This study proposes an innovative integrated power-saving system, uniting ZDG and SWH into a single model. The integration concept is rooted in leveraging the available space surrounding the daylighting device's pipe to incorporate a solar heater via a serpentine collector. The primary aim of this amalgamation is to optimize solar energy savings, minimize spatial demands, and alleviate manufacturing expenses. Moreover, the impetus behind this study stems from the recent emergence of daytime power outages in Egypt, attributed to heightened consumption surpassing production capacities. The ZDG is still not well known in Egypt. This is the only study until the year 2022/2023 in Aswan, Egypt, that analyzes the performance of this device under extreme sunlight conditions (with maximum global illumination reaching approximately 118 Klux). Across various seasons, the lighting and thermal efficacy of the current model underwent experimental testing and analysis to assess its practical utility. The integrated system effectively elevated the water temperature and achieved adequate light transmission, as indicated by the obtained results. The average transmitted indoor illumination on the work surface reached approximately 2470 lux. The reliance on electrical lighting could be mitigated for up to 5 hours. On the other hand, the highest water temperature and maximum instantaneous efficiency reached are about 70<!--> <!-->°C and 37%, respectively. Throughout the experiments, the proposed solar heater achieved a maximum daily thermal efficiency of 31.5%.

Heat pump systems come in a variety of designs, including system configurations, component (e.g., heat exchanger, compressor, working fluid) selection, and operation strategies that have a significant effect on performance and cost. In this article, we review current progress in technology development and in the methods used for techno-economic performance assessments of domestic (i.e., residential) heat pumps in the range of a few ∼kWs. The principles upon which heat pump operation and performance depend are first stated. Then, drawing from widely used performance indicators and published data on hundreds of commercially available heat pump products and components over a wide range of operating conditions, a detailed methodology is presented for obtaining performance and cost estimates. A synopsis of potential synergies with other heating, cooling and storage technologies is presented, demonstrating that appropriate integration and operation are required to maximise cost-effectiveness and emission reduction capabilities. Furthermore, whole-energy system implications of widespread heat electrification and current policy measures supporting electric heat pumps in different countries are discussed.

Thus, this market is expected to grow rapidly in the future. Today, there are a plethora of fuel cell types available on the market with a wide range of applications, including transportation, and stationary, portable, and emergency backup power. Among these fuel cells, Proton Exchange Membrane Fuel Cells (PEMFC) have the potential for use in automotive applications due to their low operating temperatures as well as high power density. Furthermore, these PEMFC power sources are also available in various power ranges and capacities for diverse vehicle applications. However, selection of optimized configurations for truck applications is a challenging task due to cost-sensitivity and competitiveness in the Indian market. Therefore, considering the above scenario, a simulation study for PEMFC performance with vehicle operating conditions is necessary to finalize the suitable fuel cell power capacity for truck applications. Based on this study, a fuel cell electric vehicle model for trucks with &gt; 30–40 tonnage applications is developed for the simulation study in this paper. Furthermore, steady state and transient simulations are conducted using GT-Suites version 2021 software on a 100 kW PEM fuel cell system. The developed model of fuel cell was found to be capable of supplying sufficient power for two lower steady-state cycles in regions with low power demand, and slightly more power was required for the third steady-state cycle. On the other hand, during the transient cycle run, the fuel cell in consideration was able to perform adequately and meet the required power demands. This study has kept other parameters constant in addition to temperature, pressure, and humidity. On the basis of this analysis, PEMFCs may find applications in automotive applications due to their low operating temperatures and high power density.</p></div>","PeriodicalId":100957,"journal":{"name":"Next Energy","volume":"5 ","pages":"Article 100167"},"PeriodicalIF":0.0,"publicationDate":"2024-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2949821X24000723/pdfft?md5=e4f9a43b380270695928398f21e4cbbe&pid=1-s2.0-S2949821X24000723-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141774570","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}

This ambitious roadmap focuses on economic diversification, global engagement, and enhanced quality of life. The electricity sector, with a 90 GW installed capacity as of 2020, is central to decarbonization, aiming for a 55% reduction in emissions by 2030. Saudi Energy Efficiency Centre’s Energy Efficiency Action Plan aims to reduce power intensity by 30% by 2030, while the NEOM project showcases a 4 GW green hydrogen facility, reflecting the country’s commitments to sustainability and technological innovation. Despite being the largest oil producer and user, Saudi Arabia must align with international CO₂ emission reduction targets. Currently, there is no state-of-the-art energy policy framework to guide a sustainable energy transition. In the academic literature, there is also lack of effort in developing comprehensive energy policy framework. This study provides a thorough and comprehensive analysis of the entire energy industry, spanning from the stage of production to consumption, incorporating sustainability factors into the wider discussion on energy policy. It establishes a conceptual framework for the energy policy of Saudi Arabia that corresponds with Vision 2030.

Results showed that for advancing the green energy transition, areas such as strategies for regional and cross-sectoral collaboration, adoption of international models, human capital development and public engagement, technological innovation, and research; and resource conservation, environmental protection, and climate change should move forward exclusively from an energy policy perspective. This article's main contribution is developing a comprehensive and conceptual policy framework for Saudi Arabia's sustainable green energy transition aligned with Vision 2030.
