Research and Development of Basic Technologies for Hydrogen Energy Marine Transportation

Abstract

Synopsis: To develop basic technologies for the marine transportation of hydrogen energy, a liquid hydrogen experiment facility (LHEF) has been designed and constructed at the Fukae campus of Kobe University. This LHEF consists of an experiment room, a measurement room, a H2 gas vent line, a vacuum pumping line, high-pressure gas security equipment, etc. A liquid hydrogen (LH2) optical cryostat equipped with a vacuum jacket, a liquid nitrogen space (15 L) and LH2 space (20 L) has been installed in the experiment room. This paper explains the details of constructing the LHEF, including countermeasures for high-pressure gas security and experimental results using LH2 obtained so far.
