What is the Retrofit Hydrogene Project?
Retrofit Hydrogene is an innovative European startup based in Auxerre, aiming to revolutionize heavy mobility by converting existing diesel engines to run on hydrogen fuel. This project offers a powerful and clean engine solution that uses hydrogen as fuel for various applications. Unlike costly battery or fuel cell technologies, Retrofit Hydrogene provides an affordable and practical alternative that can be implemented now—no waiting required. The core idea? Modify diesel engines with a patented system that combines hydrogen and water injections, making combustion more efficient and drastically reducing emissions. This retrofit approach is designed to be carried out by existing maintenance workshops, keeping costs low and accessibility high.
Main Benefits of Retrofit Hydrogene
Here’s what makes this project stand out:
- Retrofitted engines deliver the same or even better power, torque, and efficiency compared to modern diesel engines.
- Instant reaction to power demands, ensuring smooth and responsive performance.
- Does not require pure, expensive hydrogen like fuel cells do.
- Adaptable to the heaviest vehicles—think trucks, buses, trains, boats—and even generators.
- Emits only water vapor and minimal traces of NOx, thanks to a patented double injection system of hydrogen and water.
- Fuel efficiency exceeds that of the original diesel engine, with efficiency rates over 50%, leading to significant fuel savings.
- Cost-effective retrofit compared to electric conversions or new fuel cell systems.
How Retrofit Hydrogene Works
The magic lies in the patented technology that injects hydrogen and water directly into the combustion chamber. This double injection system improves combustion efficiency and drastically cuts down NOx emissions—by a factor of ten! Plus, since hydrogen combustion produces no CO2, the entire process is fully decarbonized. The retrofit doesn’t just swap fuels; it transforms the engine’s performance and environmental footprint. And the best part? It’s simple enough for existing workshops to handle, making it a practical solution for today’s urgent decarbonization needs.
Applications Across Heavy Mobility and Power Generation
Retrofit Hydrogene isn’t just a one-trick pony. It’s designed for a wide range of uses. Heavy vehicles like trucks, buses, trains, and boats can all benefit from this technology, especially where high torque and power are essential. The solution also extends to power generation, offering a powerful alternative to traditional diesel generators. The prototype’s performance suggests autonomy comparable to electric vehicles, making it a viable option for both mobility and stationary power needs.
Why Retrofit Instead of New Engines?
Building new hydrogen engines or switching to fuel cells can be prohibitively expensive and time-consuming. Retrofit Hydrogene offers a clever shortcut: upgrade what’s already there. This approach slashes costs and deployment time, making zero-emission heavy mobility accessible right now. Plus, it sidesteps issues like sensitivity to ambient atmosphere parameters, which can affect other hydrogen technologies. In short, it’s a smart, practical, and scalable way to accelerate the journey toward decarbonization.
