📝RESEARCH PAPERS
Deployment expectations of multi-gigatonne scale carbon removal could have adverse impacts on Asia’s energy-water-land nexus
Ampah, J.D., Jin, C., Liu, H. et al. (2024). Deployment expectations of multi-gigatonne scale carbon removal could have adverse impacts on Asia’s energy-water-land nexus. Nature Communications, 15, 6342.
Synopsis: Future global carbon dioxide removal efforts may focus on Asia, but there’s limited knowledge of how Asian countries will manage energy-land-water systems under varying CDR scales. Modeling in this study shows high CDR reliance results in 8 GtCO2yr−1 emissions by 2050, compared to less than 1 GtCO2yr−1 with moderate-to-low CDR. High CDR expectations could delay net zero targets and increase land and fertilizer use for bioenergy crops. Asian regions should prioritize emission reductions while leveraging CDR advantages when feasible.
Next steps for assessing ocean iron fertilization for marine carbon dioxide removal
Buesseler, K., Bianchi, D., Chai, F., Cullen, J. T., Estapa, M., Hawco, N., ... & Yoon, J. E. Next steps for assessing ocean iron fertilization for marine carbon dioxide removal. Frontiers in Climate, 6, 1430957.
Synopsis: Ocean iron fertilization (OIF) has been studied extensively as a method for mCDR, yet previous studies failed to measure the durability of carbon storage. A new metric, the “centennial tonne,” is introduced to assess carbon sequestration. Five key activities are proposed: field studies, improved modeling, enhanced monitoring and verification, new iron sources, and public support and governance. These efforts, led by Exploring Ocean Iron Solutions (ExOIS), aim to responsibly evaluate and potentially deploy OIF, which could be a cost-effective, scalable, and rapid mCDR approach. Now is the time for actionable studies to begin.
Mine waste rock as a soil amendment for enhanced weathering, ecosystem services, and bioenergy production
Russell, M. D., Heckman, K., Pan, L., Ye, X., Zalesny, R. S., & Kane, E. S. Mine waste rock as a soil amendment for enhanced weathering, ecosystem services, and bioenergy production. Frontiers in Earth Science, 12, 1414437.
Synopsis: Enhanced weathering of terrestrial rock can remove CO2 from the atmosphere. This study shows that amended mining waste can be effectively weathered in soil with fast-growing willows (Salix matsudana Koidz. ⨯ S. alba L. 'Austree'). This approach minimizes emissions from material processing and transportation. The willows tolerated high metal concentrations and sequestered carbon as bicarbonate. During peak growth, soil with 25% mining waste sequestered 4.5 times more inorganic carbon than unamended soil and increased pH by up to two units. This method also boosts soil fertility, offering a sustainable carbon sequestration strategy.
Minority groups, Indigenousness and Indigeneity, and place in social perceptions of future climate interventions
Sovacool, B. K., Baum, C. M., & Fritz, L. (2024). Minority groups, Indigenousness and Indigeneity, and place in social perceptions of future climate interventions. World Development, 183, 106719.
Synopsis: Radical climate interventions like carbon dioxide removal and solar radiation management have profound impacts on Indigenous peoples, minorities, and rural communities. This article uses surveys from 30 countries (n=30,284) to examine public preferences across 10 geoengineering technologies. Results show Indigenous and minority respondents are more familiar with and supportive of small-scale trials and engineered options compared to non-minority groups, who favor restrictions on solar radiation management and carbon removal. Urban respondents also support small-scale trials more than rural ones. Indigenous groups support policy incentives more, highlighting diverse views on climate interventions.
Oceanic anoxic event 3 in Arctic Canada—Arc volcanism and ocean fertilization drove anoxia
Grasby, S. E., Crowley, J. L., Mohr, M. T., Percival, J. B., Ardakani, O. H., Galloway, J., ... & Yuan, W. (2024). Oceanic anoxic event 3 in Arctic Canada—Arc volcanism and ocean fertilization drove anoxia. Geological Society of America Bulletin.
Synopsis: The global extent of the Late Cretaceous oceanic anoxic event 3 (OAE 3) is uncertain and was thought not to reach the Boreal Realm. This study examines black mudstones from the Smoking Hills Formation in Arctic Canada, revealing new U-Pb zircon ages (88.535−78.230 Ma) that align with OAE 3, suggesting a broader global impact. The formation's high organic matter content and REE patterns indicate ashfall from Cretaceous arc volcanism, linking volcanic activity to ocean fertilization and productivity. High metal loading from volcanism could affect geochemical markers like cadmium, complicating their use as productivity proxies.
Integrating bicarbonate-based microalgal production with alkaline sewage for ocean negative carbon emissions
Zhu, C., Hu, C., Liu, J., Chi, Z., & Jiao, N. (2024). Integrating bicarbonate-based microalgal production with alkaline sewage for ocean negative carbon emissions. Trends in Biotechnology.
Synopsis: Using sewage for ocean alkalinity enhancement (OAE) is a promising ocean negative carbon emissions (ONCE) approach due to its high carbon sequestration efficiency and low environmental risk. This perspective proposes integrating bicarbonate-based microalgal production with sewage alkalinity enhancement for ONCE. The spent alkaline microalgal medium is cheap or free for OAE, and the high-value microalgae produced make the process profitable. Future development prospects are discussed to enhance efficiency and sustainability. This novel idea aims for effective carbon neutralization and economic value simultaneously.
Asymmetric and Irreversible Response of Tropical Cyclone Potential Intensity to CO2 Removal
Huan, D., & Yan, Q. (2024). Asymmetric and irreversible response of tropical cyclone potential intensity to CO2 removal. Geophysical Research Letters, 51(14), e2024GL109269.
Synopsis: Understanding tropical cyclone (TC) intensity under CO2 removal scenarios is crucial for climate adaptation and policymaking. Idealized experiments with CO2 ramp-up and ramp-down (from 284.7 to 1,138.8 ppm) reveal an asymmetric and irreversible response of TC potential intensity to CO2 reduction. Potential intensity increases during CO2 ramp-down compared to ramp-up and does not fully return to initial values, even over decades to centuries. This is driven by increased thermodynamic disequilibrium from weakened surface winds due to El Niño-like warming and ocean temperature contrasts. These findings underscore the risks of stronger storms under negative carbon emissions pathways.
Optimizing land use for climate mitigation using nature based solution (NBS) strategy: a study on afforestation potential and carbon sequestration in Rajasthan, India
Gupta, S. K., Kanga, S., Meraj, G., Singh, S. K., Singh, S., Sajan, B., ... & Mishra, V. N. (2024). Optimizing land use for climate mitigation using nature based solution (NBS) strategy: a study on afforestation potential and carbon sequestration in Rajasthan, India. Discover Geoscience, 2(1), 36.
Synopsis: This study uses remote sensing and geospatial analysis to assess afforestation potential across the Rajasthan state, evaluating land suitability and carbon sequestration capabilities of various tree species. By integrating satellite imagery and terrain analysis, optimal areas for tree planting are identified, with findings indicating that 40% of Rajasthan is suitable for afforestation, yielding carbon sequestration rates of 2-8 tons per hectare per year. Species like Azadirachta indica (Neem) and Prosopis cineraria (Khejri) excel in short-term sequestration, while Phyllanthus emblica (Amla) and Ziziphus mauritiana (Ber) are better for long-term capture. This research emphasizes targeted afforestation as a nature-based solution for climate mitigation in Rajasthan, enhancing ecosystem resilience and supporting climate adaptation in arid regions.
Assisted tree migration can preserve the European forest carbon sink under climate change
Chakraborty, D., Ciceu, A., Ballian, D., Benito Garzón, M., Bolte, A., Bozic, G., ... & Schueler, S. (2024). Assisted tree migration can preserve the European forest carbon sink under climate change. Nature Climate Change, 1-8.
Synopsis: This study explores assisted migration to enhance forest tree resilience by transferring seed provenances based on species-specific climatic limits and local adaptations. We modeled scenarios for seven key European tree species, analyzing how species and seed provenance selection affect the annual above-ground carbon sink of regrowing juvenile forests. Replacing coniferous trees with deciduous species is necessary for increasing resilience. Using local seed provenances could decrease the current carbon sink (40 TgC yr−1) by 34–41% by 2061–2080, while using future-adapted seed provenances may maintain or even increase sinks to 48–60 TgC yr−1.
Direct observational evidence of strong CO2 uptake in the Southern Ocean
Dong, Y., Bakker, D. C., Bell, T. G., Yang, M., Landschützer, P., Hauck, J., ... & Liss, P. S. (2024). Direct observational evidence of strong CO2 uptake in the Southern Ocean. Science Advances, 10(30), eadn5781.
Synopsis: The Southern Ocean is vital for anthropogenic CO2 uptake but suffers from significant uncertainties in CO2 flux estimates. Using seven independent air-sea CO2 flux datasets, this study found a 25% stronger CO2 uptake than traditional shipboard estimates. Addressing upper ocean temperature gradients and improving temporal resolution can help resolve this discrepancy. The gas transfer velocity parameterization is not the main cause of disagreement; instead, profiling float data and biogeochemical models may underestimate CO2 uptake due to insufficient representation of small-scale high-flux events. Our findings suggest the Southern Ocean may absorb more CO2 than previously recognized, emphasizing the need for temperature corrections and higher resolution in bulk flux estimates.
Efficiency metrics for ocean alkalinity enhancement under responsive and prescribed atmosphere conditions
Tyka, M. D. Efficiency metrics for ocean alkalinity enhancement under responsive and prescribed atmosphere conditions, EGUsphere [preprint].
Synopsis: Ocean alkalinity enhancement (OAE) and direct ocean capture (DOC) are promising negative emissions technologies, but measuring induced CO2 uptake directly is challenging. This study compares different modeling approaches for assessing OAE efficiency, highlighting significant differences in oceanic CO2 inventories due to atmospheric feedback effects. Even small OAE deployments can lead to ocean CO2 offgassing, similar to direct air capture (DAC). Accurate metrics are crucial for assessing OAE efficiency for negative emissions credits versus global temperature effects. The paper also shows that the efficiency metric η(t) from prescribed atmospheric CO2 simulations aligns with a gradual DAC removal schedule in fully coupled systems.
Estimation of changes in carbon sequestration and its economic value with various stand density and rotation age of Pinus massoniana plantations in China
Bai, Y., & Ding, G. (2024). Estimation of changes in carbon sequestration and its economic value with various stand density and rotation age of Pinus massoniana plantations in China. Scientific Reports, 14(1), 16852.
Synopsis: Plantations are crucial for the global carbon cycle and climate change mitigation. This study investigates how planting density affects biomass carbon storage and economic value in Pinus massoniana plantations. Researchers found that low-density (2000 trees·ha−1) and high-density (4500 trees·ha−1) plantations yield similar volumes as they age, but higher densities reduce carbon sequestration rates. Extending rotation periods and lowering density can significantly increase timber and carbon income. These results highlight the importance of optimizing planting density and managing stand age to enhance carbon storage and profitability in future afforestation initiatives.
Global atmospheric methane uptake by upland tree woody surfaces
Gauci, V., Pangala, S. R., Shenkin, A., Barba, J., Bastviken, D., Figueiredo, V., ... & Malhi, Y. (2024). Global atmospheric methane uptake by upland tree woody surfaces. Nature, 631(8022), 796-800.
Synopsis: Methane is a significant greenhouse gas, yet the role of trees in the methane budget is unclear. This study investigates in situ woody surface methane exchange in upland tropical, temperate, and boreal forest trees. Researchers found that methane uptake on woody surfaces, particularly above 2 m, can dominate trees' net ecosystem contribution, resulting in a net methane sink. Stable carbon isotope measurements indicate microbial-mediated drawdown of methane on tree surfaces and tissues. Using terrestrial laser scanning to quantify global forest tree woody surface area, this study estimate that trees may contribute 24.6–49.9 Tg of atmospheric methane uptake annually. These findings suggest that the climate benefits of protecting and reforesting tropical and temperate forests may be greater than previously thought.
Enhancing CO2 storage and marine carbon sink based on seawater mineral carbonation
Liu, S. S., Song, J. M., Li, X. G., Yuan, H. M., Duan, L. Q., Li, S. C., ... & Ma, J. (2024). Enhancing CO2 storage and marine carbon sink based on seawater mineral carbonation. Marine Pollution Bulletin, 206, 116685.
Synopsis: This study reviews advancements in seawater mineral carbonation, focusing on CO2 storage and ocean chemical sequestration. CO2 storage relies on indirect mineral carbonation, involving CO2 dissolution, Ca/Mg extraction, and carbonate precipitation, which can be optimized with alkaline substances or electrochemical methods. Ocean chemical sequestration uses natural seawater for direct mineral carbonation, enhanced by specific materials to increase CO2 absorption and carbonate precipitation. The study evaluates the advantages and challenges of these technologies, including reaction rates, costs, and ecological impacts, highlighting seawater mineral carbonation's potential for significant CO2 storage and enhanced marine carbon sinks in the future.
Reduced accrual of mineral-associated organic matter after two years of enhanced rock weathering in cropland soils, though no net losses of soil organic carbon
Sokol, N. W., Sohng, J., Moreland, K., Slessarev, E., Goertzen, H., Schmidt, R., ... & Scow, K. (2024). Reduced accrual of mineral-associated organic matter after two years of enhanced rock weathering in cropland soils, though no net losses of soil organic carbon. Biogeochemistry, 1-17.
Synopsis: This study examines the impact of crushed meta-basalt rock on soil organic matter (SOM) in three irrigated cropland trials in California. After 2 years, mineral-associated organic matter (MAOM) stocks were lower in the topsoil (0–10 cm) of rock-treated plots compared to controls. Although total soil organic carbon and nitrogen remained stable, the accrual rates of MAOM-C and MAOM-N were reduced in amended plots. These findings suggest that ERW's effects on SOM should be evaluated over multiple years and in various contexts before large-scale deployment.
Direct air capture of CO2 using biochar prepared from sewage sludge: Adsorption capacity and kinetics
Liu, J., Wang, Z., Liang, C., Fang, K., Li, S., Guo, X., ... & Fang, M. (2024). Direct air capture of CO2 using biochar prepared from sewage sludge: Adsorption capacity and kinetics. Science of The Total Environment, 174887.
Synopsis: This study explores the use of amino-modified sewage sludge as a carbon dioxide adsorbent. The effects of preparation conditions on CO2 adsorption performance were analyzed, revealing that solid NaOH as an activator at 600 °C with a 20% modifier concentration yielded the best results, achieving 1.17 mmol/g CO2 capacity. This research promotes waste resource utilization while aiding CO2 emission reduction.
Closing the Loop: Unexamined Performance Trade-Offs of Integrating Direct Air Capture with (Bi)carbonate Electrolysis
Almajed, H. M., Kas, R., Brimley, P., Crow, A. M., Somoza-Tornos, A., Hodge, B. M., ... & Smith, W. A. (2024). Closing the Loop: Unexamined Performance Trade-Offs of Integrating Direct Air Capture with (Bi) carbonate Electrolysis. ACS Energy Letters, 9(5), 2472-2483.
Synopsis: This study evaluates the integration of air contactors with (bi)carbonate electrolyzers for efficient CO2 capture via electrolysis. Findings reveal that the presence of CO32– with HCO3– in contactor effluent significantly reduces electrolyzer performance, leading to CO2 capture fractions of ≤1%. The required larger contactors for (bi)carbonate electrolysis result in unfavorable economics, and solvent regeneration in electrolyzers is inadequate for effective CO2 recapture. The research suggests process modifications to enhance operational feasibility, providing insights into the practical implementation of direct air capture with (bi)carbonate electrolysis.
Improving estimations of GHG emissions and removals from land use change and forests in Brazil
Zimbres, B., Shimbo, J., Lenti, F., Brandão Jr, A., Souza, E., Azevedo, T., & Alencar, A. (2024). Improving estimations of GHG emissions and removals from land use change and forests in Brazil. Environmental Research Letters.
Synopsis: This study presents advancements in the SEEG Brazil Initiative’s GHG estimation method, detailing annual emissions and removals from land use change at a 30-m spatial scale from 1990 to 2019. The improved methodology includes municipality-level emissions analysis and updated land cover maps. Findings show emissions peaked at 2,150 Mt CO2e in 2003, with removals nearly offsetting emissions in 2010. Recent trends indicate rising emissions, jeopardizing Brazil’s Paris Agreement targets. Mitigating deforestation could reduce emissions from land use change by 96%, addressing 44% of total emissions.

💼JOB OPPORTUNITIES
Quantification of carbon sequestration during enhanced weathering: A novel trace elemental and isotopic approach at the University of Edinburgh | For UK Students only
"Enhanced rock weathering (ERW) involves the removal of atmospheric CO2 during silicate weathering of fine-grained basalt, which is spread on agricultural land. This process enhances natural weathering rates and thus the drawdown of atmospheric CO2 via associated rock carbonation reactions. The major challenge with ERW is how to measure and precisely quantify the amount of atmospheric CO2 removed and stored during the process. This project will aim to develop novel methods to quantify the drawdown of atmospheric CO2 and compare this with the CO2 budget of natural high weathering rate systems. The main objective of the project is to assess the viability of ERW as a long-term carbon offsetting tool. The student will work closely with UNDO, the industry partner, and have access to an exclusive range of samples from their large scale and long term global basalt spreading test sites. The student will be involved in sample collection from UNDOs test sites and other field missions to investigate and sample analogous natural systems, such as basaltic terranes with naturally high weathering rates (e.g The Azores, Iceland and Hawaii). Together this will be used to construct a carbon model and budget for the long-term contribution of ERW with the ultimate goal of assessing the suitability of the ERW technique as a tool to combat the global climate crisis."

How to Store Carbon Dioxide, Permanently | National Wildlife
“Excess carbon dioxide has been building up in our atmosphere since the Industrial Revolution and has overwhelmed our planet’s natural ability to absorb all those emissions. In addition to reforestation, habitat protection, and other natural solutions, we can capture CO2 directly from the air or from emissions sources and store that carbon underground, safely and permanently.”

ROCKCHAR. Co-Pyrolysis of biomass and industrial side products, Oxford 18. June 2024 | Maria-Elena Vorrath
“Carbon dioxide removal (CDR) is teamwork: The combination of Pyrogenic carbon and enhanced Mineral weathering for Carbon Capture and Storage (= PyMiCCS) is suggested to deliver the combined benefits of both CDR methods. As a soil amendment, biochar and carbonating minerals may increase both the supply and retention of nutrients, the water holding capacity and the soil pH. Synergistic co-benefits could be a faster mineral weathering through optimized hydrologic conditions in the soil from pyrogenic carbon. Meanwhile, adding minerals already to the pyrolysis feedstock may result in a higher yield of pyrogenic carbon per unit of biomass employed which might reduce costs per ton of CO2 removal (Buss et al., 2022). Here, we present an overview on the project ROCKCHAR where we created PyMiCCS by co-pyrolysis of industrial side products with biomass. Returned concrete, steelslag and fines from milling silicate rocks (basalt and dunite) are inexpensive and abundant but instead of using their potential for enhanced weathering they often end up as landfills or fillers in constructions. To use these materials for CDR we produce a PyMiCCS out of 30%wt minerals with spruce chips and soybean meal pyrolysed at 650°C for 15 minutes. The nutrient release and CDR potential of all materials are investigated in a soil column incubation experiment over six months. ROCKCHAR’s cooperation partners are Sibelco, Silicate, thyssenkrupp and Novocarbo and knowledge is exchanged with the Hamburg University of Technology and the Ithaka Institute for Carbon Strategies. The project is funded by the Klaus Tschira Boost Fund, a joint initiative of the German Scholars Organization and the Klaus Tschira Foundation.”
