Spatial variability of green hydrogen in Türkiye: Environmental and economic perspectives

This study evaluates the environmental and economic viability of green hydrogen production in Türkiye using a high-resolution spatial model across 120 grid cells, powered by solar PV and wind energy for a 10 MW Proton Exchange Membrane electrolyzer. Unlike prior assessments that assume uniform renewable energy availability, this study integrates Global Climate Models to capture regional and climate-specific variations under three future climate scenarios. Results reveal substantial geographic differences: coastal regions such as the Aegean and Black Sea offer lower emissions and production costs due to more favourable renewable energy conditions, while central and northern areas face higher challenges. The analysis also shows that targeted policy instruments, including Production and Investment Tax Credits, can significantly improve the economic feasibility of green hydrogen. By emphasizing climate-informed, region-specific planning, this study provides a strategic framework for optimizing hydrogen production and supports Türkiye's potential role in the global clean energy transition.
