However, it suffers from high consumption of high-grade energy and the generation of large amounts of high-concentration brine, which is harmful to the environment. This study provided an innovative solar-powered hybrid desalination plant that integrates RO, an absorption (AB) desalination-cooling system, and a humidification-dehumidification (HDH) system for mitigating water shortage, optimizing energy utilization, and reducing carbon emissions. The rejected brine from the RO system is treated further by passing it through the AB and HDH desalination systems to produce additional fresh water and treat the rejected brine. In addition, the feed RO brine is passed through the absorber before entering the HDH system, which eliminates a separate heat source to preheat the fluid entering heat the fluid filling the humidifier. In this study, two configurations of hybrid systems were proposed and compared. In the first configuration (RO-AB-HDH), a simultaneous drinking water and cooling effect (from the AB system) can be obtained. In the second configuration, an energy recovery scheme is used between the condenser and evaporator (HR) of the AB to enhance the evaporation rate and the water production rate. Numerical models were developed to simulate and evaluate the performance and economic viability of the proposed systems for various operating conditions. Results showed that the proposed hybrid systems significantly improve the quality and quantity of desalinated water, as well as reduce the cost of freshwater, compared to the stand-alone RO cycle. For instance, the product freshwater salinity obtained by the proposed systems is decreased by 63 %, compared to the RO system for an applied pressure of 70 bar and feed salinity of 50,000 ppm. The first configuration is the most cost-effective at a high salinity of 45,000–50,000 ppm when the system is driven by solar energy with 2.2 $/m³ with an additional free-cooling effect of 17.6 kW at 85 °C. The second configuration is more effective when only a large amount of desalinated fresh water is needed.</div></div>","PeriodicalId":56019,"journal":{"name":"Sustainable Energy Technologies and Assessments","volume":"81 ","pages":"Article 104451"},"PeriodicalIF":7.1,"publicationDate":"2025-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144631776","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Simultaneously, the global seaweed industry has become increasingly competitive, which demands technological advancements across processing stages, especially in drying. Here, we developed a novel industrial-scale fixed-bed dryer (FBD) for ATCC and assessed its feasibility to address these issues. Several critical parameters, including product quality, drying performance, and CO₂ emission reduction, were evaluated to determine the novel FBD’s viability compared to a conventional FBD. Drying kinetics were also analyzed using 24 thin-layer drying models to identify the most appropriate model for describing ATCC drying behavior with the novel FBD. The results of this study indicated that the novel FBD effectively dried ATCC to a quality suitable for milling. The Improved Midilli-Kucuk and Hii et al. models provided the best fit for describing the drying kinetics. Additionally, the novel FBD reduced drying time by one hour, decreased specific energy consumption by 60%, improved drying efficiency by over 150%, and lowered drying costs by 55%. Consequently, it emitted 60% less CO₂ than the conventional FBD. In conclusion, this study successfully developed a novel FBD that addresses the critical challenges of high energy consumption and CO₂ emissions in ATCC drying and also offers multiple benefits for the global seaweed industry, aligning with the objectives of SDG 7, SDG 9, and SDG 13.</div></div>","PeriodicalId":56019,"journal":{"name":"Sustainable Energy Technologies and Assessments","volume":"81 ","pages":"Article 104453"},"PeriodicalIF":7.1,"publicationDate":"2025-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144613925","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results indicated that WODR exhibited a higher coking tendency than waste oil, primarily attributed to the obvious heavy fraction content (∼42 %), lower H/C (∼1.81), and decreased CH₂/CH₃ (∼1.416). The heating rate exerted an obvious influence on pyrolytic behaviors, involving threshold, peak, and termination temperatures, and maximum mass loss rate.

However, the success of AVS projects depends on inclusive geospatial planning to identify optimal development sites that balance the requirements of both complementary applications—energy and agriculture. This review offers a critical analysis of spatial investigations conducted to date in the AVS field, preceded by an overview of the system types and their potential. The applied decision criteria and spatially based analytical methods, along with their strengths and weaknesses, are inventoried, analyzed, and discussed. The findings indicate that most spatial studies on AVS have been concentrated in the Northern Hemisphere and have predominantly relied on traditional multi-criteria decision-making models, with a notable absence of AI-driven planning solutions.

Traditional transient stability assessment methodologies, which rely on time domain simulations and energy function-based approaches, face significant limitations in computational efficiency and real-time applicability. To address these challenges, this paper proposes a novel dual-phase framework that integrates Long Short-Term Memory (LSTM) networks and a modified Transformer architecture for enhanced transient stability evaluation. In the first phase, an LSTM-based trajectory reconstruction module is employed to extrapolate complete 5-second dynamic trajectories from initial measurements of 0.5 s post-fault. This addresses the critical issue of temporal data insufficiency during the early stages of system perturbations, enabling accurate representation of electromechanical transients. The second phase employs a Transformer classifier, which processes the reconstructed trajectories to assess system stability. The Transformer’s architecture incorporates tailored positional encoding to align with the frequency and timescale characteristics of system dynamics, while its self-attention mechanism facilitates the extraction of global temporal patterns essential for stability classification. A case study on the IEEE 39-bus system demonstrates the efficacy of the proposed framework. Within the critical post-fault assessment window, the method achieves an accuracy of 99.6%, significantly outperforming conventional methods in both computational efficiency and classification accuracy.</div></div>","PeriodicalId":56019,"journal":{"name":"Sustainable Energy Technologies and Assessments","volume":"81 ","pages":"Article 104432"},"PeriodicalIF":7.1,"publicationDate":"2025-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144581291","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
