During this phase of the project, Task 4.4, led by HYDRUS, examined how liquid hydrogen storage systems can be safely incorporated into different types of ships and adapted to their specific operational needs.
The work considers several practical factors, including the size of the storage system, the type of vessel, the intended route, and whether liquid hydrogen will be transported as cargo or used as a marine fuel. The aim is to develop flexible solutions that can be applied across different parts of the shipping sector rather than being limited to a single vessel design.
The project has assessed a range of ship types, including tankers, bulk carriers, container ships, RoPax vessels, and double-ended ferries. Different storage technologies have also been examined, such as Type A tanks, Type C tanks, and membrane systems, to identify suitable options for each type of application.
This work supports the development of adaptable hydrogen solutions that can respond to different vessel sizes, operating profiles, and commercial requirements while maintaining safety and efficiency. The assessment has also benefited from knowledge exchange with related research projects, including NH3CRAFT and SAFeCRAFT, helping the team consider a wider range of design approaches.
By project month 36, drawings had been completed for Cases 4A, 6, and 7. These cases involve liquid hydrogen stored in Type C tanks and used as fuel in dual-fuel, four-stroke engines for either ship propulsion or electricity generation.
