This study evaluates green hydrogen production using offshore wind, solar PV, and hybrid systems at Karabiga, Türkiye. It provides 2025 and 2050 hydrogen output and levelized cost of hydrogen (LCOH) estimates, showing that CAPEX and discount rates are key drivers. It also finds that YEKA policy tools (CfD, green bonds) can effectively reduce hydrogen costs.

📄 Abstract（原文）
Abstract This study introduces a comprehensive model for green hydrogen production using Renewable Energy Sources (RESs), specifically offshore wind power (OWP) and solar energy. The framework evaluates three configurations: OWP, solar photovoltaic (PV), and a hybrid OWP–PV system—to assess their technical performance and cost effectiveness for hydrogen production using RO-treated (desalinated) seawater. For 2025, the estimated hydrogen outputs are 82.01 kg/h for the offshore-wind system, 17.87 kg/h for the PV scenario, and 99.87 kg/h for the hybrid configuration. Anticipated technological advances and cost reductions raise these values in 2050 to 130.62 kg/h, 28.46 kg/h, and 159.08 kg/h, respectively. At an 8% discount rate, the levelized cost of hydrogen (LCOH) in 2025 is 10.25 USD kg−1 for OWP, 5.97 USD kg−1 for PV, and 9.65 USD kg−1 for the hybrid system, while projected 2050 costs decline to 4.46 USD kg−1, 1.66 USD kg−1, and 3.98 USD kg−1. Sensitivity analysis shows that CAPEX, electrolyzer performance, and hydrogen output mainly drive LCOH. In Türkiye, where offshore wind installations have yet to be deployed and studies on offshore-wind-based hydrogen production remain scarce, these scenario-driven results offer timely, site-specific insights that can inform long-term energy planning and investment strategies. HIGHLIGHTS Assesses green hydrogen production from offshore wind, PV, and hybrid systems at Karabiga, Türkiye. Hybrid OWP + PV configuration achieves ≈1,394 t H2 yr−1 by 2050, ensuring continuous supply. PV-only system offers the lowest 2050 LCOH (≈1.45–1.88 USD kg−1 at r = 6–10%). LCOH is most sensitive to CAPEX and discount rate variations. YEKA policy tools (CfD, green bonds) effectively reduce hydrogen costs in Türkiye.
