Next-Generation Liquid Hydrogen Shipping Tanks for Long-Distance Maritime Transport

transportTestedTRL 6

Imagine trying to move a giant thermos of liquid that is colder than anything on Earth. This project builds a special kind of 'super-flask' for ships that keeps hydrogen liquid at -253°C without letting the heat leak in. It's like upgrading a standard cooler to a high-tech freezer that can be scaled up to the size of a massive cargo ship.

The business problem

What needed solving

Transporting liquid hydrogen over long distances is difficult because it requires extreme cold (-253°C) and often suffers from high fuel loss (boil-off). Current storage solutions lack the scale and modularity needed for large-scale commercial shipping.

The solution

What was built

A modular membrane-type Cargo Containment System (CCS) and a 180 m3 physical prototype demonstrator. The project also produced a preliminary integrated ship design and a life cycle model for environmental impact.

Who can put this to work

Maritime Shipping
enterprise
Target: LNG Carrier Operators

If you are a ship owner dealing with the transition to carbon-neutral fuels — this project developed a membrane-type containment system that allows for LH2 storage up to 200,000 m3. This enables the transport of large quantities of hydrogen over long distances using a design similar to existing LNG carriers.

Shipbuilding
enterprise
Target: Commercial Vessel Shipyards

If you are a shipyard dealing with the need for modular fuel tank designs — this project developed modular building blocks for LH2 storage. This allows you to scale tanks up or down to fit various ship designs and sizes.

Energy Logistics
any
Target: Hydrogen Energy Suppliers

If you are an energy provider dealing with high fuel loss during transport — this project developed a system achieving reduced boil-off rates of 0.5% per day. This ensures more product reaches the destination, improving the commercial attractiveness of LH2 shipping.

Frequently asked

Quick answers

What is the estimated cost or price of the system?

Based on available project data, the project includes a preliminary integrated ship design and a corresponding cost estimation, but specific price figures are not provided.

Can this be scaled for different ship sizes?

Yes, the design uses modular building blocks that allow LH2 storage to be scaled to larger or smaller dimensions, similar to the variations seen in LNG carriers.

Who owns the IP or how is licensing handled?

Based on available project data, there is no specific information regarding IP ownership or licensing terms, though the project involves 14 partners across 9 countries.

Does the design meet international safety standards?

Yes, the core technologies and risk assessments are reviewed by ABS, a major IACS Classification Society, to issue an Approval-in-Principle (AiP).

How long does it take to implement this technology?

The project period runs from 2023-06-01 to 2027-05-31, indicating a four-year development and validation cycle.

Consortium

Who built it

The consortium is heavily industry-driven with a 64% industry ratio, comprising 9 industrial partners and 3 SMEs. This strong commercial presence, combined with 4 universities across 9 countries (including Korea and the UK), suggests a high focus on market viability and technical standardization rather than pure academic research.
