Abstract
Utilization of photovoltaic (PV) generated electricity in power systems detached from the public grid usually requires both short term storage for the compensation of day/night cycles as well as long term storage for smoothing the seasonal energy harvest distinctions. Prototype systems relying on an accumulator for short term and a hydrogen path - consisting of electrolyzer, hydrogen tank and hydrogen gas engine based generator (or alternatively a fuel cell) - as long term storage have proven well in various prototype plants. A disadvantage is the electricity based generation of hydrogen for the long term storage path; rather, direct solar hydrogen production using innovative photo-electrochemical (PEC) cells - which are newly available - eases and simplifies both plant design and operation. In the following these photo-electrochemical cells are briefly characterized and their potential exemplary application for the autonomous electricity supply of an industrial plant in several configuration variants is investigated.
