Scott, Allan; et al. (2021): Transformation of abundant magnesium silicate minerals for enhanced CO2 sequestration

Scott, Allan; Oze, Christopher; Shah, Vineet; Yang, Nan; Shanks, Barney; Cheeseman, Chris et al. (2021): Transformation of abundant magnesium silicate minerals for enhanced CO2 sequestration. In Commun Earth Environ 2 (1), pp. 1–6. DOI: 10.1038/s43247-021-00099-6.

"Here we show a novel low-carbon method of producing Mg(OH)2, from globally abundant olivine-rich silicate rocks. A combination of acid digestion and electrolysis of olivine were used to produce Mg(OH)2 in a fully recoverable system."

Yang, Judy Q.; et al. (2021): 4D imaging reveals mechanisms of clay-carbon protection and release

Yang, Judy Q.; Zhang, Xinning; Bourg, Ian C.; Stone, Howard A. (2021): 4D imaging reveals mechanisms of clay-carbon protection and release. In Nat Comms 12 (1), p. 622. DOI: 10.1038/s41467-020-20798-6.

"Here we reveal the spatiotemporal dynamics of carbon sorption and release within model clay aggregates and the role of enzymatic decomposition by directly imaging a transparent smectite clay on a microfluidic chip. We demonstrate that clay-carbon protection is due to the quasi-irreversible sorption of high molecular-weight sugars within clay aggregates and the exclusion of bacteria from these aggregates. We show that this physically-protected carbon can be enzymatically broken down into fragments that are released into solution. Further, we suggest improvements relevant to soil carbon models."

Friggens, Nina L.; et al. (2020): Tree planting in organic soils does not result in net carbon sequestration on decadal timescales

Friggens, Nina L.; Hester, Alison J.; Mitchell, Ruth J.; Parker, Thomas C.; Subke, Jens-Arne; Wookey, Philip A. (2020): Tree planting in organic soils does not result in net carbon sequestration on decadal timescales. In Glob Chang Biol 26 (9), pp. 5178–5188. DOI: 10.1111/gcb.15229.

"We show that planting two native tree species (Betula pubescens and Pinus sylvestris), of widespread Eurasian distribution, onto heather (Calluna vulgaris) moorland with podzolic and peaty podzolic soils in Scotland, did not lead to an increase in net ecosystem C stock 12 or 39 years after planting."

Lefebvre, David; et al. (2020): Modelling the potential for soil carbon sequestration using biochar from sugarcane residues in Brazil

Lefebvre, David; Williams, Adrian; Meersmans, Jeroen; Kirk, Guy J. D.; Sohi, Saran; Goglio, Pietro; Smith, Pete (2020): Modelling the potential for soil carbon sequestration using biochar from sugarcane residues in Brazil. In Sci Rep 10 (1), p. 19479. DOI: 10.1038/s41598-020-76470-y.

"Sugarcane (Saccharum officinarum L.) cultivation leaves behind around 20 t ha−1 of biomass residue after harvest and processing. We investigated the potential for sequestering carbon (C) in soil with these residues by partially converting them into biochar (recalcitrant carbon-rich material)."

Project: ConserWater

"Using our AIs, we are launching the world's first international soil carbon market where corporations, governments and individuals can pay to offset their carbon dioxide emissions, and farmers can get paid to increase their soil carbon levels."
