New power train technologies, such as electric drives, play a central role in achieving the climate protection goals: The reduction of CO₂ emissions in the transport sector by 40% until 2030 compared to 1990 will only be possible if the use of alternative drives and energy sources becomes an essential component. Hydrogen fuel-powered fuel cell vehicles represent a solution for the mobility sector, as fuel cell vehicles offer a greater range than battery-electric vehicles with a higher payload and they can be used in commercial vehicles as well as in public transport. There are currently considerable disadvantages for a market ramp-up, such as the comparatively low efficiency of fuel cell systems, the lack of infrastructure at hydrogen filling stations and the high purchase price.
