We offer a full range of solutions for Hydrogen Engine Hardware & Software, up to the complete integration into your products.

About our
H₂ Engine Solutions

The highly-skilled workforce at Dumarey Hydrocells have used all our gathered experience in engine and controller development to create a full range of Hydrogen Engine and Software solutions. We believe that in order for the world to continue its progression towards sustainable energy, it is imperative that we have effective and practical solutions for decarbonizing a wide range of applications (on-highway, off-highway, marine). In doing so, we can combine the cleanliness of hydrogen with the tested efficiency and convenience of well-established engine technologies, leveraging their wide industrial footprint, skilled workforce, as well as the servicing network.  

Read on to find out how our team are developing — from concept to full-scale production — the technologies which will enable the complete integration of hydrogen solutions into your products.

The Engine Control Unit
(HW & SW) for H₂-ICE

The Dumarey Electronic Platform is a 12V/24V Electronic Control Unit with high integrated drivers for Solenoid Control Valves (boosted and battery direct), DC Motors controller, flexible analog and digital sensors signal acquisition, CAN, LIN, SENT and Ethernet communication busses using a hexacore microprocessor.  

With multi-purpose electronic controller based on flexible and scalable Hardware / Firmware and real-time embedded SW algorithms, it can control multiple types of propulsion and energy systems. This modular SW approach, AutoSAR based, is compliant with even the strictest automotive safety standards and cybersecurity requirements. It uses high-end connectivity to collect and transfer acquired data to the Cloud for data-driven analysis, such as fleet monitoring, root cause analysis and predictive maintenance.
