RESEARCH PAPERS
Evaluating the carbon capture potential of industrial waste as a feedstock for enhanced weathering
Xu, P., & Reinhard, C. T. (2025). Evaluating the carbon capture potential of industrial waste as a feedstock for enhanced weathering. IOP Science.
Synopsis: Meeting climate goals will likely require deep emissions cuts and large-scale carbon dioxide removal. Enhanced rock weathering accelerates natural CO2 uptake but faces feedstock sourcing challenges. This study evaluates industrial silicate waste, such as steel slag and cement waste, as alternative ERW feedstocks. Modeling suggests up to ~400 GtCO2 capture potential by 2100. Earth system simulations assess ERW’s climate and ocean impacts, providing insights into its large-scale feasibility.
An integrated solution to mitigate climate change through direct air capture and diabatic compressed air energy storage
Han, Y., Liu, Y., Peng, X., Peng, B.-Y., Ding, Y., Du, W., Zhong, W., & Qian, F. (2025). An integrated solution to mitigate climate change through direct air capture and diabatic compressed air energy storage. Energy Conversion and Management: X
Synopsis: This study integrates liquid-based direct air capture (L-DAC) with diabatic compressed air energy storage (D-CAES) to address energy and environmental challenges. By capturing CO2 emitted during D-CAES discharge, the system enhances sustainability while using its own electricity. Simulations show a 59.27% round-trip efficiency, $0.53/kWh electricity cost, and $259/tCO2 capture cost. These findings provide insights for improving DAC and energy storage integration in sustainable commercial applications.
A new hope or phantom menace? Exploring climate emotions and public support for climate interventions across 30 countries
Baum, C. M., Brutschin, E., Fritz, L., & Sovacool, B. K. (2025). A new hope or phantom menace? Exploring climate emotions and public support for climate interventions across 30 countries. Risk Analysis.
Synopsis: This global study (30,284 participants, 30 countries) explores the link between climate emotions and support for climate interventions like Carbon Dioxide Removal and Solar Radiation Modification. Hope and worry were most positively correlated with support. Advanced economies reported weaker climate emotions. Reading about ecosystem-based CDR evoked the most hope, while SRM the least. Findings highlight emotions' role in shaping climate intervention perceptions and policy support.
Novel Field Experiment on Alkalinity Enhancement in Intertidal Environments—A Trailblazer for Natural Climate Solutions
Mendes, I., Lübbers, J., Schönfeld, J., Baldermann, A., Carrasco, A. R., Cravo, A., ... & Stamm, F. M. (2025). Novel field experiment on alkalinity enhancement in intertidal environments—a trailblazer for natural climate solutions. Journal of Geophysical Research: Biogeosciences, 130(3), e2024JG008591.
Synopsis: Marine alkalinity enhancement (MAE) is a proposed method to increase CO₂ uptake by accelerating the weathering of mafic minerals in seawater. This study introduces an in situ experiment in Portugal’s Ria Formosa lagoon, deploying olivine and basalt substrates in a salt marsh. Six-month data show elevated alkalinity in treated water samples, validating the approach. The study details experimental methods, highlights strengths and limitations, and provides recommendations for scaling MAE as a CO₂ removal strategy.
Meeting Carbon Dioxide Removal Demand in 2030: The Potential of Macroalgae Cultivation and Harvest
Siebert, L., Wu, J., Bednarz, L. K., Keller, D., Meier, F., Merk, C., ... & Rickels, W. Meeting Carbon Dioxide Removal Demand in 2030: The Potential of Macroalgae Cultivation and Harvest. Journal of Ocean and Coastal Economics, 12(1), 1.
Synopsis: Many countries have set net-zero targets, but few incentivize carbon dioxide removal. Based on Paris Agreement targets, estimated global CDR demand in 2030 ranges from 124 to 1064 MtCO₂, primarily from wealthy regions with high abatement costs. Without international emissions trading, demand remains high in places like Canada, Japan, the UK, and the EU. Marine CDR, such as macroalgae cultivation, could contribute, but timely policy support is needed to scale these solutions effectively.
Phase Change-Mediated Capture of Carbon Dioxide from Air with a Molecular Triamine Network Solid
Huang, A. J., Gupta, A. K., Jiang, H. Z. H., Zhuang, H., Wenny, M. B., Klein, R. A., Kwon, H., Meihaus, K. R., Furukawa, H., Brown, C. M., Reimer, J. A., de Jong, W. A., & Long, J. R. (2025). Phase change-mediated capture of carbon dioxide from air with a molecular triamine network solid. ACS Publications.
Synopsis: The search for efficient CO₂ capture materials is crucial for climate mitigation. This study introduces a solid molecular triamine, 1,3,5-tris(aminomethyl)benzene (TriH), which rapidly absorbs CO₂ from humid air, forming a crystalline ammonium carbamate network. TriH achieves record CO₂ absorption of 8.9 mmol/g, with humidity lowering the activation barrier for capture. These findings highlight tunable polyamines as a promising new class of high-capacity CO₂ absorbents for scalable carbon removal.
Efficient and stable direct air capture with amine-functionalized MIL-100(Cr) metal-organic framework
Sun, M., Zhao, M., Zhao, L., Ma, J., & He, H. (2025). Efficient and stable direct air capture with amine-functionalized MIL-100 (Cr) metal-organic framework. Environmental Functional Materials.
Synopsis: Metal–organic frameworks (MOFs) show promise for Direct Air Capture (DAC) due to their tunable structures and high surface areas. This study evaluates MIL-100(Cr) modified with PEI, TEPA, and DEA for CO₂ capture under DAC conditions. PEI-modified MIL-100(Cr) achieved 1.21 mmol/g adsorption capacity and retained over 90% efficiency after 20 cycles. Humidity enhanced amine site utilization, and PEI-modified MOFs exhibited superior oxidative stability, offering key insights for optimizing DAC adsorbents.
Addition of biofertilizers with crop residue in conservation agriculture improves soil carbon sequestration: a long-term field study
Roy, D., Sinha, A. K., Rakesh, S., Rao, K. K., Sahoo, S., Bhattacharya, P. M., ... & Padbhushan, R. (2025). Addition of biofertilizers with crop residue in conservation agriculture improves soil carbon sequestration: a long-term field study. Tropical Ecology, 1-13.
Synopsis: A 12-year study in India’s lower Indo-Gangetic plain examined how tillage, crop residue, and biofertilizers impact carbon sequestration in an acid alluvial soil. Zero tillage (ZT) and residue addition significantly increased soil organic carbon (SOC), with biofertilizers further enhancing sequestration in surface layers. The highest C sequestration and CO₂ mitigation occurred under conventional tillage with residue and biofertilizers. Findings highlight the role of sustainable practices in improving soil health and carbon storage.
Exploring Phosphonium-Based Anion Exchange Polymers for Moisture Swing Direct Air Capture of Carbon Dioxide
Velazco‐Medel, M. A., Niimoto, K. T. M., & Green, M. D. (2025). Exploring Phosphonium‐Based Anion Exchange Polymers for Moisture Swing Direct Air Capture of Carbon Dioxide. Macromolecular Rapid Communications, 2401073.
Synopsis: This study evaluates ammonium and phosphonium-based polymeric ionic liquids (PILs) for moisture-swing direct air capture of CO2. The phosphonium PIL with methyl groups [PVBT-MeP] achieves the highest CO2 capture (≈510 µmol g⁻¹) but undergoes oxidative degradation. The ammonium PIL with butyl groups [PVBT-BuN] shows superior stability over multiple cycles. Findings highlight phosphonium-based PILs' high capacity while emphasizing the need for stability optimization through structural design.
A Framework for Integrating Spatial Uncertainty into Critical Zone Models: Application to Enhanced Weathering
Rogers, B., & Maher, K. (2025). A framework for integrating spatial uncertainty into critical zone models: Application to enhanced weathering. CDRXiv.
Synopsis: Spatial heterogeneity complicates Critical Zone characterization, especially with sparse or repeated sampling. This study presents a probabilistic framework to systematically manage spatial uncertainty in measuring transformations. Using variance propagation, sensitivity analysis, and stochastic simulation, it optimizes sampling for enhanced weathering assessments. Findings highlight the need for accurate baseline variance estimates and suggest limitations for element-mixing models in near-term constraints.
Co-benefit of forestation on ozone air quality and carbon storage in South China
Liu, Z., Zhou, M., Li, D., Song, T., Yue, X., Lu, X., ... & Zhang, L. (2025). Co-benefit of forestation on ozone air quality and carbon storage in South China. Nature Communications, 16(1), 2429.
Synopsis: Forestation-driven greening in South China has enhanced carbon storage and improved air quality, but its full effects remain underexplored. Using satellite data, forestry statistics, and atmospheric modeling, this study finds that forestation reduces surface ozone by enhancing dry deposition and suppressing turbulence. From 2005–2019, greening lowered ozone exposure by up to 41% and increased forest carbon storage by 1.8 Pg C. Future forestation could further enhance storage and ozone mitigation, supporting carbon neutrality.
Investigation of the decarbonization performance of K2CO3/ZrO2 adsorbent for direct air capture
Qi, Z., Chen, X., Xu, Z., Liu, Z., Ma, J., Liang, C., & Liu, D. (2025). Investigation of the decarbonization performance of K2CO3/ZrO2 adsorbent for direct air capture. Chemical Engineering Journal, 161420.
Synopsis: Direct Air Capture using alkali metal-based adsorbents shows promise but faces challenges like high regeneration temperatures and low cycling efficiency. This study synthesizes a K₂CO₃/ZrO₂ composite adsorbent, analyzing its performance using advanced characterization techniques. ZrO₂ lowers regeneration temperature, and humidity significantly affects CO₂ capture. Under optimal conditions, the adsorbent achieves 1.18 mmol/g capacity and retains 92% efficiency after 10 cycles, demonstrating strong DAC potential.
Assessing CO2 fluxes during enhanced weathering from soils through a mesocosm lens
Chiaravalloti, I., Zhang, S., & Planavsky, N. (2025). Assessing CO₂ fluxes during enhanced weathering from soils through a mesocosm lens. CDRXiv.
Synopsis: Gigatonne-scale CO2 removal is essential alongside decarbonization to meet climate goals. Enhanced weathering (EW) offers potential for carbon sequestration but raises questions about its impact on soil organic carbon (SOC) decomposition. A greenhouse mesocosm study found no significant correlation between CO2 fluxes and soil pH or basalt application, suggesting other factors like temperature and moisture dominate. While minor changes in soil carbon were observed, they were not large enough to affect CO2 emissions.
In-situ amine modification of porous polymer/silica spiral wound module for CO2 capture from ambient air
Zheng, R., Jiang, M., & Fan, Y. (2025). In-situ amine modification of porous polymer/silica spiral wound module for CO2 capture from ambient air. Chemical Engineering Journal, 161078.
Synopsis: Traditional powdery solid amine adsorbents face challenges in high-flow Direct Air Capture systems due to high pressure drops. This study develops a flexible membrane solid amine adsorbent using a cellulose acetate/silica composite in a spiral wound module, reducing pressure drop while maintaining high CO₂ adsorption capacity. The adsorbent achieves up to 2.37 mmol/g under humid conditions and demonstrates strong performance even at sub-ambient temperatures, making it a promising DAC solution.
Exploring the impact of hourly variability of air condition on the efficiency of direct air capture
Jung, H., Kim, K., Jeong, J., Jamal, A., Koh, D. Y., & Lee, J. H. (2025). Exploring the impact of hourly variability of air condition on the efficiency of direct air capture. Chemical Engineering Journal, 160840.
Synopsis: This study analyzes the impact of temperature and humidity fluctuations on DAC efficiency using dynamic simulations and Bayesian optimization. High humidity increases energy demand, while hourly air variations degrade performance by up to 35.9%. Re-optimizing parameters improved efficiency by ~5%, highlighting the need for adaptive control systems to enhance DAC scalability and economic viability.

CORSIA vs ETS - what will actually clean up aviation? | The CDR Policy Scoop
"Aviation is responsible for almost 1Gt of CO2 emissions, or 2.5% of global emissions. Up to 4% when accounting for non-CO2 climate warming effects. And demand is only going up: 3-4% year-on-year.
Aviation is also notoriously hard to decarbonise: most hope is placed on sustainable aviation fuels (SAF). Given there will always be considerable residual emissions (ICAO: 200Mt-950Mt in 2050), carbon removal is central to aviation’s net-zero aspiration for 2050.
From a policy perspective, it is incredibly challenging to regulate, as 61% of aviation emissions are emitted on international flights and only 39% within a single country’s boundaries.
A promising solution is emission trading systems for domestic/regional emissions (think EU ETS) and CORSIA for international emissions.
Sounds easy? The reality is incredibly complex, messy, and potentially worrying.
Listen in to hear Eve Tamme and Sebastian Manhart unpack this topic and provide clear solutions for what could be done in future."

Enhancing Forest Carbon Capture with Soil Microbiome and Rock Weathering | Remove and Reflect Podcast
"In this episode, Mr. Sun (AI-character) & Ms. Remove (AI-character) dive deep into a new research paper (preprint) that investigates methods to enhance carbon dioxide removal in reforestation efforts. A large-scale field trial tested the combined impact of modifying the soil microbiome and applying enhanced rock weathering (ERW) using crushed silicate rock. The study monitored thousands of trees over three years, revealing that inoculating saplings with soil from mature forests boosted their early growth, while ERW significantly increased aboveground carbon storage and plant nutrients. The findings suggest that integrating either microbiome enrichment or ERW can substantially increase carbon sequestration in young forests, though their combined application did not show additive benefits, implying practitioners may need to choose one approach. Ultimately, this work highlights promising strategies for maximizing the carbon capture potential of reforestation projects but emphasizes the need for further research across diverse environments.

This is CDR: Mast Reforestation | OpenAir
"Reforestation is one of the most powerful natural climate solutions, but how can it scale to meet the urgent need for carbon removal? In this episode of This is CDR Series, we sit down with Mast Reforestation, a startup which is pioneering a novel carbon removal pathway: biomass burial to generate CDRs that also finances reforestation.
Mast is rethinking reforestation—combining seed collection, nursery innovation, biomass burial (i.e. BiCRS), and carbon finance to accelerate ecosystem recovery and long-term carbon sequestration. Join us as we explore how their approach is reshaping carbon markets and supporting resilient forests in a warming world."
Kelp Currency: Unlocking the True Value of the Ocean’s Forests | Seatrees
"Kelp forests have the power to protect marine life, absorb carbon, and reverse climate change - so why aren’t they getting the funding they deserve?
Kelp Currency explores the Seatrees Kelp Carbon Science Project and the groundbreaking research from the Scripps Institution of Oceanography to quantify the carbon benefits of wild kelp forests and develop a methodology that could unlock financial support for large-scale kelp restoration around the world.
As climate change accelerates the loss of these vital ecosystems, this research is critical in proving that kelp forests are a key solution for a healthier planet. With up to 90% of California’s kelp forests lost in some areas, now is the time to invest in science that could help regenerate them."

Understanding the Basics of Pennsylvania’s Carbon Sequestration Law | Center for Agricultural and Shale Law
"On July 17, 2024, Pennsylvania Governor Josh Shapiro signed into law SB 831, now Act 87 of 2024, known as the “Carbon Capture and Sequestration Act,” allowing for the underground storage of carbon dioxide in the state.
This webinar provides an overview of the law’s major provisions, including the ownership and conveyance of pore space and permitting and operating procedures, and discuss related legal issues, including potential liabilities associated with storing carbon dioxide."
Microalgae Biocomposites for Carbon Removal from Amine Solutions | Podcast | Remove and Reflect Podcast
"In this episode, Mr. Sun (AI-character) and Ms. Remove(AI-character) discuss a new research that investigates an innovative method for carbon dioxide removal from amine solutions, a common industrial capture technique, by using living microalgae immobilized on loofah sponges. The study explores the potential of these biocomposites to regenerate carbon dioxide-rich triethanolamine (TEA) solutions through microalgae photosynthesis, offering a more energy-efficient alternative to traditional solvent regeneration. Experiments compared the CO2 removal rates of the biocomposites to suspended microalgae systems under various TEA concentrations and CO2 loading levels, demonstrating the enhanced efficiency and TEA tolerance of the immobilized algae. This integrated biological and chemical approach aims to improve existing carbon capture capabilities and contribute to sustainable development goals.
