Abstract Limiting global warming increasingly relies on the development of environmentally friendly CO 2 capture strategies. Crystallization is renowned for versatile separation and purification, yet traditional compound crystallization-based still necessitates intricate preparation processes, stringent reaction conditions, high regenerative energy consumption. As an ambitious sustainability goal, natural water could be used as a precursor crystallization to construct hydrogen-bonded cages capture, but main obstacles are slow kinetics low capacity. Here, water-activation-induced strategy by organic magnetic nanoparticles (Methionine@Fe 3 O 4 ) has been proposed efficient capture. Local ordering strengthened hydrophobic amino acids abundant nucleation sites provided create hotspots hydration phase transition crystal growth, with capacity 118.7 v/v (22.7 wt%). Favorable biocompatibility stable performance conducive industrial application this nanomaterial, excellent recyclable property enables simple from clean water. This demonstrates extraordinary potential compared state-of-the-art systems, thus providing inspiration sustainable storage zero resource depletion (ZRD).

Energies, Год журнала: 2025, Номер 18(4), С. 942 - 942

Опубликована: Фев. 16, 2025

Climate change has become one of the most pressing global challenges, with greenhouse gas emissions, particularly carbon dioxide (CO2), being primary drivers warming. To effectively address climate change, reducing emissions an urgent task for countries worldwide. Carbon capture, utilization, and storage (CCUS) technologies are regarded as crucial measures to combat among which ocean CO2 sequestration emerged a promising approach. Recent reports from International Energy Agency (IEA) indicate that by 2060, CCUS could contribute up 14% cumulative reductions, highlighting their significant potential in mitigating change. This review discusses main technological pathways sequestration, including oceanic water column oil gas/coal seam geological saline aquifer seabed methane hydrate sequestration. The current research status challenges these reviewed, particular focus on offers density approximately 0.5 1.0 Gt per cubic kilometer hydrate. article delves into formation mechanisms, stability conditions, advantages hydrates. via hydrates not only high but also ensures long-term low-temperature, high-pressure conditions seabed, minimizing leakage risks. makes it technologies. paper analyzes difficulties faced technologies, such kinetic limitations monitoring during process. Finally, this looks ahead future development providing theoretical support practical guidance optimizing application promoting low-carbon economy.

With the continuous growth of global energy demand and gradual depletion traditional fossil reserves, natural gas hydrates have attracted widespread attention as a potential clean source due to their vast reserves wide distribution. Although various extraction methods, including depressurization, thermal stimulation, chemical inhibitors, displacement been proposed, there are still challenges, such low efficiency, poor sustainability, high costs, making it difficult achieve large-scale engineering applications. Among these, use gases CO2 for can both develop hydrate resources sequester CO2, achieving win–win situation resource development greenhouse reduction. This paper provides detailed review multi-gas technology hydrates, systematically summarizes latest progress in thermodynamic kinetic studies, analyzes technical advantages feasibility combining methods with techniques, explores effects mixtures, N2, H2, ratios on efficiency. Finally, this challenges faced by offers future research directions promote hydrates.

Depressurization-Assisted CO₂/N₂ Replacement for Methane Recovery from Hydrate-Bearing Clayey Sediments

Energy & Fuels, Год журнала: 2025, Номер unknown

Опубликована: Март 5, 2025

Natural gas hydrates (NGHs) are regarded as a secure and efficient renewable energy resource. Recovering methane (CH4) by injecting carbon dioxide (CO2) into NGHs is an innovative method for production greenhouse gases control. However, the replacement injection of CO2 CH4 recovery was constrained mass transfer permeability limitations, leading to poor efficiency rate. Herein, depressurization-assisted CO2/N2 proposed enhance sequestration. In this study, coupled experiment integrating mixed staged depressurization conducted in hydrate-bearing clayey (montmorillonite) sediments using custom-designed triaxial pressure reaction apparatus. The effects pressure, temperature, time were systematically analyzed. results indicate that there substantially enhanced sequestration compared condition without assistance, with remarkable increase from 21 85.7% 45.4 68.3%, respectively. integration effectively overcame physical barriers between hydrate phases, resulting 67.6% enhancement significantly accelerated postdepressurization study provide insight exploring low-carbon
