How practical, energy-efficient, ecological and economical are buses with innovative drives in everyday application? The programmatic support research that accompanies the federal government’s bus funding programmes has compiled and evaluated the data and experiences of the transport companies that have been subsidised and summarized them in the final report.

Only by switching to emission-free buses with alternative drives can climate protection objectives be maintained over the coming years. The federal government is therefore pursuing a specific goal as part of the climate protection programme: By 2030, half of city buses must be electric.

To support the switch, the federal government, federal states and the European Union have launched various funding programmes for market launch and ramp-up. The programmatic accompanying research shadows the funded projects and initiatives of the Federal Ministry for Digital and Transport (BMDV) – it bundles the findings and experiences and evaluates them. The goal is to generate a better understanding of the technical and operational suitability of individual zero-emission drive technologies for each of the very particular operating conditions, especially among transport companies and municipal authorities.

The final report of the last phase of the accompanying research summarises the most important findings of the last three years of accompanying research. It is based on detailed operational data and practical experience from participating transport companies, which are evaluated and summarized here.

As part of the accompanying research, additional information was generated for transport companies and municipal authorities that can be downloaded here from the new jump-starter set:

  • Guide to initial information on zero-emission bus systems
  • The online decision tool helps transport companies that wish to convert to alternative drive systems to choose the right type of drive
  • An analysis of the BMDV-funded e-mobility concepts with a public transport focus
  • A project and funding overview
  • A legislative map of electric mobility in public transport (in preparation)
