Volvo Trucks has taken a major step toward sustainable transport by initiating on-road testing of heavy-duty trucks powered by hydrogen combustion engines, reinforcing its long-term ambition to achieve net-zero CO₂ emissions.
The company revealed that its hydrogen-powered trucks are expected to deliver industry-leading performance, combining higher energy efficiency, lower fuel consumption, and enhanced engine power compared to conventional hydrogen combustion technologies.
A key innovation behind this advancement is High Pressure Direct Injection (HPDI), a system that injects a small amount of ignition fuel at high pressure before adding hydrogen. This enables efficient combustion and improved engine performance. Volvo has already proven this technology in its gas-powered trucks, with over 10,000 units sold globally.
According to Jan Hjelmgren, Head of Product Management at Volvo Trucks, the ongoing road trials mark a crucial milestone. He emphasized that the hydrogen trucks are designed to match diesel vehicles in terms of drivability, power, and reliability, making them practical for real-world operations.
The hydrogen combustion trucks are particularly suited for long-haul transport and regions where charging infrastructure for battery-electric vehicles remains limited. With an operational range capable of exceeding typical daily driving distances, these trucks offer a viable alternative for heavy-duty logistics.
Importantly, when powered by green hydrogen and renewable fuels such as Hydrotreated Vegetable Oil (HVO), these vehicles have the potential to achieve net-zero CO₂ emissions on a well-to-wheel basis. Under European Union standards, they are classified as Zero Emission Vehicles (ZEVs), further strengthening their environmental credentials.
Volvo’s hydrogen engine technology is derived from its proven diesel platforms, ensuring familiarity for operators while significantly reducing environmental impact. The company plans to commercially launch these hydrogen-powered trucks before 2030.
This initiative is part of Volvo Trucks’ broader three-path strategy toward decarbonization, which includes battery-electric trucks, fuel-cell electric vehicles, and combustion engines running on renewable fuels like biogas and hydrogen.
In addition to hydrogen combustion technology, Volvo is also preparing to introduce fuel cell electric trucks in limited volumes later this decade, offering another zero-emission alternative that produces only water vapor as exhaust.
With increasing pressure on the transport sector to reduce emissions, Volvo Trucks’ multi-technology approach highlights its commitment to providing flexible, scalable solutions tailored to varying infrastructure and energy availability worldwide.
