In the present study, a test-rig was designed and constructed for conducting a set of experiments on a solar assisted desalination unit working on a HDH principle under the prevailing conditions of Tajoura-Libya. Experiments were carried out on specified days in March, 2019 at the laboratories of Center for Solar Energy Research and Studies (CSERS) at Tajoura. The effect of different design parameters and operating conditions on the performance of the unit and its productivity is closely investigated and interpreted. Results show that the productivity of the HDH unit decreases by increasing the process air mass flow rate. A significant improvement in the productivity of the unit is noticed when the feed water mass flow rate to the humidifier is increased. Furthermore, initial water temperature inside the tank has a remarked effect on the productivity of the unit. In order to obtain a reasonable amount of fresh water, the temperature of the water inside the tank should be increased. Increasing the cooling water mass flow rate to the dehumidifier leads to a corresponding decrease in the surface temperature of the cooling coil and hence the productivity of the unit is improved. The Productivity of the unit is varying from its lower value of (0.903 kg/m2.day) to a higher value of (6.47 kg/m2.day). These values are obtained for one meter square of solar air heater area. Gained Output Ratio (GOR) values range from a minimum of (0.082) to a maximum of (0.572). It is reasonable when compared to ones in literature for the water-heated HDH units.","PeriodicalId":232564,"journal":{"name":"Solar Energy and Sustainable Development journal","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125604872","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}

To replace conventional energy sources such as (oil, coal, etc.) for several reasons. mainly, because of the negative environmental impact of the Greenhouse Gas (GHG) emission problem. Also, these resources will deplete soon. As a result, seeking for a better replacement of fossil fuels either by converting to electric vehicles or by using other possible renewable energy sources with low (GHG) emissions is essential. Hydrogen is one of the primary potential future alternatives of current automotive petroleumrelated due to its high mass-energy ratio and abundance since it can be obtained from a broad spectrum of sources and by various techniques, such as anaerobic digestion from organic materials, rendering it a prospective target for safe and renewable energy. Hydrogen fuel stations are predicted to have a significant impact on the implementation of hydrogen as a fuel substitution on the worldwide fuel market, especially for heavy transportation. The primary objective of this innovative station branch is not only to promote the idea of hydrogen fuel on the vehicle fuelling industry but also to enhance the advancement of hydrogen fuel facilities while minimizing the danger to the investor. There are, though, some areas that need to be investigated with such drop-in facilities as storage and delivery mechanisms which this study covers. The key idea of such a system is to provide a safe, affordable and accessible car fuel source equivalent to conventional vehicle fuel on the industry, whether it is renewable. The primary goal of this research is to develop a secure, flexible and environmentally friendly hydrogen fueling facility, this design is regarded to be cost-efficient compared to other designs by at least 48 percent. Furthermore, this design showed encouraging signs concerning safety procedures and hazard evaluation where is ranked 6.8 on average out of 25 in the FMEA review assuring it’s safe further.","PeriodicalId":232564,"journal":{"name":"Solar Energy and Sustainable Development journal","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-02-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126920473","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 paper, a thermodynamic model is presented to design and optimize a direct coupling system (DCS) that has twocells, an alkaline electrolysis cell (AEC) and a proton exchange membrane fuel cell (PEMFC).

Th simulations result show that, the voltage of alkaline electrolysis is higher than the fuel cell. Th water management process in the whole system is considered satisfactory due tothe low value of the losses in the amount of water.
