Abstract: Energy is a critical foundation for socio-economic development of any country. This study assesses the performance of the Solar Photovoltaic Pumping System toward an integrated rural area transformation in the village of Sekoukou in Niger (West Africa). Electrical parameters, meteorological data and the PVsyst software are used respectively for data measurement/collection and the systems performance analyses based on three different scenarios related to population growth The results of the study reveal that the output power of the PV arrays depends significantly with the sun irradiance with an average peak power of 540 W for 783 W/m2 average sun irradiance. The average performance of the motor-pump discharge observed is 35%. The study shows that the performance of the system depends significantly on the meteorological condition as well as the water demand and also the size of the storage tank. Moreover, the simulation results using PVsyst model show that the solar pumping system could afford respectively 84.7 %, 74.8%, and 62.5% of the water demand for the community according to population growth scenarios in 2025, 2030 and 2035 respectively. Additionally, the installed PV arrays is oversize compare to the pump energy requirements, therefore the system could not provide the sufficient water demand in the horizon 2035 due to the lower discharge of the motor-pump.

Abstract: Hydrogen is an important secondary renewable energy source, and its efficient use depends on the development of safe, economical, and portable hydrogen storage technology. Current hydrogen storage methods are divided into physical and chemical methods, and physical methods include three categories: low-temperature liquid storage, adsorption storage, and high-pressure gaseous storage. However, hydrogen can easily escape and undergo chemical reactions, being difficult to simultaneously meet requirements of safety, economy, and portability. A honeycomb-structured tube bundle made of glass fiber for high-pressure gaseous hydrogen storage has been proposed to overcome shortcomings of existing methods both theoretically and experimentally. To further develop this technology, various structural adjustments and improvements are introduced. Microscale cylindrical tubes made from glass fibers produced using optical fiber technology are combined in an array (bundle), and the array surface is protected by a steel sleeve. The array is completely closed at one end, and high-pressure hydrogen (100 MPa) can be rushed into the other end for storage or transportation. Unlike the existing thin-walled tube bundle and external hexagonal honeycomb structure, thick-walled tube bundles are directly used to form a honeycomb structure, and different protective sleeve materials are tested. The influence of various parameters, such as number of tubes and wall thickness, on the hydrogen storage performance of the tube bundle is evaluated using the finite element method. Comparing numerical and experimental results show that the number of tubes in a bundle is negatively related to the storage performance, and increasing the tube wall thickness increases performance up to a certain value, after which further thickening reduces performance.
