Hydrogen HPDI Fuel System Development and Validation

Design, engineering, and manufacturing of modular alternative fuel systems for heavy transport using high-pressure direct injection (HPDI) technology

Truck manufacturer

Natural gas and alternative fuel systems

A modular alternative fuel system that enables internal combustion engines to operate on hydrogen as a primary fuel source. The hydrogen variant maintains the core architectural design of the proven LNG/bioLNG HPDI platform while achieving near-100% CO2 reductions versus diesel engines.

On-road testing program of Cespira's hydrogen HPDI fuel system integrated into Volvo heavy-duty trucks. The project aims to validate hydrogen-powered truck performance, efficiency, and operational characteristics prior to commercial launch.

A modular high-pressure direct injection fuel system that enables internal combustion engines to operate on hydrogen as a primary fuel source. The system achieves near-100% CO2 reductions compared to diesel engines while maintaining range, performance, and drivability comparable to traditional diesel powertrains. The hydrogen variant leverages the proven core architecture of HPDI systems already deployed in over 10,000 Volvo trucks operating on LNG and bioLNG.

An established and commercially proven high-pressure direct injection fuel system for liquefied natural gas and bio-LNG applications. Over 10,000 Volvo trucks are equipped with this technology, providing a proven platform from which the hydrogen variant has been developed.
