Kurzbeschreibung

Hydrogen originating from water and split with solar energy is an excellent means to store, transport and use solar energy. Hydrogen is a carbon-free fuel which oxidizes to water as combustion product. The generated water becomes, together with solar energy as a primary energy source for splitting it, a source of clean and abundant energy in a carbon-free, natural cycle. The main difficulty is to economically produce the hydrogen by water splitting, which requires free energy or high temperatures. The thermodynamics of water splitting is reviewed in the paper. A hydrogen-based, clean energy supply concept comprising the production of hydrogen by hydropower, its transportation to Europe and its storage and use in different forms is feasible today and is described in the paper. The economic aspects are treated in a rather concise manner which the author considers sufficient in the actual, not yet industrialized state of the technology. The paper conveys the message to demonstrate and therewith to start to build now, with existing technology, a clean and abundant energy system which would allow to prevent rather than to cure environmental or oil shortage mishaps.
