1. Hydrogen Production: Establishing a 5 Million Ton System by 2050
1.1 Grey, Blue, and Green Hydrogen Production Strategy• Status and Expansion of By-product HydrogenPOSCO currently produces 7,000 tons of by-product hydrogen annually from the steelmaking process and plans to expand this to 70,000 tons by 2025. Hyundai Oilbank possesses a maximum annual production capacity of 300,000 tons of petrochemical by-product hydrogen, currently producing 220,000 tons. The SK E&S Incheon Liquid Hydrogen Plant has established a model to refine by-product hydrogen from SK Incheon Petrochem to produce 30,000 tons of liquid hydrogen annually.
• Full-scale Blue Hydrogen ProjectsSK E&S is constructing a blue hydrogen production plant near the Boryeong LNG Terminal with a target of 250,000 tons annually. By combining natural gas reforming with CCS (Carbon Capture and Storage) technology, it aims to build a large-scale blue hydrogen supply system by 2030. POSCO plans to complete a 500,000-ton blue hydrogen production system by 2030 in cooperation with global companies.
• Long-term Green Hydrogen StrategyPOSCO aims for a hydrogen production system of 2 million tons by 2040 and 5 million tons by 2050, promoting renewable energy-based green hydrogen projects. It participated in the Oman project in 2023 and signed an MOU with Orsted of Denmark for offshore wind-linked green hydrogen production. Lotte Group is pursuing the H2biscus Project (150,000 tons of green hydrogen, 850,000 tons of green ammonia annually) based on hydropower in Sarawak, Malaysia.
1.2 Water Electrolysis Technology Development StatusHyundai Motor Group is developing megawatt-class PEM water electrolysis devices and promoting price competitiveness through fuel cell component commonization. Hanwha Solutions is researching ways to lower power consumption and initial investment compared to existing methods by developing Anion Exchange Membrane Water Electrolysis (AEMWE) technology. The government has been fully supporting the construction of water electrolysis hydrogen production bases and blue hydrogen production bases since 2024.
Currently, the SMR (Steam Methane Reforming) method is the cheapest in terms of production cost per kg, but water electrolysis green hydrogen is expected to secure economic feasibility after 2040 due to the drop in renewable energy generation costs. The government has set a hydrogen price target of KRW 3,000 per kg by 2040.
