Bolongaro et al. (2026): Life cycle assessment of solid calcium-looping direct air capture and its synergistic dual use for net-negative cement

Vittoria Bolongaro, David Yang Shu, Noah McQueen and André Bardow, IN: Chem Circularity, https://doi.org/10.1016/j.checc.2026.100037

Calcium-looping direct air carbon capture and storage (DACCS) is a mature technology with potential for gigatonne-scale carbon dioxide removal (CDR), yet its environmental impacts remain insufficiently quantified. Here, the authors present the first prospective life cycle assessment of large-scale calcium-looping DACCS based on primary industrial data.

Nishiura et al. (2026): Development of a computable general equilibrium model representing direct air capture and carbon dioxide utilization

Osamu Nishiura, Shinichiro Fujimori and Ken Oshiro, IN: Energy and Climate Change, https://doi.org/10.1016/j.egycc.2026.100250

The establishment of stringent climate goals resulted in the development of various technologies contributing to climate change mitigation. While most of them were developed, at least partially, for other purposes, carbon dioxide removal (CDR) and carbon dioxide capture, utilization and storage (CCUS) are the only technologies developed solely for the purpose of mitigation. Direct air capture (DAC) contributes to climate-change mitigation through CDR and the supply of low-emission fuels. Integrated assessment models (IAMs) have incorporated the latest mitigation technologies, supporting technology development and deployment as well as climate policy formulation. Most scenario studies targeting DAC have applied IAMs with partial equilibrium models at their core. This study developed a computable general equilibrium (CGE) model capable of analyzing mitigation scenarios considering DAC-related technologies.

Bernecker & Müsgens (2026): Direct Air Capture in Europe – Where to Integrate, Where to Store, and What Drives Cost?

Maximilian Bernecker and Felix Müsgens, IN: arXiv, https://doi.org/10.48550/arXiv.2604.05990

Direct Air Carbon Capture and Storage (DACCS) can mitigate hard-to-abate emissions, e.g. from transport or industry. However, there is a wide variety of cost estimates for DACCS, driven, to a significant extent, by differences in electricity cost. At the same time, there is a notable gap in research that integrates direct air capturing systems into long-term energy system models. They separate direct air capturing, carbon transport, and carbon storage and integrate them into a European capacity expansion model for a fully decarbonised electricity system in 2050. They explore how two dimensions affect the total system costs of DACCS. The first dimension is the availability of CO₂ storage locations: In one analysis, storage locations are restricted to offshore storage locations in the North Sea only, i.e. depleted natural gas fields. The alternative analysis comprises suitable storage locations distributed across Europe, including onshore.

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.

Valencia Cotera et al. (2026): Clearing the air: Public sentiment on DACCS in Germany

Rodrigo Valencia Cotera, Paul Bowyer, Lars Buntemeyer, IN: International Journal of Greenhouse Gas Control, https://doi.org/10.1016/j.ijggc.2026.104639

This study conducted a survey to assess the acceptance of DACCS. The survey was conducted in Germany; a country that has historically expressed strong opposition to CO₂ storage. The findings revealed that DACCS is relatively unfamiliar to the public. Benefit perception emerged as the most significant positive determinant of DACCS acceptance, while perceptions of tampering with nature were the strongest negative driver.

Chiani et al. (2026): The Uncertain Policy Price of Scaling Direct Air Capture

Leonardo Chiani, Pietro Andreoni, Laurent Drouet, Tobias Schmidt, Katrin Sievert, Bjerne Steffen, and Massimo Tavoni,IN: arXiv, https://doi.org/10.48550/arXiv.2603.19143

Direct air carbon capture and storage (DACCS) is a promising CO₂ removal technology, but its deployment at scale remains speculative. Yet, its technological, economic, and policy-related uncertainties have often been overlooked in mitigation pathways. This paper conducts the first uncertainty quantification and global sensitivity analysis of DACCS on technological, market, financial and public support drivers, using a detailed-process Integrated Assessment Model and newly developed sensitivity algorithms.

Bolongaro et al. (2025): Prospective life cycle assessment of megatonne-scale direct air carbon capture and storage via calcium-looping

Vittoria Bolongaro, David Yang Shu, Noah McQueen, André Bardow, IN: ChemRxiv, https://doi.org/10.26434/chemrxiv-690cdd17a482cba1228796d2

Calcium-looping direct air capture is a mature technology that could contribute to the gigatonne-scale carbon removal industry. However, the environmental impacts and tradeoffs of its large-scale deployment have not been assessed. Here, the authors perform a prospective life cycle assessment of megatonne-scale calcium-looping DACCS systems, demonstrating removal efficiencies exceeding 80% for autonomous systems by 2030, and ranging from 85% to 96% by 2050, depending on the energy system.

Van der Spek et al. (2025): An Ecosystem of Carbon Dioxide Removal Reviews – Part 1: Direct Air CO₂ Capture and Storage

Mijndert Van der Spek, André Bardow, Chad M. Baum, Vittoria Bolongaro, Vincent Dufour-Décieux, Carla Esch, Livia Fritz, Susana García, Christiane Hamann, Dianne Hondeborg, Ali Kiani, Sarah Lueck, Shrey Kalpeshkumar Patel, Shing Bo Peh, Maxwell Pisciotta, Peter Psarras, Tim Repke, Paola Alejandra Sáenz-Cavazos, Ingrid Schulte, David Yang Shu, Qingdian Shu, Benjamin Kenneth Sovacool, Jessica Strefler, Sara Vallejo Castaño, Jin-Yu Wang, Matthias Wessling, Jennifer Wilcox, John Young and Jan Christoph Minx, IN: Energy & Environmental Science, https://doi.org/10.1039/D5EE01732G

Direct air CO₂ capture and storage (DACCS) is a technology in an emerging portfolio for carbon dioxide removal (CDR), understood to play a critical role in stabilising our climate by offsetting residual carbon emissions from hard-to-abate sectors and ensuring net-negative greenhouse gas emissions post reaching net-zero. Carbon dioxide removal is anticipated to gain further importance due to lacking progress on climate reduction efforts. Meanwhile, CDR, including DACCS, is transitioning from a merely scientific effort to implementation, requiring policy and decision making based on a comprehensive understanding of the scientific body of knowledge. This calls for a source of information synthesising the body of knowledge on CDR, which the authors set out to author and publish as a series of systematic review papers on CDR. This first review focuses on DACCS. Given the need for practical implementation, this review reports not only on DACCS technology and state of development, but also on the state-of-the-art in technoeconomic and environmental performance, policy, equity & justice, public perceptions, and monitoring, reporting, and verification, closing with the foreseen role for DACCS in future decarbonisation scenarios.

Wang et al. (2025): Life-cycle levelized cost and carbon removal efficiency of solid sorbent direct air carbon capture and storage in China

Yuxuan Wang, Xian Zhang, Jing-Li Fan, IN: International Journal of Greenhouse Gas Control, https://doi.org/10.1016/j.ijggc.2025.104440

The authors developed a comprehensive full-chain solid sorbent direct air carbon capture and storage (DACCS) system assessment model that integrates all key stages, including DAC plant construction, CO₂ capture, compression, transport, and storage. This model was applied to 28 provinces across China to evaluate the life-cycle levelized cost of CO₂ removal (LCOD) and carbon removal efficiency (CRE) of DACCS systems powered by 36 different energy supply configurations.
