Abstract: For long-time-storage problems of electrical energy, hydrogen-storage-systems have some significant advantages. In photovoltaic systems, especially in island-applications, they can help to solve the seasonal storage problem with solar energy and a not correlated energy demand. In summer the surplus of photovoltaic energy is used to produce hydrogen-gas by water electrolysis. In winter the hydrogen is converted back to electricity with a fuel-cell at high efficiency. This usually needs extensive system technology and therefore it is only useful for complex photovoltaic systems.
