RESEARCH PAPERS
Applying minerals to soil to draw down atmospheric carbon dioxide through synergistic organic and inorganic pathways
Buss, W., Hasemer, H., Sokol, N. W., Rohling, E. J., & Borevitz, J. (2024). Applying minerals to soil to draw down atmospheric carbon dioxide through synergistic organic and inorganic pathways. Communications Earth & Environment, 5(1), 602.
Synopsis: Soil minerals can sequester atmospheric CO2 through organic and inorganic processes. This study explores three methods for carbon removal: (1) spreading calcium- and magnesium-rich rocks for enhanced weathering, (2) mineral doping of biomass to improve biochar stability, and (3) applying minerals to increase soil organic carbon. Synergies between these approaches can enhance carbon sequestration, particularly with primary silicates like basalt. Optimizing these interactions could yield significant economic and environmental benefits.
Module optimization and array design of moisture swing direct air capture based on 2D-3D coupled analysis
He, M., Wang, T., Nie, H., Fang, H., Liu, W., Dong, H., ... & Gao, X. (2024). Module optimization and array design of moisture swing direct air capture based on 2D-3D coupled analysis. Energy Conversion and Management, 321, 119062.
Synopsis: Direct Air Capture is key to offsetting carbon emissions, and Moisture Swing Adsorption (MSA) offers energy-saving potential by switching between adsorption and desorption via humidity changes. Using a 2D-3D model, a moisture swing DAC array was optimized in this study, revealing that a 50-60% capture rate reduced energy use to 873.55 kWh/t CO2 and costs to $209.17/t CO2. Deployment on the Ordos Plateau further lowered costs and energy use, with passive adsorption at high wind speeds cutting energy to 408.89 kWh/t CO2.
Carbon dioxide fertilization enhanced carbon sink offset by climate change and land use in Amazonia on a centennial scale
Chen, B., Xu, X., Wang, S., Yang, T., Liu, Z., & Falk, S. (2024). Carbon dioxide fertilization enhanced carbon sink offset by climate change and land use in Amazonia on a centennial scale. Science of The Total Environment, 176903.
Synopsis: The Amazon, the largest tropical forest, is vital for carbon sequestration, yet its capacity is declining due to climate variability, deforestation, and fires. This study utilized dynamic global vegetation models to examine carbon dynamics from 1901 to 2021, revealing significant variations in net land carbon fluxes, with the Amazon acting as a net carbon sink (40.02 ± 242.64 Tg C yr−1). Net biome productivity (NBP) shifted from a decreasing trend (−3.78 Tg C yr−2) from 1901 to 1959 to an increasing trend (2.39 Tg C yr−2) from 1960 to 2021. While rising atmospheric CO2 enhanced NBP by 36.40 ± 8.39 Pg C, this was offset by land-use change (−18.84 ± 12.02 Pg C) and climate change (−10.03 ± 5.00 Pg C), highlighting the urgent need for sustainable management to preserve its role in the global climate system.
ZeroCAL: Eliminating Carbon Dioxide Emissions from Limestone’s Decomposition to Decarbonize Cement Production
Leão, A., Collin, M., Ghodkhande, S., Bouissonnié, A., Chen, X., Malin, B., ... & Sant, G. (2024). ZeroCAL: Eliminating Carbon Dioxide Emissions from Limestone’s Decomposition to Decarbonize Cement Production. ACS Sustainable Chemistry & Engineering.
Synopsis: This study presents the Zero Carbon Lime (ZeroCAL) process, which transforms CaCO3 into hydrated lime (Ca(OH)2) at ambient conditions while drastically reducing CO2 emissions to just 9 kg per tonne of Ca(OH)2 produced. Utilizing an aqueous flow-electrolysis/pH-swing method, the process involves chelator-promoted dissolution, nanofiltration for calcium enrichment, and electrolytic precipitation. By leveraging seawater and coproducing hydrogen and sodium bicarbonate, the ZeroCAL process offers a sustainable approach to decarbonizing cement production, with implications for cost-effective CO2 mineralization.
Towards a modular, multi-ecosystem monitoring, reporting and verification (MRV) framework for soil organic carbon stock change assessment
Batjes, N. H., Ceschia, E., Heuvelink, G. B., Demenois, J., Le Maire, G., Cardinael, R., ... & van Egmond, F. (2024). Towards a modular, multi-ecosystem monitoring, reporting and verification (MRV) framework for soil organic carbon stock change assessment. Carbon Management, 15(1), 2410812.
Synopsis: Soils are the largest terrestrial reservoir of organic carbon but are susceptible to degradation. Accurate monitoring, reporting, and verification (MRV) of soil organic carbon stocks and greenhouse gas emissions are crucial for promoting sustainable land use practices and integrating carbon sequestration into national emission reduction targets. This study builds on an initial review of MRV schemes for croplands, grasslands, and forestlands, developing a modular, scalable MRV framework. We inventory and classify selected methodologies, scoring them on key characteristics. The primary challenge identified is monitoring. Finally, a conceptual workflow is presented for developing a prototype operational MRV tool.
Assessing the net carbon removal potential by a combination of direct air capture and recycled concrete aggregates carbonation
Chen, L., & Yang, A. (2025). Assessing the net carbon removal potential by a combination of direct air capture and recycled concrete aggregates carbonation. Resources, Conservation and Recycling, 212, 107940.
Synopsis: This study explored the CO2 removal potential by combining direct air capture with carbonation of recycled concrete aggregates (RCA). An industrial-scale model assessed key factors affecting carbonation duration and energy use. Lifecycle analysis compared two cases: (i) using pure CO2 with transport between DAC and carbonation, and (ii) onsite low-purity CO2 production. Case (ii) achieved 70% greater CO2 removal. The study highlights this approach’s potential and key factors for future research.
Early life stages of fish under ocean alkalinity enhancement in coastal plankton communities
Goldenberg, S. U., Riebesell, U., Brüggemann, D., Börner, G., Sswat, M., Folkvord, A., ... & Moyano, M. (2024). Early life stages of fish under ocean alkalinity enhancement in coastal plankton communities. Biogeosciences, 21(20), 4521-4532.
Synopsis: Ocean Alkalinity Enhancement (OAE) is a promising carbon dioxide removal method, but its impact on marine life is unclear. A 49-day mesocosm experiment studied early life stages of fish like Atlantic herring and cod under increased alkalinity and silicate levels. Despite significant changes in water chemistry, fish growth and survival were not impaired, and biomass increased. These results suggest resilience to OAE in some species, though other life stages and habitats may be more vulnerable.
A techno-economic and environmental evaluation of the integration of direct air capture with hydrogen derivatives production
Prats-Salvado, E., Monnerie, N., & Sattler, C. (2024). A techno-economic and environmental evaluation of the integration of direct air capture with hydrogen derivatives production. International Journal of Hydrogen Energy.
Synopsis: Carbon-neutral fuels are vital for decarbonizing hard-to-abate sectors. Solar redox cycles can produce them by splitting water and CO2, with the resulting synthesis gas converted to liquid fuels like methanol. This study explores integrating direct air capture (DAC) with solar redox cycles, proposing four strategies. The optimal setup, powered by waste heat, achieved a cost of $7.9/kg methanol and a climate impact of −450 g CO2e/kg. The study supports DAC integration in synthetic fuel production.
Impacts of Iron Salt Aerosol and Hydroxyl Radical Release on the Methane Lifetime
Horowitz, H. M. Impacts of Iron Salt Aerosol and Hydroxyl Radical Release on the Methane Lifetime.
Synopsis: Enhancing methane oxidation in the atmosphere using tropospheric hydroxyl (OH) or chlorine (Cl) radicals could help reduce greenhouse gas concentrations. This study employs a 3D atmospheric chemistry model to evaluate various OH- and Cl-based enhancement methods, focusing on their effectiveness in lowering methane levels and impacts on air quality and stratospheric ozone. Results indicate that iron salt aerosol may not effectively reduce global methane, while hydrogen peroxide approaches could achieve reductions, albeit with potentially impractical emissions. All methods increase surface particulate matter, and while Cl methods decrease ozone pollution, OH methods may worsen it in urban areas. Minimal changes in stratospheric ozone are expected after one year.
The dynamic trajectory of carbon dioxide removal from terrestrial ecosystem restoration: A critical review
Niu, S., Zhang, R., Wang, S., Wu, Y., Chen, W., Tian, D., ... & Yu, G. (2024). The dynamic trajectory of carbon dioxide removal from terrestrial ecosystem restoration: A critical review. Agricultural and Forest Meteorology, 358, 110244.
Synopsis: Climate change threatens global ecosystems, highlighting the need for nature-based solutions like ecosystem restoration for terrestrial carbon dioxide removal (TCDR). However, estimating TCDR remains uncertain due to static conditions in most projections. This paper reviews dynamic restoration trajectories for TCDR, emphasizing increased net primary productivity and carbon residence time. It highlights case studies across ecosystems and underscores the importance of considering restoration methods, biodiversity, and environmental changes for accurate TCDR predictions.
Modeling and planning optimization of carbon capture load based on direct air capture
DU, C., & ZHANG, X. Modeling and Planning Optimization of Carbon Capture Load Based on Direct Air Capture.
Synopsis: Direct air capture is a growing technology for removing CO2 from the atmosphere, requiring better operational understanding and planning. This paper analyzes the operational traits of absorption- and adsorption-based DAC, reviews engineering demonstrations, and identifies technological bottlenecks. It proposes a dual-layer optimization model to minimize investment and operational costs, incorporating subsidy mechanisms. Numerical analysis validates the model, offering insights and recommendations for DAC project design and implementation.
PhytOC sequestration characteristics and phytolith carbon sink capacity of the karst grasslands in southwest China
Luo, M., Wang, L., Liu, L., Song, L., Lu, X., & Sheng, M. (2024). PhytOC sequestration characteristics and phytolith carbon sink capacity of the karst grasslands in southwest China. Science of The Total Environment, 176949.
Synopsis: Grasslands play a crucial role in the global carbon cycle, and PhytOC (phytolith-occluded organic carbon) is a key stable carbon pool in these ecosystems. This study examined PhytOC sequestration in three karst grasslands in southwest China. Results showed that roots contain higher PhytOC than aboveground parts, with a sequestration rate of 7.34–15.93 kg·ha−1·yr−1. Karst grasslands have higher PhytOC sequestration rates than non-karst regions, influenced by soil silicon, pH, and nutrient stoichiometry.
Contestation in Social Acceptance of Direct Air Capture (DAC) Technologies in Korea by differing framings over governance principles
Oh, C. (2024). Contestation in Social Acceptance of Direct Air Capture (DAC) Technologies in Korea by differing framings over governance principles. Journal of Open Innovation: Technology, Market, and Complexity, 100403.
Synopsis: In 2023, Korea considered setting a separate mitigation target for Direct Air Capture alongside its carbon capture, storage, and utilization (CCUS) goals in its 2030 nationally determined contribution (NDC). Despite support, DAC was excluded from the final plan due to concerns about short-term targets, uncertainties in DAC's potential, and financial inefficiencies. This paper explores these debates and recommends aligning short- and long-term goals, supporting technology demonstrations, and clarifying the CCUS-DAC relationship.
Plant diversity drives positive microbial associations in the rhizosphere enhancing carbon use efficiency in agricultural soils
Domeignoz-Horta, L. A., Cappelli, S. L., Shrestha, R., Gerin, S., Lohila, A. K., Heinonsalo, J., ... & Laine, A. L. (2024). Plant diversity drives positive microbial associations in the rhizosphere enhancing carbon use efficiency in agricultural soils. Nature Communications, 15(1), 8065.
Synopsis: Expanding agriculture has significantly reduced soil carbon, necessitating effective management practices to enhance carbon retention in agroecosystems, which cover over 40% of Earth's land. This study explores the interaction between plants and soil microbes by implementing a diversity gradient through intercropping undersown species with barley in a large field trial, ranging from one to eight species. Results indicate that increased plant diversity promotes positive associations within the rhizosphere microbial community, enhancing carbon use efficiency. These findings suggest that boosting plant diversity can serve as a viable strategy to improve carbon retention in agricultural soils.
Biochar carbon removal from residues in Germany – Assessment from environmental and economic perspectives
Lenk, C., Zozmann, E., Bluhm, H., & Hirschl, B. (2024). Biochar carbon removal from residues in Germany–Assessment from environmental and economic perspectives. Environmental Research Letters.
Synopsis: Biochar carbon removal (BCR), derived from the pyrolysis of biomass, is gaining traction as a viable method for long-term atmospheric CO2 removal. This study critiques current BCR assessments in Germany, which typically focus on woody biomass and rely on outdated data. By examining BCR from forest residues, straw, and sewage sludge, the research evaluates its potential for negative emissions under contemporary techno-economic conditions. Utilizing life cycle assessment and stakeholder engagement, findings reveal BCR's environmental benefits in lowering greenhouse gas emissions compared to traditional residue treatments, while economic viability hinges on factors like plant scale and biomass type. The study emphasizes the need for supportive policies to scale BCR technology, contributing valuable insights to the discourse on carbon neutrality.
Hidden comet tails of marine snow impede ocean-based carbon sequestration
Chajwa, R., Flaum, E., Bidle, K. D., Van Mooy, B., & Prakash, M. (2024). Hidden comet tails of marine snow impede ocean-based carbon sequestration. Science, 386(6718), eadl5767.
Synopsis: Phytoplankton aggregates in the ocean create a natural carbon transport mechanism known as the "biological pump," sequestering 2 to 4.5 billion tons of atmospheric carbon annually. However, existing models lack a quantitative framework for marine snow's formation, sedimentation, and remineralization, leading to uncertainties in carbon flux estimates. This study investigates marine snow's sinking dynamics during an algal bloom in the Gulf of Maine. Using advanced microscopy and sediment traps, researchers observed that marine snow aggregates possess invisible comet tails of viscoelastic mucus, altering their sinking behavior. This discovery nearly doubles the estimated residence time of marine snow in the euphotic zone, suggesting significant overestimates in carbon flux assessments. The findings provide a new theoretical framework for understanding marine snow dynamics, highlighting the role of mucus viscoelasticity in carbon cycling and potential biogeochemical remediation strategies.

The complex path to market for low-carbon cement | Catalyst with Shayle Kann
"Getting the construction industry to try a novel form of cement is like turning a giant ship. It’s hard to redirect the immense momentum behind existing ways of doing business, especially involving cement, the most energy-intensive ingredient in concrete. Industry insiders point to tight margins, concerns about messing with the ingredients that literally hold up buildings, and the long list of stakeholders will agree to try a new material.
So how do you get a risk-averse construction supply chain to try decarbonized cement?
In this episode, Shayle talks to Leah Ellis, CEO and co-founder of Sublime Systems, a company that recently landed its first commercial deployment of decarbonized cement. (Shayle is an investor in Sublime). Shayle and Leah cover topics like:
-The long list of parties involved in a single pour of concrete
-Why the green premium is a burden for margin-squeezed contractors but “budget dust” for the building buyer
-How to align stakeholders, once there's buy-in from financers
-How a book-and-claim system could work for decarbonized cement
-How major concrete consumers, like governments, can create demand
-Why the boom in data center construction creates a window of opportunity for decarbonized construction materials"

Both EU-wide and global CDR policy is relevant to all CDR startups, yet with constrained resources, many struggle to stay up to date. The Quarterly Policy Update series aims to address this need and provide this resource to a wide audience.
For the third instalment of 2024, we've partnered with remove to spotlight the USA.
Join us as we give the floor to Holly Jean Buck, Associate Professor of Environment and Sustainability at University at Buffalo to share her contributions to the second edition of the State of CDR report, policy progress in the USA and her research on CDR communication in the region."
