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. Our findings ultimately advocate for paradigm-shifting research strategies that bridge thermodynamic fundamentals with sustainable systems engineering in carbon management.</div></div>","PeriodicalId":9387,"journal":{"name":"Carbon Capture Science & Technology","volume":"15 ","pages":"Article 100434"},"PeriodicalIF":0.0,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143900040","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}

Using hierarchical mesoporous silica (HMS) as the support, a dual-functional modification approach combining aminopropyltrimethoxysilane (APTMS) and butyltrimethoxysilane (BTMS) grafting with tetraethylenepentamine (TEPA) impregnation was employed to construct an efficient CO₂ adsorption system with dual active sites. APTMS and BTMS were alternately grafted onto the HMS <em>via</em> siloxane bonds, resulting in a structure with varying polarities. The strong polarity of TEPA interacts simultaneously with the terminal groups of APTMS and BTMS, facilitating the uniform dispersion of TEPA within the material. The optimized HMS-AB-70T adsorbent exhibited a dynamic CO₂ adsorption capacity of 5.34 mmol <em>g</em>⁻¹ at 70 °C, with a reduction of 9.8 % in adsorption capacity after 10 cycles. In a humid environment, its performance was further enhanced to 5.89 mmol <em>g</em>⁻¹.

By adjusting the hydrophilic-lipophilic balance of the P123 template, a hierarchical mesoporous structure of HMS (∼6 nm and ∼10 nm) was successfully achieved, promoting rapid mass transfer and providing abundant adsorption sites.

Carbon capture and utilization (CCU) is emerging as a key approach to closing the carbon cycle, with membrane-based CO₂ absorption reducing energy demands during the capture process. However, conventional membranes rely on fossil-based polymers and toxic solvents, raising concerns about their environmental impact. This study introduces a bio-based membrane contactor for CCU applications, utilizing polylactic acid (PLA), a renewable and sustainable biopolymer. The influence of polymer concentration, molecular weight, crystallinity, solvent type, and recycling on membrane morphology and CO₂ capture performance was investigated. The PLA membranes exhibited asymmetric morphologies ranging from finger-like to sponge-like structures. Higher polymer concentration and molecular weight increased sponge-like morphology, while solvents with stronger solvating power promoted finger-like structures. Interestingly, initial polymer crystallinity did not influence membrane morphology, but crystallinity induced during synthesis supported sponge-like structures. Membranes made with high molecular weight PLA and wide finger-like morphologies demonstrated stable CO₂ capture performance (2.36 × 10^-⁵ m³/m²·s), comparable to commercial PVDF membranes (2.47 × 10^-⁵ m³/m²·s). Furthermore, recycled membranes retained CO₂ capture performance over five cycles (2.04 – 2.26 × 10^-⁵ m³/m²·s).

In this study, the fundamentals of designing and fabricating composite hollow fiber membranes consisting of an inner polyethersulfone (PES) substrate, a polydimethylsiloxane (PDMS) gutter layer, and an outer Pebax selective layer were revealed for CO₂/N₂ separation. The resultant Pebax/PDMS/PES composite hollow fiber membranes possess a CO₂ permeance of 1253 GPU and an ideal CO₂/N₂ selectivity of 34.9 at 0.1 MPa and 25 °C. They have a comparable CO₂/N₂ selectivity but a much higher CO₂ permeance of 1–2 times than other Pebax based composite hollow fiber membranes in literature. The much higher CO₂ permeance demonstrates the effectiveness of the proposed strategies to design multi-layer composite hollow fiber membranes for CO₂ capture. Two major challenges have been innovatively overcome when developing these composite membranes. Namely, the diminish of PDMS intrusion during its coating on PES substrates and the hydrophilization of inherently hydrophobic PDMS surfaces for the Pebax coating. The former was solved by optimizing the spinning conditions such as air gap distance, coagulation temperature, and bore fluid composition to design the substrates with a dense outer surface and a porous inner surface, thus minimizing PDMS intrusion and gas transport resistance. The latter was overcome using plasma to improve the wettability of PDMS surfaces.

The current study evaluated CO₂ storage infrastructure in Northern Thailand’s onshore saline formations to support BECCS deployment and contribute to the nation’s decarbonization goals under its Nationally Determined Contribution. The geological storage potential, CO₂ plume migration, storage containment, and cost estimates of the Lampang and Nong Bua Basins were comprehensively assessed. Numerical simulations were performed to evaluate storage capacities and containment mechanisms, incorporating reservoir heterogeneity and geomechanical constraints. Results indicated a combined dynamic storage capacity of 29 Mtpa, with the BECCS cluster designed to store 10 Mtpa: 4 Mtpa allocated to the Nong Bua Basin and 6 Mtpa to the Lampang Basin. The Lampang Basin also offered excess capacity to accommodate 15 Mtpa from the coal-fired power plant located in Lampang. Stratigraphic heterogeneity of reservoir was found to enhance storage containment through improved residual and solubility trapping, although mineral trapping remained negligible. The levelized cost of CO₂ storage was estimated at 7.99 USD/tonne for a 35-year injection period and 8.23 USD/tonne for a 25-year injection period, with operational costs accounting for more than half of the total cost. These estimates align with global benchmarks, validating the methodology while reflecting Thailand-specific conditions. The current work highlights the feasibility of BECCS deployment in Thailand, presenting a scalable and cost-effective solution for CO₂ sequestration.

This review analyses 4,4′-(hexafluoroisopropylidene) diphthalic anhydride (6FDA)-based polyimides, emphasising their vital role in CO₂ gas separation. It discusses recent advancements and highlights their characteristics: high free volume, thermal stability, and chemical resistance, making them ideal for efficient gas separation. The review also covers fabrication methods for 6FDA-derived membranes, including composite and hybrid types with superior performance. It further examines recent advancements in 6FDA-based polymeric membranes, particularly mixed matrix membranes (MMMs) and hybrid architectures, with a focused discussion on polymer modifications such as thermal rearrangement and cross-linking, as well as the strategic integration of advanced fillers, including metal-organic frameworks (MOFs), zeolitic imidazolate frameworks (ZIFs), and ionic liquids (ILs). These advancements collectively contribute to enhanced membrane performance and expand their potential applications in gas separation technologies. For instance, adding 20 wt. % ZIF-67 to 6FDA-Durene significantly increased CO₂ permeability from 669.12 to 1529.86 Barrer. However, this enhancement came at the cost of a slight decrease in CO₂/N₂ and CO₂/CH₄ selectivities. In contrast, incorporating 20 wt. % [Emim][Tf₂N]@ZIF-67 improved CO₂ permeability by 33 %, while also increasing CO₂/N₂ selectivity from 25 to 28 and CO₂/CH₄ selectivity from 24 to 28. This highlights the superior performance of hybrid membranes over other composite formulations. The review highlights molecular simulations' critical role in revealing atomistic interactions and optimising filler-polymer interfaces, addressing scalability issues in experimental separations. These simulations provide insights for developing high-performance membranes.
