Experiment combining #mineralcarbonation & #enhancedweathering in soil. Despite near-complete slag weathering, most base cations ended up in soil sinks (e.g. clays). Result: very low CO₂ removal (<5%)

More weathering ≠ more CO₂ removal

#EnhancedWeathering alters soil organic carbon in complex ways.
Effects are mediated by biota & soil moisture.
Robust #CDR assessments require considering organic carbon.

Beyond Inorganic C: Soil Organic C as a Key Pathway for Carbon Sequestration in Enhanced Weathering Enhanced weathering involves spreading crushed silicates on soils. Upon weathering of the applied silicates, CO2 is captured via two pathways: pedogenic carbonate formation and leaching of bicarbonat....

@globalchangebio.bsky.social: Soil organic carbon (SOC) is key for #enhancedweathering. We found negligible inorganic CO₂ removal, but considerable SOC storage potential. @boitolucilla.bsky.social @arthurvienne.bsky.social @patrickfrings.bsky.social

Reviews and syntheses: Carbon vs. cation based MRV of Enhanced Rock Weathering and the issue of soil organic carbon Abstract. We discuss the “monitoring, reporting & verification” (MRV) strategy of Enhanced Weathering (EW) based on carbon accounting and argue that in open systems such as arable land, this approach ...

Current #MRV for #EnhancedWeathering focuses on bicarbonate export, but this may not capture total #CarbonRemoval, especially when soil retention is high.

We propose a cation-based MRV using solid soil samples as a more practical & reliable alternative.

Ideen fürs Klima: Diese Wand soll CO₂ auf dreierlei Art binden Die Wand, die CO₂ speichern kann, präsentiert auf einem Stand der Verbundstoffmesse JEC. Eine neuartige Wand aus Stein, Carbonfasern und Biokohle kann

Eine Wand, die mehr #CO2 binden und speichern kann, als ihre Produktion verursacht: Durch Carbonfasern, Pflanzenkohle und #enhancedweathering. Ich hab sie mir für @table.media mal angesehen (€):

Application complete. This week saw @cyrilmbachu.bsky.social complete the first application of material in his #EnhancedWeathering #CCUS study.

Now we enter the monitoring phase….

##Enhancedweathering, #CCS

Today, I commenced the application of quarry fines as feedstock in my #Enhancedweathering project, a crucial phase of my research. I anticipate exciting results in the coming months when the amount of carbon dioxide that will be sequestered in the process will be quantified. #CCS

Today, the multispectral imaging of my project site where #Enhancedweathering strategy will be deployed for carbon dioxide removal was conducted #CCS. Huge thanks to @annettelokier.bsky.social and @lokier.bsky.social

A beautiful morning to do a multispectral drone survey in @cyrilmbachu.bsky.social research area. #EnhancedWeathering #CCS #CDR

Today, a group of University of Derby PhD, MSc and UG students are presenting their research at the East Midlands Geological Society Conference @britgeosurvey.bsky.social

A plethora of subjects: #CCS #EnhancedWeathering #Geothermal #OceanAcidification #tectonics #ReservoirModelling

It was terrific that University of Derby botanist Dr Alireza Naqinezhad could join PhD Cyril Mbachu at his #EnhancedWeathering field site today. Adding another layer to Cyril’s integrated study in this fabulous rural setting. #CDR #CCS
