THIS WEEK’S TOP CDR HIGHLIGHTS
PAPER ON CO2 STORAGE CAPCITY: A new study sets a planetary limit of ~1,460 Gt CO₂ for geological storage, warning capacity is finite and only sharp near-term cuts can prevent breaching it before 2200, with storage capping cooling at ~0.7°C. However, industry experts like Jack Andreasen argue the estimate overlooks mineral storage in basalt and peridotite, which could provide far greater, more durable capacity through mineral carbonation.
CDR COMPETITION: The OpenAir Collective announced to launch the 2026 Carbon Removal Challenge on September 18, inviting university students worldwide to design innovative solutions for removing CO₂ from air, land, or water.
UNIVERSITY-LED FIRST ONLINE CDR COURSE: Heriot-Watt University has launched Carbon Dioxide Removal from a Systems Perspective – the world’s first university-delivered online course dedicated to carbon removal.
BIOCHAR STATISTICS: The industrial biochar market is tightening rapidly as 89% (nearly nine out of ten) of 2025 carbon removal credits are already sold out, up from 62% in March, according to Supercritical. Prices are also rising and high-quality credits are commanding a 10–20% premium.
NEW INITIATIVE: Octavia Carbon, with atmosfair gGmbH, has launched an ‘Adopt a DAC Machine’ model. The scheme lets buyers fund new Direct Air Capture units while securing multi-year carbon credit allocations, aiming to speed up deployment of durable carbon removal.
REPORT: Tokyo-based Exroad, in partnership with CDR.fyi, has released a report providing a comprehensive review of the carbon removal landscape, covering policy, pricing, certification, SBTi alignment, and both domestic and international trends.
MULTI-FUEL LIMESTONE KILN WITH DAC: Origen has commissioned a seven-story tall kiln with integrated direct air capture technology to decarbonize lime production at the EERC in North Dakota. The facility can cut over 2,000 tCO₂ annually.

RESEARCH PAPERS
The Reversibility of Antarctic Sea Ice Loss Under CO2 Removal Scenarios
Authors: Sirui Li, Kaiming Hu, Gang Huang, Xiao-Tong Zheng
Synopsis: This study examines whether Antarctic sea ice loss since 2014 can be reversed through CDR. Using CMIP6 experiments, it finds large model differences linked to initial ocean stratification. Strong stratification traps heat in surface waters, accelerates melting, and reinforces feedbacks that hinder recovery. Weaker stratification allows deeper heat storage, supporting ice regrowth. Results show initial stratification critically shapes the reversibility of Antarctic sea ice under CDR scenarios.
Unlocking BECCS viability through monetizing societal benefits by techno-socio-economic assessment
Authors: Alberto Almena, Vahid Ghorbani Pashakolaie, Mariano Martin
Synopsis: This study introduces a Techno-Socio-Economic Assessment (TSEA) for BECCS, integrating societal benefits like emission displacement and job creation via social cost of carbon and labour valuation. A wheat-straw BECCS case shows negative returns under conventional TEA (NPV −$460M), requiring >$240/tCO₂ credits. Under TSEA, all modes are profitable, with electricity-maximizing reaching $2.28B NPV. Results highlight BECCS viability depends on valuing full societal benefits and supportive policy design.
Techno-Economic Assessment of Hybrid Renewable Energy Systems for Direct Air Capture in Saudi Arabia
Authors: Sana Aljishi, Sarah Alyami, Eman Alghorabi, Hana Faltakh, Hamid Zentou, Mahmoud Abdelnaby, Nouf K. AL-Saleem, G. I. Ameereh and Fawziah Alhajri
Synopsis: This paper evaluates pathways for deploying DAC to support Saudi Arabia’s Vision 2030 net-zero target. Using HOMER Pro, it assesses renewable energy configurations across regions to optimize Net Present Cost (NPC) and Levelized Cost of Energy (LCOE). Results highlight DAC’s potential when powered by renewables rather than fossil fuels, though costs remain high. The study identifies cost-effective deployment strategies to make DAC a viable contributor to the Kingdom’s 2060 climate goal.
Oyster farming acts as a marine carbon dioxide removal (mCDR) hotspot for climate change mitigation
Authors: Xue-Wei-Jie Chen, Zhou Zhang, Miao-Jun Pan, et al.
Synopsis: Field mesocosm experiments show oyster farming boosts marine CDR by enhancing organic carbon production and sediment deposition, shifting waters toward autotrophy and alkalinity. Net sequestration from oyster-driven carbon is 2.39× higher than shell storage. This positions bivalve farming as a scalable, nature-based climate solution with co-benefits for food security and ocean health.
Scenario Storylines for Carbon Dioxide Removal in Germany: Drawing From Regional Perspectives
Authors: Ronja Wollnik, Nora Szarka, Nils Matzner, Danny Otto, Mohammad Sadr, Danial Esmaeili Aliabadi, Raphael Tremmel, Joshua Röbisch, Daniela Thrän
Synopsis: Germany views CDR as essential to its 2045 climate neutrality goal, complementing emissions cuts. This study explores bio-based CDR—BECCS, natural sinks, and biomass construction—via scenarios shaped by policy, social, economic, and environmental drivers. Using the PESTEL framework plus biomass, four storylines emerge: cost-efficiency, decentralized/nature-based focus, large-scale “skyrocketing,” and limited “roadblock.” These guide modeling, strategies, and value chain design.
A prudent planetary limit for geologic carbon storage
Authors: Matthew J. Gidden, Siddharth Joshi, John J. Armitage, Alina-Berenice Christ, Miranda Boettcher, Elina Brutschin, Alexandre C. Köberle, Keywan Riahi, Hans Joachim Schellnhuber, Carl-Friedrich Schleussner & Joeri Rogelj
Synopsis: This study finds that geological CO₂ storage is vital but finite, with a prudent planetary limit of ~1,460 Gt (1,290–2,710). Only sharp near-term emission cuts can prevent breaching it before 2200. At full use, storage could reduce warming by just 0.7 °C. Major fossil-fuel extractors show strongest robustness. Treating storage as a scarce, intergenerational resource has major policy and mitigation implications.
The six-year decomposition of coarse woody debris drives shifts in soil fungal communities in subtropical forests
Authors: Nan Wang, Binle Ding, Hui Chen, Tingsi Xie, Shangbin Bai, Hua Chen, Xiaocheng Pan
Synopsis: This six-year field experiment (2018–2024) in a subtropical evergreen forest in China found that coarse woody debris (CWD) decomposition increased soil organic, dissolved, and microbial carbon, while lowering pH. Bamboo CWD promoted the highest carbon gains. Sequencing showed higher fungal α-diversity, distinct β-diversity, and shifts toward Basidiomycota and saprotrophs. Soil pH and SOC shaped community assembly, highlighting CWD’s role in fungal diversity and carbon stability.
Solar Geoengineering Likely up to 14 Times More Efficient than CDR: Albedo Misrepresentations in Climate Forcing and Governance - Preprint
Authors: Alec Feinberg
Synopsis: This study proposes an Unsaturated Linear Forcing (ULF) model, assigning equal forcing potential to each added GHG unit. Unlike IPCC’s logarithmic formulas, ULF gives ~39% lower total forcing since 1750 and ~11% lower for CO₂ doubling, revealing diagnostic gaps. Results show solar geoengineering (SG) could be ~12–14× more efficient than CDR, with Earth responding more strongly to albedo than GHG changes. The analysis highlights a global albedo crisis driven by declining reflectivity and urban darkening, calling for SG as a premier mitigation tool. A sustained annual strategy—combining surface brightening, sunshades, and stratospheric aerosol injection, especially in polar regions—is recommended for urgent, high-leverage climate response.
The role of BECCS in Germany: a key to sustainable and permanent CO2 removal?
Authors: Daniela Thrän, Malgorzata Borchers, Volker Lenz, Matthias Jordan, Till Markus, Nils Matzner, Katja Oehmichen, Danny Otto, Kai Sven Radtke, Nir Reshef
Synopsis: This study of Germany’s bioenergy system found >25 Mt CO₂/yr could be captured via BECCS using biogenic waste and residues. High-potential sites include waste incineration and biomass CHP plants. Deployment depends on costs, technology, legal frameworks, and social acceptance. Combining BECCS with peatland rewetting, cascade biomass use, and hard-to-abate sectors enhances compatibility, while secure investment and CO₂ infrastructure are key to scaling.
Electrically Conductive Amine-Functionalized Adsorbents Driven by Joule Heating for Direct Air Capture
Authors: Shu Zhao, Yiran Zhang, Yirui Ning, Linjia Li, Junfeng Lu, Xiaochao Wang, Fudong Wang, Zhidong Wei, Zhen Huang, He Lin
Synopsis: This study introduces a self-conductive amine-functionalized adsorbent for DAC that uses direct Joule heating to cut regeneration energy demand. The optimized adsorbent (Ad-0.48PE/0.32HP/0.20CB) achieved 2.4 mmol/g CO₂ uptake, rapid 120 s desorption, and low energy use (3.5–3.7 GJ/t CO₂). A solar-powered prototype validated fast, repeatable cycles, highlighting its promise for renewable, scalable DAC applications.
Investigation of Technical Issues for Adsorbent-Based Electrochemical Marine Carbon Dioxide Removal
Authors: Hiroshi Yoshida; Keiichi Yano; Yusuke Ura; Keisuke Kojima; Kengo Tomita; Heng Li
Synopsis: This paper highlights Japan’s climate risks from storms, rains, and wildfires, stressing the need for both emission cuts and CDR. It reviews CDR methods, focusing on CO₂ capture from seawater via electrodialysis. A proposed system could meet Japan’s CO₂ removal needs, but scaling—mainly from magnesium hydroxide—poses a key challenge. Two mitigation strategies are suggested to reduce scaling, advancing the feasibility of large-scale seawater-based CDR.
Carbon drawdown by algal blooms during Antarctic Cold Reversal from sedimentary ancient DNA
Authors: Josefine Friederike Weiß, Ulrike Herzschuh, Juliane Müller, Jie Liang, Maria-Elena Vorrath, Amedea Perfumo & Kathleen R. Stoof-Leichsenring
Synopsis: Ancient DNA from Southern Ocean sediments reveals that during the Antarctic Cold Reversal (14,700–12,700 yr BP), the haptophyte Phaeocystis antarctica dominated primary production, driving high productivity linked to enhanced sea-ice seasonality. After the event, abrupt Phaeocystis decline underscored ecosystem sensitivity to warming. This suggests regions like the Ross Sea, with strong seasonal sea ice and Phaeocystis blooms, are crucial for stabilizing atmospheric CO₂ under present climate change.
The effect of ocean alkalinity enhancement on zooplankton standing stock and community composition in the Eastern Mediterranean Sea: a mesocosm study
Authors: Ariadna C. Nocera, Claudia Traboni, Justine Courboulèsz, Filomena Romano, et al.
Synopsis: This 14-day mesocosm study in the Eastern Mediterranean tested ocean liming (OAE with Ca(OH)₂) impacts on zooplankton. Communities, dominated by Tintinnina and Copepoda, showed complex but subtle shifts, with nauplii far outnumbering adults. pH, nutrients, and temperature explained more variation than lime treatments, suggesting short-term resilience. Results highlight the need for long-term studies on OL’s ecological effects, nutrient dynamics, and food-web interactions before large-scale deployment.
Enhanced Carbon Sequestration Performance and Mechanism of Adsorption-Catalytic Bifunctional ZIF-8 Coupled Microalgae
Authors: Luna Wang, Yan Gong, Yanming Miao Zhifeng Zhang
Synopsis: This study developed bifunctional ZIF-8-based nanozymes (ZNZs) with CO₂ adsorption and carbonic anhydrase–mimetic activity to boost microalgae performance. At 5 mg/L, ZNZs increased growth by 7%, chlorophyll by 12.6%, and carbohydrates by 4.2%. Rubisco and CA activity rose up to 21.3%, 10%, and 8.3%. Results show ZNZs enhance photosynthesis and CO₂ uptake, offering a promising strategy for carbon capture and sustainable bioenergy production.
Genotypic Differences in Soil Carbon Stocks Under Miscanthus: Implications for Carbon Sequestration and Plant Breeding
Authors: Amanda J. Holder, Rebecca Wilson, Jeanette Whitaker, Paul Robson
Synopsis: This study examined soil organic carbon (SOC) changes after converting UK grass pasture to Miscanthus in a 10-year field trial. SOC stocks recovered to pre-conversion levels (82 vs 79 Mg C ha⁻¹, 0–30 cm), but varied widely between genotypes (32 Mg C ha⁻¹ difference). Traits such as large rhizome mass and leaf litter boosted SOC. Results show genotype strongly influences SOC sequestration, indicating Miscanthus breeding can target both high yield and soil carbon gains for climate mitigation.
The Impact of Different Injection Strategies on Fluid Migration and Formation Safety in CO2 Saline Aquifer Sequestration
Authors: Yanghui Li, Qingyong Lu, Peng Wu
Synopsis: A THMC model for CO₂ storage in Xinjiang’s Tarim Basin shows how injection strategies affect capacity and stability. High rates trigger stress rises (~30%) and uneven migration, while gradient-accelerated injection reduces leakage risks by ~9% and sustains ~17 Mt/km³ density. Decade-long simulations reveal irreversible deformation (0.25 m subsidence, 0.05 m uplift), raising caprock and fault risks. Results guide safer, optimized saline aquifer storage.

The Science of Climate Engineering: Risks and Benefits
Authors: G Mwende Wairimu
Synopssi: This thesis reviews climate engineering, tracing its history, mechanisms, benefits, and risks. It distinguishes SRM—fast, low-cost, but risky—from CDR—slower, costlier, but less hazardous. Beyond science, public perception, ethics, and international law complicate deployment. The study stresses strong governance, transparent research, and global collaboration to ensure safety and equity. It concludes that geoengineering may complement mitigation and adaptation, but only under strict safeguards.
Advancing Direct Air Capture via Wood-Derived Biochar: Catalytic Enhancement of CO2 Adsorption Performance and Regeneration Stability
Authors: Eshita, Jannatul Adnin
Synopsis: This thesis finds that wood-derived biochar shows strong potential as a low-cost DAC sorbent. In fixed-bed tests with 400 ppm CO₂, it achieved up to 91.8% removal at 5 °C and low flow rates, with total capacity of 0.055 mmol/g after 12 h. Adsorption followed both physisorption and chemisorption. The material remained stable over regeneration cycles, underscoring biochar’s promise for scalable, renewable CO₂ capture under varied conditions.
