World largest Hydrogen Liquefaction Facility built in Korea
24. October 2024SK E&S Co., a leading South Korean liquefied natural gas importer, has completed the construction of the world’s largest hydrogen liquefaction plant in Incheon, west of Seoul. This facility, expected to play a pivotal role in South Korea’s shift to a hydrogen economy, was built between 2021 and 2023 at a cost of 700 billion won ($513 million). It comprises three production units, each capable of producing 30 tons of liquefied hydrogen per day, along with six storage facilities with a capacity of 20 tons each. Equipment and components relevant to hydrogen production and storage typically require KGS certification to be approved for import and sale in Korea.
The plant, with an annual production capacity of 30,000 tons of liquefied hydrogen, purifies by-product hydrogen from SK Incheon Petrochem Co. into high-purity hydrogen and cools it to cryogenic temperatures of minus 253 degrees Celsius for liquefaction. The facility is capable of supplying hydrogen to fuel 5,000 buses and represents a key infrastructure development in the country’s hydrogen sector. SK E&S plans to establish 20 liquefied hydrogen charging stations across Korea this year, aiming to double that number by 2026.
