Hydrogen is seen as a possible energy carrier for the traffic of tomorrow. Its potential for a virtually pollution-free chemical conversion in fuel cells and conventional combustion engines, as well as its CO2 neutral production using renewable energies from the basis for a future-oriented and sustainable mobility concept. In order to achieve market penetration, a comprehensive hydrogen infrastructure needs to be established. That is why extensive resarch and demonstration projects regarding the creation of a hydrogen filling station grid are conducted in addition to the development activities undertaken by the automotive industry.
A number of different hydrogen-powered vehicle fleets are already being tested in public transport scenarios. At the moment, however, Germany and Europe both lack the appropriate infrastructure. For test activities, a flexible and reliable supply is necessary even in regions without direct access to hydrogen filling stations. At the moment, this supply gap is closed by the gas providers, who ensure the refuelling of the vehicles by providing large gas bottles and tanks.
The HyTra system, a development of the Fraunhofer IVI, was designed as a novel, highly flexible alternative to stationary H2 production facilities.
