While hydrogen production is expensive, it can contribute to emission-free mobility. A prerequisite, however, is that the electricity needed for its production and for the transport of this fuel to filling stations should also be powered by renewable energy sources.

One problem is the fact that there is currently no efficient system for storing hydrogen. In existing cars it is stored in gas tanks at a pressure of 700 bar. This is not only an expensive method, but technically challenging as well. The use of magnesium-nitrogen could offer an alternative for the storage of solid fuels.
