Mercedes-Benz NextGenH2: Daimler Deploys 100 Hydrogen Trucks on German Roads
A breakthrough in the hydrogen revolution is becoming a reality. Daimler Truck AG has announced plans to deploy a fleet of 100 Mercedes-Benz NextGenH2 units. These giants, powered by liquid hydrogen ($LH_2$), will reach selected customers as early as late 2026, setting a new benchmark for zero-emission heavy-duty transport.
Next Generation: What Powers the NextGenH2?
The NextGenH2 is an evolution of the proven GenH2 prototypes, which have already covered over 225,000 kilometers in real-world logistics operations. Daimler has gone far beyond a simple name change. The new version features:
- Enhanced Insulation System: A critical component for handling liquid hydrogen, which must be stored at approximately -253°C.
- Increased Storage Capacity: Allowing for ranges comparable to traditional diesel engines while maintaining zero tailpipe emissions.
- Cellcentric Technology: Fuel cell systems developed through the joint venture with Volvo Group.
- Modern ProCabin: An aerodynamic design shared with the eActros 600, improving efficiency and driver comfort.
Why Liquid Hydrogen ($LH_2$)?
Daimler consistently favors liquid hydrogen over gaseous hydrogen ($GH_2$) due to its significantly higher energy density. This allows trucks to carry more fuel in smaller, lighter tanks, directly translating to higher payload capacity and a range exceeding 1,000 km on a single tank.

From the Lab to the Highway
Production of the limited 100-unit series will take place at the Wörth plant. Rather than relying solely on track testing, Daimler is focusing on the „living tissue” of logistics. The trucks will go to partners who will generate real-world operational data.
„This is a critical milestone on the road to mass production, which we plan for the early 2030s,” emphasized Daimler Truck representatives.
Technical Specification & Key Innovations
The Mercedes-Benz NextGenH2 Truck integrates proven components with cutting-edge serial technology:
- Cellcentric Fuel Cell: The BZA150 twin-system provides a combined output of 300 kW.
- Serial Components: It utilizes the e-axle, ProCabin, and Multimedia Cockpit Interactive 2 from the battery-electric eActros 600.
- Buffering System: A 101 kWh LFP (Lithium-iron-phosphate) battery acts as a buffer, supporting the fuel cell during acceleration and recovering energy through braking (recuperation).
| Feature | Mercedes-Benz NextGenH2 | Standard Diesel |
| Range | Over 1000 km | 1000-1200 km |
| Fuel | Liquid Hydrogen ($LH_2$) | Diesel |
| Refueling Time | 10-15 minutes | 10-15 minutes |
| CO2 Emissions | 0g (only water vapor) | High |
The sLH2 Refueling Standard
Thanks to the sLH2 (subcooled liquid hydrogen) standard developed with Linde, refueling takes only 10–15 minutes and is as safe and simple as refueling with diesel. This technology is currently being developed as an ISO standard, potentially making it an open solution for the entire transport industry.

Strategic Context: Politics Meets Industry
In Berlin, Daimler Truck CEO Karin Rådström met with Federal Minister of Transport Patrick Schnieder to discuss the decarbonization of the transport sector. The meeting highlighted the necessity of a coordinated market rollout of green technologies.
Key strategic points discussed:
- Dual Track Strategy: Parallel development of both Battery Electric Vehicles (BEV) and Fuel Cell Electric Vehicles (FCEV) to suit different logistical profiles.
- Infrastructure Requirements: Ambitious CO2 reduction goals must be matched by the rapid expansion of hydrogen refueling networks.
- Regulatory Support: The extension of toll exemptions (Maut) for zero-emission trucks in Germany until mid-2031 provides essential planning security for transport companies.
Operational Facts and „Insider” Trivia:
- Real-World Reliability: The 225,000 km already covered by prototypes included partners like Amazon, DHL, and Holcim, proving the technology works in heavy-duty daily operations.
- The „Tech Tower”: In the NextGenH2, the technology tower behind the cab has been streamlined. This shortened the wheelbase to 4,000 mm, ensuring compatibility with standard European trailers.
- Hydrogen Record Run: In late 2023, a GenH2 truck weighing 40 tons proved the technology’s potential by driving 1,047 km on a single tank of liquid hydrogen.
