Abstract
Slush hydrogen is a two-phase solid liquid cryogenic fluid consisting of solid hydrogen particles in liquid hydrogen, various applications for which are anticipated, including the fuel for reusable space shuttles, the coolant for cold neutron generation and for superconducting equipments, as well as the transport and storage of hydrogen as a clean energy source. This paper reports on the results of three slush hydrogen production methods obtained from the laboratory scale experiments, which are the spray method, the freeze-thaw method and the auger method. Since the auger method is expected for large quantity slush hydrogen production, which is a matter of significant concern for its utilization in the future, the results of its performance analysis are reported.
