RESEARCH PAPERS
Undermining climate action? Challenges of public-private co-financing of carbon removal in the Global North
Authors: Kirstine Lund Christiansen, Jonas Allesson, Guy Finkill, Nick Fitzpatrick, Inge-Merete Hougaard
Synopsis: The paper examines the growing use of co-financed bioenergy with carbon capture and storage (BECCS) projects, where governments and companies jointly fund carbon dioxide removal. The authors argue this model risks double-counting climate benefits, undermines the credibility of carbon offsets by failing additionality tests, and could worsen global climate inequality by favoring wealthy governments and large corporations with greater purchasing power.
Solar concentrated-light driven direct air capture with fast desorption kinetics using amine-modified monolithic composites
Authors: Fang Wang, Xuelin Xu, Zhonghai Zhang, Wendi Liu, Jinchi Mu, Jiandong Chen, Tao Wang
Synopsis: Researchers developed a concentrated-light-driven DAC system using a monolithic PEI/Ni/γ-Al₂O₃ adsorbent to improve CO₂ capture efficiency and reduce regeneration energy. The system achieved high CO₂ uptake, nearly 97% regeneration efficiency, and complete desorption in just two minutes at 70°C. The study also reveals how humidity changes the CO₂ capture mechanism and demonstrates stable performance over repeated cycles, highlighting the potential of light-powered DAC for negative emissions.
Assessing the effects of ocean alkalinity enhancement on marine protozoa: physiological dynamics and transcriptomic responses
Authors: Zuyuan Gao, Mengwen Pang, Mingjie Li, Yuzhen Ming, Hongbin Liu, Kedong Yin
Synopsis: Laboratory study investigated how two heterotrophic marine nanoflagellates respond to OAE. While both species experienced negative effects under acute exposure, their ability to acclimate differed, with high alkalinity reducing growth and altering cellular processes, particularly in one species. The findings suggest OAE could have species-specific impacts on marine protozoa, raising concerns about potential effects on marine biodiversity and ecosystem stability.
Interactive effects of basalt, B. subtilis, and soil moisture on maize physiology and nutrient uptake
Authors: Noemma Olagaray, Jonathan Edward Lambert, Tannis Thorlakson
Synopsis: An outdoor experiment explored how basalt application, microbial inoculation with Bacillus subtilis, and soil moisture interact to influence enhanced silicate weathering (ESW) in maize. Basalt improved silicon and several nutrient concentrations in plants, while the microbes enhanced silicon uptake and partly reduced early growth stress. The results show that the benefits of ESW depend strongly on soil biology and water availability, highlighting their importance for effective carbon removal and soil management.
The role of temperature and salinity on ocean alkalinity enhancement performance
Authors: Matias Saez Moreno, Jens Hartmann, Janine Börker, Peggy Bartsch, and Charly Andre Moras
Synopsis: Researchers compared the performance of three OAE feedstocks across different temperature and salinity conditions to evaluate their carbon removal potential. Sodium bicarbonate consistently delivered the intended alkalinity, while calcium hydroxide performed best in cold waters and magnesium hydroxide was slowed by high salinity. The findings show that OAE efficiency depends strongly on both feedstock choice and local ocean conditions, emphasizing the need to match materials to deployment environments.
Metal Accumulation Risks in Enhanced Rock Weathering: Risk Assessment Framework and Recommendations - Preprint
Authors: Noemma Olagaray, Jonathan Edward Lambert, Tannis Thorlakson
Synopsis: The authors developed the ERW Metal Accumulation Calculator (ERW-MAC) to assess soil metal accumulation risks from ERW. Modeling shows basalt feedstocks generally remain below regulatory thresholds despite raising some metal concentrations, while peridotite often results in elevated nickel and chromium levels. The study recommends a three-step risk assessment process—feedstock characterization, conservative modeling, and regulatory evaluation—supported by ongoing field monitoring to ensure safe ERW deployment.
Ideas and perspectives: Max MACS – constraining the potential global scale of Marine Anoxic Carbon Storage for CO2 removal
Authors: Morgan Reed Raven, Nitai Amiel, Dror L. Angel, James P. Barry, et al.
Synopsis: The paper evaluates the potential of Marine Anoxic Carbon Storage (MACS), a proposed carbon dioxide removal approach that stores plant-derived organic carbon in oxygen-free marine environments. While MACS could theoretically operate at gigatonne scale with limited environmental risks, significant uncertainties remain. The authors identify five key factors that could constrain large-scale deployment and outline priority research needed to assess its environmental impacts, feasibility, and role in future climate mitigation.
Synergistic enhancement of direct air capture by dual-amine functionalized γ-Al2O3 and high gravity adsorption in a rotating adsorption bed
Authors: Keju An, Dylan Wald, Kejun Chen, Ryan King
Synopsis: This study combines a dual-amine (PEI-TEPA) sorbent with a rotating adsorption bed (RAB) to improve DAC by overcoming gas–solid mass-transfer limitations. The optimized system achieved higher CO₂ uptake, faster adsorption, and maintained 87.6% of its capacity after ten regeneration cycles. The findings show that integrating advanced sorbent design with process intensification is more effective than material improvements alone, offering a promising pathway toward compact, high-efficiency DAC systems.
The role of atmospheric fast adjustment in the distinct precipitation response between increase and decrease of CO2 concentrations
Authors: Ilai Guendelman, Ivan Mitevski & Gabriel Vecchi
Synopsis: Researchers found that Earth’s hydrological response to decreasing CO₂ differs from its response to increasing CO₂, challenging the assumption that hydrological sensitivity remains constant. Climate model experiments show precipitation changes more per degree of warming during CO₂ halving than doubling, largely due to rapid atmospheric adjustments in longwave radiation. The findings also help explain hysteresis observed in abrupt CDR simulations, highlighting the importance of fast atmospheric processes in shaping precipitation responses.
Operating parameters and sorbent properties affecting ca (OH) 2 carbonation for direct air capture (DAC) applications
Authors: Yolanda A Criado, Carlos Bajo, Loreto Suarez, Roberto García
Synopsis: The research investigates how operating conditions and sorbent properties affect the maximum carbonation conversion of calcium hydroxide in DAC. Experiments show that relative humidity and sorbent surface area have the greatest influence on CO₂ uptake, while higher CO₂ concentrations speed initial reactions but can reduce overall conversion. The authors also develop an empirical model to predict carbonation performance, providing a practical tool for designing and optimizing Ca(OH)₂-based DAC systems.
Carbon fabrics for electrified direct air capture: From substrate morphology to module-scale operating trade-offs
Authors: Carla Esch, Jacqueline Kieven, Antonia Geiser, Roman Ryapushkin, Wibke Zängle, Matthias Wessling
Synopsis: Researchers evaluated electrically heated polyethyleneimine (PEI)-impregnated carbon fabric sorbents for DAC under realistic operating conditions. Although the sorbents showed high intrinsic CO₂ capacity, only 15–30% was utilized during continuous operation because performance was limited by gas transport rather than adsorption capacity. The findings indicate that improving module design, heat management, and dynamic sorbent utilization is more important than simply increasing sorbent capacity for efficient electrified DAC systems.
A new pathway to enhance the oceanic carbon sink: inorganic carbonate precipitation driven by calcium–alkali coupling
Authors: Shan Shan Liu, Jin Ming Song, Xue Gang Li, Hua Mao Yuan, Li Qin Duan et al.
Synopsis: Researchers tested a calcium–alkali coupling approach that enhances ocean carbon removal by converting dissolved inorganic carbon into solid calcium carbonate, promoting additional atmospheric CO₂ uptake as seawater re-equilibrates. Laboratory, mesocosm, and offshore field experiments demonstrated effective carbon removal with only limited short-term environmental impacts. While the method shows substantial theoretical potential for boosting the ocean carbon sink, its long-term effectiveness, ecological impacts, and scalability require further investigation.
Basalt-Based Enhanced Rock Weathering for Long-Term CO2 Storage: Insights from Mineral Carbonation Experiments
Authors: Pragalathan Rasaiah; Prerna Yogeshwar; Suraj Kumar; Jitendra S. Sangwai
Synopsis: Researchers evaluated basalt from India’s Rajmahal Traps for ERW as a permanent carbon dioxide removal strategy. Under optimized conditions, the basalt captured up to 9.72 g of CO₂ per kilogram, with analyses confirming the formation of stable carbonate minerals such as calcite and magnesite. The findings highlight Rajmahal basalt as a promising domestic resource for long-term carbon storage and support ERW as a potential component of India’s decarbonization strategy.
Contrasting slab decarbonation patterns control deep carbon cycling efficiency in hot vs. cold subduction zones
Authors: Hengrui Zhang, Yang Wang, Zhong-Hai Li, Taras V. Gerya et al.
Synopsis: Modeling study compared carbon release in the hot Colombia and cold Tonga subduction zones to better understand deep Earth carbon cycling. The results reveal that hot subduction zones release carbon efficiently over a narrow depth range, whereas cold subduction zones remove carbon much more slowly across greater depths. These contrasting decarbonation patterns improve understanding of volcanic CO₂ emissions and the long-term cycling of carbon between Earth's surface and interior.
Climate benefit and ecological cost trade-offs for ocean iron fertilization
Authors: Jun Yu, J. Keith Moore, Francois W. Primeau, et al.
Synopsis: Using a process-rich ocean biogeochemical model, researchers assessed the climate benefits and ecological risks of ocean iron fertilization (OIF) across ten ocean biomes. They found the Southern Ocean offers the most favorable balance of carbon removal and environmental impacts, while fertilization in the equatorial Pacific causes greater ecological disruption despite similar carbon removal efficiency. The study also shows that much of the captured CO₂ is eventually re-emitted, highlighting challenges for carbon crediting, governance, and large-scale deployment.
Implications of straw removal on soil carbon stocks in German croplands
Authors: Daria Seitz, René Dechow, Mirjam Helfrich & Axel Don
Synopsis: The study evaluates the climate impacts of increasing straw removal from German croplands to supply biomass for replacing fossil-based products. Modeling across 1,115 agricultural sites shows that large-scale additional straw harvesting could reduce soil organic carbon stocks and generate significant CO₂ emissions, potentially offsetting some benefits of fossil fuel substitution. The authors conclude that sustainable residue management, including practices such as cover cropping, is needed to maintain soil carbon and support climate mitigation.
Harnessing cover crop–rock weathering synergies for climate-smart agriculture
Authors: Tianyi Qiu, Jay Ram Lamichhane, David J. Beerling et al.
Synopsis: Authors propose combining cover crops (CCs) with ERW to create more sustainable and climate-resilient agricultural systems. They argue that interactions between plant roots, soil processes, and mineral weathering could improve carbon sequestration, nutrient cycling, greenhouse gas mitigation, and soil health. However, challenges including weathering limits, potential metal accumulation, and governance barriers must be addressed before widespread deployment of CC–ERW approaches.
Proton trap engineered electric swing adsorption for scalable and cost-effective direct air capture
Authors: Yao Shen, Kai Pang, Weichen Zhao, Liang Chen, Jingkai Zhao, Jiexu Ye, Beini Zhang, Sujing Li, Wei Li, Zhen Xu, Jing Meng, Xiang Gao & Shihan Zhang
Synopsis: Researchers developed a new electric swing adsorption (ESA) sorbent for DAC that addresses the traditional limitation of inefficient amine–CO₂ interactions. By creating a proton-trapping network, the material achieves a 1:1 amine-to-CO₂ ratio, increasing CO₂ uptake and reducing regeneration energy. Techno-economic analysis suggests the approach could lower DAC costs to below $100 per tonne of CO₂, offering a potential pathway toward large-scale, low-energy carbon removal.
Revisiting TSA and TVSA for DAC: Operating Windows, Thermodynamic Bounds, and Exergy Efficiency
Authors: Gerhard Hofer, Tobias Pröll
Synopsis: The study develops a thermodynamic model to evaluate continuous temperature–vacuum swing adsorption (TVSA) systems for solid-sorbent DAC under realistic conditions. Results show that lowering desorber pressure can improve regeneration efficiency and reduce heat requirements, while vacuum-enabled regeneration can achieve efficiencies above 30%. The analysis highlights regeneration heat and blower energy as key performance limits, providing guidance for improving sorbents, reactor design, and DAC system efficiency.
Amine-Functionalized Covalent Organic Framework for Direct Air Capture of Carbon Dioxide
Authors: Mohamed Essalhi; Rawan A. Al Qahtani; Aasif Helal; Mona S. Otaibi; Ammar H. Alahmed; Zain H. Yamani; Islam M. A. Mekhemer; Mahmoud M. Abdelnaby
Synopsis: Researchers modified a vinylene-linked covalent organic framework (COF) by adding amine groups to enhance its carbon dioxide capture performance. Although the functionalization reduced surface area, it introduced stronger CO₂-binding sites, improving adsorption capacity, selectivity, and stability under direct air capture conditions. The findings demonstrate that postsynthetic amine modification can transform COFs into efficient low-pressure CO₂ capture materials for future carbon removal applications.

PODCASTS
remove’s new Latin American carbon dioxide removal accelerator program—w/ Hans Westerhof & Marian Krüger | Reversing Climate Change
“There are many startup accelerators out there. There are fewer focused on climate tech. Fewer still for carbon dioxide removal. Lucky for us, remove runs the absolute heck out of their programs. And it’s been a true joy of mine coaching startups in them this past year. I can’t even believe it, but the time has come for another program... In Latin America!
If you are a Latin American carbon dioxide removal project and/or technology developer, you should apply to remove’s LatAm cohort. Applications are out now, and there is a chance we might end up working together.
I have had nothing but wonderful experiences with the team at remove. They offer focused training, a powerful network, and an unmatched peer group in your cohort. Hoping to see you there!
In today’s episode, cofounders and managing directors of remove, Marian Krüger and Hans Westerhof, join the show to talk about the program, what it means to be ecosystem builders, and how they aim to grow capacity in the Global South generally and Latin America in particular.”
The EU ETS Proposal: the Scoop’s Debrief | The CDR Policy Scoop
“In this episode of The CDR Policy Scoop, Eve Tamme and Sebastian Manhart follow up on their interview with Mette Quinn to hash out their own read of Brussels’ proposal to fold carbon removals into the EU ETS, and they don’t agree on much. Is this really a “compliance market,” or a purchasing programme that happens to sit on the ETS cap? Eve and Sebastian take opposing sides, and the answer matters more than semantics: it shapes how the whole mechanism should be judged.
The cost assumptions get the roughest treatment. Sebastian has spent the past week stress-testing the BioCCS and DAC numbers behind the impact assessment, and he’s not convinced. The transport and storage figures look wildly optimistic against what he’s hearing from Europe’s biggest BioCCS developers off the record. Biochar comes off worse still: favourably discussed in the impact assessment, then dropped entirely from the actual proposal, with nature-based solutions getting an explicit review clause that biochar never received.
Timing is the other flashpoint. A 250 million ton removals commitment sounds decisive, until you line it up against a 48 million ton auctioning target for 2039 and realise the years don’t match. Add in unresolved questions about who eats the risk on non-delivered offtakes or a shifting carbon price, and the “who pays” question stops being hypothetical.
They close on supply: will a demand signal alone be enough to pull removals out of the Global South, or will an undersupplied market let developers simply triage toward whoever pays most? Robert Höglund’s observation that this may be the first major EU proposal to treat permanent removals as functionally equivalent to reductions gets a nod too, a precedent Eve and Sebastian both think could ripple well beyond the ETS.”
Inside the Framework for Residual Emissions - with Injy Johnstone | The CDR Policy Scoop
“In this episode of The CDR Policy Scoop, Eve Tamme and Sebastian Manhart sit down with Dr. Injy Johnstone, Senior Research Fellow at the Max Planck Net Zero Lab, to unpack her new report, What Are Residual Emissions, which tries to bring clarity to one of climate policy’s most used and least defined terms.
Johnstone explains why, more than a decade after the term entered use, there is still no shared definition. The IPCC modeling community that coined it works from different inputs than a corporate net zero team, and the timeline question, today’s technology versus a 2050 horizon, changes the answer. She also draws a distinction the sector often blurs: hard to abate describes a technological limit, while residual emissions is a broader, more normative category shaped by choices about demand reduction and regulation.
The conversation turns practical as Johnstone breaks residual emissions into near, medium and long term buckets that corporates and governments can plan against. Sebastian presses on the middle bucket, where overly optimistic assumptions about future technology can quietly reduce carbon removal investment today. Johnstone and Eve also test the new SBTi and ISO standards released since the report’s publication.
They close on equity: who decides an industry keeps its social license to keep emitting, and who absorbs the trade offs within a finite carbon budget. Johnstone argues these normative choices are already being made, whether admitted or not, and surfacing them is the first step toward distributing that cost fairly.”

What are residual emissions? On Scrubbing the Skies | Institute for Responsible Carbon Removal
“This webinar - What are residual emissions? A science-based understanding to underpin corporate carbon accounting guidance - presents findings from a new report that provides a science-based examination of the concept of residual emissions, highlighting that no single authoritative definition exists across academic literature, national strategies or corporate standards. Residual emissions are best understood not as a fixed category but as the emissions that remain at the net-zero balance point after all technically, economically and socially feasible abatement has occurred. However, what is “feasible” is inherently subjective and evolves over time. Because residual emissions are shaped by assumptions in integrated assessment models, sector-specific constraints, and broader social and political choices, corporates require a dynamic, time-bound and technology-conditional approach. The report proposes a practical framework for companies to classify emissions by abatement timeframe, plan and disclose their pathways, and develop robust carbon removal strategies to neutralise remaining emissions, ensuring transparent, credible and adaptable net-zero planning.”

CDR and Carbon Politics: The View from the Humanities | CanCO2Re Initiative
“Carbon Dioxide Removal is not just about designing new technologies, but also a subject of politics, especially upon implementation when citizens are asked to accept these new technologies. CDR features in both the past and present of climate politics in complex, even contradictory ways. And because it can be deployed strategically and discursively by actors with varied intentions and interests, CDR brings with it a host of social and political considerations.
In this webinar, Dr. Petra Dolata and Dr. Mack Penner talked about the relationship between CDR and the politics of climate change. Using both historical examples and theoretical insight, they discussed how the humanities offer a disciplinary vantage from which CDR can, and indeed must, be understood if it is to serve its purpose in reducing carbon emissions and slowing the climate crisis.”
