South Korea Green Hydrogen Market to Reach USD 968 Million by 2032, Growing at a CAGR of 52.9% During 2026–2032

The South Korea green hydrogen market was valued at USD 50.5 million in 2025 and is projected to increase to USD 76.4 million in 2026, reaching USD 968 million by 2032. The industry is anticipated to achieve a CAGR of approximately 52.9% during the forecast period of 2026–2032. This rapid expansion reflects the nation's accelerated transition toward a renewable energy paradigm alongside expanding industrial decarbonization initiatives across heavy manufacturing sectors.

Additionally, robust national policy frameworks and regulatory mechanisms, including the Hydrogen Economy Promotion and Hydrogen Safety Management Act, are fortifying commercial confidence. Massive public funding allocations and long-term clean hydrogen power purchase agreements are further incentivizing utility-scale project development. Consequently, industrial conglomerates and state-owned entities are ramping up long-term investments in hydrogen production, storage, and cross-border supply chain infrastructure.

Moreover, the industry is rapidly integrating digital artificial intelligence diagnostics into high-efficiency solid oxide electrolysis systems to optimize operational durability and lower overall hydrogen production costs. In parallel, strategic transport infrastructure developments, including a comprehensive nationwide hydrogen refueling station network and dedicated fleet subsidies, are continuously accelerating commercial clean hydrogen adoption across heavy mobility corridors.

Consequently, despite structural capital cost barriers surrounding advanced electrolyzers, equipment suppliers and energy project developers are capturing substantial market opportunities by engineering integrated clean hydrogen value chains. As a result, the national energy ecosystem is steadily transitioning toward widespread industrial decarbonization and long-term supply security, further states the research report, “South Korea Green Hydrogen Market Analysis, 2026.”

South Korea Green Hydrogen Market Highlights

The South Korea green hydrogen market was valued at USD 50.5 million in 2025 and is projected to reach USD 968 million by 2032. This upward trajectory is primarily driven by South Korea's accelerated transition toward a hydrogen-based energy system, industrial decarbonization initiatives, and expanding renewable-powered electrolysis projects.
The market is anticipated to expand at a CAGR of approximately 52.9% during the forecast period of 2026–2032. This sustained momentum is underpinned by public commitments, such as USD 43 billion earmarked for renewable energy development, long-term power purchase auctions awarding 6,500 GWh under 15-year contracts, and the Clean Hydrogen Certification Scheme establishing strict lifecycle emissions standards.
By technology, the Alkaline Electrolysis segment maintains a dominant market share of approximately 48.6% in 2026. Its leading position is secured by its proven commercial maturity, lower capital costs, and operational suitability for utility-scale hydrogen production projects.
Under the end-use category, the Refining & Petrochemicals segment captures a leading share of 34.9% in 2026. This popularity is significantly driven by South Korea's substantial refining capacity—averaging 2.6 million barrels per day—which requires continuous hydrogen volumes for hydroprocessing and desulfurization.
The market remains moderately consolidated, with the top five companies collectively accounting for approximately 63.0% of the market share in 2026. In this competitive landscape, leading conglomerates are prioritizing integrated hydrogen strategies, advanced ironmaking technology deployments, and cross-border clean hydrogen trade partnerships.
