1- The following energy storage system is used to store the power produced from the PV system during the daytime to be used during the nighttime for a total load of 2000 kWh during 10 hours. Given that: Intercooler AC Hydrogen Tank DC-AC PV efficiency is 0.18, converter efficiency is 0.87, compressor isentropic efficiency is 0.85, average solar intensity during the day time for 8 hours is 500 W, Electrolyzer efficiency at standard pressure and temperature (1 bar and 25 °C) is 0.7, power output from the fuel cell is specified by: AC Bus Converter Fuel Cell ELECTRICAL DEMAND Pfuel cell 76.4 VH2-0.84 Where Pfuel cell is the fuel cell output power in W as DC VH2 is the volume flow rate of H₂ in liter per minutes at standard conditions. The hydrogen is stored inside the tank during the day time at 100 bar and 25 °C. Calculate: (a) The minimum volume of hydrogen tank. (b) The average fuel cell efficiency. (c) The surface area of the PV system. (d) The heat dissipated from the intercooler. (e) The water flow rate inlet to the electrloyzer. (f) The overall system efficiency.
