Abstract

Dispense with fossil fuels and stay mobile at the same time - how this challenge can be solved technically is discussed by experts from industry and science. There are a number of options available with hydrogen and fuel cells, batteries or synthetic fuels. At the colloquium they will be examined for their suitability for different applications. What is the current state of technology, which potential do they contain, and how can the mobility change be shaped with the help of these building blocks? Inform yourself and discuss the mobility of tomorrow with competent experts. Mobility is indispensable in our modern society - but today it is also hotly debated. Under the pressure of the Paris climate protection goals solutions are sought, the global CO 2Emissions from the transport sector. In the end, the complete abandonment of fossil fuels from the year 2050 stand. These goals can only be achieved with a basic mobility turnaround. But the way to clean and sustainable mobility is controversial and the subject of some emotionally charged debates. While automotive industry policy is currently favoring battery-powered vehicles (BEVs), others see the future in fuel cell vehicles (FCEVs) powered by hydrogen. Another option is the classic internal combustion engine, which uses climate-friendly synthetic fuels (e-fuels). All these technological solutions have advantages and disadvantages: The high efficiency of pure battery operation is the range problem, the extraction of raw materials for the batteries and long loading times. The fuel cell vehicle scores with its long range, fast refueling and local zero emissions, but it needs a hydrogen infrastructure and is - at least for now - (too) expensive. Another way to use hydrogen is via e-fuels: these are synthetic fuels derived from CO2 and electrolysis hydrogen are produced. While their overall efficiency is lower than direct use of hydrogen or green electricity, the existing vehicle fleet and existing infrastructure can continue to be used. The perfect, cost-effective and all-encompassing solution for sustainable mobility is not in sight. How can the existing and new technologies be combined in such a way that they provide a complete and practical picture of the turnaround in mobility? We want to come closer to this answer with the special colloquium.
