Isolation of the hydrogen and oxygen plants from the rest of the liquefaction complex, combined with appropriate transfer costs for all utilities and raw materials has been used to estimate the value of hydrogen. For the five alternatives, minimum cost hydrogen is produced by gasification of coal at 1000 psia. 500 psia gasification of coal yielded slightly more expensive hydrogen; however, on an equivalent mole basis of hydrogen, they were virtually the same. As would be expected, the cost of coal, discount cash flow rate and method of costing supplemental fuel needs were the primary variables affecting the cost of hydrogen. Hydrogen cost ranged from $0·847/1000 standard cubic feet to $2·986/1000 standard cubic feet.
