THIS WEEK’S TOP CDR HIGHLIGHTS
RESEARCH PAPER: In a new peer-reviewed techno-economic analysis, Iowa State researchers found that costs for biomass-fed modular fast pyrolysis units with permanent bio-oil sequestration (Charm Industrial’s process) could fall below $200 per ton removed, with potential for sub-$100 pricing as well. Read Charm Industrial’s blog post and listen to the discussion on this paper here.
TECHNICAL BRIEF: To inform EU policy on carbon removals, Sandbag released a technical brief that uses a new ETS + CDR simulator to assess the risks of premature integration, highlighting why early inclusion of CDR in the EU ETS could undermine emissions reductions, distort price signals, and over-incentivise unproven technologies.
REPORT: A London School of Economics report found the US is “squandering its competitive edge” in carbon dioxide removal and creating an opening for the UK and Europe.
JOB OPPORTUNITY: The Grantham Research Institute on Climate Change and the Environment at the London School of Economics is looking for a Research Officer to work on economic, legal, and political challenges surrounding the integration of carbon dioxide removal methods into compliance carbon markets (e.g. The UK and EU ETS), focusing on developing new scenario based empirical modelling and tools. Deadline to apply: 27 July 2025.
FUNDING OPPORTUNITY: Remove launched India CDR accelerator applications for early-stage startups (apply by August 20).
MARKET SNAPSHOT: According to ClimeFi, Q2 2025 saw durable CDR commitments surge from 13.5 MtCO₂ to 29.2 MtCO₂, with buyers spending $3.9 billion. Microsoft led with 22.7 MtCO₂ (76% share). Despite an 85% drop in issuance, verified removals spanned DACCS, Bio-Oil, Marine, and Mineralisation.
THESIS: A recent thesis by Luna Geerts assessed olivine-based marine enhanced rock weathering (mERW’s) feasibility, finding it cost-effective if fast dissolution is maintained, but its overall CO₂ removal potential is lower than hoped. Sediment conditions strongly affect performance. Gigaton-scale mERW isn’t feasible, but targeted local use can still contribute meaningfully.
PREMIUM CDR CREDITS: TREEO and biometrio.earth launched the 'world's first premium carbon removal credits' that combine data-driven single-tree monitoring with cutting-edge biodiversity analytics.

RESEARCH PAPERS
Acidity addition in the Mississippi watershed drives agricultural CO2 emissions
Authors: Tim Jesper Suhrhoff, Chris Reinhard, Yoshiki Kanzaki, Shou-En Tsao, Beck Woollen, Tom Reershemius, et al.
Synopsis: This study challenges the view that agricultural liming is a CO₂ source, arguing instead that adding limestone to acidified soils can act as CDR compared to the counterfactual of acidity-driven emissions. Data from the Mississippi River catchment show liming has been a net CO₂ sink for over a century. The findings suggest acid-base reactions release more CO₂ than assumed and that enhanced carbonate weathering could be a more efficient CDR pathway than silicates, calling for updated soil pH management policies.
Future Scenarios of Global Fisheries and Ocean Alkalinity Enhancement Under Socio-Economic and Climate Pathways
Authors: Hans Sloterdijk, Caroline Grünhagen, Rudi Voss, Patricia Grasse, David P. Keller, Linda Kleemann, et al.
Synopsis: Achieving climate goals while protecting food security is challenging with land-based solutions alone. Ocean alkalinity enhancement (OAE) could boost the ocean’s carbon sink and cut CO₂, but its effects on fisheries are unclear. This study explores how OAE and global fisheries interact under three scenarios: sustainable (SSP1-2.6), fragmented (SSP3-7.0), and high-emission (SSP5-8.5). Findings show sustainability pathways best support coexistence. Success depends on tech progress, global cooperation, and strong fisheries management.
Stability of alkalinity in the land-ocean transition zone: a geochemical CDR perspective for the Elbe River, Germany
Authors: Mingyang Tian, Jens Hartmann, Niels Suitner, Thorben Amann, Stephan Kempe, Carl Lim and Charly Andre Moras
Synopsis: This study examines the stability of added alkalinity for carbon dioxide removal using Elbe estuary freshwater. Incubation experiments show that alkalinity persistence depends on suspended particles, seasonal water chemistry, and salinity. Results suggest the Elbe could transport enough alkalinity to remove ~3.0 MtCO₂ per year toward the North Sea. However, long-term trends and geochemical limits may reduce this potential. Realistic levels must balance effectiveness with environmental constraints and regulations.
Biomineralising trees turn CO2 into CaCO3? Identifying novel oxalate-carbonate pathways associated with East African Fig trees in Samburu County, Kenya
Authors: Mike C. Rowley et al.
Synopsis: The oxalate-carbonate pathway (OCP) captures CO₂ as CaCO₃ near certain plants, but its use in agroforestry is understudied. This research explores OCP in three East African fig tree species growing on degraded soils in Kenya. All fig species showed CaCO₃ formation, with Ficus wakefieldii producing the most and strongly influencing soil biogeochemistry. CaCO₃ forms both inside and outside the trees via two mechanisms. Fig-based OCP-agroforestry could sequester CO₂ and boost local food security.
Dynamic modeling and optimal control schemes for an offshore-wind powered direct air capture system with energy storage options
Authors: Muhammad Faisal Shehzad, Haris Ishaq, Curran Crawfrod
Synopsis: Direct air capture can reduce atmospheric CO₂ but must avoid fossil fuel use to ensure net removal. This paper proposes an offshore wind-powered DAC system integrated with advanced energy storage (ESS) to handle wind’s variability. Using a dynamic energy management strategy, the model optimizes DAC operation through three states—OFF, Adsorption, and Desorption—each treated as separate loads. Simulations show that flexible scheduling with ESS makes wind-powered DAC feasible year-round, maximizing CO₂ capture while meeting operational limits.
A Membraneless Electrochemically Mediated Amine Regeneration for Carbon Capture
Authors: Ahmad Hassan, Mohsen Afshari & Mim Rahimi
Synopsis: Electrochemical carbon capture (ECC) offers a modular alternative to thermal methods. This study introduces a membraneless electrochemically mediated amine regeneration (EMAR) system using gas diffusion electrodes (GDEs) to cut costs and simplify design. The new setup removes the need for costly ion-selective membranes and extra equipment. Tests show over 90% CO₂ removal with energy use as low as 60 kJ/mol CO₂. Estimated capture costs drop to ~$70/tonne CO₂, with potential for <$50, making it a scalable, cost-effective option.
Enhancing carbon removal via scalable on-site pyrolysis and well-plugging systems
Authors: Pallavi Dubey, Samirah Gnangbe, Mark Mba Wright
Synopsis: The U.S. has vast biomass resources with over 1 billion tons/year potential. This study assesses small-scale, distributed biomass fast pyrolysis as a carbon removal pathway, converting feedstocks like corn stover and switchgrass into bio-oil and biochar for storage. For corn stover, bio-oil costs $175/ton, with a carbon abatement cost of $83.6/ton CO₂ (including biochar). Small-scale systems benefit from economies of numbers and are cost-effective below 6,000 Mt CO₂/year, offering a promising option alongside DAC.
Who pays for carbon dioxide removal? Public perceptions of risk and fairness of enhanced rock weathering in the UK
Authors: Kate O’Sullivan, Nick Pidgeon, Karen Henwood, Fiona Shirani & Harriet Smith
Synopsis: Enhanced rock weathering has high potential for carbon dioxide removal but raises public acceptance concerns due to uncertain costs and impacts. This UK study used five community workshops to explore local views on fair deployment. Acceptance depends on place-sensitive implementation, clear local benefits, transparent governance, robust monitoring, and honest communication. Communities reject ERW if it risks ecosystem harm, lacks remediation plans, or enables false carbon accounting. Integrating local perspectives is vital for fair, effective governance.
Site selection for ocean alkalinity enhancement informed by passive tracer simulations
Authors: Yiming Guo, Ke Chen, Adam V. Subhas, Jennie E. Rheuban, Zhaohui Aleck Wang, et al.
Synopsis: Ocean alkalinity enhancement adds alkaline material to boost ocean carbon uptake, but its effectiveness depends on ocean circulation. This study used passive tracer simulations (2009–2017) to assess when and where to deploy OAE on the U.S. Northeast Shelf. Results show strong seasonality: summer offers better dilution and retention than winter. Wilkinson Basin ranked best for tracer dispersal due to its wide spread, higher concentrations, and longer retention. These insights guide future OAE field tests and site selection elsewhere.

Influence of Wave-Induced Variability on Ocean Carbon Uptake
Authors: P. Rustogi, L. Resplandy, E. Liao, B. G. Reichl, L. Deike
Synopsis: This study shows that high-frequency wind and wave variability significantly affects air-sea CO₂ fluxes by altering gas transfer velocities. Using a wind-wave-bubble formulation in an ocean model, results reveal CO₂ flux changes of +15–40% seasonally and locally up to 50% during storms. This boosts ocean carbon storage by ~0.07 PgC/year (~3%), with greater storage in the Southern Hemisphere’s active wave regions. Accounting for wave effects is vital to accurately model local and seasonal carbon dynamics and assess marine carbon removal.
Advancing geothermal energy utilization opportunities: potential and strategies for integrating direct air capture
Authors: Maxwell Pisciotta, Hélène Pilorgéa, Likhwa Ndlovua, Madeleine Siegelb, et al.
Synopsis: Geothermal energy, long used for baths and heating, now provides low-carbon electricity and direct heat. Beyond power, geothermal can help remove CO₂ by supplying heat and power to direct air capture (DAC) systems. This study developed a framework to assess geothermal-DAC integration, testing it on low- and high-temperature resources and a real plant. Results show integrating geothermal with DAC boosts CO₂ abatement by 5–757% over electricity-only use. Levelized CO₂ capture costs range widely ($101–$8579/tCO₂), highlighting the need for careful design to maximize CO₂ removal and grid benefits.
Removal of dissolved inorganic carbon from seawater for climate change mitigation – understanding the potential marine ecosystem impacts
Authors: Guy Hooper, Helen S Findlay, Thomas George Bell, Rod W Wilson, Paul Halloran
Synopsis: Electrochemical Direct Ocean Carbon Capture and Storage (DOCCS) removes CO₂ by releasing low-DIC, high-pH seawater that re-equilibrates with the atmosphere. While it can help store atmospheric CO₂, its discharge may impact marine ecosystems, but no direct studies exist yet. Insights from related research highlight potential effects, yet major evidence gaps remain. Addressing these gaps is vital for licensing, mitigation, assessing net benefits, and informing public debate on the viability of marine carbon removal.
Prevalence of multi-micronutrient limitation of phytoplankton growth in the Southern Ocean
Authors: Willy Baeyens, Yue Gao, David J. Janssen, Andrew R. Bowie, Chunyang Zhou, Gaojing Fan
Synopsis: To help mitigate global warming, boosting phytoplankton biomass can remove more CO₂ from the atmosphere. In the Southern Ocean, iron (Fe) is known to limit growth, but this study finds cobalt (Co), zinc (Zn), and silicon (Si) can also be limiting nutrients. Modeling shows Fe and Co limit growth across the sub-Antarctic and Antarctic zones, while Zn and Si limit growth mainly in the SAZ. Thus, large-scale ocean fertilization would need multiple micronutrients to effectively enhance carbon capture.
Improvement of mechanical properties and carbon sequestration effect of carbide slag-carbonization curing on cement-based materials
Authors: Dao-Lin Sun, Yonghong Miao, Jianguo Zhu, Peng Wang, Yulong Zheng, Kaiwei Lu, Gui-Yu Zhang
Synopsis: The construction industry emits high CO₂ levels. This study shows that partially replacing cement clinker with calcium carbide slag (CCS) and using carbonation curing can cut emissions and recycle waste. Adding CCS lowers strength, but 5% CCS with carbonation curing boosts 28-day compressive strength by 18%. CCS increases CO₂ absorption, reaching 25.91% at 20% CCS. Microscopy reveals calcite fills voids, enhancing structure, though excess causes cracks. Proper CCS use improves strength and carbon fixation.

THESIS
Feasibility of carbon dioxide removal in marine systems using enhanced rock weathering with olivine
Authors: Luna Geerts
Synopsis: Limiting warming to below 2 °C needs CO₂ removal alongside emission cuts. Marine enhanced rock weathering (mERW) accelerates natural silicate weathering to boost ocean alkalinity and CO₂ uptake while curbing acidification. This thesis assessed olivine-based mERW’s feasibility, finding it cost-effective if fast dissolution is maintained, but its overall CO₂ removal potential is lower than hoped. Sediment conditions strongly affect performance. Gigaton-scale mERW isn’t feasible, but targeted local use can still contribute meaningfully.

Turbo-charging the natural carbon cycle | RAZOR Science Show
"Stefano Capello and his company Limenet, who have developed an innovative approach to tackle both carbon emissions and ocean acidification simultaneously. Working from Sicily's industrial coastline – ironically nicknamed the "Triangle of Death" due to heavy petrochemical pollution – they're pioneering a technology that accelerates nature's own carbon capture process.
Their breakthrough centers on limestone, one of Earth's most abundant materials. In nature, geological carbon cycling slowly captures CO2 over millions of years as carbonic acid breaks down rocks, releasing bicarbonate and calcium ions that eventually reach the ocean and lock carbon away for millennia.Limenet has found a way to turbocharge this process from thousands of years to just four minutes.
Currently, Limenet's temporary plant at Sicily's Port of Augusta captures 800 tons of CO2 annually – admittedly "a drop in the ocean" compared to the 20 billion tons we need to capture yearly to reverse climate change. "
