Dynamic Simulation of the Annual Performance of PV-Wind System for Hydrogen Generation in Egypt Using TRNSYS

Hydrogen generation from new and renewable energy sources such as solar and wind energy has become the focus of attention of the world countries because of the advantages enjoyed by green hydrogen, that is produced using new and renewable energy. In this research, a large-scale hydrogen generation system using a hybrid Solar-Wind power system has been studied and simulated under Cairo's climate. Two other regions in Egypt (Aswan and ElZafranah) were also chosen to conduct these studies. Each region has an abundance of one renewable energy source, Aswan has a high solar radiation capacity throughout the year, as well as the ElZafranah region. While ElZafranah region has an abundance of wind energy throughout the year. Dynamic simulation for the hybrid PV-Wind system to generate hydrogen was carried out using the TRNSYS17 software. From the simulation results, it was found that ElZafranah has the best hydrogen production from wind energy, where the annual hydrogen produced was about 760*103 m3/year, and Aswan came as the best location for hydrogen production from PV cells, as the annual hydrogen produced was 499*103 m3/year. The annual electricity production for the hybrid PV-wind turbine systems, for ElZafranah, Cairo, and Aswan were 3244, 1507.1, and 2281.6 MWh, respectively. Also, an economic analysis of hydrogen production from renewable energy sources was carried out in this study.
