Hyundai E&C Selected to Lead Korean Liquid Hydrogen Storage Tank Development Project

Hyundai Engineering & Construction has been selected to lead a state-backed project to develop liquid hydrogen storage infrastructure in South Korea. The project, promoted by the Korea Agency for Infrastructure Technology Advancement (KAIA) under the Ministry of Land, Infrastructure and Transport, aims to establish core technologies for liquid hydrogen receiving terminals as the hydrogen economy expands.

The initiative focuses on developing a flat-bottom liquid hydrogen storage tank—a cylindrical structure with a flat bottom designed for enhanced insulation and structural safety at atmospheric or low pressure. The project targets eventual development of 50,000 ㎥-class large-capacity storage systems.

The 45-month project runs through December 2029 with approximately 29 billion won in government funding. Hyundai E&C will collaborate with 14 industry, academic, and research partners, including Korea Gas Corporation (KOGAS), Korea Gas Technology Corporation (KOGAS-Tech), and Korea Gas Safety Corporation (KGS).

Key project deliverables include:

• Building metal material property databases and design standards
• Developing structural and high-performance insulation technologies
• Securing structural, flow, and heat transfer analysis capabilities
• Constructing and demonstrating a 200 ㎥-class prototype storage tank
• Reducing boil-off gas emissions and advancing safety protocols

The Ministry plans to apply project outcomes to large-scale terminal designs and commercial storage facility development, addressing current technological dependence on overseas sources.
