*4.3. Liquid Hydrogen Production Cost*

An LH2 production cost is assumed for comparison with the LCC of the BOH reliquefaction system. The Fuel Cells Program Records from the Department of Energy provides the costs for hydrogen production and liquefaction. These documents also provide the terminal cost of LH2 [39,40]. As a result, the total cost for LH2 production and shipping is assumed to be 6.5 \$/kg as described in Table 9.
