Hydrogen is the most promising energy carrier in near future. Liquid hydrogen has advantages in storage and transportation due to its higher density than gaseous hydrogen. Gaseous hydrogen at atmospheric condition is liquefied through cryogenic liquefaction process. This paper describes design of such cryogenic liquefaction cycles. We designed hydrogen liquefaction cycle on the basis of Linde-Hampson liquefaction system. We selected several different cycles as use of GM cryocooler and pre-cooler with liquid nitrogen. From results of analysis, principal parameters such as yield of liquid hydrogen, liquefaction rate and energy consumption are deeply discussed.
