What Happened
Hyundai Engineering & Construction (Hyundai E&C) has been selected for a national R&D project under the Korea Agency for Infrastructure Technology Advancement to develop large-scale liquid hydrogen storage tanks. The project focuses on lifecycle technologies for storage, transfer, and handling at receiving terminals, targeting capacities of 4,000 m³ and 50,000 m³. It will introduce a flat-bottom cylindrical design, a first in Korea, used for LNG storage.
KRW 29 billionKRW
Project duration is 45 months from April 2026 to December 2029.
- Establishment and standardization of a physical property database for metallic materials
- Development of structural and high-performance thermal insulation design technologies
- Acquisition of structural, flow, and heat transfer analysis technologies
- Establishment of design standards, including a 200 m³ class demonstration tank to reduce boil off gas and improve safety
“While domestic and global hydrogen markets have been growing rapidly in recent years, liquid hydrogen technology, one of the core technologies essential for accelerating the transition to a hydrogen economy, is still in its infant stage.”
Why this matters
Hydrogen is a clean energy carrier, but storing it efficiently as a liquid at -253°C requires advanced technology. This project aims to create large-scale storage solutions essential for a hydrogen economy.
Terms in This Story
- Liquid hydrogen
- Hydrogen cooled to -253°C to become a liquid, allowing more efficient storage and transport.
- Boil off gas
- Gas that evaporates from a liquid due to heat ingress, which must be minimized for efficiency and safety.
