Abstract:
The combination of the conventional technology of electric energy supply without any interruptions with the use of renewable energy for production of electricity (photovoltaic, wind power, small hydropower stations), the possibility to store electrical energy using hydrogen as an energy carrier, and the direct conversion of the chemical energy into electricity by low temperature fuel cells opens a way for the supply of insularities in small and large scale as well. The advantages of such systems, mainly complete automation, noiselessness, and zeroemission, predestinate their use not only in rural areas without any grid connection. It should be applicated for urban houses under the condition that there is the aim for replacing a very long grid connection and/or for economizing the energy consumption. Moreover as we have seen the serious power failures in the public grid occured even in developed countries will open a new demand.
The paper presents systems realized in the range of 1 and 60 kW in stationary and mobile use. The Stralsund University offers education in this field.
