Biocomposites made of natural cotton fiber with white and four distinct colors, such as red, yellow, blue, and black, were developed employing a compression molding technique. Among the studied composites, the white cotton composite owing to reflective surface has the lowest thermal conductivity of 0.0687 W/m·K, which was the maximum for its black counterpart with the value of 0.0823 W/m·K. The white composite, in contrast, exhibited higher conductive heat resistance (0.0582 m<sup>2</sup>·K/W) than the black ones (0.04862 m<sup>2</sup>·K/W). The evaluation of the radiative heat resistance using an incandescent lamp and sunlight showed the superior resistance of white composite to radiant heat transfer due to its high reflectance of electromagnetic radiation, making it an effective reflector and heat insulator material for thermal energy conservation. Additionally, the thermogravimetric analysis revealed adequate thermal stability with a similar trend in the degradation pattern of composites at elevated temperatures, confirming a negligible impact of color on thermal stability. The overall outcomes of this study suggest fiber-reinforced composites with reflective (white) surfaces can considerably resist the transfer of conductive and radiative heat than colored cotton materials and, therefore, can be employed as better heat-insulating panels in buildings for lowering thermal loads to maintain favorable indoor temperature.</div></div>","PeriodicalId":37131,"journal":{"name":"Energy Conversion and Management-X","volume":"26 ","pages":"Article 100926"},"PeriodicalIF":7.1,"publicationDate":"2025-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143419710","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}

The same routes have been considered in two different seasons (March 2024 and August/September 2024), to underline the effect of air and seawater temperatures on the overall performance of the integrated system. The steady-state thermodynamic analysis has been carried out using the commercial software Thermoflex. The results of the analysis highlighted that the overall efficiency of the system can vary up to 11 % in the same location, in different seasons and can reach a value closed to 49 %, dropping to 42 % in the worst-case scenario.

Economic analysis identifies high operational costs and resource intensity as major barriers to sustainability. Socially, while LNG shipping creates employment opportunities, it raises concerns about fair compensation practices. Sensitivity analysis identifies regasification as a critical stage where targeted improvements can significantly reduce emissions. Furthermore, optimizing vessel design and LNG shipping routes offers the potential for minimizing environmental impacts. This study recommends strategic actions such as enhancing shipping logistics, advancing liquefaction technologies, and integrating renewable energy to improve the sustainability of LNG-based electricity generation.

First, a mechanistic/semi-empirical fuel cell model is established based on parameters with direct physical meaning. This model effectively illustrates the internal mechanisms of the fuel cell, providing deeper insights into its operation. Second, a complete dynamic model of a fuel cell power system is developed, comprising all necessary components and being capable of independently powering an external load or interacting with other systems. Third, by employing a Nonlinear Autoregressive model with External Input (NARX), a metamodel of the fuel cell system is created, achieving significantly improved computational efficiency while retaining essential knowledge of key phenomena. When comparing the simulation results of the NARX metamodel with those from the original mathematical model, the coefficient of determination (R<sup>2</sup>) exceeds 0.98 in post-startup conditions. Moreover, the computational speed increases at least 90-fold.

As a result, the use of seawater desalination units can solve the above basic problem. The use of fossil fuels is no longer a suitable solution for providing energy for desalination of sea water due to the increase in the emission of greenhouse gases, including carbon dioxide. On the other hand, the use of solar energy, due to its availability and cleanliness, is a promising solution for desalination of sea water. Integration of renewable systems with desalination units can solve the shortage of fresh water in the world and make the systems sustainable. The most important desalination processes include membrane desalination (for example, reverse osmosis (RO)) and thermal desalination (for example, multistage flash (MSF) and multi effect distillation (MED)).
