Our Aix-based company

 

SP3H is an innovative cleantech company based in Aix-en-Provence, at the Technopôle de l’Arbois. Thanks to 18 years of research and development, it has become the world’s leading supplier of highly miniaturised, connected and intelligent optical scanners. In 2022, the FluidBox device was marketed and approved for the heavy goods vehicle and passenger transport (bus and coach) markets.

Our FluidBox solutions promote the deployment of new generations of cleaner fuels, e-fuels and synthetic fuels, for both professional and private users, to meet current and future environmental challenges.

The FluidBox

 

The FluidBox, drawing on advanced techniques from the refining sector, is an intelligent miniaturized optical scanner using near infrared (NIR) technology to identify in real time the molecular structure of fluids, including fuels, biofuels and synthetic fuels.

This advanced sensor enables real-time monitoring of fuel quality, optimizing vehicle performance and significantly reducing CO2 emissions. It can detect and distinguish fuel mixtures, a crucial capability for compliance enforcement.

SP3H at the E-Fuels Summit Europe 2025 – A key event for the future of alternative fuels!

We are pleased to announce the participation of Alain LUNATI, Managing Director of SP3H, as a speaker at the 2ᵉ edition of the E-Fuels Summit Europe to be held in Frankfurt on May 19 and 20, 2025.

At SP3H, we are fully committed to this transition by developing solutions that enable:

– Compliance with post-2035 European regulations on emissions and alternative fuels.
– Real-time traceability of fuels via our FluidBox technology, which instantly identifies the biofuels and e-fuels content.
– Optimized use of renewable fuels, ensuring their integration into existing fleets.
– A response to the requirements of CSRD and RED III regulations, which impose precise monitoring of CO₂ emissions.

For over three years now, our FluidBox technology has been deployed in France’s truck and bus fleets, playing a key role in the certification and recognition of 100% renewable, synthetic and biofuels by the French authorities.

Join us in Frankfurt on May 20, 2025 to find out more about these technological advances and the prospects offered by alternative fuels in the transport sector’s energy transition. 📅
