Up to now, great effort is being made to develop a new material for STWS with low cost, provides good cycling stability and operates under mild conditions. In this paper, a thermodynamic study of different types of metal oxides including pure metal oxide, pure spinel metal oxides, and ferrite mixed oxides) was recoded to screen the most promising pairs for hydrogen production via STWS method.The obtained results showed the lowest reduction temperature (TR = 390 °C) related to the redox couple SrO2/SrO. However, the oxidation remains not thermodynamically feasible with water or using a strong oxidant such as NaOH. Besides, the couple Sb2O5/Sb2O3 shows good results in terms of reduction and oxidation temperatures (830 °C and 510 °C respectively). In addition, for spinel materials such Co3O4 and Mn3O4 the oxidation is only possible when NaOH is used. Finally, for ferrite systems and especially for NiFe2O4, a reduction temperature of 835 °C has been reported while more efforts should be directed to enhance the oxidation reaction feasibility of ferrite spinel systems.","PeriodicalId":361856,"journal":{"name":"2021 9th International Renewable and Sustainable Energy Conference (IRSEC)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117135719","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this regard, it is essential to know and understand the ground temperature profile to design shallow geothermal applications and estimate the energy contribution. Many parameters influence the ground temperature profile, such as soil properties, surface cover, soil moisture, degree of compaction...etc. The variation of these parameters affects the damping depth of the annual fluctuation of ground temperature and the thermal diffusivity. Accordingly, the present study investigates experimentally the ground temperature profile subjected to the variation of two selected parameters on the ground response time and the damping depth. These parameters are solar radiation and ground humidity. The ground temperatures were measured and then used to present the temperature distribution profiles. The measurement site is in Madinah (lat. of 24.5° N and long. of 39.5° E), KSA, characterized by a hot and arid climate, where the temperature in summer exceeds 48.0 °C. A well of 14 m depth and 7.5 cm diameter is drilled in the site, and 15 thermocouples (T-type) are used to measure the ground temperature at different depths. Results show that the ground temperature as a geothermal energy source is sensitive to solar radiation and soil humidity, especially near the ground surface. These parameters can influence the design and operation of EAHE.","PeriodicalId":361856,"journal":{"name":"2021 9th International Renewable and Sustainable Energy Conference (IRSEC)","volume":"436 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123576228","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although photovoltaic systems do not require deep maintenance, the efficiency of photovoltaic modules is decreased from 0.40 to 0.50% for each °C gained in the operating temperature. Thus, depending on the environmental conditions, a cooling system is necessary to increase the durability and efficiency of the project. The present work analyzes the generation of an installed photovoltaic module (PV module) and performs a theoretical and numerical study for the system's thermal behavior, depending on the experimental conditions, including the impact of adding extended surfaces (fins) on the average module temperature. The passive cooling system consists of 36 L-shaped aluminum fins arranged in the central region on the backside surface of the PV module. The theoretical model for predicting the temperature of the PV module without a coupled cooling system was satisfactory compared with the values obtained experimentally; the numerical model presented similar results to the experimental ones, validating the simulation. A reduction in the average temperature of the module was observed with the use of fins as a passive cooling system (an average temperature reduction of 8 °C, in the analytical study, corroborated by a reduction of 8.8 °C in the numerical simulation compared to the experimental data).","PeriodicalId":361856,"journal":{"name":"2021 9th International Renewable and Sustainable Energy Conference (IRSEC)","volume":"66 6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120874807","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper aims to design an off-grid photovoltaic (PV) solar carport to supply energy to electric cars. Sizing the off-grid solar carport system is to determine the number and type of solar panels, system voltage, batteries, charge regulator, and inverter size. In addition to sizing fuses and switches, combiner boxes, and the wires connecting the components of the system. In this case, the available parking area for which a solar carport is designed is 165 m2. Thus, 102 solar panels are installed which have an annual energy production of 42150KWh determined by the software System Advisor Model (SAM), where the performance of each solar panel annually decreases by 0.5%. For a daily energy demand of 65KWh, 40 batteries where each battery has a capacity of 220Ah, 4 inverters where each has a power rating of 25KW, and 17 charge controllers are installed. Linking the system components is done through copper wires that their length and cross-section area are sized. The economic analysis of the system concluded that the capital investment cost of the system is 661045.36MAD, the life cycle cost (LCC) is 1460022.64MAD, the levelized cost of energy (LCOE) is 1.60MAD/KWh, and the payback period is 10.5 years. The estimated amount of the mitigated CO2 emissions for the PV system is 657347Kg/year. The results of the developed system can further be used in other applications for solar PV systems sizing.","PeriodicalId":361856,"journal":{"name":"2021 9th International Renewable and Sustainable Energy Conference (IRSEC)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121558239","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The hybridization has the objective to gather the low cost of the thermal storage system of CSP with the drop in PV technology equipment. Unlike the common hybridization configuration in which CSP and PV works separately to produce electricity, through this paper we present a new configuration where the PV is used to upgrade the produced heat from CSP by using the electricity produced. Midelt city (Morocco) is selected to perform this study, and system advisor model (SAM) software to simulate the PV and CSP behavior. SAM enables for the greatest performance of CSP and PV plants by optimizing the DNI design point and tilting angle. The outcomes demonstrate that these two parameters have an impact on annual production, LCOE, and capacity factor. The best DNI design point for CSP in Midelt City is 400W/m2, while the optimum tilt angle for PV plants is 32°. Furthermore, using a PV plant to upgrade the heat transfer fluid will save the plant 163, 500 € in the first year.","PeriodicalId":361856,"journal":{"name":"2021 9th International Renewable and Sustainable Energy Conference (IRSEC)","volume":"2016 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121775156","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
