摘要

Due to geographical and infrastructure limitations, the rural parts in many countries have difficulty obtaining sustainable and dependable energy. The goal of this research is to develop and improve an integrated hybrid renewable energy system (HRES) that can generate heat, hydrogen, and electricity all at once for off-grid uses. Fuel cells, diesel generators, electrolyzers, solar panels, and reformers are all combined to create a unique system. The HOMER software platform is used to improve the system configuration in order to reduce the overall net present cost while maintaining a dependable energy supply. An 80 kW fuel cell, a 100 kg/hr reformer, a 100 kW diesel generator, a 3,500 kW electrolyzer, and 6.9 MWp of PV panels make up the optimized HRES. With a levelized hydrogen cost of 4.2 €/kg, the system produces around 307,832 kg of hydrogen, 257.86 MWh of heat, and 13.45 GWh of electricity yearly. A workable approach to distant electrification is the combination of hydrogen production and storage with renewable energy. By reducing dependency on fossil fuels, this strategy not only improves energy security but also lessens environmental effects.
