Green Hydrogen Production from Hybrid PV-Wind Energy in Adrar, Algeria:A HOMER Pro Techno-Economic Optimization Study

Abstract

This paper presents a techno-economic feasibility study for a green hydrogen production system based on hybrid photovoltaic-wind energy in the Adrar region of southern Algeria, using HOMER Pro software. The system integrates a 2,500 kWp PV array, four 300 kW wind turbines, a 1,800 kW PEM electrolyzer, 1,000 kg compressed hydrogen storage at 350 bar, a 500 kW PEM fuel cell, and a 1,000 kWh Li-ion battery bank. HOMER Pro optimization yields 521.4 t H2/year with 97.8% renewable fraction. LCOH = $3.84/kg (PEM) and $4.12/kg (alkaline); NPC = $18.74 M over 25 years. The system avoids 6,842 tCO2/year vs. SMR. Sensitivity analysis identifies discount rate and PV capital cost as dominant parameters. Results confirm Adrar is highly suitable for competitive green hydrogen production.
