The transition to a hydrogen-based energy system requires site-specific planning to ensure cost-effectiveness and sustainability. This study proposes an integrated framework combining Simple Weight Calculation (SIWEC) and Stable Preference Ordering Towards Ideal Solution (SPOTIS) within an interval-valued T-spherical fuzzy environment to identify optimal sites for wind-powered hydrogen production in Bangladesh. Ten years of ERA5 wind data at 100 m hub height were analyzed alongside techno-economic, climatic, geographical, socio-economic, and risk indicators derived from secondary sources and expert judgment. Results show moderate wind resources (3–5 m/s), with Noakhali, Thakurgaon, and Feni identified as the most suitable locations. The H165-4.0 MW turbine outperformed larger alternatives, yielding 58–68% higher energy output under local conditions. Sensitivity analysis reveals rectifier efficiency and discount rate as key drivers of levelized cost of hydrogen, while scenario analysis indicates a 47% cost reduction at top sites, highlighting policy and technology dependence.
