However, the computational and data requirements of these models limit their scalability across multiple scenarios and timescales, particularly when trying to capture the range of outcomes under different scenarios. Machine learning (ML) offers a way to streamline these complex processes, enabling efficient modeling with substantially less computational resources. In this study, we combined ML model with an agroecosystem model Daily Century (DAYCENT) to project baseline (2009–2018) and future (2021–2100) biomass yields and SOC changes for three bioenergy crops:Miscanthus, sorghum, and switchgrassacross U.S. agricultural lands. These projections were made under the Shared Socio-economic Pathway 8.5 (SSP5 8.5), using data from the coupled model intercomparison project phase six models. The ML-based reduced order model, trained on field observations and DAYCENT outputs, accurately predicted baseline biomass yields with <em>R²</em> values ranging from 0.96 to 0.98, and SOC changes with <em>R²</em> values between 0.93 and 0.98 across the three bioenergy crops. Under a SSP5 8.5 scenario, Miscanthus and sorghum exhibited lower sensitivity to precipitation and temperature impacts in terms of biomass yield and SOC changes compared to switchgrass. Sorghum and Miscanthus are projected to see an increase in economically viable land area across the continental U.S., with gains of 29 % and 10 %, respectively. The most significant increases for sorghum are expected at higher latitudes. In contrast, economically viable land area is projected to decline by 11 % by 2100 compared to baseline scenarios for switchgrass. Our findings demonstrate the potential of ML-based reduced order models to provide accurate predictions offering opportunity to develop user-friendly agroecosystem analysis tools in future.</div></div>","PeriodicalId":9387,"journal":{"name":"Carbon Capture Science & Technology","volume":"15 ","pages":"Article 100440"},"PeriodicalIF":0.0,"publicationDate":"2025-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144131018","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

High costs driven by economies of scale, CO₂ partial pressures, and large energy demands, along with need for substantial new CO₂ transportation and storage infrastructure, are key barriers to large-scale the deployment of CCUS. This paper introduces the overall National CCUS Assessment Framework (NCAF) platform and its key elements to provide context on how it can be utilized to facilitate strategic planning of CCUS infrastructure at the regional to national scale. The NCAF platform, comprised of 5 components, combines rigorous datasets, costing and life cycle assessment (LCA) methods, optimization models, and visualization methods across the whole CCUS value chain. This paper focuses on the CO₂ Capture Modeling and Costing/LCA Tool providing details on overall approach, development steps, and the application of the techno-economic-environmental machine learning (ML) models to industry archetypes. Preliminary sensitivity and industry analysis show the robustness of the ML models, providing quick and accurate costs and environment burdens. Key parameters including flue gas flow rate and composition, capture rate, and product CO₂ pressure are explored, highlighting the ideal operating conditions when considering solvent-based post-combustion CO₂ capture. An exploratory analysis of over 300 Canadian emitting facilities provides practical information about how costs and overall global warming potential (GWP) vary between industry type, facility location, and production scale.

Circulating Fluidized Bed (CFB) boilers offer fuel flexibility, enabling the integration of more environmentally friendly biogenic or waste-derived fuels such as Solid Recovered Fuel (SRF). However, replacing conventional fuels with high-volatile alternatives poses challenges related to combustion stability and efficiency. Oxygen Carrier Aided Combustion (OCAC) with ilmenite as a bed material enhances combustion efficiency and reduces emissions by facilitating oxygen transport within the fluidized bed. Additionally, oxyfuel combustion offers a promising pathway for carbon capture but is hindered by high oxygen demand. This study combines OCAC and oxyfuel combustion, presenting the first autothermal Oxyfuel-OCAC (Oxy-OCAC) experiments conducted at the 1 MW_th scale, utilizing 100 % SRF as feedstock. The pilot plant enables oxyfuel operation with wet flue gas recirculation and pure oxygen supply, allowing a controlled transition from air-fired to oxyfuel conditions in 16 min. Differential pressure profiles revealed increasing particle loads in the free board zone with increasing inlet oxygen concentration, leading to a more uniform temperature distribution throughout the CFB reactor. Flue gas analysis confirmed that Oxy-OCAC improves combustion stability compared to oxyfuel combustion with sand as bed material, enhancing oxygen distribution within the reactor. These findings demonstrate that Oxy-OCAC is a promising approach to increasing the efficiency and economic viability of oxyfuel combustion in CFB systems.

Mineral carbonation has emerged as a promising solution, permanently converting carbon dioxide (CO₂) into stable carbonates while simultaneously repurposing mine tailings for sustainable waste management. Ultramafic and mafic mine tailings, which are rich in Mg- and Ca-bearing minerals, provide abundant and reactive feedstocks for CO₂ sequestration. This review examines the chemical, mineralogical, and physical characteristics of selected tailings from nickel, asbestos, diamond, gold, iron, and platinum group metal (PGM) mines to assess their carbonation potential, and also introduces a mineral-specific analysis of mechanical activation effects across these materials. However, inherent mineralogical differences necessitate tailored activation strategies to increase CO₂ reactivity. To address this, four principal activation methods are evaluated: (1) mechanical activation, which increases the surface area and number of defect sites but has limited dissolution effects; (2) chemical activation, which increases ion availability but raises concerns over reagent costs and waste disposal; (3) thermal activation, which dehydroxylates minerals at ∼650°C to increase reactivity but is energy intensive; and (4) engineered activation, which integrates multiple approaches, such as mechanochemical, thermochemical, and external-field-assisted techniques (e.g., microwaves and ultrasound), to achieve synergistic benefits. However, challenges such as energy optimization, large-scale implementation, and sustainable reagent recovery remain, and these are critically assessed through a cross-method analysis of scalability, cost, and environmental trade-offs.

While CCS technologies demonstrate growing potential in mitigating industrial CO₂ emissions, prevailing research remains fragmented across case-specific analyses with limited theoretical integration. A critical gap persists in establishing universal thermodynamic benchmarks for energy efficiency assessment and renewable integration potential - challenges that demand coordinated scholarly attention. This study presents the thermodynamic carbon pump (TCP) framework as a foundational paradigm for structuring the CCS research agenda. Developed through systematic inquiry since 2014, the TCP framework introduces three pivotal conceptual advancements: unified thermodynamic metrics quantifying system-level energy conversion boundaries, analytical tools mapping performance optimization trajectories across adsorption-based systems, and integrative pathways for renewable energy synergies and resource recovery mechanisms. By transcending traditional case-by-case approaches, our framework enables comparative evaluation of capture systems while revealing critical interdependencies between process thermodynamics, renewable integration, and circular economy potentials. The implications of this research extend beyond technical optimization to inform three emerging research frontiers in CCS development: First, establishing standardized benchmarking protocols for cross-technology assessment. Second, developing adaptive integration models for intermittent renewable energy sources. Third, creating lifecycle assessment methodologies incorporating resource recovery economics. These research vectors collectively form an actionable agenda for advancing CCS systems toward industrial scalability and net-zero alignment.

In this study, the dissolution behavior of anorthosites collected from Yanbu, Saudi Arabia, was evaluated at field-relevant conditions. Element release rates were experimentally measured in mixed-flow reactors in aqueous fluids at pH ranging from 2 to 12 and temperatures of 60 and 120 °C. The results show that silicon release rates are consistent with those reported for intermediate plagioclase in the literature. A pronounced preferential initial calcium release was observed at all investigated conditions. Mass balance calculations suggest this preferential release is driven by calcium ion exchange with sodium ions and/or ammonium ions at the plagioclase surface. The preferential release of calcium continued throughout all experiments performed at pH greater than 3, where some experiments lasted up to 550 hours. The preferential release of calcium, combined with the observed rapid precipitation of aluminum-oxyhydroxide phases at near to neutral conditions, facilitates the formation of calcium carbonate minerals.
