Green hydrogen is emerging as a crucial component in the global energy transition, with Türkiye's varied geography and climatic conditions providing a unique context for its production. However, existing Life Cycle Assessment (LCA) and Life Cycle Cost Assessment (LCCA) studies on hydrogen production often overlook regional variations by assuming static renewable energy capacity factors across different locations. This study addresses this limitation by evaluating the environmental and economic aspects of green hydrogen production across 120 distinct grid cells (1° x 1° resolution) in Türkiye, using PV and wind energy to power a 10 MW PEM electrolyzer system. To enhance spatial and climate-specific accuracy, Global Climate Models (GCMs) are integrated to simulate the impact of three climate scenarios (SSP5-8.5, SSP3-7.0, SSP2-4.5) on renewable energy output and hydrogen production viability. The findings reveal significant regional variations in environmental impact and production costs, with coastal areas like the Aegean and Black Sea regions showing lower emissions and costs due to favourable renewable energy conditions. Conversely, central and northern areas face higher production challenges and costs, underscoring the need for region-specific strategies. Policy analysis highlights that incentives like Production Tax Credits (PTC) and Investment Tax Credits (ITC) greatly enhance the economic feasibility of hydrogen production, recommending a tailored mix of policies to attract investment. This study’s high-resolution, climate-informed model underscores Türkiye's potential as a leader in renewable hydrogen, providing a strategic framework for optimizing hydrogen production aligned with global low-carbon goals.
