THIS WEEK’S TOP CDR HIGHLIGHTS

Request for Proposals: Watershed has opened its 2026 carbon removal RFP, inviting developers to supply credits for its network of 800+ global companies, including 90 of the Fortune 500. The RFP focuses on durable removal, nature-based solutions, and superpollutant avoidance, with a goal to fill demand for high-quality, verified credits. Applications are open until April 10, 2026. On March 19th, Watershed will be sharing lessons from their first RFP in a webinar focused on trends in carbon markets.

Frontier’s 2026 Carbon Removal Innovation Program: Frontier has opened its 2026 Carbon Removal Innovation Program, inviting innovators to apply for prepurchases (~US $250K-$1.5M) and R&D grants (~US $250K-$750K) to tackle key carbon removal bottlenecks. The call under Frontier’s US $1B+ advance market commitment seeks solutions to improve mineralization, ocean and inland alkalinity enhancement, and MRV tools.

Combining Superpollutant Abatement with CDR: Carbon Direct released a comprehensive, first-of-its-kind report providing corporations with a roadmap for combining superpollutant abatement, including methane reduction, with durable CDR. The framework enables companies and other entities to achieve both immediate and long-term climate benefits by strategically pairing technologies that work across different timescales.

Spain’s CDR Potential: A new Carbon Removal Readiness Assessment report and roadmap from Carbon Gap and Global Factor finds Spain has significant CDR potential. By leveraging a wide range of CDR methods, Spain could remove up to 69 Mt CO2 annually on top of the country’s natural sink – more than double Spain’s target of reducing emissions to 29 Mt CO2 per year by 2050. But, the report urges stronger policy, infrastructure, and investment is required to scale CDR and support Spain’s climate goals.

Canada Launches CDR Procurement Program: The Government of Canada launched a call for bids to enable the federal departments to purchase at least $10 million CAD of durable carbon dioxide removal credits from projects in Canada, covering DACCS, BECCS, biochar, other biomass CDR, and enhanced mineralization. This makes Canada the “first national government” to launch a dedicated carbon removal procurement program. Deadline: 11 May 2026

Sublime Cuts Staff After Grant Loss: A Massachusetts green‑cement startup, Sublime Systems, has cut about two‑thirds of its staff after the Trump administration rescinded an $87 million federal grant, undermining plans to construct a cement manufacturing plant in Holyoke, and threatening a deal to supply low‑carbon cement to major buyers, including Microsoft.

Undaunted Opens CDR Accelerator Applications: Undaunted, a partnership between Imperial College London and the Royal Institution, has opened applications for the second cohort of its CDR Accelerator, supporting greenhouse gas removal (GGR/CDR) startups in scaling from lab to market. Cohort 2 is scheduled to run from May to October 2026. Applications close 19 April 2026.

RESEARCH PAPERS

A global analysis of expected revenues from carbon dioxide removal
Authors: Alyssa Kozian, Jakob Ellensohn, Tobias S Schmidt and Bjarne Steffen
Synopsis: This study examines expected revenue streams for CDR companies based on 50 interviews with senior leaders across 17 countries. In 2024, voluntary carbon markets dominate, but compliance markets are expected to become the primary revenue source by 2030, especially via cap-and-trade systems. Direct subsidies mainly support immature technologies. Findings highlight that understanding revenue expectations across CDR types and regions can inform policy mixes to effectively promote investment and rapid industry scale-up.
Choosing the appropriate methodology to monitor soil organic carbon (SOC) in croplands: aligning methods with evolving monitoring reporting verification (MRV) frameworks
Authors: Ainhoa Ihasusta, Ahmad Al Bitar, Niels H. Batjes, Fenny van Egmond et al.
Synopsis: This study reviews soil organic carbon (SOC) monitoring methods for croplands and proposes a decision tree to guide MRV stakeholders in selecting appropriate strategies. No single approach fits all contexts; the study recommends measure–remeasure or parsimonious Tier 3 models combined with remote sensing for cost-effective, scalable, and accurate SOC assessment. Assimilating biomass or proxy data improves model performance. The study also identifies current methodological limitations and key challenges for enhancing SOC monitoring frameworks.
Expert elicitation on agricultural enhanced weathering reveals carbon dioxide removal potential and uncertainties in loss pathways
Authors: Brian Buma, Christiana Dietzen, Doria R. Gordon, Kate Maher, et al.
Synopsis: This study evaluates enhanced weathering in agriculture as a CDR strategy using expert elicitation. Global potential estimates for six feedstocks average 0.2–0.7 Gt CO₂e/yr, with some experts suggesting >5 Gt CO₂e/yr. In the U.S. Midwest, removal efficiency ranges 27–39%, with key uncertainties in feedstock availability, calcite saturation, and soil/freshwater emissions. While broad-scale CDR potential appears strong, further empirical research is needed to accurately quantify realized carbon removals.
Upcycling Wood Waste into Solar-Driven Regenerative Sorbent for Direct Air Capture
Authors: Man QiBo Pang, Aji P. Mathew, Zoltán Bacsik, Niklas Hedin, Jiayin Yuan
Synopsis: This study develops a DAC adsorbent by upcycling wood waste, preserving lignin to enable solar-driven CO2 release without added photothermal materials. The adsorbent captures 1.84 mmol/g CO2 at 25 °C, reaching 50% capacity in 7 min and releasing 50% under solar heating at 67 °C in 22 min. Water vapor enhances adsorption, making it effective in humid conditions. This approach offers a sustainable, energy-efficient pathway for DAC using waste biomass.
Towards “set-in-stone” co-deployment of enhanced rock weathering and biochar: an experimental study on their CO2 removal and agronomic co-benefits
Authors: Emily E.E.M. te Pas
Synopsis: This study evaluates Enhanced Rock Weathering and biochar co-deployment for CDR and agronomic benefits. Soil column and greenhouse experiments show wollastonite has high CDR potential, while olivine is limited by nickel release. Biochar reduces trace metal risks, and field lysimeters reveal ERW increases soil pH as a key agronomic benefit. Although ERW offers substantial CDR potential, soil retardation limits actual sequestration, highlighting trade-offs in practical deployment.
Direct air capture enabled by low-grade thermal energy via hot water regeneration of a ligand-exchange sorbent
Authors: Hao Chen, Xinkai Wu, Haibo Liu, Hang Dong, Arup K. SenGupta
Synopsis: This study presents a liquid-phase DAC regeneration method using a hybrid polymeric ligand exchanger (Poly-LigEx-Cu²⁺) that captures CO₂ as bicarbonate. Operable with low-grade hot water (~80 °C) at ambient pressure, the sorbent maintained >90% efficiency over 600 cycles with minimal capacity loss. The process avoids vacuum, inert gases, or dehydration cycles, achieving an energy demand of ~1.4 MWh/ton CO₂. This approach enables scalable, energy-efficient DAC using underutilized industrial waste heat.
The future of direct air capture in Canada: A systematic scenario-based exploration of barriers and possibilities
Authors: Kasra Motlaghzadeh, Vanessa Schweizer
Synopsis: This study examines the socio-political conditions affecting DAC deployment in Canada using the cross-impact balances (CIB) scenario method. Ten key factors—including costs, public perception, clean electricity availability, and interjurisdictional policy—were evaluated by 27 experts, producing 15 internally consistent scenarios. Findings show DAC competitiveness depends on overcoming cost barriers, societal opposition, and policy coherence. The study highlights that both global trends and domestic governance shape DAC feasibility, emphasizing the importance of integrating qualitative socio-political factors in deployment planning.
Acid leaching process of an ultramafic mine tailing for indirect CO2 mineralization
Authors: Kyoung Hun Choi, Spencer Cunningham, Hamid Radfarnia, Kourosh Zanganeh & Gisele Azimi
Synopsis: This study evaluates acid leaching of ultramafic nickel tailings for indirect CO₂ mineralization, comparing hydrochloric acid (HCl) and citric acid. HCl showed higher metal extraction efficiency, especially for Mg and Fe, due to strong dissociation, while citric acid offered moderate, environmentally friendly leaching. Leaching efficiency decreased with higher solid-to-liquid ratios, and temperature effects varied: HCl efficiency sometimes declined at higher temperatures, whereas citric acid performance improved for metals forming stable complexes. Findings inform optimized leaching for sustainable CO₂ sequestration.
Intensified direct air capture of CO2 by integrating a tailor-made water-lean absorbent with high-gravity technology
Authors: Zexiang Gao, Kerui Li, Wangxin Jian, Hao Qin, Youzhi Liu, Weizhou Jiao
Synopsis: This study presents an innovative DAC strategy combining a high-performance water-lean absorbent (MEA–ethylene glycol–water) with high-gravity technology in a rotating packed bed. The approach boosts CO₂ absorption nearly fourfold compared to conventional methods while lowering regeneration energy. Mechanistic analysis shows CO₂ reacts chemically with MEA and interacts via van der Waals forces with EG. This integrated system offers a scalable, energy-efficient pathway for industrial DAC deployment.
Harnessing naturally occurring sodium carbonate and bicarbonate for gigatonne-scale carbon dioxide removal Harnessing naturally occurring sodium carbonate and bicarbonate for gigatonne-scale carbon dioxide removal
Authors: James Campbell, Spyros Foteinis, Reinaldo Juan Lee Pereira, Mohamad Katish, Phil Renforth
Synopsis: This study explores naturally occurring sodium (bi)carbonates as a feedstock for ocean alkalinity enhancement (OAE) for carbon dioxide removal. Mapping 109 global deposits (>200 Gt), dominated by trona and nahcolite, the study evaluates three trona-based OAE pathways: direct dispersal, calcination with CCS, and soda-ash purification. Life cycle assessment of the Green River, Wyoming case shows all pathways are net carbon-negative (29–41% carbon penalties), with calcination plus CCS achieving the highest CDR efficiency (0.21 tCO₂ t⁻¹). Findings highlight sodium (bi)carbonates as a safe, scalable, and promising OAE resource.
Scale-Bridging Solid Adsorbents for Direct Air Capture: Integrating Material Chemistry, Structured Contactors, and Advanced Regeneration Processes
Authors: Injun Park, Sieun Kim, Karoline L Hebisch, Inhwan Park, Minhyung Lee, and Dong-Yeun Koh
Synopsis: This review examines solid adsorbent DAC as a scalable, emissions-independent pathway to net-zero. Highlighting advantages over solvent-based systems—material versatility, modularity, and simpler equipment—it emphasizes the need for holistic, system-level co-optimization across adsorbent selection, structured contactor design, regeneration methods, and techno-economic/environmental assessments. By integrating recent advances, the study outlines a strategic roadmap to accelerate the commercial deployment of efficient, solid adsorbent DAC technologies.
Fine‐Scale Estimation of Urban Biogenic CO2 Fluxes: A Novel Framework Integrating Multiple Versions of Vegetation Photosynthesis and Respiration Models and In Situ Measurements
Authors: Junwei Li , Jia Chen, Theo Glauch, Dominik Brunner, Julia Marshall, Nikolai Ponomarev, Haoyue Tang, and Stavros Stagakis
Synopsis: This study develops a high-resolution (10 m, hourly) urban biogenic CO₂ flux framework using VPRM and its variants to capture fine-scale variability in vegetation. Applied to Munich, results show urban vegetation offsets 2.0–2.8% of annual anthropogenic emissions, with trees as main sinks and grasslands as net sources. Summer daytime uptake can match or exceed emissions. Model evaluations confirm strong performance, with UrbanVPRM improving urban estimates and VPRM-modified enhancing grassland accuracy, demonstrating the importance of fine-scale modeling for urban carbon assessments.
Demonstration of direct air capture of CO2 using microalgae raceway reactors
Authors: R. Arraga, M. Barceló-Villalobos, R. Esteitie, M. Ahaddouch, C. Sánchez-Salinas, F.G. Acién
Synopsis: This study demonstrates a bio-based DAC system integrated into a 600 m² microalgae raceway reactor using Scenedesmus sp. The system captures CO₂ directly from ambient air, achieving 95% removal efficiency while sustaining biomass productivity (12 g m⁻² day⁻¹). Fine-bubble aeration and passive absorption supply nearly all carbon for growth, with energy demand (~2.9 kWh kg⁻¹ CO₂) comparable to engineered DAC technologies. The approach provides a scalable, low-cost, renewable-compatible pathway for CO₂ removal while producing biomass, supporting decentralized carbon-negative solutions.
Decades of Increased Emissions from Forest-Fueled BECCS - Preprint
Authors: Timothy Searchinger, Liqing Peng, Daniella Russi, Charles Canham
Synopsis: This study evaluates BECCS using wood from existing forests and finds it unlikely to deliver negative emissions within 150 years. Most carbon emissions occur before the power plant, making capture ineffective; wood’s high carbon intensity and lower electricity efficiency lead to higher emissions than natural gas for decades and ~3.5× higher electricity costs. Even partial use of residues or fast-growing plantations offers limited improvement. Findings caution against current forest-sourced BECCS policies and provide a model for policymakers to explore alternative scenarios.
In-situ deep ocean monitoring reveals rapid kelp degradation limits marine biomass-based carbon sequestration potential and alters benthic ecosystems
Authors: Kohen W. Bauer, Paulo V. F. Correa, Alex Lupin, et al.
Synopsis: This study evaluates macroalgae sinking for carbon dioxide removal in the Northeast Pacific oxygen minimum zone. A year-long in-situ experiment showed over 90% of kelp biomass decomposed within ~100 days, mainly via microbial and faunal activity, limiting carbon sequestration. Kelp also altered benthic community structure, affecting 13 species. Findings highlight the importance of site-specific, process-based monitoring to assess ecological impacts and verify carbon storage in biomass-based removal strategies.
Enhancement of carbon sequestration capacity by restoring mangroves in Kaohsiung Jhongdu Wetland Park
Authors: Jung-Yi LAI, Chuan-Wen HO, Chiao-Wen LIN, Wei‐Jen LIN, et al.
Synopsis: This study evaluates carbon sequestration in three restored mangrove species at Jhongdu Wetland Park, Kaohsiung City. Avicennia marina showed the highest carbon capture, followed by Rhizophora stylosa and Lumnitzera racemosa, with restored mangroves outperforming natural mangroves elsewhere in Taiwan. Despite urban park maintenance practices limiting growth, these mangroves act as effective carbon sinks. The study recommends improved management to enhance greenhouse gas reduction and supports mangroves as a nature-based urban climate solution.
Thinking at the megaton scale: Community reflections across three different marine carbon-dioxide removal strategies
Authors: Terre Satterfield, Sara Nawaz, Devin Todd, Kendra Jewell, Pieter Romer
Synopsis: This study explores public perceptions of mCDR at scale in British Columbia, Canada. Using deliberative workshops with First Nations and environmental groups, participants considered three technologies—ocean alkalinity enhancement, direct air capture with sub-seabed storage, and macroalgae cultivation/sinking—designed to remove 2 Mt CO₂/yr. Thinking at scale revealed cognitive challenges, nuanced trade-offs across materials, energy, lifespan, and governance, and concerns about “unnatural” approaches. Findings highlight the importance of engagement designs that incorporate scale, components, and systemic impacts in mCDR research.
Comprehensive structural characterization of charged polymers involved in moisture-driven direct air capture
Authors: Gayathri Yogaganeshan, Rui Zhang, Golnaz Najaf Tomaraei et al.
Synopsis: This study investigates moisture-swing direct air capture (MS-DAC) using alkaline anion-exchange polymers Fumasep FAA-3 and IRA-900. Structural analyses (XRD, SAXS/WAXS, AFM, FIB-SEM, TEM) revealed that CO₂ uptake and kinetics are strongly influenced by macropore architecture and charge density, while water sorption is governed by molecular-scale structure. IRA-900’s macroporosity led to faster, higher CO₂ capture. Findings highlight how material structure dictates moisture-driven DAC performance, guiding design of more energy-efficient polymers.

Biochar’s Washington Playbook - with Maureen Walsh | The CDR Policy Scoop

Biochar's Washington Playbook - with Maureen Walsh

The CDR Policy Scoop

31:14

“In this episode of The CDR Policy Scoop, Sebastian Manhart and Eve Tamme are joined by Maureen Walsh, Executive Director of the US Biochar Coalition (USBC), to discuss how biochar has quietly built one of the most resilient policy positions of any CDR technology in the United States.
Recorded amid tariff pressures, farm bill limbo, and a Washington reshaped by the second Trump administration, the conversation gets straight to the question: is this political moment different? Maureen’s answer is yes, but biochar is finding opportunities others aren’t, by refusing to be defined as a climate technology.
The episode unpacks the strategic reframe at the heart of USBC’s approach: positioning biochar as a solution to waste, wildfires, PFAS contamination, and farmer resilience rather than leading with carbon removal. Maureen explains how this opens doors across the aisle, from senators focused on carbon sequestration to those who just need to deal with mountains of woody biomass before fire season.
The discussion dives into the legislative machinery: the Carbon Resources Innovation Act (Senate Bill 3778), a technology-neutral update to 45Q that would make biochar and other CDR methods eligible for the tax credit without naming them explicitly. Maureen breaks down why 45Q doesn’t currently cover biochar, how BBBA reshaped the tax credit landscape, and why biochar survived the cut when other technologies didn’t. Sebastian and Maureen also explore the art of Hill advocacy, the 20-minute meeting, the constituency-first argument, and why cultivating champions now is the only way to be ready when the next big tax vehicle arrives.
Maureen walks through USBC’s concrete wins: the EPA’s landmark 2024 ruling that pyrolysis of clean cellulosic biomass is no longer classified as waste incineration, and biochar’s dedicated section in Fix Our Forests, which has passed the House with bipartisan support. She also details the USDA conservation practice codes already paying farmers and producers to use biochar, and the patchwork of regional implementation that USBC is steadily working to fix.
The episode closes with two lessons every CDR sector should hear: drop the word sustainability and start talking about resilience, and if you’re still going to Washington alone, you’re already behind.”

The Endless Pursuit of Alkalinity—w/ Omar Sadoon, Planetary Technologies | Reversing Climate Change

390: The Endless Pursuit of Alkalinity—w/ Omar Sadoon, Planetary Technologies

Reversing Climate Change

41:34

“Is all of carbon removal really just about alkalinity? There’s a case to be made for quite a lot of it. Weathering, ocean alkalinity enhancement, even parts of direct air capture—they all come back to manipulating pH and moving basic materials to where they can cancel out excess acid in the atmosphere and ocean.
Omar Sadoon is the Director of Strategic Partnerships at Planetary Technologies, an ocean alkalinity enhancement company working to remove carbon by adding carefully-sourced alkaline materials to the ocean.
Listen in to hear about the enormous logistical and scientific puzzle of finding the right alkalinity sources, getting them to the right ocean sites without breaking the LCA, and the lessons learned from Planetary’s Cornwall and Tufts Cove projects. It’s a show about community engagement, the surprising value of relationships in carbon removal sales, humor, and how Omar’s background as a mental health nurse shaped his approach to partnership building.”

Permanent CO2 removal through enhanced weathering | Silicate Carbon

“Silicate is the first enhanced weathering company to leverage the massive carbon removal potential of limestone.
Weathering reactions between carbonic acid and minerals create bicarbonate, a stable form of inorganic carbon. When transported to the ocean, bicarbonate has a residence time of 80,000 years, constituting a carbon sink on climate relevant timescales. However, quantifying carbon removal by these reactions is complex, and an accurate, precise, internally consistent approach for measurement is integral to scaling enhanced weathering.
Silicate measures carbon dioxide removal across solid, liquid, and gaseous phases by conducting soil sampling, soil water sampling, and soil-air gas flux testing. This video details our work in Wexford, Ireland, since 2021 to measure carbon dioxide removal through limestone enhanced weathering.”

VM0042, v3.0 Public Consultation | Verra

In this webinar, the Verra team provides an overview of the public consultation on a major revision to VM0042 Improved Agricultural Land Management, v2.2 and VMD0053 Model Calibration, Validation, and Uncertainty Guidance for Biogeochemical Modeling for Agricultural Land Management Projects, v2.1 in the Verified Carbon Standard (VCS) Program. The consultation also included a template for model calibration and validation reports, as well as a Soil Sampling and Analysis (SSA) Handbook.
The updated versions of VM0042 and VMD0053 aim to maximize consistency with other VCS methodologies. They would also bring VM0042 into alignment with version 5 of the VCS Program and increase the methodology’s flexibility by making it adaptable to agronomic reality across global geographies.”

Our Coasts, Resiliency, and Carbon Removal: A California Case Study | Ocean Science Trust

“This webinar exploreed how coastal resilience projects can be designed to advance both climate adaptation and marine carbon dioxide removal (mCDR). An overview presentation will capture findings from a new roadmap, “Our Coasts, Resiliency, and Carbon Dioxide Removal”, focused on opportunities to integrate abiotic mCDR into US coastal infrastructure, highlighting four case study states, including California. These case studies illustrate the carbon removal pathways and policy mechanisms that are likely to enable such work. The report further highlights justice principles, research priorities, and recommendations for government, practitioners, and funders that would move these ideas towards implementation. A panel discussion will follow the presentation to further highlight research needed to advance such projects, with a focus on coastal resilience practitioner perspectives.”
