Yuan et al. (2026): Monolithic adsorbent with low pressure drop and high cycling stability enabled by an anchor effect for direct air CO₂ capture

Peng Yuan, FeiFan Huang, PeiJun Li, HuiXian Tian, YuChen Zhou, Tao Li, IN: Journal of Environmental Chemical Engineering, https://doi.org/10.1016/j.jece.2026.121233

The continuous rise in atmospheric CO₂ is a major driver of global warming, creating the urgent need for negative emission technologies. Direct air capture (DAC) based on solid amine adsorbents has attracted increasing attention due to their balanced performance in capacity, cost, and scalable fabrication. However, DAC operation typically requires high gas flow rates, making low pressure drop and strong support-active phase binding critical to limiting fan energy consumption and ensuring long-term durability. To address this challenge, a four-channel micro-monolithic adsorbent was developed using an alumina ceramic support, polyethyleneimine (PEI) as the active phase, and 3-aminopropyltriethoxysilane (APS) as a coupling agent.

Lunstrum et al. (2026): A Parameterized Lifecycle Assessment of Ex Situ CO₂ Mineralization, Using Olivine as a Case Study

Abby Lunstrum, Alex Wyckoff, Alec Wallace, Rylie Pelton, Anastasia O’Rourke, IN: Environmental Science & Technology, https://doi.org/10.1021/acs.est.5c02627

To achieve global climate goals, novel technologies are needed to efficiently capture and durably store atmospheric CO₂. Reacting CO₂ with silicate minerals in engineered systems, often called ex situ mineralization, is one such approach. The potential net climate benefit of ex situ CO₂ mineralization is unclear, however, as it depends on the technology pathway, location, energy and resource demands, and potential for avoided emissions via co-product utilization. Accurately quantifying these factors in site-specific scenarios is critical for assessing a project’s carbon footprint. Here, the authors present a parameterized lifecycle assessment (LCA) model to quantify the net CO₂e emissions of a range of ex situ mineralization scenarios, considering both direct and avoided emissions.

Tang et al. (2026): Tropical forest carbon sequestration accelerated by nitrogen

Wenguang Tang, Jefferson S. Hall, Oliver L. Phillips, Roel J. W. Brienen, S. Joseph Wright, Michelle Y. Wong, Lars O. Hedin, Michiel van Breugel, Joseph B. Yavitt, Phillip M. Hannam & Sarah A. Batterman, IN: Nature Communications, https://doi.org/10.1038/s41467-025-66825-2

Understanding forest carbon sequestration is crucial for predicting and managing the carbon cycle, yet we lack evidence for whether, when and how the carbon sink in tropical forests recovering from land use change is nutrient limited. Here the authors show how the tropical forest recovery rate responds to experimental nutrient manipulation over a secondary succession gradient in a naturally recovering Central American landscape.

Burns & Webb (2026): The Biodiversity Beyond National Jurisdiction Agreement and its Role in Governance of Marine Carbon Dioxide Removal

William C. G. Burns, Romany Webb, IN: SSRN, https://doi.org/10.2139/ssrn.6023674

This article suggests that the Biodiversity Beyond Jurisdiction Agreement, which will enter into force in January of 2026, and which actively discussed marine carbon dioxide removal during its negotiation, might serve a critical role in coordinating the responses of various regimes and institutions to marine carbon dioxide removal and establishing important guardrails for research and potential deployment.

Allen et al. (2026): Projected impact of combined high-end atmospheric carbon dioxide levels and tree restoration on albedo, forest emissions and carbon uptake

Robert J. Allen, Taylor Adkins & Olivia E. Clifton, IN: Communications Sustainability, https://doi.org/10.1038/s44458-025-00003-9

Tree restoration is seen as a nature-based solution to climate change, because trees remove carbon from the atmosphere. However, tree cover can influence surface temperatures in other ways, for example by changing albedo and enhancing evapotranspiration. These impacts may, in turn, be affected by increasing atmospheric carbon dioxide concentrations. Here, the authors present simulations with a coupled atmosphere-land-slab-ocean model to investigate how doubled atmospheric carbon dioxide levels affect warming in a high-end scenario where afforestation covers a land area 35% larger than the USA.

Flipkens et al. (2026): The carbon dioxide removal potential of cement and lime kiln dust via ocean alkalinity enhancement

Gunter Flipkens, Greet Lembregts, and Filip J.R. Meysman, IN: Biogeosciences, https://doi.org/10.5194/bg-23-399-2026

Ocean alkalinity enhancement (OAE) is a proposed method for atmospheric carbon dioxide removal (CDR), and involves the addition of alkaline minerals to surface waters to elevate seawater alkalinity and enhance atmospheric CO₂ storage. Cement kiln dust (CKD) and lime kiln dust (LKD) are alkaline side streams from the cement and lime industry that have OAE potential due to their widespread availability and fine particle size. Here, the authors evaluated the dissolution kinetics, CO₂ sequestration potential, and ecological risks of CKD and LKD by means of laboratory dissolution experiments.

Han et al. (2026): Solar-driven direct air capture to produce sustainable aviation fuel

Yide Han, Olajide Otitoju, Ariane D. N. Kamkeng, Meihong Wang, Hui Yan, Fisher Millard, Wenli Du & Feng Qian, IN: Nature Communications, https://doi.org/10.1038/s41467-025-67977-x

Renewable energy-powered direct air capture with subsequent utilisation offers a sustainable decarbonisation strategy for a circular economy. Whereas current liquid-based capture technology relies on natural gas combustion for high-temperature calcination, restricting the transition to fully renewable operation. In this study, the authors show a 1 Mt CO₂/year solar-driven process that adopts a hydrogen fluidised solar calciner with onsite catalytic conversion of CO₂ into sustainable aviation fuel.

Herbermann et al. (2026): Assessing BECCUS impacts on the SDGs through a value chain assessment for climate mitigation and energy transition

Joris Herbermann, Bob van der Zwaan & Drielli Peyerl, IN: Discover Sustainability, https://doi.org/10.1007/s43937-025-00121-4

As the urgency for climate mitigation intensifies, Bioenergy with Carbon Capture, Utilization, and Storage (BECCUS) is emerging as a prominent negative emissions technology with significant potential to contribute to carbon removal efforts and sustainable energy systems. This work analyses whether the BECCUS value chain can support progress toward the 2030 Agenda by assessing the impacts across the 17 Sustainable Development Goals (SDGs) and their 169 targets.

Reinhard & Planavsky (2026): The importance of radical transparency for responsible carbon dioxide removal

Christopher T. Reinhard & Noah J. Planavsky, IN: Nature Climate Action, https://doi.org/10.1038/s44168-025-00324-4

Carbon removal is a strongly debated component of societal efforts to address anthropogenic climate disruption, in part because efforts to scale carbon removal could delay or substitute for efforts aimed at mitigating anthropogenic greenhouse gas emissions. Although there is no single solution to this problem, the authors argue here for radical transparency on the data behind carbon removal claims and the data required for evaluating the dollar-per-ton costs of various carbon removal pathways.
