Abstract: In the present study a design procedure for hydrogen storage systems in power plants with renewable energy is presented. The storage system eonsists of an electrolyzer, gas storage in high pressure tanks and reconversion into electricity by a fuel cell . This work is based an the experiences male by construction and operation of the demonstration plant PHOEBUS Jülich for Photovoltaik, Elektrolyse, Brennstoffzelle und Systemtechnik (photovoltaics, electrolysis, fuel cell and System engineering) at the Research Centre Jülich. These systems are treated by dynamic simulation in a high temporal resolution. The seasonal and the stochastical behaviour of the yield of renewable energy and energy consumption is taken into account by simulating over a time span of 17 years using measured meteorologieal data. For optimization the autarky-limit-procedure is introduced. A cost model is applied to the results of the simulation . The autarky-limit describes the correlation between the capacity of the installed gas tank and the rated power of the installed converters for renewable energy in case of exactly seif-sufficient plant operation . Using the autarky-Iimit procedure, it is possible to size all major components for long-term operation at minimal costs. The procedure is applied for a modelled consumer at Research Centre Jülich site . Various configurations of the storage system are investigated and compared . More generalized statements about a reasonable use of hydrogen storage are derived from the results .
