (June 2020): 103017. https://doi.org/10.1016/j.ijggc.2020.103017.

"In the present study, wollastonite-amended soils were collected from three commercial-scale fields located in Ontario: a leafy vegetables farm in the town of Paris (Field 1); a potato farm in the settlement of Alliston (Field 2); and a soybean farm in the city of Woodstock (Field 3). Chemical and mineralogical assessments of these soils were conducted to determine their carbonate content and the fate of the wollastonite."

de Oliveira Garcia, Wagner; et al. 2020: “Impacts of Enhanced Weathering on Biomass Production for Negative Emission Technologies and Soil Hydrology.”

de Oliveira Garcia, Wagner, Thorben Amann, Jens Hartmann, Kristine Karstens, Alexander Popp, Lena R. Boysen, Pete Smith, and Daniel Goll. 2020: “Impacts of Enhanced Weathering on Biomass Production for Negative Emission Technologies and Soil Hydrology.” Biogeosciences 17 (7): 2107–33. https://doi.org/10.5194/bg-17-2107-2020.

‌"Here, we investigate the deployment of enhanced weathering (EW) to supply nutrients to areas of afforestation–reforestation and naturally growing forests (AR) and bioenergy grasses (BG) that are deficient in phosphorus (P), besides the impacts on soil hydrology. Using stoichiometric ratios and biomass estimates from two established vegetation models, we calculated the nutrient demand of AR and BG."

Zeng, Sibo, et al. 2019: “Sensitivity of the Global Carbonate Weathering Carbon-Sink Flux to Climate and Land-Use Changes.”

Zeng, Sibo, Zaihua Liu, and Georg Kaufmann. 2019: “Sensitivity of the Global Carbonate Weathering Carbon-Sink Flux to Climate and Land-Use Changes.” Nature Communications 10 (1). https://doi.org/10.1038/s41467-019-13772-4.

‌"Here, we show that there is likely to be a widespread and consistent increase in the global CCSF (ranging from + 9.8% (RCP4.5) to + 17.1% (RCP8.5)) over the period 1950–2100."

Kirchner, Julia S., et al. 2020: "Reducing CO2 Emissions of a Coal-Fired Power Plant via Accelerated Weathering of Limestone: Carbon Capture Efficiency and Environmental Safety."

Kirchner, Julia S., Andrew Berry, Frank Ohnemüller, Bernhard Schnetger, Egon Erich, Hans-Jürgen Brumsack, and Karsten A. Lettmann. 2020. “Reducing CO2 Emissions of a Coal-Fired Power Plant via Accelerated Weathering of Limestone: Carbon Capture Efficiency and Environmental Safety.” Environmental Science & Technology. 2020. https://pubs.acs.org/doi/abs/10.1021/acs.est.9b07009.

"Accelerated weathering of limestone (AWL) has been proposed as a tool to capture CO2 from effluent gas streams and store it primarily as bicarbonate in the marine environment. We evaluated the performance of the biggest AWL-reactor to date that was installed at a coal-fired power plant in Germany."

Gattuso, J.-P.; et al. (2019): Opportunities for increasing ocean action in climate strategies

Gattuso, J.-P.; et al. (2019): Opportunities for increasing ocean action in climate strategies. IDDRI, Policy Brief N°02/19.

"In this Policy Brief we assess 18 ocean-based measures to support climate policies and the revision of NDCs in the areas of mitigation and adaptation. Ocean-related measures should not be considered as a substitute for climate mitigation on land, which must also be strongly pursued for the benefit of the atmosphere as well as the ocean."

Smith, Pete; et al. (2019): Land-Management Options for Greenhouse Gas Removal and Their Impacts on Ecosystem Services and the Sustainable Development Goals

Smith, Pete; Adams, Justin; Beerling, David J.; Beringer, Tim; Calvin, Katherine V.; Fuss, Sabine et al. (2019): Land-Management Options for Greenhouse Gas Removal and Their Impacts on Ecosystem Services and the Sustainable Development Goals. In Annu. Rev. Environ. Resour. 44 (1), pp. 255–286. DOI: 10.1146/annurev-environ-101718-033129.

"Land-management options for greenhouse gas removal (GGR) include afforestation or reforestation (AR), wetland restoration, soil carbon sequestration (SCS), biochar, terrestrial enhanced weathering (TEW), and bioenergy with carbon capture and storage (BECCS). We assess the opportunities and risks associated with these options through the lens of their potential impacts on ecosystem services (Nature's Contributions to People; NCPs) and the United Nations Sustainable Development Goals (SDGs)."
