This work critically examines the current landscape of solid sorbents for DAC, focusing on their performance, durability, and environmental impact. Key sorbent classes — amine-functionalized materials, carbonates, zeolites, and metal-organic frameworks — are evaluated in terms of CO₂ uptake, energy requirements, and life cycle emissions. A novel exergetic efficiency metric is introduced, incorporating sorbent degradation to better reflect real-world performance. Structured supports such as laminates and monoliths are discussed for their role in enhancing mass transfer and reducing pressure drop, though often at increased cost and environmental burden. Life cycle assessment (LCA) results highlight that energy consumption dominates DAC’s carbon footprint, with sorbent-related impacts becoming significant only for short-lived or energy-intensive materials. Emerging materials like hydroxylated activated carbon, along with alternative processes such as moisture swing adsorption and electrochemical DAC, offer promising pathways to reduce energy demand and improve sustainability. The work underscores the need for integrated assessments that link sorbent properties, process design, and environmental metrics from early development stages. Future research should prioritise sorbent longevity, comprehensive kinetic data, and inclusion of support structures in LCA models to enable cost-effective and climate-positive DAC deployment.</div></div>","PeriodicalId":292,"journal":{"name":"Current Opinion in Chemical Engineering","volume":"50 ","pages":"Article 101195"},"PeriodicalIF":6.8,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145412648","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It serves two key roles: (a) when integrated with Carbon Capture and Storage (DAC-CCS), it enables permanent CO₂ removal to offset emissions from hard-to-abate sources like aviation; and (b) when combined with Carbon Capture and Utilization (DAC-CCU), it provides non-fossil CO₂ for producing defossilized fuels and zero-carbon chemicals. To fulfill these roles, DAC systems must be scalable and economically viable. While academic studies often focus on assessing sorbent performance under a limited range of weather conditions and for limited periods, we advocate that industrial scale deployment demands DAC systems with additional key features such as low pressure drop, high reliability for long periods (years) in a wide range of weather conditions (temperature, relative humidity), resistance to fouling from particulates in air, and without loss of performance by reingestion of CO2 depleted air. These key features are more commonly addressed in patent literature by companies nearing commercialization rather than in academic publications. Moreover, DAC technologies must be capital-efficient, and use low-cost, recyclable sorbents.</div></div>","PeriodicalId":292,"journal":{"name":"Current Opinion in Chemical Engineering","volume":"50 ","pages":"Article 101190"},"PeriodicalIF":6.8,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145263086","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While experiments and traditional physics-based models have advanced our understanding, their cost and complexity limit the study of large-scale systems and applications. Data-driven modeling has emerged as a promising alternative, enabling efficient prediction of transport–reaction phenomena across scales. This review categorizes state-of-the-art approaches into three main groups: reduced order models that simplify high-fidelity simulations, hybrid physics-data approaches that couple data models with physics-based simulations, and fully data-driven frameworks that leverage operator-learning and neural surrogates. Particular emphasis is placed on cross-scale learning for developing data models, as well as on emerging architectures such as PINN-based frameworks, neural operators, and transformer-inspired GPT models. Challenges in data availability, interpretability, and geometry transfer are discussed, along with future opportunities for reactor digitalization, adaptive control, and decarbonization through multiscale integration of data-driven models.</div></div>","PeriodicalId":292,"journal":{"name":"Current Opinion in Chemical Engineering","volume":"50 ","pages":"Article 101193"},"PeriodicalIF":6.8,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145412647","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
