In Stuttgart, Germany, the city's transportation company, Stuttgarter Straßenbahnen AG (SSB), is leading the way towards emission-free public transport by commissioning ten fully electric articulated buses with Mercedes-Benz eCitaro G fuel cell and H2-Mode. These buses aim to pave the way for a climate-neutral bus network in Stuttgart by 2035, with plans to exclusively operate emission-free buses in the city center by 2027. The H2-Mode operational strategy allows the buses to run solely on hydrogen, eliminating the need for stationary charging processes and significantly enhancing operational efficiency and range. Equipped with a 392 kWh battery capacity and hydrogen tanks, the buses also feature modern amenities for passenger comfort and safety, showcasing a major step towards sustainable public transport in Stuttgart. The collaboration between SSB, Daimler Buses, and local authorities emphasizes a shared commitment to environmental sustainability and urban development in the region.
