Overview

• Daimler Buses has launched road trials of the Setra S 517 HD “H₂ Coach” after receiving TÜV approval under Section 19.6 for public testing.
• The technology carrier stores 46 kilograms of hydrogen across two tanks and uses a cellcentric fuel cell rated at 300 kW with an electric motor delivering 320 kW continuous and up to 400 kW peak.
• The converted coach has a permissible gross vehicle weight of 24.7 tons and integrates a battery to buffer energy and support power demand.
• Development is led at Daimler Buses’ Neu‑Ulm coach competence center, leveraging components related to the Mercedes‑Benz GenH2 Truck.
• Daimler Buses outlines a dual roadmap that adds battery‑electric coaches by the end of the decade and moves fuel‑cell coaches toward series production next.
