Its theoretical search for an optimum closed-cycle thermochemical process for the production of hydrogen has led the University of Pennsylvania to the tentative conclusion that, as previous research has shown for 2-step cycles, a workable 3-step cycle probably does not exist. Because economics impose a severe restriction on the allowable number of reaction steps, a thermochemical process involving four or more reactions cannot successfully compete with direct electrolysis for hydrogen production. The conclusion is based on a systematic thermodynamic analysis of the simplest and most promising 3-step processes that have been proposed and several 4-step cycles that can be considered as extensions of 3-step patterns.
