The development of hydrogen energy technologies has gained global momentum as countries seek sustainable and low-carbon alternatives to conventional fossil fuels. This paper presents a comparative analysis of hydrogen technology development in South Korea and its applicability to the emerging energy sector in Uzbekistan. South Korea’s strategic roadmap, robust investment in research and development, and active industrial participation have positioned it as a global leader in hydrogen innovation. In contrast, Uzbekistan is at a nascent stage in its hydrogen transition, with growing interest but limited infrastructure and policy frameworks. This study employs a mixed-method approach, including an extensive literature review, policy analysis, and examination of case studies, to evaluate the transferability of Korean hydrogen technologies to the Uzbek context. The findings indicate that several Korean technologies, particularly in hydrogen production via electrolysis and fuel cell systems, are technically compatible with Uzbekistan’s renewable energy potential.
