Abstract
The South Tyrolean Transport Agency (STA) is evaluating the possibilities of converting several hundred buses to zero emissions in the coming years. The terrain of this Alpine region and the local temperature range implies challenging conditions for the applied technology. Bus lines in South Tyrol cover up to 55.2 km (one way) and differences in altitude of up to 1786 hm. Outdoor temperatures can range from -25°C on cold winter days to 40°C on hot summer days. In order to assess the possibilities and limits for replacing current diesel buses, the application of battery electric buses (BEBs) and hydrogen fuel cell electric buses (FCBs) were evaluated by Eurac Research
