Lloyd’s Register and Pusan National University have partnered to create the first global certification framework for liquid hydrogen shipping. They signed a memorandum of understanding in Seoul.
The project will develop a joint system to evaluate and certify liquid hydrogen carriers and onboard systems. It will focus on safety, consistency, and global use.
Hydrogen is emerging as a zero-carbon fuel. However, the maritime sector lacks clear standards. Liquid hydrogen creates major technical challenges. It must be stored at around –253°C. This requires advanced materials, strong containment systems, and strict safety design.
The new framework will set clear rules for performance, safety, and reliability. It will reduce uncertainty during design, approval, and construction.
The partnership combines LR’s classification expertise with PNU’s research in cryogenic engineering. Together, they will build a structured certification system. It will cover containment systems, materials, and onboard infrastructure.
Under the agreement, the partners will:
- Test cryogenic storage and insulation performance
- Verify structural strength under operating conditions
- Conduct safety and risk assessments.
They will also define testing methods and certification procedures for marine use. The results will support future class rules and global regulations.
“As pressure mounts on shipping to decarbonise, a clear and robust certification pathway will accelerate projects and reduce barriers,” said Claudene Sharp-Patel of Lloyd’s Register. “Our partnership with PNU will help move liquid hydrogen from concept to commercial reality.”
Dr. Jae-Myung Lee of Pusan National University said: “This agreement establishes the world’s first certification body for liquid hydrogen in shipping.”
The partners build on existing research and knowledge sharing. They aim to speed up the development of liquid hydrogen vessels and support maritime decarbonization.
