te Pas (2026): Towards “set-in-stone” co-deployment of enhanced rock weathering and biochar – an experimental study on their CO₂ removal and agronomic co-benefits

Emily E. M. te Pas, IN: Wageningen University, https://doi.org/10.18174/681512

To limit global temperature rise well below 2⁰C, Carbon Dioxide (CO₂) Removal (CDR) strategies, such as Enhanced Rock Weathering (ERW) and biochar, are urgently required. Besides CDR, ERW releases nutrients and trace metals, while biochar surfaces may bind these weathering products. The main objective of this research was to experimentally study whether and through which processes ERW, and biochar co-deployment, can promote carbon sequestration, while limiting trace metal risks and providing agronomic co-benefits.

Mehnert et al. (2026): Long-term scenarios and energy system impacts of technological carbon dioxide removal deployment in Finland

Johanna Mehnert, Kati Koponen, Tomi Lindroos, Tiina Koljonen and Heidi Kirppu, IN: Environmental Research: Energy, https://doi.org/10.1088/2753-3751/ae57b0

This study analyzed energy system impacts of technological carbon dioxide removal (CDR) deployment in Finland. The authors modeled long-term scenarios up to 2050 for four CDR technologies: bioenergy with carbon capture and storage (BECCS), biochar soil amendment, direct air carbon capture and storage (DACCS), and enhanced weathering of mining rock waste (EW). An integrated energy economic model compiled using the TIMES-model generator was used to produce cost-minimal development scenarios for Finland’s energy system, including CDR technologies. Three scenarios were modeled: one without a specific CDR target and two with low- and high CDR targets.

Petersen et al. (2026): Assessing CO₂ storage in Danish biochars using inertinite benchmarking

Henrik I. Petersen, Jonathan H. Lindhardt, Natalia Lukasik, Aleksandra Malachowska, Ole-Kenneth Nielsen, Arezoo Taghizadeh-Toosi, Hamed Sanei, IN: Biomass and Bioenergy, https://doi.org/10.1016/j.biombioe.2026.109179

This study evaluates the carbon fractions and CO₂ removal (CDR) potential of a suite of Danish biochar samples produced from typical agricultural feedstocks (wheat straw, wood), digestate, and organic waste across a range of pyrolysis temperatures. The CO₂ storage potential per unit mass of biochar is expressed using the directly measured inertinite carbon concentration (Cinert, wt.%) determined through the inertinite benchmarking methodology.

Wahby et al. (2026): Recent Advances of Biochar-based Engineered Materials for Efficient Removal of CO₂: From Lab to Industrial Scale Applications

Anass Wahby, Nouha El Mail, Youssef Aoulad El Hadj Ali, Abdelmonaim Azzouz, Ibrahim Arhoun, Mounir Manssouri, Mostafa Stitou and Suresh Kumar Kailasa, IN: RSC Advances, https://doi.org/10.1039/D5VA00432B

Growing concerns about greenhouse gas emissions have driven significant efforts toward developing advanced materials for the capture and removal of carbon dioxide (CO₂) from different environments. Among these, biochar-based engineered materials have emerged as promising sorbents for physical adsorption and separation processes, owing to their tunable structure, surface functionality, and potential for scalable production. This review summarizes recent advances in the preparation and application of biochar-based engineered materials for CO₂ capture, highlighting the influence of synthesis methods on their structural properties and adsorption performance. A comparative analysis of different biochar-derived materials is presented, focusing on adsorption capacity, selectivity, and reusability.

Kır (2026): Biochar engineering and life-cycle performance of biochar–BECCS systems for carbon dioxide removal

Ali Bertan Kır, IN: Middle East Technical University, https://open.metu.edu.tr/handle/11511/118491

Climate change is driven by the accumulation of greenhouse gases, so alongside rapid CO₂ emission reductions, carbon dioxide removal (CDR) is increasingly needed, and biomass offers a strategic pathway by converting photosynthetically fixed carbon into useful products and energy while enabling net CO₂ removal. Building on this biomass utilization perspective, this thesis bridges sustainable materials science and system-level CDR assessment by first producing and engineering advanced biomass-derived carbon materials (biochar) through one-step impregnation and pyrolysis, and then evaluating biochar as a standardized carbon product within a high-level, integrated biochar (BC) – BECCS (bioenergy with carbon capture and storage) framework (BC+CCS), leveraging the fact that both technologies rely on the same biomass feedstock supply chains.

Ringsby et al. (2026): Closing the carbon removal attribution gap requires an objective atmospheric basis

Alexandra Ringsby, Marc Roston, Gian Mallarino, Mislav Radic, Kate Maher, IN: CDRXiv, https://doi.org/10.5281/zenodo.18510380

Efforts to integrate carbon dioxide removal (CDR) into climate policy, markets, and inventories are advancing rapidly, but without a unified accounting logic to attribute atmospheric impacts. Existing crediting approaches omit upstream emissions, creating a structural “attribution gap” in which removals are credited even as associated emissions remain in the atmosphere. Although it remains small today, the authors find that this gap could reach gigaton-scale annually in biomass-based CDR systems. To address this discrepancy, the authors propose an Objective Atmospheric Basis (OAB): a technology-agnostic accounting framework that tracks carbon transfers explicitly using mass-balance ledger that casts emissions as persistent liabilities and removals as assets.

Dong et al. (2026): Biochar for simultaneous soil remediation and carbon sequestration: application, mechanism, and development prospect – a comprehensive review

Yingbo Dong, Xujiao Guan and Hai Lin, IN: Environmental Earth Sciences, https://doi.org/10.1007/s12665-026-12834-3

Biochar, as a carbon-enriched porous material obtained via pyrolysis of biomass in anoxic environments, exhibits significant potential for application in soil remediation and carbon cycle management due to its unique physicochemical properties. This article reviews the application and action mechanism of biochar in the remediation of heavy metals and organic pollutants contaminated soils, and the effects of carbon sequestration.

Han et al. (2026): Carbon dioxide removal potential of biochar with biomass supply from bioenergy crops in China

Mengjie Han, Chenyi Yuan, Philippe Ciais, Daniel S. Goll, Yi Leng, Minxuan Sun, Nan Meng, Jiaxin Zhou, Xiaomeng Du, Dabo Guan, Wenjia Cai, Rui Wang, Jianxiang Shen, Liang Jing, Qing Zhao and Wei Li, IN: Carbon Neutrality, https://doi.org/10.1007/s42773-025-00564-x

Biochar and bioenergy crop cultivation with carbon capture and storage (BECCS) are two major negative emission technologies for carbon dioxide removal (CDR). However, biochar production is limited by biomass supply, while BECCS depends on costly CCS infrastructure and faces storage constraints. Here, a novel combination of biochar with biomass supply from dedicated bioenergy crops (BCBE) is proposed to overcome their respective limitations. Through retrofitting current biomass power plants in China with pyrolysis systems or CCS, biomass power plants are assumed to use either residues from agriculture and forestry or from dedicated bioenergy crops on abandoned croplands to meet their capacity for biochar production.
