What is it? Design of prism liquid hydrogen tank

A prism liquid hydrogen tank is a container designed specifically for storing liquid hydrogen, suitable for extremely low-temperature environments. Hydrogen needs to be cooled to near its boiling point (-253°C) in order to be stored and transported for long periods of time. This prism-shaped liquid hydrogen tank developed by the Norwegian company CryoVac features an innovative design that uses hexagonal vacuum insulation panels. These plates are connected by welding to form a continuous surface, creating an efficient mixed-insulation system. The advantage of this design is its ability to effectively reduce heat transfer, thereby maintaining the hydrogen in a super-low temperature state. Furthermore, the prism-shaped design helps improve the space utilization of the tank, making it more suitable for use in vehicles such as ships. DNV’s approval indicates that this design meets international safety and performance standards, representing an important innovation in the field of liquid hydrogen transportation. .

Hexagonal vacuum panels are welded together to form a continuous surface, and arranged as a hybrid insulation system that allows for the use of simple prism tanks for liquid hydrogen transport. 　　This provides ultra-low evaporation insulation without compromising the integrity of the steel in liquid hydrogen sealing systems?

It should be roughly the same; this structure, which is similar to a multi-layered combination of prisms, can effectively block external thermal radiation, thereby reducing the evaporation rate of liquid hydrogen.

Which companies are using this type of transportation nowadays?

Once the manufacturing issue is resolved, it can be used
