The liquefier was designed to liquefy at 1 L/hr at 3 bar with a single stage Gifford-McMahon cryocooler. The liquefier can hold up to 200 L of LH2 in a multi-layer insulated (MLI) vacuum jacketed storage tank. The liquefier includes two ortho-para hydrogen (O-P) converters, a liquid nitrogen precooler and a heat pipe. After liquefaction, LH2 can be transferred to a 5 L storage vessel using a flexible, MLI and vacuum insulated low loss transfer line. This storage vessel was designed to limit boil-off by using two 1 m long G10-CR necks to reduce conduction, a radiation shield and MLI with high vacuum to reduce radiation and convective heat leak from the outer shell to the inner tank. Presented in this paper are more detailed system configurations and results of various operational modes and applications. Copyright (C) 2015, Hydrogen Energy Publications, LLC.
