South Korea Announces $40 Billion Green Hydrogen Strategy Targeting 2030 Industrial Deployment Across Steel, Shipping and Petrochemicals

The South Korean Ministry of Trade, Industry and Energy on Monday published a comprehensive Green Hydrogen Industrial Strategy targeting cumulative investment of approximately ₩52 trillion ($40.6 billion USD) through 2030, with explicit deployment timelines for hydrogen-based decarbonization in three priority industrial sectors: integrated steel production, deep-sea shipping fuel, and petrochemical feedstock substitution. The strategy is the most concrete Asian green hydrogen policy framework to date, exceeding the scale of comparable announcements from Japan, China, and India.

Under the framework, South Korea targets domestic green hydrogen production capacity of approximately 1.8 million tonnes per year by 2030, supplied by a mix of domestic offshore wind-coupled electrolysis (about 35% of supply), nuclear-coupled electrolysis using newly designated SMR sites (about 25%), and imported green ammonia primarily from Australia, Saudi Arabia, and Oman (the remaining 40%). The split represents a significant increase in domestic production share compared with the 2022 strategy that anticipated only 18% of supply being domestic by 2030.

The three priority sectors

POSCO Holdings has committed ₩9.8 trillion to convert its Pohang and Gwangyang integrated steel mills to hydrogen-based direct reduction iron production through 2030, with the first commercial-scale HyREX furnace targeted for operational start-up in late 2027. The strategy provides ₩3.4 trillion in matching state support for the conversion, primarily through investment tax credits and operating cost differential subsidies bridging the cost gap between green hydrogen-based steel and current blast furnace methods. Combined Korean steel sector emissions are targeted to fall 32% by 2030, with full decarbonization achievable by 2045 if deployment scales as planned.

HD Hyundai and SK Group are leading the deep-sea shipping fuel pivot, with a combined ₩7.2 trillion committed to ammonia-fuelled vessel orders, ammonia bunkering infrastructure at Busan and Ulsan ports, and renewable hydrogen-to-ammonia conversion facilities at Yeosu and Daesan. The first Korean-flagged ammonia-bunkering vessel is scheduled for delivery in mid-2027, with commercial operation targeting cargo routes between Korea, Singapore, and the Middle East. Korea aims to capture approximately 20% of the projected 2030 global ammonia bunkering market through this infrastructure-first approach.

The petrochemical sector shift, led by LG Chem and Lotte Chemical, focuses on substituting natural gas-based hydrogen feedstock for ammonia and methanol production with green hydrogen produced from offshore wind. The total commitment from petrochemical sector firms is ₩6.3 trillion through 2030, with the first commercial green hydrogen integration expected at LG Chem's Daesan facility in 2028.

Production capacity and renewable electricity scaling

Achieving the 1.8 million tonne domestic production target requires approximately 19 GW of dedicated electrolysis capacity by 2030, almost none of which currently exists in Korea. The strategy commits to specific offshore wind capacity allocations for hydrogen production: 8.5 GW of offshore wind dedicated to green hydrogen by 2030 in coastal regions of Jeollanam-do and Gyeongsangnam-do, with subsidised seabed lease arrangements aimed at lowering the levelised cost of green hydrogen below the strategy's $4.50/kg target.

The nuclear-coupled electrolysis component depends on the deployment of small modular reactors (SMRs) at three approved sites: Gori, Wolseong, and Hanul. Construction of the first 350 MW SMR cluster at Gori is scheduled for 2026-2030, with operational start-up in 2031 — meaning the nuclear-coupled green hydrogen contribution to the 2030 production target will likely fall short and be backfilled with additional offshore wind or imports.

Import partnerships and the ammonia question

Korea's strategy formalises long-term green ammonia import partnerships with Australia (initially through projects in Western Australia and the Northern Territory), Saudi Arabia (NEOM-related developments), and Oman (planned Duqm green hydrogen hub). The strategy explicitly notes that imported ammonia in 2030 will likely include some "blue ammonia" produced from natural gas with carbon capture, rather than pure renewable-source green ammonia. Critics within the Korean climate policy community argue this dilutes the strategy's decarbonization credentials, but the Ministry justified the inclusion citing supply availability constraints in the early 2030s.

According to the strategy document, total Korean green hydrogen demand by 2030 is projected at 2.9 million tonnes per year, of which 1.8 million is domestic supply and 1.1 million is imports. Of the imported component, approximately 60% is anticipated to be true green ammonia (renewable-sourced), with the balance being blue ammonia transitioning to green over the 2030-2035 period as overseas renewable-source supply scales.

Regional and competitive context

The Korean strategy is competitive with, and in some sectors more aggressive than, the Japanese hydrogen strategy revised in 2024 (targeting 3 million tonnes total demand by 2030, of which approximately 50% imports). It significantly exceeds the Indian Green Hydrogen Mission timeline (which targets 5 million tonnes annual production by 2030 but with most output dedicated to ammonia exports rather than domestic industrial decarbonization). China's 2024 Green Hydrogen Roadmap targets 5-10 million tonnes annual production by 2030, but with less specificity on industrial deployment commitments.

For Asia-Pacific climate policy observers, the Korean strategy represents the first major regional commitment with concrete project-level deployment milestones rather than aspirational capacity targets. Whether the timelines are achieved will depend significantly on offshore wind permitting reform — which the Ministry of Environment is currently undertaking — and on the cost trajectory of electrolyser manufacturing, where Korean firms Doosan and Hyundai Heavy Industries are scaling production rapidly through 2026-2027.
