About FlexFuel

The patented French technology behind every CarbonTech clean.

FlexFuel engine decarbonising (decalaminage)

A French clean-tech pioneer

FlexFuel Energy Development is a French manufacturer that has built engine-decarbonisation machines since 2004. Its systems clean the combustion engines of cars, commercial vehicles and even ships, and the company has expanded rapidly across key European markets and the UK in recent years.

Why the technology matters

As emissions laws tightened, car makers had to fit carbon-trapping devices — catalytic converters, diesel particulate filters (DPFs) and EGR valves. They cut emissions, but they also clog over time, dragging down performance and reliability. FlexFuel’s machines clean those systems and the engine itself, restoring efficiency without replacement.

Patented technology

FlexFuel invests around 10% of its turnover in research and development and holds worldwide patents — including its EGR Pilot® and I-Connect® technology — that let the Hy-Carbon machines automatically adapt each treatment to the specific engine. That’s the same equipment we use at CarbonTech.

Trusted worldwide

By 2024 FlexFuel had grown to over 4,000 distribution points across France and the wider EU, and it continues to grow quickly as environmental regulations tighten around the world.
