In cooperation with individual OEMs and various H2 initiatives, the topic of hydrogen is currently being pursued by SAG in many respects, e.g. the topic of H2 tanks is obvious. At the same time, various other topics are being investigated for which the use of H2 could be of interest. The initiatives will be pursued with Open Innovation in order to sound out as broad a spectrum as possible at the beginning.
The efficient storage of hydrogen is seen as an important prerequisite for the dissemination of fuel cell technology in the transport sector. Since hydrogen has a low volumetric energy density, it is usually carried in compressed form in cylindrical pressure vessels in motor vehicles. In the meantime, 700 bar have established themselves as the storage pressure for passenger cars. For buses, on the other hand, storage space (on the roof) is less scarce. As a result, buses can still use pressure accumulators with only 350 bar.
