Paris/Turin, 26 January 2026 — Dumarey returns to Hyvolution for the fourth year in a row, reinforcing its position as a comprehensive engineering partner in hydrogen technologies. This year, the Company showcases an expanded portfolio of hydrogen-focused engineering services, supported by real use cases developed in collaboration with selected partners.
Dumarey’s mission is clear: accelerating hydrogen adoption by bringing to the fair concrete demonstrators, advanced capabilities, and control platforms ready for seamless integration into vehicles and energy systems.
Dumarey provides end-to-end engineering services dedicated to fuel cell systems and hydrogen internal combustion engine solutions , including system architecture, sizing and design, advanced thermal management, calibration and validation, integration into both mobility and stationary applications. These services are designed to support a broad spectrum of hydrogen technology solutions.
Use cases at the booth: from concept to validation
Visitors at Hyvolution can explore real demonstrators showcasing Dumarey’s ability to deliver complete engineering programs — from concept definition to system validation — including:
– 100% Hydrogen Internal Combustion Engine (H2 ICE)
Displayed as a technical demonstrator, the hydrogen engine highlights Dumarey’s capabilities in H₂ ICE architecture, integration, control strategies, calibration and validation. This is not a commercial product, but a proof of Dumarey’s execution capabilities across full H₂ ICE development programs.
– Fuel Cell Hybrid Drone – FC4Drones (cofounded project)
Developed with our partner MAVTech, this fuel cell hybrid drone demonstrates Dumarey’s expertise in propulsion integration, control development, and energy management for next generation aerial systems. Thanks to hydrogen hybridization, the drone achieves significantly extended flight duration compared to traditional battery powered platforms.
Introducing Dumarey’s proprietary control solutions
Dumarey brings on stage its suite of advanced, in-house d eveloped control platforms engineered to elevate performance across energy and mobility systems:
– Vehicle Control Unit (VCU) / Fuel Cell Control Unit (FCCU)
A highly adaptable control solution supporting electrified, hybrid, and fuel cell applications, suitable for passenger cars, commercial vehicles, and off-highway machinery.
– Engine ECU (Electronic Control Unit)
A next generation propulsion ECU built on more than 20 years of expertise, part of the Dumarey Electronic Platform — setting new industry benchmarks for performance, reliability and innovation.
Hydrogen PFI Injection System
Dumarey also showcases its Hâ‚‚ PFI Injection System designed in cooperation with Liebherr, part of its portfolio of hydrogen fuel supply solutions specifically developed for internal combustion engines, suitable for on-road and off-road heavy duty applications.
