The integration of photovoltaic (PV) generators with a proper storage system based on electrolytic hydrogen production is considered as a promising way to overcome the intermittence of PV power generation. Starting from a previous analysis, aimed at sizing such a PV-hydrogen stand-alone power station, a careful evaluation of the electric energy cost is performed, displaying the contribution of various components. A possible extrapolation of the present technology status is given and the prospective results are discussed. For the analyzed configuration, an energy cost of 0.22 $/kWh has been achieved in a typical energy balance situation for a small Mediterranean island. The weights of various components in the determination of this figure are examined and, finally, the possible market penetration of PV-hydrogen plants is briefly discussed, focusing on the environmental merits of the systems under investigation. © 1993.
