Mercedes-Benz NextGenH2 Truck
Daimler Truck's liquid-hydrogen fuel-cell tractor: 300 kW of fuel cells, 85 kg of hydrogen, well over 1,000 km per filling, 10 to 15 minutes to refuel. It cannot be set against a diesel yet: it is not for sale (100 trucks go to selected customers in Germany from the end of 2026), there is no price, Daimler has not published hydrogen use for this truck, and liquid-hydrogen filling stations are still very few.
Battery101 kWh
Range1000 km
