RESEARCH PAPERS
Direct air capture of CO2 for solar fuel production in flow
Kar, S., Kim, D., Bin Mohamad Annuar, A., Sarma, B. B., Stanton, M., Lam, E., ... & Reisner, E. (2025). Direct air capture of CO2 for solar fuel production in flow. Nature Energy, 1-12.
Synopsis: This study presents a dual-bed direct air carbon capture and utilization flow reactor that converts atmospheric CO₂ into syngas (CO + H₂) using sunlight, without the need for high temperatures or pressures. The reactor captures CO₂ via a silica-amine adsorbent, then releases and converts it to syngas with a silica/alumina-titania-cobalt photocatalyst under concentrated light. The system operates diurnally, capturing CO₂ at night and converting it to syngas during the day, using the oxidation of depolymerized plastics as the counter-reaction.
Calcite is an efficient and low-cost material to enhance benthic weathering in shelf sediments of the Baltic Sea
Fuhr, M., Dale, A. W., Wallmann, K., Bährle, R., Kalapurakkal, H. T., Sommer, S., ... & Geilert, S. (2025). Calcite is an efficient and low-cost material to enhance benthic weathering in shelf sediments of the Baltic Sea. Communications Earth & Environment, 6(1), 106.
Synopsis: This study evaluates calcite and dunite for enhanced benthic weathering in the Baltic Sea as a marine carbon dioxide removal strategy. Laboratory experiments and modeling show that calcite achieves up to 10 times higher CO₂ uptake efficiency than dunite, making it the preferred material. Sequestration costs range from €82–462 per tonne for calcite, compared to €558–1920 for dunite. These findings may inform similar coastal carbon removal efforts globally in geochemically comparable regions.
Multiple planetary boundaries preclude biomass crops for carbon capture and storage outside of agricultural areas
Braun, J., Werner, C., Gerten, D., Stenzel, F., Schaphoff, S., & Lucht, W. (2025). Multiple planetary boundaries preclude biomass crops for carbon capture and storage outside of agricultural areas. Communications Earth & Environment, 6(1), 102.
Synopsis: Six of nine planetary boundaries are currently exceeded, with land use changes contributing significantly. This study models the potential for BECCS using Miscanthus plantations while considering constraints from planetary boundaries like nitrogen flows, freshwater change, land system change, and biosphere integrity. The results show that BECCS potential under these constraints is minimal (0.1 gigatons CO₂ per year), with biosphere integrity being the most impactful factor. The study emphasizes the need for a holistic approach to balancing climate mitigation and ecosystem preservation.
Global carbonate chemistry gradients reveal a negative feedback on ocean alkalinity enhancement
Lehmann, N., & Bach, L. T. (2025). Global carbonate chemistry gradients reveal a negative feedback on ocean alkalinity enhancement. Nature Geoscience, 1-7.
Synopsis: Ocean alkalinity enhancement shifts seawater carbonate equilibrium to sequester CO₂. However, it may affect calcifying organisms, like coccolithophores, by promoting increased calcification, potentially reducing alkalinity enhancement efficiency. Using satellite data, this study shows that the ratio of inorganic to organic carbon in coccolithophores is influenced by factors like nutrient stoichiometry and carbonate chemistry. Extreme alkalinity enhancement could reduce CO₂ removal potential by 2–29% by 2100, highlighting the need to consider biogeochemical feedbacks in evaluating ocean alkalinity strategies.
Accounting for retarded weathering products in comparing methods for quantifying carbon dioxide removal in a short-term enhanced weathering study
Guo, X., Liu, Y., Xie, T., Li, Y., Liu, H., & Wang, Q. (2025). Impact of Ecological Restoration on Carbon Sink Function in Coastal Wetlands: A Review. Water, 17(4), 488.
Synopsis: This study explores carbon dioxide removal via enhanced weathering (EW), where crushed silicate minerals are added to soils. The majority (92.7–98.3%) of weathering products remain in the soil profile, termed the retarded fraction. Some products precipitate as carbonate minerals or adsorb to soil surfaces. While soil-based mass balance methods help quantify weathering rates, actual CDR can only be accurately determined by accounting for the retarded fraction, influencing long-term carbon storage estimates.
Preserving carbon dioxide removal to serve critical needs
Shindell, D., & Rogelj, J. (2025). Preserving carbon dioxide removal to serve critical needs. Nature Climate Change, 1-6.
Synopsis: Carbon dioxide removal is essential for net-zero pathways, particularly to offset hard-to-abate (H2A) emissions and overshoot. Analyzing least-cost 1.5°C scenarios, this study finds that 78 of 81 pathways require all available sustainable CDR for H2A emissions. Using CDR for easier-to-decarbonize sectors raises long-term costs and risks unattainable net-zero goals. Shifting CDR use exclusively to H2A emissions and overshoot is crucial to minimizing system-wide costs and ensuring climate targets remain feasible.
Direct Air Capture with Graphene-Based Adsorbents
Favour, A. A. (2025). Direct Air Capture with Graphene-Based Adsorbents.
Synopsis: Graphene-based materials show strong potential for enhancing Direct Air Capture technology due to their high surface area, tunable porosity, and stability. This study examines graphene oxide, reduced graphene oxide, and functionalized graphene frameworks, analyzing CO₂ capture mechanisms and material modifications that improve efficiency. Integration with renewable energy and economic feasibility are also explored. Findings highlight graphene’s promise for scalable, energy-efficient CO₂ removal, supporting net-zero goals.
Towards carbon neutrality: Enhancing CO2 sequestration by plants to reduce carbon footprint
Skrzypczak, D., Gorazda, K., Mikula, K., Mironiuk, M., Kominko, H., Sawska, K., ... & Chojnacka, K. (2025). Towards carbon neutrality: Enhancing CO2 sequestration by plants to reduce carbon footprint. Science of The Total Environment, 966, 178763.
Synopsis: This research emphasizes plant-based CO₂ sequestration as a key strategy for carbon neutrality and climate change mitigation. It integrates process optimization, sustainable practices, precision agriculture, and bioengineering to enhance CO₂ absorption and ecosystem carbon storage. Using Life Cycle Assessment and Carbon Footprint Analysis, the study evaluates the environmental effectiveness of these strategies. Case studies highlight the importance of combining technology with sustainable farming practices to reduce carbon footprints and move toward global carbon neutrality.
Stability and carbon sequestration potential of bamboo biochar
Costa, C. R., de Souza, A. M., dos Santos, M. G. B., da Silva, I. G. R., Moraes, T. V., dos Santos, J. R., ... & Figueiredo, C. C. D. (2025). Stability and carbon sequestration potential of bamboo biochar. Biomass Conversion and Biorefinery, 1-16.
Synopsis: Biochar is a durable carbon sequestration technology, but its effectiveness depends on pyrolysis conditions. This study examined how temperature and residence time affect carbon stability in bamboo biochars. Higher temperatures increased stability, while longer residence times had a greater impact at lower temperatures. Key stability indices showed strong correlation, suggesting they can be used interchangeably. These findings improve understanding of biochar stability and enhance carbon credit assessment methods.
Storage potentials for carbon-rich products in Germany – a database and outlook on final storage of products derived from negative emission technologies
Diekmeier, S., Reiter, K., Henk, A., & Friebe, C. (2025). Storage potentials for carbon-rich products in Germany–a database and outlook on final storage of products derived from negative emission technologies. Earth System Science Data Discussions, 2025, 1-30.
Synopsis: To achieve the EU's net-zero emissions target by 2050, carbon dioxide removal and negative emissions technologies (NET) are crucial. The NETPEC project proposes using (photo-)electrochemical methods to convert CO₂ into stable products for long-term storage. The study identifies promising sites in Germany, focusing on repurposing mining areas for carbon storage. A database cataloging mining activities and storage potentials suggests that just 1% of these areas could provide significant storage capacity. This initiative offers a sustainable, cost-effective solution for large-scale carbon sequestration.
Assessing costs and constraints of forest residue disposal by pile burning
Barker, J., Voorhis, J., & Crotty, S. M. (2025). Assessing costs and constraints of forest residue disposal by pile burning. Frontiers in Forests and Global Change, 7, 1496190.
Synopsis: Pile burning reduces wildfire risk in fire-prone forests, but cost estimates remain limited. This study quantified costs via USFS data and expert interviews, finding that machine pile burning costs 80% more than reported, while hand pile burning costs 135% more. Key cost drivers include road proximity and terrain. Pile burning also emits significant pollutants, including >1.7 million MT CO2 annually. Shifting residues to carbon-negative uses, supported by policy incentives, is recommended for climate and economic benefits.
Impact of Ecological Restoration on Carbon Sink Function in Coastal Wetlands: A Review
Guo, X., Liu, Y., Xie, T., Li, Y., Liu, H., & Wang, Q. (2025). Impact of Ecological Restoration on Carbon Sink Function in Coastal Wetlands: A Review. Water, 17(4), 488.
Synopsis: Coastal blue carbon ecosystems, including mangroves, seagrass beds, and salt marshes, contribute over 50% of marine carbon reserves despite covering less than 0.5% of the seafloor. However, human activities have severely impacted these ecosystems, limiting their carbon sequestration potential. Ecological restoration, focusing on restoring hydrological conditions, managing invasive species, and rebuilding habitats, has become crucial to enhance carbon sinks. This paper reviews the research on coastal wetland carbon sinks and restoration strategies, emphasizing the integration of carbon sink enhancement into ecological restoration efforts.
Carbon finance for forest resilience in California
Elias, M., Yackulic, E., Duffy, K., Saksa, P., Sanchez, D. L., Pevzner, N., ... & Bracer, C. (2025). Carbon finance for forest resilience in California. Frontiers in Forests and Global Change, 7, 1507554.
Synopsis: Restoring resilient forests in California’s American River watershed can generate up to $6,100 per acre in carbon revenue, potentially funding forest management. Using a dynamic performance benchmark (DPB) framework, this study finds that thinning and prescribed fire initially reduce carbon but ultimately lower wildfire emissions and boost storage by 35 tCO2e per acre. Biomass utilization adds 6–23 tCO2e. These treatments enhance carbon stability and highlight the role of innovative conservation finance in climate mitigation.
Resilient tree-planting strategies for carbon dioxide removal under compounding climate and economic uncertainties
Cho, F. H. T., Aglonucci, P., Bateman, I. J., Lee, C., Lovett, A., Mancini, M. C., ... & Day, B. H. (2025). Resilient tree-planting strategies for carbon dioxide removal under compounding climate and economic uncertainties. Proceedings of the National Academy of Sciences.
Synopsis: Nations worldwide have pledged to expand forests to meet decarbonization targets, but planting decisions—species, locations, and numbers—are fraught with uncertainty. Using the UK as a case study, we assess climate and economic uncertainties and explore decision-making methods. Findings show that optimal strategies differ based on emissions scenarios, with mismatches incurring high costs. Despite risks, tree planting remains a cost-effective carbon removal method compared to alternatives.
Energy, Health, and Climate Costs of Carbon-Capture and Direct-Air-Capture versus 100%-Wind-Water-Solar Climate Policies in 149 Countries
Jacobson, M. Z., Fu, D., Sambor, D. J., & Mühlbauer, A. (2025). Energy, Health, and Climate Costs of Carbon-Capture and Direct-Air-Capture versus 100%-Wind-Water-Solar Climate Policies in 149 Countries. Environmental Science & Technology.
Synopsis: This study examines whether 149 countries can transition to 100% wind-water-solar (WWS) energy, reducing air pollution, CO₂ emissions, and energy insecurity. WWS cuts end-use energy by 54.4%, energy costs by 59.6%, and total social costs by 91.8%, with rapid payback times. In contrast, carbon capture (CC) and synthetic direct air capture (SDACC) raise social costs by $60–80 trillion per year, increasing pollution and energy use. Findings suggest prioritizing WWS over CC/SDACC for sustainable climate solutions.

The GigaTen Ep. 3 February 2025 | Tree Media
"Sebastian Manhart updates us on the CDR (carbon dioxide removal) industry in conversation with Leila Conners. The GigaTen is a newsletter that Sebastian posts monthly and Leila thought it would be an interesting conversation to update monthly as well. We think that CDR is important and a unifying pathway as it creates jobs, proposes new ways to manufacture materials and can remove CO2 as needed."
What’s pH Swing? The Science Behind Aeon Blue’s Carbon Capture Tech | Bite-Size Climate Tech
"This time, we're diving into pH Swing Carbon Capture with Deóis Ua Cearnaigh, CTO of Aeon Blue. pH Swing is a clever chemistry trick used to capture CO₂ . But how does it actually work? We explore this concept using a fun baking analogy—just like making bread requires both sour (yogurt) and bitter (baking soda) for balance, pH Swing leverages shifts in acidity to trap and release CO₂ efficiently."
Teen CEO Seeks to Transform Farming with Biochar | Biochar Today

In your graphic summarizing the carbon removal landscape, I would like to make an addition. We - Blue Skies Minerals - and others are developing ways to store carbon in mining wastes. Presently, we are developing a process to store carbon with tailings in underground mines at the kilotonne/yr scale, as well as a process to store carbon with tailings in surface (open pit) mines at the megatonnes/yr scale. You should inform yourself about this work and make the relevant addition to your graphic.
Feel free to contact me (andre@blueskiesminerals.com) for further information.
