Dag Pike looks at a new tanker concept design from Japan. It was developed in response to an expected demand for transportation of liquid hydrogen.

This developed plans for what would be the world’s first ship designed to transport liquid hydrogen. This development comes in anticipation of a developing market for liquid hydrogen. It’s resulting mainly from the adoption of fuel cells in land transportation. Fuel cells can operate using several different gases but hydrogen is one of the most effective gases for this purpose.Much of the focus in the development of liquefied hydrogen (LH2) has been on the containment system that will be used to carry the liquid gas. Additionally, Kawasaki has used its extensive experience with the design and construction of liquefied natural gas (LNG) carrier ships as the basis for developing the liquid hydrogen containment system. Liquid hydrogen is a more volatile that LNG and so a modified containment system is required. Now Kawasaki has been granted approval by Class NK for the design and also fabrication of a containment system suitable for installation on the liquefied hydrogen carrier.This classification approval is based on complying with the IGC Code and ship classification rules as well as being based on the risk evaluation results from the hazard identification safety analysis (HAZID).

The containment tanks developed for liquid hydrogen are accumulation type cargo containment vessels with a capacity of 1,250m³. Liquid hydrogen has to be transported at a very low temperature – below -252°C – so the containment vessel will be cylindrical in shape and carried horizontally. Also, it will be installed entirely free from the ship’s structure…..
