The dead state temperatures considered here are 10 degrees C 20 degrees C and 30 degrees C to undertake a parametric study. An electrolyzer and a metal hydride tank are used for hydrogen production and hydrogen storage respectively. Also the Proton Exchange Membrane Fuel Cell (PEMFC) and battery options are utilized for electricity generation and storage respectively. As a result the energy and exergy efficiencies and the sustainability index for the wind turbine are found to be higher than the ones for solar photovoltaic (PV) system. Also the overall exergy efficiency of the system is found to be higher than the corresponding overall energy efficiency. Furthermore for this system it can be concluded that wind turbine with 60 gCO(2)/month is more environmentally-benign than the solar PV system with 75 gCO(2)/month. Finally the total exergoeconomic parameter is found to be 0.26 W/$ when the energy loss is considered while it is 0.41 W/$ when the total of exergy loss and destruction rates are taken into account.
