Electric bus traffic status in Hessian urban areas - Electric bus transportation scenario in the urban areas of Hesse
In the heart of Germany, cities such as Frankfurt, Kassel, Darmstadt, Fulda, Gießen, Marburg, and Wiesbaden are transitioning towards emission-free bus traffic, with a significant emphasis on battery-electric buses (e-buses).
The adoption of e-buses is on the rise nationwide, with a 68.5% growth in registrations over 8 tons in the first quarter of 2025 compared to 2024. Cities like Frankfurt, with its status as a major urban centre and the European headquarters for JBM Electric Vehicles, are expected to lead the region in electric bus adoption.
Other cities, such as Kassel and Darmstadt, are modernising their public transport fleets and are likely to increase the integration of e-buses. However, specific figures for these cities are not yet clearly stated.
Hydrogen buses, while promising for zero-emission urban transport, face significant barriers like high costs and infrastructure challenges. As a result, their adoption in Hessian cities is limited, with Frankfurt and others appearing to be in exploratory phases.
Natural gas buses, while considered lower-emission compared to diesel, are still prevalent in parts of Germany. However, they are not emission-free and some Hessian cities might still be using them due to cost and feasibility considerations.
In Frankfurt, the shift towards electric buses is well underway, with plans to have 25% of its 440-vehicle bus fleet electric by August, with two-thirds being battery-powered and one-third being hydrogen buses. Darmstadt, on the other hand, has already exceeded EU standards requiring 65% of newly-acquired buses to be emission-free by 2030, with 54 electric buses making up all standard buses and two-thirds of their entire bus fleet.
Wiesbaden, which previously operated hydrogen buses, has realigned its fleet strategy due to space constraints, selling five hydrogen buses to Mainz and five to other customers. The city currently operates 120 solo electric buses and one electric articulated bus, with plans to further increase their use.
Feedback from passengers and staff in Marburg has been extremely positive, with the city operating 11 electric buses, accounting for 20% of their regular bus service. Fulda, too, is increasing its share of electric buses in city traffic, with seven e-buses in operation and six more on order for mid-2026, increasing the share from 23 percent to 42 percent.
The shift towards e-buses comes with higher costs, with an electric bus being approximately twice as expensive to acquire as a diesel bus. However, the Federal Ministry for Economic Affairs and Climate Protection funds 80 percent of the additional costs of a new electric bus compared to a diesel bus and 40 percent of the charging infrastructure.
In conclusion, battery-electric buses are currently the most widely adopted emission-free urban bus technology in Hessian cities. Hydrogen buses hold long-term promise but face considerable challenges and currently have limited deployment in the region. Natural gas buses continue to be used but do not qualify as emission-free. The shift to hydrogen and green hydrogen fuel cell buses is likely to grow only when costs decrease and infrastructure improves significantly.
The community policy in Hessian cities may need to address the higher initial costs of acquiring electric buses, as they are approximately twice as expensive as diesel buses. On the other hand, the employment policy could focus on the growth of jobs within the environmental-science and technology sectors, given the ongoing transition towards emission-free bus traffic, particularly battery-electric buses.
