TECHNO-ECONOMIC EVALUATION OF WIND-HYDROGEN HYBRID SYSTEM IN IRAN
Rising levels of the greenhouse gases (GHGs) in the earths atmosphere result in global warming. The combined effect of the widespread depletion of fossil fuels and the gradually emerging consciousness about environmental degradation has given priority to the use of conventional and renewable alternative energy sources such as solar and wind energies, hydrogen or combination of them. In this study a wind-hydrogen hybrid system is considered. Wind-hydrogen hybrid systems can reduce the need for curtailment of wind farms, save wasted energy, reduce backup power, reduce transmission losses, and generate large revenue by selling power at peak times. In present work, a techno-economic evaluation of wind-hydrogen hybrid system which consists of small-scaled wind turbine, electrolysis, and PEM in household size, will be considered. A kW range small wind turbine is chosen for achieving the available annual wind energy in given five points in Iran. In order to save the output energy of wind turbine, electrolysis is used to convert this energy into hydrogen chemical energy. Generated hydrogen is stored in hydrogen storage tank. When we need extra power a PEM fuel cell is applied to convert chemical energy of hydrogen into power with high efficiency. All of simulation is done by MATLAB. Finally by using simulation data an energy and economic analysis are considered. Results shown that by using 2 kW wind turbine, 1200 gr hydrogen can be produced in the best condition.
