Daimler Truck has marked a decisive turning point in the world of heavy transport with the launch of the Mercedes-Benz NextGenH2. This hydrogen truck, which promises a range of over 1,000 km, positions itself as a key player in zero-emission transport. With a limited production of 100 units starting in 2026, it is set to challenge diesel trucks on their own turf. Hold on, the future of heavy transport is coming in leaps and bounds!
A Major Technological Advancement
The Mercedes-Benz NextGenH2 Truck is not just a simple update of the GenH2 project; it embodies a true evolution in the field of hydrogen trucks. This vehicle has been designed to integrate solutions from mass production while adhering to the fundamental technical principles of its predecessor. Daimler Truck bets on liquid hydrogen, which, at -253 °C, offers an energy density far superior to that of gaseous hydrogen. This technology allows for ranges exceeding 1,000 km, while maintaining performance comparable to that of diesel trucks.

The storage system is ingeniously designed with two interconnected liquid hydrogen tanks, offering a total capacity of 85 kg. Refueling, which can be done from both sides of the vehicle, takes only 10 to 15 minutes thanks to the sLH2 standard developed with Linde. This approach simplifies the refueling process while ensuring safety and simplicity levels similar to those of diesel, thus increasing logistical efficiency and payload compared to high-pressure systems.
Hydrogen and Electricity: A Winning Duo
At the heart of the propulsion system, the BZA150 fuel cell from cellcentric, a result of collaboration between Daimler Truck and Volvo Group, operates in a “twin system” mode with two units generating a total power of 300 kW. Compactly integrated under the cabin, these fuel cells power electric motors via a high-voltage buffer battery of 101 kWh, designed in-house and using lithium iron phosphate (LFP) technology. This battery plays a crucial role in also storing energy recovered during braking.

The NextGenH2 Truck uses the same electric axle as the eActros 600, paired with a four-speed transmission. This optimizes the operating regime in all circumstances. In Economy mode, the truck can deliver up to 340 kW, while in Power Mode, it reaches 370 kW, providing instant torque and smooth driving, even in challenging conditions.
ProCabin: An Enhanced Driving Experience
One of the standout innovations of this model is the adoption of the new ProCabin, already used in the Actros L and eActros 600. This optimized cabin improves the aerodynamic coefficient by 9% compared to the previous version, thus helping to reduce consumption and improve overall efficiency. According to Daimler Truck, the driving experience is comparable to that of modern electric vehicles, offering top-notch comfort and ergonomics.

The vehicle’s architecture has also been rethought. Thanks to a more compact arrangement of components in the Tech Tower located behind the cabin, the wheelbase has been reduced by 150 mm, reaching 4,000 mm. This allows for better compatibility with a wide range of standard semi-trailers while complying with European length regulations, increasing operational flexibility for customers.

The Tech Tower also integrates a new boil-off management system for hydrogen, compliant with current regulations, allowing the vehicle to be parked in enclosed environments. A dedicated cooling system ensures stable operating conditions, even in extreme temperatures or on particularly demanding routes.
Enhanced Safety and Government Support
In terms of safety, the NextGenH2 Truck relies on the cutting-edge E/E electronic architecture of the eActros 600, integrating the most advanced driver assistance systems such as Active Brake Assist 6, Front Guard Assist, and Active Sideguard Assist 2. Additionally, it meets current cybersecurity standards. A new sensor system also allows for overnight stays in the cabin without risk, even in the highly unlikely event of hydrogen leaks, improving comfort during long trips.

This ambitious project is supported by a total public funding of 226 million euros from the German Federal Ministry of Transport, as well as the states of Rhineland-Palatinate and Baden-Württemberg. Series production of Mercedes-Benz fuel cell trucks is expected to begin in the early 2030s.
