A hybrid process for hydrogen production by direct solar thermolysis and electrolysis of water is described and rated thermodynamically and economically utilizing appropriate models. The results of a feasibility analysis performed for an industrial size plant module of 324 GJ/year capacity (172 GJ/year thermolysis and 152 GJ/year electrolysis) are presented. Utilizing current technology and economic assumptions applicable for power utilities, over 13% module efficiency and $39 per GJ hydrogen cost are estimated. © 1989.
