Metier Technologies and MAHLE Powertrain will showcase a newly developed H₂-powered commercial vehicle, demonstrating how their joint technologies enable the rapid conversion of existing diesel trucks to run on 100% H₂ fuel. The demonstration vehicle features a 6.7-litre, 6-cylinder engine in a DAF LF220 platform, converted to H₂ technology through the partnership.

"This project will demonstrate what can be achieved when engineering expertise meets urgent environmental needs," said James Budgett, Managing Director of Metier Technologies. "Working with MAHLE Powertrain's established control technology, we've proven that existing diesel trucks can be rapidly converted to H₂ power, offering depot-based fleet operators a practical, commercially viable pathway to zero-emission transport without waiting for entirely new vehicle platforms."

The Metier project leverages MAHLE Powertrain's Flexible ECU (MFE) engine control software platform, which has been developed for a wide range of internal combustion engine applications and provides the foundation for rapid H₂ conversion. MAHLE Powertrain's sophisticated control system enables the precise mapping and calibration required for H₂ combustion, whilst its ECU technology ensures optimal performance and safety. Mike Bassett, Engineering Director at MAHLE Powertrain, will touch upon the project as he presents on H₂ ICE design, including combustion CFD and MAHLE Jet Ignition (MJI), at CENEX Expo.

Metier's H₂ internal combustion engine solution offers superior total cost of ownership compared to battery electric and fuel cell alternatives, enhanced capability for longer duty cycles and heavier payloads, as well as zero emissions operation, enabling access to city centers. The company's regional approach targets established H₂ ecosystems in Scotland and the Southwest, working with selected H₂ providers and synchronizing with government H₂ production commitments through 2030.

The transformation process involves integration of specialized H₂ injectors, comprehensive engine mapping using MAHLE Powertrain's MFE platform, and new safety systems. MAHLE Powertrain's new heavy-duty H₂ test bed facility in Northampton has enabled the engine mapping and performance optimization to be completed ahead of CENEX Expo, proving reliability whilst the company's control technology ensures optimal H₂ combustion management.

Following the CENEX event, Metier plans proof-of-concept work with targeted fleets by mid-2026, with volume deployment scheduled for early 2027. Metier is developing partnerships with H₂ suppliers, fleet operators, and leasing companies to create a complete commercial ecosystem.
