📄 Abstract（原文）
This paper investigates the techno-economic and environmental performance of a renewable-based hybrid microgrid tailored for Dublar Char, an off-grid island in the Bagerhat District of Bangladesh. The proposed system combines solar photovoltaic (PV), wind turbines (WT), fuel cells (FC), electrolyzers, hydrogen storage, and battery energy storage (BESS) to ensure reliable and sustainable electricity access in remote areas. The optimization and performance assessment were carried out using HOMER Pro (v3.14.2) with the objective of reducing both system costs and environmental impacts. The optimized configuration yields a cost of energy (COE) of $0.108/kWh and a net present cost (NPC) of $135,907, supported by an initial investment of $83,554 and minimal annual operating expenses of $184.79. A notable outcome is the achievement of a negative carbon footprint, with net CO2 emissions of –31.7 kg/year, highlighting the benefits of green hydrogen integration. Furthermore, the levelized cost of hydrogen (LCOH) is determined as $8.75/kg. These results underscore the potential of renewable–hydrogen hybrid systems as a viable pathway for rural electrification and carbon mitigation in developing region.
