Volvo Trucks is accelerating its decarbonization strategy with the launch of on-road trials for hydrogen-powered combustion engine trucks. The initiative marks a significant step toward achieving net-zero CO2 emissions in long-haul and heavy-duty transport.
Hydrogen Combustion Meets High Efficiency
At the core of Volvo’s hydrogen trucks is High Pressure Direct Injection (HPDI) technology, developed in collaboration with Cespira. This system uses a small amount of ignition fuel injected at high pressure to initiate combustion before hydrogen is introduced, enabling efficient and controlled energy release.
The result is a powertrain that delivers:
– Higher energy efficiency
– Lower fuel consumption
– Increased engine power and torque
This approach builds on proven technology already deployed in over 10,000 gas-powered Volvo trucks worldwide, reinforcing confidence in reliability and real-world performance.
Diesel-Like Performance with Lower Emissions
Volvo’s hydrogen combustion trucks are engineered to behave much like conventional diesel vehicles, offering familiar drivability while significantly reducing CO2 emissions. Derived from existing diesel powertrains, the technology ensures operators do not need to compromise on performance or usability.
When powered by green hydrogen and renewable ignition fuels such as HVO (Hydrotreated Vegetable Oil), these trucks have the potential to achieve net-zero CO2 emissions on a well-to-wheel basis. Under EU standards, they are classified as Zero Emission Vehicles (ZEVs).
A Solution for Long-Haul Transport
Hydrogen combustion trucks are particularly suited for long-distance operations, regions with limited EV charging infrastructure and applications where fast refueling is essential.
Their extended operational range meets or exceeds many customers’ daily driving requirements, making them a practical alternative to battery-electric trucks in demanding logistics scenarios.
