The Mercedes-Benz NextGenH2 Truck is the next evolution in hydrogen-powered heavy transport from Mercedes’ commercial vehicle division, Daimler Truck. Designed for long-haul freight operations, this fuel-cell semi-tractor takes hydrogen propulsion to a production-ready level.
Release and Production Timeline
Mercedes-Benz has confirmed that small-series production of the NextGenH2 Truck will begin by the end of 2026, with 100 vehicles destined for early customer use at launch.
This limited run paves the way for larger scale series production in the early 2030s, aligning with broader industry goals for net-zero freight transport.
Key Features & Highlights
Hydrogen Fuel Cell Powertrain
The NextGenH2 Truck uses a hydrogen fuel cell system where hydrogen and oxygen react to generate electrical energy for propulsion. This setup produces zero tailpipe emissions beyond water vapor, making it a strong candidate for sustainable long-haul transport.
At the heart of the powertrain is the cellcentric BZA150 fuel cell, which is configured in a dual-unit system with a total output around 300 kW.
Long Driving Range & Fast Refueling
One of the standout features is its range of over 1,000 kilometres on a single hydrogen fill — rivaling conventional diesel trucks and addressing a key limitation of battery-electric alternatives.
Refueling takes roughly 10–15 minutes using the sLH₂ standard, similar to refueling time for diesel, making long trips viable without lengthy downtime.
Performance & Power
The NextGenH2 Truck delivers robust performance suitable for heavy freight:
- Power Modes: Up to ~340 kW in Economy Mode and 370 kW in Power Mode for demanding drives.
- Energy Buffer: A 101 kWh lithium-iron-phosphate (LFP) battery serves as a buffer to support the fuel cell, especially during braking or downhill energy recovery.
- Electric Drive: Uses an integrated e-axle with 4-speed transmission borrowed from Mercedes’ eActros 600 series.
The combination of fuel cell and battery allows smooth power delivery and responsive torque, even under high loads or steep terrain.
Design & Technology
ProCabin & Driver Experience
The truck features the aerodynamically optimized ProCabin, which improves overall efficiency by lowering drag compared to the previous generation.
Inside, the Multimedia Cockpit Interactive 2 offers modern connectivity and driver assistance interfaces, bringing truck cabin technology on par with advanced electric models.
Safety & Driver Assistance
NextGenH2 also incorporates the latest safety systems used on series-production Mercedes trucks, such as:
- Active Brake Assist 6
- Front Guard Assist
- Active Sideguard Assist 2
- Advanced cybersecurity standards
Innovations in hydrogen handling include robust boil-off management and leak sensors — enabling safer operation and even overnight stays in the cab when needed.
Operational & Customer Benefits
Compatibility and Flexibility
By reducing the size of the “Tech Tower” behind the cab and shortening the wheelbase to around 4,000 mm, the NextGenH2 Truck can pair with a wider range of trailers within EU length limits.
This design choice improves flexibility for different freight applications without sacrificing hydrogen storage or performance.
Production Location
Small-series trucks will be manufactured at the Mercedes-Benz plant in Wörth, Germany, marking a significant step toward industrialized hydrogen truck production.
Why the NextGenH2 Matters
The NextGenH2 Truck blends zero-emission operation with real-world practicality for long-distance freight. Its hydrogen fuel cell system addresses two major barriers for sustainable transport: range and refueling time.
While broader hydrogen infrastructure and lower fuel costs remain challenges, this truck represents an important milestone in decarbonizing heavy transport and reducing dependence on diesel.
