RESEARCH PAPERS
Cost-effective carbon-dioxide removal through water electrolysis and Oxy-BECCS integration
Authors: Samira Rostom, Robert Symonds, Robin W. Hughes, Scott Champagne
Synopsis: This study explores integrating water electrolysis with biomass oxy-combustion and gasification for hydrogen production and CO₂ removal in BECCS systems. All cases achieve net-negative emissions, with pressurized gasification delivering the lowest hydrogen cost ($3.91/kg) and nearly double H₂ output. Combustion offers simpler, lower-cost designs but less efficiency. CO₂ credits ($117/t) can make LCOH cheaper than standalone electrolysis, with electrolyzer-supplied O₂ consistently outperforming ASU-based O₂.
Land Use Pinch Analysis of Carbon Dioxide Removal Portfolios
Authors: Xin Hui Cheng, Yick Eu Chew, Jaya Prasanth Rajakal, Viknesh Andiappan, Bing Shen How, Raymond R. Tan
Synopsis: This study applies land use pinch analysis (LUPA) to evaluate negative emissions technologies (NETs) under land constraints. NETs like afforestation, soil carbon, biochar, DACCS, and BECCS can offset hard-to-abate emissions, but deployment depends on resource trade-offs. Five scenarios show DACCS offers the lowest land footprint (0–0.077 ha/tCO₂eq), outperforming biochar except in shared land use cases. LUPA proves useful for designing balanced, land-efficient CDR portfolios.
The fate of CO2, Ca, and Mg after terrestrial rock weathering
Authors: Maija J. Raudsepp; Sasha Wilson; Benjamin M. Tutolo
Synopsis: This study analyzes 854 water samples from British Columbia’s Central Plateau to define geochemical thresholds for Ca- and Mg-carbonate formation in the silicate–carbonate cycle. Results show maximum alkalinity thresholds of ~5 mEq/kg for Ca-carbonates and ~40 mEq/kg for Mg-carbonates across diverse water types. These insights help optimize geochemical CDR methods like enhanced rock weathering, where bicarbonate offers up to twice the CO₂ removal efficiency of carbonate minerals.
Sustainability analysis of electrochemical direct air capture technologies
Authors: Grazia Leonzio and Nilay Shahb
Synopsis: This study evaluates fully electrified DAC technologies using a hybrid learning curve to assess costs and environmental impacts across locations, seasons, and renewable energy sources. Among electrolysis, electrodialysis, electro-swing adsorption, and proton-coupled electron transfer (PCET), results show electro-swing and PCET offer lower costs and impacts, while electrolysis and electrodialysis are less efficient. A sustainability ranking finds PCET in China (2040–2050) powered by offshore wind as the most viable DAC pathway.
Humans have depleted global terrestrial carbon stocks by a quarter
Authors: Raphael Ganzenmüller, Wolfgang A. Obermeier, Selma Bultan, Seth A. Spawn-Lee, Florian Zabel, Julia Pongratz
Synopsis: This study estimates the global terrestrial carbon deficit—the gap between actual and potential vegetation and soil carbon stocks—using semi-empirical data and machine learning. Results show a 344 PgC (24%) depletion, mainly from pasture (30%), cropland (24%), and forest management (23%). Dynamic global vegetation models underestimate this deficit by 37% on average, exposing key limitations. Findings improve understanding of anthropogenic ecosystem impacts and help refine climate models for nature-based solutions and mitigation policies.
Large-Scale Climate Interventions: Carbon Dioxide Removal and Solar Radiation Management - Book Chapter
Authors: Walker Raymond Lee, Douglas MacMartin & Amanda Borth
Synopsis: This chapter asks whether anthropogenic climate change is “fixable” through climate intervention, focusing on CDR and solar radiation management (SRM). CDR directly offsets emissions but remains costly and immature at scale, while SRM could rapidly cool Earth by altering its energy balance but risks major unintended consequences for ecosystems and societies. Current trends point to 2–4 °C warming by 2100, far above Paris targets. Both approaches face technical, political, and ethical hurdles, requiring much more research and inclusive consultation before large-scale implementation.
Glacial meltwater increases coastal carbon dioxide uptake and sensitivity to biogeochemical change
Authors: Henry C. Henson, Isolde Callisto Puts, Mikael K. Sejr, Lise Lotte Sørensen & Johnna M. Holding
Synopsis: This study examines how Greenland Ice Sheet meltwater alters coastal carbon dynamics. Mixing experiments show freshwater dilution causes a nonlinear reduction in seawater pCO₂, confirmed by carbonate system modeling and long-term fjord data. Freshwater lowers buffering capacity, amplifying sensitivity to biogeochemical processes and acidification. Results reveal meltwater enhances biological control of pCO₂, reshaping Arctic coastal carbon cycling under accelerating ice loss.
Direct air capture of CO2 in an electrochemical hybrid flow cell with a spatially isolated phenazine electrode
Authors: Xinyu Jin, Shijian Jin, Lu Li, Roy G. Gordon, Pan Wang, Michael J. Aziz & Yunlong Ji
Synopsis: This study presents a hybrid phenazine flow cell for pH-swing DAC that overcomes oxygen sensitivity in redox-active organics. Using solid poly(phenazine sulfide) electrodes, the system separates reduced species from air, achieving stable CO₂ capture with high O₂ compatibility. It delivers 99% coulombic efficiency, with energy costs of 73 kJ/mol CO₂ (flue gas) and 104 kJ/mol CO₂ (DAC). This isolation strategy offers a promising route for efficient, oxygen-tolerant DAC and other electrochemical applications.
Evaluating Carbon Dynamics for Enhanced Weathering: An Analysis of Soil CO₂ Efflux an Leachate Alkalinity Data
Authors: Dirk Paessler, Jens Hammes, Anna Anke Stöckel, Ralf Steffens, Ingrid Smet
Synopsis: A 24-month greenhouse study with 67 rock–soil combinations assessed enhanced weathering impacts on carbon cycling using ~1M CO₂ efflux and 6,500 leachate measurements. Results showed three phases: strong disturbance effects early, variable first-year responses, and reduced treatment impacts in year two. Rock dusts often increased CO₂ efflux initially but effects faded. Alkalinity rises indicated some CDR, though inconsistent. High soil CO₂ fluxes vs leachate highlight the need for full carbon balance assessments.
Development of Amine-Functionalized Cerium Dioxide for Direct Air Capture of CO2: A Chemical Adsorption Study
Authors: Xuelong Zhuang, Jae Yeon Hwang, Mi Yeong Ko, Sung Woo Han, Edoardo Magnone, Jung Hoon Park
Synopsis: This study develops APTES-functionalized cerium oxide (CeO₂) adsorbents for direct air capture. Structural analyses confirmed that amine groups and oxygen vacancies were introduced, boosting CO₂ adsorption via synergistic interactions. CO₂-TPD tests showed higher capacity and strong cyclic stability under pure and 400 ppm CO₂, outperforming conventional amine adsorbents. Results highlight APTES–CeO₂ as a promising, efficient, and durable material for scalable DAC applications.
Assessing the Feasibility of Economy-Scale Direct Air Capture Deployment by 2050
Authors: Tatjana Zurbriggen, Nicoletta Brazzola, Adrian Odenweller, Falko Ueckerdt, Joeri Rogelj
Synopsis: This study applies a probabilistic approach to assess DAC growth to 2050. Without strong intervention, DAC is likely to scale only to the megaton level, limiting its climate impact. However, with targeted policy support, particularly to accelerate near-term deployment, DAC could still reach gigaton-scale by mid-century, making it climate-relevant. Results highlight the critical role of policy in determining DAC’s contribution to net-zero goals.
Up-to-date literature review on zero-carbon buildings and cities: energy innovations, challenges, and prospects
Authors: Adnan I. Khdair, Ghaida A. Aburumman, Shayan Gholipour, Masoud Afrand
Synopsis: This review explores advancements, challenges, and prospects for zero-carbon buildings and cities as a climate strategy. It highlights renewable energy, energy efficiency, and new materials, with emphasis on renovating existing buildings for greater carbon reduction. Key issues include standardizing methodologies, improving emission estimates, and applying real-time life cycle optimization. Intelligent technologies and infrastructures are also reviewed, outlining current progress, future directions, and emerging trends.
Constructing Amine-Functionalized Hierarchically Porous Porphyrin-Based Metal–Organic Frameworks for Highly Enhanced Direct Air Capture of CO2
Authors: Xinyu Chen, Jinhai Leng, Fengying Ma, Jianqing Wu, Yi Jin, Fanglin He, Chao Yang, Haomin Huang, Xuquan Liu, Chongxiong Duan, Shanshan Shang, Daiqi Ye
Synopsis: This study develops hierarchically porous porphyrin-based MOFs (HP-PMOFs) with high-density defects and multi-scale porosity to overcome amine loading limitations in CO₂ capture. Functionalization with DETA, TEPA, and PEI significantly boosted DAC performance, with HP-PMOF–DETA achieving the highest uptake (1.40 mmol g⁻¹) and 84% regeneration efficiency after ten cycles at 400 ppm CO₂. Mechanistic analyses showed synergistic physisorption–chemisorption under dry conditions and water-facilitated bicarbonate formation under humidity. These findings highlight amine-functionalized HP-PMOFs as promising DAC adsorbents.
CO2 removal to reach net zero warming of global methane and nitrous oxide emissions of livestock: Comparison of two metrics under different 2050 FAO scenarios
Authors: Fabio Correddu, Mondina Francesca Lunesu, Sara Sechi, Maria Francesca Caratzu, Giuseppe Pulina
Synopsis: This study examines how emission metrics—GWP100 vs. GWP*, shape estimates of livestock methane’s warming impact and associated CDR needs. Using FAO projections to 2050, results show GWP100 can misrepresent methane’s cumulative effect, while GWP* better captures its dynamic temperature impact. Since metrics influence perceived mitigation effectiveness and CDR requirements, especially for methane-heavy sectors, careful metric selection is crucial for designing climate policies aligned with temperature goals.
Chemical activation of ultramafic tailings for improved large-scale CO2 sequestration in mine backfill
Authors: Qianqian Wang, Jianhui Lv, Lijie Guo, Xiaodong Shen
Synopsis: This study demonstrates enhanced CO₂ sequestration in ultramafic copper–nickel tailings using bisulfate activation and a two-stage carbonation process: slurry carbonation followed by secondary carbonation in backfilling materials (BFM). Forsterite and chrysotile showed the highest reactivity, achieving 13.46% CO₂ uptake after three days. Despite minor strength reduction, BFM met engineering standards while serving as a CO₂ sink. Stable carbonates were confirmed via XRD/SEM, and a new DTG-based method quantified efficiency. The approach couples mine backfilling with large-scale carbon mineralization, advancing sustainable mining and CDR.
Biochar-enhanced cement composites as carbon sink under accelerated carbonation curing: Carbon sequestration potential stimulated by biochar porosity
Authors: Yuyang Chen, Binggen Zhan, Binglin Guo, Deyin Tian, Hongcen Li, Ping Ye, Huyong Qin, Peng Gao, Qijun Yu
Synopsis: This study investigates how biochar porosity influences CO₂ sequestration in cement composites under accelerated carbonation curing. Large-porosity biochar enhanced CO₂ transport, boosting inner-layer sequestration by 30.7% and reducing interlayer differences by 65.1%. However, excessive porosity lowered 28-day strength by 20.1%, while fine porosity hindered transport. Results show biochar regulates carbonation via pore structure, balancing carbon storage and strength in cement composites.
Nordic net-zero: counterbalancing residual emissions in the context of unevenly distributed BECCS potentials
Authors: Malin Dufour &Kenneth Möllersten
Synopsis: This study analyzes the role of BECCS trade in achieving net-zero in the Nordics. Sweden has a surplus BECCS potential of ≥19 MtCO₂/yr, which could be transferred to countries with deficits, like Denmark and Iceland, under Article 6 of the Paris Agreement. Norway’s small potential likely meets its goals, while Finland will need domestic BECCS due to forest sink uncertainty. The authors recommend clear targets for reductions vs. removals, assessing national CDR balances, and fostering cross-border collaborations.
Combining organic amendments with enhanced rock weathering shifts soil carbon storage in croplands
Authors: Jaeeun Sohng, Noah W. Sokol, Seth Whiteaker, Radomir Schmidt, Iris Holzer, et al.
Synopsis: A 3-year field study in irrigated maize fields tested enhanced rock weathering (ERW) alone and with compost/biochar. Rock-alone raised pH, inorganic carbon, and boosted particulate and mineral-associated organic matter (POM, MAOM). However, combining rock with organic amendments lowered soil organic C and N compared to organics alone, though IC rose in rock+compost. Results show ERW can promote weathering and C storage but may slow organic C/N accrual, highlighting trade-offs for soil health and climate mitigation.
Earth system responses under a global 2°C-target scenario aligned with China’s carbon neutrality pledge
Authors: Yixiong Lu, Lei Jin, Junting Zhong, Xiaoye Zhang, Yanwu Zhang, Fanghua Wu, et al.
Synopsis: A new SSP2-com scenario combining China’s 2060 net-zero pledge with late-century CDR deployment shows end-of-century warming limited to 1.87°C—below the Paris 2°C goal and cooler than SSP2-4.5 and SSP3-7.0 by 0.51°C and 1.47°C. Despite weaker carbon sinks, accelerated decarbonization in China avoids 0.08–0.29°C of warming. Results highlight that ambitious regional action plus global CDR can stabilize climate, though risks from uneven cooling and ecosystem feedbacks remain.
