Unlike conventional steam curing, ACC introduces controlled CO₂ exposure during the curing stage of freshly formed masonry products, enabling strength development and permanent carbon sequestration. This paper reviews the current research on ACC of load-bearing and non-load-bearing CMUs, including manufacturing methods, mix design, curing parameters, CO₂ uptake, mechanical properties, durability, and industrial implementation. Evidence from laboratory-scale specimens, and pilot- and full-scale block production is examined to identify the governing mechanisms and practical performance trends. The reviewed studies show that ACC can permanently sequester approximately 9–25% of cement mass as CO₂ in OPC-based systems, while reducing curing-energy demand from approximately 2500 kJ/block for steam curing to about 500 kJ/block. Across the literature, the optimum moisture condition consistently corresponded to approximately 4–6% residual moisture or 35–50% mixing-water loss, confirming that moisture pre-conditioning is the dominant process variable controlling carbonation efficiency. The reviewed studies also demonstrate that low-pressure carbonation curing, typically about 0.1–0.5 bar above atmospheric pressure and 2–6 h duration, is generally sufficient for practical masonry production. ACC is shown to provide substantial early-age strength gain and CO₂ uptake, although maximum sequestration and maximum strength do not necessarily coincide under the same curing conditions. The review also shows that post-carbonation hydration is important for later-age performance, and that ACC generally improves dimensional stability and reduces water transport, while long-term durability evidence remains comparatively limited. Alternative and low-clinker binder systems, including recycled-aggregate fines, slag-based, and waste-derived masonry products, further demonstrate the broader potential of ACC, but their scale-up and standardization are less mature than those of OPC-based systems. Overall, ACC is a feasible alternative to steam curing for masonry production. ACC can reduce energy consumption and permanently store CO₂ in masonry products. However, wider industrial application still requires standardized curing methods, long-term durability verification, and optimization of plant-scale curing processes.</div></div>","PeriodicalId":9387,"journal":{"name":"Carbon Capture Science & Technology","volume":"20 ","pages":"Article 100680"},"PeriodicalIF":10.2,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148854359","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review systematically compares the three main electrified heating approaches currently investigated for post-combustion CO₂ capture: Resistive heating (RH), Induction heating (IH), and Microwave heating (MWH). To improve comparability across the fragmented and predominantly laboratory-scale eTSA literature, publications of comparable boundary conditions were analyzed using homogeneous evaluation criteria including working capacity, CO₂/N₂ selectivity, heating rate, temperature homogeneity, regeneration energy and electrical and thermal energy efficiencies. Among the reviewed adsorbents, physisorbents dominated the current eTSA literature, particularly metal-organic frameworks (MOFs), zeolites, and activated carbons (ACs). Mg-MOF-74 and Mg-Gallate exhibited the highest working capacities, followed by the zeolites 13X and NaUSY, while AC offers direct applicability for RH and MWH because of its conductive and microwave-responsive properties. However, humidity sensitivity remains a major limitation for high adsorption capacity physisorbents. All reviewed electrified heating approaches achieved substantially higher heating rates than conventional conductive wall heating or hot gas purge systems. RH has a potentially very high overall energy efficiency, although homogeneous current distribution remains challenging. IH provides high flexibility in adsorbent selection through magnetic heating additives and offers strong potential for homogeneous internal heating, while efficient magnetic field coupling remains the key challenge for energy-efficient operation. MWH enables extremely rapid heating without necessarily requiring additional heating materials but faces challenges regarding temperature homogeneity and electric-to-thermal energy efficiency. Overall, all electrified approaches still face important scale-up challenges regarding heat and field distribution, and electrical-to-thermal energy efficiency. This review highlights the strong potential of eTSA for flexible and intensified CO₂ capture while identifying humidity-tolerant adsorbents, cyclic stability, heat-management optimization, and realistic process-scale evaluation as key priorities for future research and industrial implementation.</div></div>","PeriodicalId":9387,"journal":{"name":"Carbon Capture Science & Technology","volume":"19 ","pages":"Article 100636"},"PeriodicalIF":0.0,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148167985","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}

Polymer-based membrane separations present a promising solution; however, their practicability remains limited by their inherently low H₂ permeability and modest H₂/CO₂ selectivity. This study presents a novel approach that incorporates supramolecular sulfobutyl-ether-beta-cyclodextrin (SBECD) molecules into a polybenzimidazole (PBI) matrix to fabricate high-performance PBI-SBECD membranes. The uniformly dispersed bulky SBECD structure in PBI not only disrupts the close chain packing of PBI but also increases the overall fractional free volume (FFV). This “host-like” modulation of free volume generates additional molecular sieving sites that favor smaller H₂ molecules over larger CO₂, thereby improving H₂/CO₂ separation performance. The resulting membranes exhibited significance enhancements in both H₂ permeability and H₂/CO₂ selectivity compared to the original PBI. In particular, the PBI-SBECD (6%) membrane, prepared with a SBECD loading of 6 wt.%, achieved an H₂ permeability of 13.56 Barrer and an H₂/CO₂ selectivity of 20.23 tested at 50 ° C and 6 atm. It is a 180% increase in H₂ permeability and a 121% enhancement in H₂/CO₂ selectivity compared to the pristine PBI membrane. It also exceeds the 2008 Robeson upper bound for H₂/CO₂ separation. Moreover, its mixed-gas performance for H₂/CO₂ separation also remained significantly above the upper bound and was comparable to the leading PBI-based and other representative membranes reported in literature, underscoring the effectiveness of the SBECD supramolecular cavities in facilitating size-sieving transport pathways. The design strategy proposed in this study would establish a solid technical foundation for the molecular integration of cyclodextrin with PBI and offers an innovative route to fabricate next-generation polymeric membranes for highly effective H₂/CO₂ separation at a moderate temperature.</div></div>","PeriodicalId":9387,"journal":{"name":"Carbon Capture Science & Technology","volume":"19 ","pages":"Article 100639"},"PeriodicalIF":0.0,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148167866","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}

For CO₂-N₂ mixtures at 20°C, with CO₂ inlet mole fractions between 0.09 and 0.35, the energy requirement of the new process, related to vacuum pumping, is between 0.29 and 0.98 GJ per ton of CO₂ captured. This is significantly lower than the reference technology for treating atmospheric flue gases, namely chemical absorption, which requires between 3.0 and 5.5 GJ per ton of CO₂ captured. Refrigeration at 5 °C further reduces energy demand by up to 27%. Considering the geometry of the commercial Liqui-Cel™ EXF hollow fiber membrane modules, the volumetric footprint of the equipment is similar to that used for chemical absorption. The specific energy demand of the process for biogas treatment is between 0.044 and 0.052 kWh per Nm³ of raw biogas. This value is approximately four times lower than the energy demand of current biogas upgrading technologies, which is between 0.2 and 0.3 kWh per Nm³ of raw gas.

Zeolite–polymer composites are emerging as a robust engineering solution to this bottleneck, synergistically coupling the high density of crystalline adsorption sites and molecular sieving of zeolites with the tunable moisture tolerance and reversible chemisorption of polymers. This comprehensive review critically evaluates recent advances in the integration of natural and synthetic zeolites with diverse polymer matrices, including chitosan, polyethyleneimine (PEI), cationic polyelectrolytes, and polyacrylates. We systematically analyze how polymer chemistry, interfacial loading, and spatial distribution govern crucial performance metrics: pore preservation, diffusion resistance, and cyclic stability.

Furthermore, optimal polymer impregnation markedly enhances high-temperature performance; for example, MCM-41-PEI architectures (50 wt% loading) deliver 4.89 mmol g⁻¹ at 348 K, representing a 24-fold increase in capacity over the raw support.
