FluidBox, the on-board solution that certifies low-carbon fuels in real time
With our FluidBox on-board sensor, profile in real time the actual use of alternative fuels (HVO, B100, XTL, e-fuels) across your entire fleet, without vehicle modification, and ensure your compliance with CSRD Scope 3, RED II & III requirements.

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.

Carbon neutrality by 2050
SP3H is undergoing rapid expansion and growth, initially focused on the industrial and transport vehicle market. The company is now launching its developments in the automotive and aviation markets, in collaboration with major players in the sector. The easy-to-install FluidBOX offers a low-capex solution for retrofitting 300 million vehicles in Europe. This approach aligns SP3H perfectly with the mobility and transport sector’s goal of carbon neutrality by 2050, representing a significant market opportunity while supporting sustainable development initiatives.
Biofuels / Efuels
As part of the energy transition towards carbon-neutral transport by 2050, SP3H is one of the key players offering the technological means to guarantee that every vehicle using biofuels and Efuels achieves the performance it needs to provide an immediate alternative for everyone in the future energy mix.
