Key findings indicate that CH<sub>4</sub>/CO, a mixture of 2 supercritical gases at room temperature, shows modest adsorption selectivity of around 4, even at elevated pressures of 20 MPa. In contrast, the C<sub>2</sub>F<sub>6</sub>/N<sub>2</sub> mixture, consisting of supercritical N<sub>2</sub> and C<sub>2</sub>F<sub>6</sub> near its critical temperature, exhibits significantly higher selectivity, reaching tens to hundreds. The SO<sub>2</sub>/CO<sub>2</sub> mixture, with both gases in a subcritical state at room temperature, displays intermediate selectivity between the other 2 systems. Our simulations revealed that the adsorption selectivity for CH<sub>4</sub>/CO and C<sub>2</sub>F<sub>6</sub>/N<sub>2</sub> mixtures displays distinct single- and double-peaked trends with varying pore widths under medium to high pressures, corresponding to monolayer and bilayer adsorption phenomena. The SO<sub>2</sub>/CO<sub>2</sub> system, however, presented a more intricate adsorption mechanism, potentially involving 3-layer molecular adsorption within the pores. Expanding our investigation to 276 mixtures, we discovered an important trend: a higher ratio of critical temperatures between mixture components correlates with increased adsorption selectivity and simplified separation processes. Intriguingly, when this ratio approaches unity, separation difficulty escalates. Additionally, we identified a significant linear relationship between adsorption selectivity and the ratio of adsorption heats at low pressures (0.1 MPa) for a pore width of 0.8 nm, underscoring the impact of thermodynamic properties on separation efficacy. These insights are crucial for the development of energy-efficient gas separation materials, which are vital for applications such as natural gas purification and carbon capture and storage, contributing to a sustainable energy future.</p></div>","PeriodicalId":100957,"journal":{"name":"Next Energy","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2949821X24000930/pdfft?md5=9d40c8a9279634306cb44f9b73ce7697&pid=1-s2.0-S2949821X24000930-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142164664","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}

In this regard, this review presents a thorough examination of the latest advancements in enhancing photovoltaic (PV) systems, with a focus on cooling techniques, concentration methods, spectral splitting filtering, and tracking systems. A comprehensive analysis of both passive and active cooling technologies was presented, where cooling improves the efficiency of the panel to up to 25%, in addition to the possibility of integrating PV modules with thermal collectors to exploit the wasted heat in what is known as Photovoltaic/thermal systems (PV/T). Additionally, the study explores various types of concentrated PV (CPV) systems, such as flat concentrators, compound parabolic concentrators, and Fresnel lenses, which can lead to 10% increase in the panel efficiency. The paper also introduces the concept of spectral splitting filtering, covering reflective and absorptive methods to optimize solar energy utilization, which is considered a new technology cooling method. Furthermore, it delves into tracking systems for PV modules which can cause an increase in efficiency about 20%. The novelty of this review lies in its up-to-date coverage of the latest research and advancements in PV system enhancement.

However, the advancement of LIB technology is hindered by the phenomenon of thermal runaway (TR), which constitutes the primary failure mechanism of LIBs, potentially leading severe fires and explosions. This review provides a comprehensive understanding of the TR mechanisms in LIBs, which vary significantly depending on the battery’s materials. Extensive research has been conducted on the component materials of LIBs, the causes triggering TR, and the mechanisms underlying TR in laboratory settings. Yet, further research to fully understand and mitigate TR is necessary as it is a highly complex process that is readily influenced by both external conditions and internal reactions. For LIBs composed of different materials, the processes and mechanisms underlying TR exhibit significant variations. Therefore, this review emphasizes the need to study various battery cells to gain a comprehensive understanding of the TR mechanisms. The focus of this review lies in elucidating the diverse TR mechanisms, preventive methods, and highlighting recent key progresses in research aimed at improving the safety of LIBs.

At the same time substantial leakages of natural gas from hydrates contributes significantly to climate changes. One of the most important reasons for these natural gas fluxes is leakage of seawater in to the hydrates from seafloor, through fracture systems. Hydrate dissociates if surrounding seawater is less than hydrate stability limit. Another interesting aspect of natural gas hydrates is the potential for safe CO<sub>2</sub> storage. These different aspects of hydrates in natural sediments put demands on thermodynamic models. In addition to accurate description of pressure temperature hydrate stability there also a need to describe hydrate dissociation in concentration gradients towards surrounding water or surrounding gas as two examples. In this work we present new experimental data and an extensive thermodynamic model for hydrate. In contrast to conventional thermodynamic models for hydrate the model is consistent since all thermodynamic properties are derived from the Gibbs free energy. In this work we examine mixtures of CH<sub>4</sub>, C<sub>2</sub>H<sub>6</sub>, N<sub>2</sub>, CO<sub>2</sub> from the China Sea and some synthetic mixtures, using this model. Maximum CO<sub>2</sub> content in these mixtures are 60 mol% and the rest is dominated by CH<sub>4</sub>. Agreement between experimental data and model calculations are generally good and average deviations are below 5.5% for all the systems and conditions examined. Another aspect of the model is the ability for incorporation of effects of mineral surfaces. Specifically it is illustrated that adsorption of water on rust dominates liquid water drop out from gas as compared to water dew-point. Production of natural gas with such high CO<sub>2</sub> content requires a strategy for CO<sub>2</sub> separation and storage. It is proposed that the CH<sub>4</sub> is separated from the C<sub>2</sub>H<sub>6</sub>, CO<sub>2</sub> and N<sub>2</sub> and cracked to H<sub>2</sub> and CO<sub>2</sub> using steam. Thermodynamic analysis indicates a significant potential for safe CO<sub>2</sub> storage in natural gas hydrate and H<sub>2</sub> as the only export product.</p></div>","PeriodicalId":100957,"journal":{"name":"Next Energy","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2949821X2400084X/pdfft?md5=266f79a863d4e1ecd73da3f5956a0086&pid=1-s2.0-S2949821X2400084X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142098526","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}
