انرژی، اکسرژی و تجزیه و تحلیل اقتصادی یک انرژی تجدید پذیر ترکیبی با سیستم ذخیره سازی هیدروژنی

The goal of this study is to define and assess an off-grid hybrid renewable energy with hydrogen storage system. The system combines solar and wind energy, hydrogen production unit and fuel cell. This photovoltaic/wind hydrogen energy system focuses on a large scale system with constant electrical load and especially suitable for remote area applications. Energy, exergy and economic analysis are conducted for this system. The pattern of the produced power for the photovoltaic (PV) system and wind turbine with a dynamic model of solar and wind energy are determined. Also, components sizing of the proposed system is determined. Energy and exergy analysis of the PV system was reported the average of 12% and 16% for energy and exergy efficiencies, respectively. The average energy and exergy efficiencies of the wind turbine were obtained approximately 32% and 25%, respectively. The maximum exergy destruction for the PV system was obtained around 65%. Also, based on economic analysis, energy storage system was included 50% of the total investment.
