Description
Hydrogen is an ultimate energy source because only water is produced after the chemical reaction of hydrogen and oxygen. In the near future, a large amount of hydrogen, produced using sustainable/renewable energy, is expected to be consumed. Since liquid hydrogen (LH2) has the advantage of high storage efficiency, it is greatly attractive as the ultimate medium for the worldwide storage and transport of large amount of hydrogen. Recently, development of LH2 tanks and carriers as well as liquefied natural gas tanks and carriers are ongoing. It is important to elucidate the sloshing condition inside an LH2 tank during transportation by truck and ship. To make a calculation model of the sloshing of LH2 inside a tank, simulation of LH2 level, temperature and pressure inside the tank during transportation were carried out using a multipurpose software ANSYS CFX. Calculated results are discussed in comparison with experimental results of a 2000 liter tank during transportation by truck.
