“…Batteries are the most soughtafter among the different hydrogen storage device technologies. However, because of their energy leakage between 1% and 5% per hour, and their low energy densities, they are not useful for long-term operation of power systems [16]. Hydrogen can be a good choice due to its high energy density, low energy loss, mature technology, on-site provision capability, and compactness [17][18][19][20].…”

The rising demand for high-density power storage systems such as hydrogen, combined with renewable power production systems, has led to the design of optimal power production and storage systems. In this study, a wind and photovoltaic (PV) hybrid electrolyzer system, which maximizes the hydrogen production for a diurnal operation of the system, is designed and simulated. The operation of the system is optimized using imperialist competitive algorithm (ICA). The objective of this optimization is to combine the PV array and wind turbine (WT) in a way that, for minimized average excess power generation, maximum hydrogen would be produced. Actual meteorological data of Miami is used for simulations. A framework of the advanced alkaline electrolyzer with the detailed electrochemical model is used. This optimal system comprises a PV module with a power of 7.9 kW and a WT module with a power of 11 kW. The rate of hydrogen production is 0.0192 mol/s; an average Faraday efficiency of 86.9 percent. The electrolyzer works with 53.7 percent of its nominal power. The availability of the wind for longer periods of time reflects the greater contribution of WT in comparison with PV towards the overall throughput of the system.

Abstract. The popularity of weather sensors has encouraged the advance of campus weather station, which helps to automatically or manually measure temperature, humidity, wind speed and direction, pressure, solar radiation and soil temperatures. Technology rich classroom, as the most important smart learning environment, need the weather data from campus weather station to provide comfortable environment. Most of weather monitoring systems (WMS) are implemented with high-cost sensing devices for detecting weather data of schools or colleges. In this study, we proposed a WMS which uses Raspberry Pi and weather Sensor to support weather monitoring. This system is a low-cost portable weather data collection system which allows collecting, storing and transmitting data.

Abstract:The use of PV array energy in supplying the electrolyzer systems is very suitable. During the daylight hours, the sunlight converts by PV array into electrical energy which will be used for electrolyzing process. Then hydrogen produced by the electrolyzer is compressed and stored in hydrogen vessel. This provides energy for the fuel cell to meet the load when the solar energy is insufficient. Solar hydrogen technology is relatively simple and the only raw material for the production of solar hydrogen is water. In this study technical results obtained from direct connection of 10 kW PV array with 5 kW electrolyzer systems for hydrogen production and storage at Taleghan site. Variations of the solar radiation intensity, hydrogen production rate, solar hydrogen efficiency and overall efficiency of solar hydrogen energy were considered as base of analyses. It is found that the minimum and maximum overall energy efficiency values of the system are 0.93 % and 5.01 %, respectively. The result shows a great potential in direct solar radiation for absorbing and converting it to other types of energy in Iran. Using solar energy required high initial investment, so converting solar energy to other types of energy with high efficiency systems is vital.
