Mercedes-Benz hydrogen-electrical semi commences testing

Daimler Truck, the commercial motor vehicle sister firm to Mercedes-Benz, has started testing prototypes for a semi-trailer truck driven by a hydrogen-electric powered powertrain.

The prototype is centered on a Mercedes-Benz Actros, but its powertrain could perhaps finish up in trucks and buses from other Daimler Truck makes these kinds of as Freightliner, Western Star and Fuso.

The powertrain could also end up in vehicles from Volvo Team as the Swedish company, which is different to the Volvo motor vehicle corporation, previously this 12 months shaped the joint undertaking Cellcentric with Daimler Trucks to establish and create at scale hydrogen-electrical powertrains for commercial cars.

Very first previewed very last yr in the Mercedes-Benz GenH2 Truck idea, the powertrain consists of a twin-motor procedure wherever just about every motor can provide a constant 308 hp and 1,163 lb-ft of torque and peak 442 hp and 1,527 lb-ft. Normally the motors draw vitality from a hydrogen gasoline-mobile stack but throughout high-load scenarios, power is also drawn from a battery that is held demand. This battery will have a somewhat little ability considering that it will only be applied temporarily, like when the truck is accelerating tricky or climbing a steep hill.

The prototype is fitted with liquid hydrogen storage tanks, selected for the reason that they can be smaller and, due to the lower strain, drastically lighter than tanks required for gaseous hydrogen.

The screening is demanding, as the vans will have to fulfill the similar reliability and longevity prerequisites of present diesel vehicles. This consists of a lifespan of at the very least 750,000 miles more than 10 a long time and a whole of 25,000 hrs of procedure.

There is a good deal of perform to be completed. Daimler Vans designs to start purchaser trials in 2023 but quantity deliveries aren’t anticipated until 2027. Why the hold off? In addition to developing and tests the technologies, there also demands to be a rollout of hydrogen fueling stations ahead of clients will be ready to make the order.

Daimler Trucks is also building battery-electrical trucks for shorter routes and currently has some on sale, like the Fuso eCanter which began creation in 2017. It will launch a bigger Mercedes eActros battery-electric powered truck able of around 124 miles of selection later on this year, and one particular capable of more than 310 miles in 2024. But for supreme variety, for instance additional than 600 miles, Daimler Vehicles is seeking at hydrogen-electric powered powertrains as the option.

In addition to Daimler Vans and Volvo, Standard Motors, Kenworth, Navistar and Toyota are also screening hydrogen-electric semis. Providers like Hyundai and Nikola are also exploring the risk.
