Daimler Buses has introduced a groundbreaking development in public transport with the eCitaro G articulated electric buses featuring hydrogen fuel cell technology. The new driving mode, known as H2 mode, allows these buses to exclusively operate using hydrogen fuel cells, eliminating the need for external battery charging and significantly increasing operating range and efficiency. This innovation marks a shift from the previous model, where the fuel cell system could only act as a range extender. Each bus is equipped with four NMC3 battery packs, improved regenerative brake charging, and six hydrogen tanks on the roof, enabling enhanced performance in urban traffic and challenging terrains. The collaboration between Daimler and SSB Stuttgart signifies a commitment to sustainability, with plans to operate emission-free buses in the city center by 2027. The deployment of these buses in Stuttgart showcases a focus on passenger comfort and safety, with features like rear cameras, surveillance systems, accessibility ramps, and specialized areas for wheelchairs and prams. The introduction of these hydrogen-powered buses not only revolutionizes public transport but also sets a new standard for sustainable urban mobility.
