Liquefied hydrogen needs to be stored at extremely low temperatures. The boil-off rate is the daily evaporation rate of a compressed liquid due to increases in temperature. This is an important factor for the HESC Project, which will transport liquefied hydrogen by boat from the Port of Hastings, Victoria to Japan.   The pilot project’s marine carrier, the Suiso Frontier, achieved an extremely low boil-off rate of 0.3% per day, and the onshore LH2 storage tank in Kobe, Japan has a boil-off rate of 0.06% per day.   This is a significant improvement on traditional storage technology. The innovative next generation storage tanks developed by Kawasaki Heavy Industries, can store and transport LH2 at -253 Celsius.    Technology from both the carrier and the onshore storage tank will be improved upon and used to increase the efficiency of storage and transportation during the commercial phase of the project.   A commercial-scale hydrogen carrier could even use boil-off hydrogen as fuel to drive the engines.
