# South Korea Green Hydrogen and Ammonia Market --- ## Market Overview # CHAPTER 1 - 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. Policy support is increasingly integrated with electricity-system restructuring. South Korea's 11th Basic Plan targets average renewable additions of approximately **7 GW annually through 2030** and identifies hydrogen and ammonia among carbon-free conversion options for 12 coal units approaching retirement by 2038. Commercial demand will therefore depend on coordinated auctions, renewable-power procurement, transmission investment, fuel certification and conversion of existing thermal assets. International supply chains are strategically important because South Korea imports approximately **98% of its fossil-fuel consumption** and has limited domestic renewable-resource availability relative to prospective industrial demand. A 2026 green-ammonia agreement exceeding USD 3 billion and the first claimed commercial green-ammonia vessel bunkering in Ulsan indicate that imports, shipping, storage, certification and direct ammonia use will become central market components. ## KPIs at a Glance * Market Value: USD 1.60 billion (2025) * Dominant Region: Ulsan-Pohang Industrial Corridor (2025) * Dominant Segment: Application, led by Power Generation (2025) * Estimated Active Companies and Specialized Institutions: 420 ## Future Outlook The South Korea Green Hydrogen and Ammonia Market is projected to increase from USD 1.60 billion in 2025 to USD 4.73 billion by 2031, representing a forecast CAGR of 19.80%. Growth will be driven by clean-power procurement, commercial ammonia co-firing, electrolyzer deployment, hydrogen-ready turbines, port conversion, industrial fuel switching and imported green-ammonia contracts. Market expansion is expected to accelerate after 2027 as the first contracted power volumes begin delivery, large engineering packages reach execution and domestic technology providers commercialize standardized electrolysis, storage, cracking, turbine and bunkering systems. Project and equipment revenue will remain the largest value pool through 2028, after which molecule sales, storage, handling and long-term operating services will increase their contribution. Installed and under-construction renewable-electrolyzer capacity is projected to reach approximately 880 MW by 2031, while awarded or contracted clean hydrogen and ammonia power offtake could reach 11,000 GWh. The forecast assumes stable certification rules, continued renewable additions, improved auction design, access to internationally recognized guarantees of origin and sufficient port, terminal and transmission investment to connect imported supply with power, steel, chemical and maritime demand. --- | | | | --- | --- | | **19.80%** Forecast CAGR | **USD 4,731 Mn** 2031 Projection | --- | | | | | | --- | --- | --- | --- | | Base Year **2025** | Historical Period **2020-2025** | Forecast Period **2026-2031** | Historical CAGR **22.08%** | --- ## Scope of the Report # CHAPTER 2 -

Hydrogen and Ammonia Market in 2025? **A:** The South Korea Green Hydrogen and Ammonia Market is valued at USD 1.60 billion in 2025. The estimate includes domestic revenue attributable to renewable-electrolysis equipment, green-molecule supply, project development, engineering, conversion, storage, logistics, certification and end-use systems. It excludes gray hydrogen, conventional fossil-based ammonia, unrelated fuel-cell electricity revenue, internal transfer pricing and overseas project revenue not attributable to Korean market demand. The estimate is triangulated from company activity, project capacity, procurement, equipment expenditure and end-user investment. **Data used:** USD 1.60 billion market value in 2025; confidence range of USD 1.46-1.74 billion. **So what:** Investors should evaluate the market as an integrated infrastructure and molecule ecosystem rather than a standalone hydrogen-commodity market. #### Q: What growth rate is forecast for the market? **A:** The market is projected to grow at a CAGR of 19.80% during 2026-2031, reaching USD 4.73 billion by 2031. Expansion will be supported by clean-power procurement, ammonia co-firing, electrolyzer packages, port infrastructure, hydrogen-ready generation, industrial decarbonization and maritime applications. Revenue growth is expected to become more balanced over time as molecule sales, terminal throughput, certification, maintenance and operating services increase alongside project and equipment expenditure. **Data used:** 19.80% forecast CAGR; USD 4.73 billion projected market value in 2031. **So what:** Market entrants should secure positions before commercial fuel delivery accelerates after 2027. #### Q: Which application is the largest market segment? **A:** Power Generation is the largest application, accounting for an estimated 38% of market revenue in 2025. Its leading position reflects the dedicated clean-hydrogen power auction, large potential fuel volumes and the ability to convert existing thermal-generation infrastructure. The first awarded project plans 20% ammonia co-firing and approximately 750 GWh of annual generation from 2028. Steel, chemicals and shipping are smaller current segments but provide strong long-term diversification and potentially higher emissions-abatement value. **Data used:** Power Generation share of 38%; 750 GWh annual awarded generation. **So what:** Suppliers should use utility demand as an anchor while developing direct industrial and maritime applications. #### Q: Why is green ammonia strategically important in South Korea? **A:** Green ammonia is important because it can be transported using established marine logistics, stored at ports, used directly in power generation and shipping, or cracked into hydrogen. This flexibility addresses South Korea's limited domestic renewable-resource base and high dependence on imported energy. Its role is reinforced by a green-ammonia supply agreement exceeding USD 3 billion, the country's first clean-power award and the first claimed commercial green-ammonia vessel bunkering in Ulsan during 2026. **Data used:** More than USD 3 billion supply agreement; 15-year contract duration. **So what:** Port, terminal and direct-use ammonia assets may achieve stronger economics than projects requiring repeated hydrogen conversion. #### Q: How competitive is the market? **A:** Competition is moderately concentrated among large Korean industrial groups, state generation companies and engineering firms. The ten profiled participants account for an estimated 42.9% of addressable market revenue, while specialized manufacturers, research institutions, component suppliers and project developers serve the remaining market. Competitive advantage depends less on standalone technology and more on integrated access to fuel supply, creditworthy offtake, ports, engineering, lifecycle certification and long-term capital. **Data used:** Top 10 concentration of 42.9%; approximately 420 active companies and specialized institutions. **So what:** New entrants generally require consortium partnerships rather than independent market entry. #### Q: What are the principal risks affecting the forecast? **A:** The main risks are high delivered fuel cost, auction redesign, renewable-power constraints, terminal delays, certification incompatibility, conversion losses and competition from direct electrification. The cancellation and redesign of the planned 2025 clean-hydrogen auction illustrate procurement uncertainty. Imported molecules also expose projects to shipping, exchange-rate and geopolitical risk. The constrained forecast assumes slower auctions and delayed infrastructure, reducing the 2031 market outcome to approximately USD 3.51 billion. **Data used:** Bear-case 2031 value of USD 3.51 billion; bear-case CAGR of 14.00%. **So what:** Investors should require diversified demand, indexed contracts and staged capital deployment. #### Q: Where are the strongest investment opportunities? **A:** The strongest opportunities are certified green-ammonia import hubs, standardized electrolysis packages, hydrogen-ready power equipment, industrial hydrogen supply, ammonia bunkering and lifecycle certification platforms. Ulsan-Pohang offers the most concentrated industrial demand, while Jeju provides valuable demonstration conditions and the Honam-West Coast belt combines renewable resources, ports and thermal-generation conversion. Attractive projects combine long-term offtake, modular capacity, internationally recognized emissions data and multiple end-use customers. **Data used:** Ulsan-Pohang estimated regional share of 31%; forecast market CAGR of 19.80%. **So what:** Integrated infrastructure with multiple revenue streams is more defensible than single-customer molecule supply. --- ## Table of Contents # CHAPTER 14 - Table Of Contents ### Market Report Structure Comprehensive coverage across three strategic phases — Market Assessment, Go-To-Market Strategy, and Survey — delivering end-to-end insights from market analysis and execution roadmap to customer demand validation. ## Market Assessment Phase Supply-side and competitive intelligence covering market sizing, segmentation, competitive dynamics, regulatory landscape, and future forecasts. ### 1.
