Renewable Energy and Hydrogen Storage System Analysis for Carbon Neutral Campuses with HOMER

This study focuses on the design and techno-economic analysis of a Hybrid Energy System (HES) aimed at reducing carbon emissions for Dicle University in Diyarbakır, Turkey. The system integrates photovoltaic panels (PV), wind turbines (WT), battery storage systems (BSS), electrolyzers, and hydrogen storage tanks (HST) to create a sustainable and efficient energy solution. Diyarbakır’s high solar radiation and wind potential make it a suitable location for such an implementation. HOMER Pro software was utilized to model and optimize the system based on local meteorological data, evaluating the technical and economic performance. The designed HRES meets a daily energy demand of 34.3 kWh and is composed of an 8 kW PV array, a 5 kW WT, an 18 kWh BSS, a 7 kW electrolyzer, and a 400 kg hydrogen storage capacity. The system has a total capital cost of $287,577, a Net Present Cost (NPC) of $588,188, and a Levelized Cost of Energy (LCOE) of $11.09/kWh. The results demonstrate the feasibility and efficiency of integrating renewable energy with hydrogen storage to achieve energy reliability, sustainability, and reduced carbon emissions.
