Cox, K E

A survey of capital cost estimates and process efficiencies for two different technologies for producing hydrogen from water has been completed. Thermochemical cycles show costs ranging from $600 to 1100/kW H/sub 2/ while advanced methods of water electrolysis were estimated in the range of $700 to 1100/kW H/sub 2/. In general, efficiencies for thermochemical cycles were higher at 40 to 55%, than for water electrolysis systems at 30 to 40%. In all evaluations of new technology, careful attention must be paid to the assumptions underlying the derived cost and efficiency to ensure that design conditions conform to achievable results.
