Green hydrogen is increasingly recognized as a pivotal solution in decarbonizing hard-to-abate sectors such as steelmaking, heavy-duty transport, and chemical manufacturing. India’s abundant renewable energy potential, coupled with low-cost inputs, offers a compelling case for its emergence as a global green hydrogen hub. This study evaluates the techno-economic feasibility of site-specific green hydrogen production in India by integrating solar, wind, and hybrid renewable energy systems with PEM electrolyser technology. Through simulation modelling and updated cost parameters reflective of 2025 conditions—including CAPEX, OPEX, inflation effects, and water sourcing dynamics—this research quantifies the Levelized Cost of Hydrogen (LCH2) across 17 geographically diverse Indian locations. Key performance indicators include electrolyser utilization factor, annual hydrogen output, return on investment (ROI), and project payback period. The study finds that wind-based systems consistently deliver the lowest LCH2, with top-performing sites such as Tuticorin, Bellary, and Bedi Port achieving costs under $9/kg. Hybrid systems yield enhanced output stability with moderate LCH2 values, while standalone solar setups—although more variable in performance—offer competitive results in high irradiance zones like Leh. Sensitivity analysis reveals economies of scale, hybrid integration, and optimal oversizing strategies as the most influential cost levers. The findings provide a practical roadmap for policymakers and investors to prioritize locations, optimize renewable integration strategies, and design financial mechanisms for scaling green hydrogen in India.
