Abstract

This study evaluates the technical and economic feasibility of a hybrid renewable energy system integrating photovoltaic (PV), wind turbine (WT), and green hydrogen storage for Karimunjawa Island, Indonesia. The intermittency of solar and wind energy presents challenges in maintaining grid stability, which are addressed by incorporating a hydrogen storage system. Green hydrogen is produced via electrolysis using excess renewable energy and stored for later conversion to electricity, enhancing system flexibility and reliability. Simulation and optimization used HOMER Pro to assess various system configurations based on key performance indicators, including Net Present Cost (NPC), Levelized Cost of Energy (LCOE), and Levelized Cost of Hydrogen (LCOH). The optimal configuration, comprising PV-WT-Grid-Converter- Electrolyzer, achieved an LCOE of $0.281/kWh, an LCOH of $7.546/kg, and an NPC of $ 4.74 M. Furthermore, the proposed system reduced CO₂ emissions by up to 63%, demonstrating significant environmental benefits. Comparison with diesel grids shows the proposed hybrid system produces significantly lower CO₂ emissions, demonstrating improved efficiency and environmental sustainability. The findings provide a strategic roadmap for implementing similar hybrid renewable energy systems in remote areas, ensuring sustainable and reliable energy access. © (2025), (International Information and Engineering Technology Association).
