CHAPTER 1 - MARKET SUMMARY
Market Overview
The South Korea Green Hydrogen and Ammonia Market is transitioning from publicly funded demonstrations toward contracted commercial demand. The inaugural clean-hydrogen power auction awarded approximately 750 GWh of annual generation to an ammonia co-firing project scheduled to begin supply in 2028. Its 15-year revenue structure establishes an initial bankability benchmark for imported green ammonia, power utilities, port operators and fuel-certification providers.
Domestic green-hydrogen production remains demonstration-led. Jeju operates a 3.3 MW renewable-electrolysis facility capable of producing up to 600 kilograms per day through alkaline and PEM systems. Approximately 30 tonnes were supplied to mobility applications during 2024. Data from this facility supports a 12.5 MW follow-on demonstration and a planned 50 MW provincial production system by 2030.
