What Happened
Volvo's hydrogen-powered trucks feature High Pressure Direct Injection (HPDI), a technology that injects a small amount of ignition fuel at high pressure to enable compression ignition before hydrogen is added. This results in higher energy efficiency, lower fuel consumption, and increased engine power compared to conventional hydrogen combustion engines. Volvo already uses HPDI in its gas-powered trucks, with over 10,000 units sold globally.

Demonstrates proven performance of the technology.
“On-road testing is an important milestone for our hydrogen combustion engine trucks. I feel confident that they will be the best in the industry if you look at fuel efficiency, power, torque and drivability. Customers will be able to operate them just like diesel trucks. Our experience with HPDI technology in more than 10,000 gas-powered trucks is strong proof of its performance.”
- Battery-electric trucks
- Fuel-cell electric trucks
- Combustion engines using renewable fuels like biogas and HVO
Why this matters
Hydrogen combustion trucks offer a zero-emission solution for long-haul routes where battery-electric charging is impractical, complementing Volvo's three-path decarbonization strategy.
