Liquid hydrogen - a potential future energy carrier

Abstract : Storage of energy is a major issue for the transformation from
a hydrocarbon based to a more ecological energy system. Liquid hydrogen has
a high potential for storage and distribution of energy because of its high density
compared to gaseous hydrogen. The presentation will start with a short overview
of the interesting physical characteristics of hydrogen. The basic thermodynamic
principles and the efficiency of cryogenic processes for refrigeration and liquefaction
of hydrogen will be introduced. Different hydrogen liquefaction processes realized
in the past and will be described together with their main design drivers.
Studies to improve the process efficiency for future high capacity hydrogen liquefaction
plants will be outlined.
