Our Shareholders


CEA Investissement is the strategic investment fund of the CEA, which has supported more than seventy start-ups since 1999.


The CEA is one of the world’s leading research organisations when it comes to the development of technological bricks for use in the hydrogen sector. As part of a bilateral project, Symbio has been able to benefit from their expertise and remain a key partner in zero emissions transport.

A leader in the energy revolution, ENGIE offers an extensive range of cleaner transport solutions. With regards to hydrogen, the group was one of the founding members of the “Hydrogen Council” – an international association which promotes the use of hydrogen as an ideal vector for energy transition.


In France, ENGIE and Symbio are both involved in the “Zero Emission Valley” project, coordinated by the Tenerrdis Hub, which aims to industrialise the production of hydrogen kits for use in transport and to operate around 1,000 hybrid utility vehicles in the Auvergne Rhône-Alpes region. ENGIE provides its expertise when it comes to the production of carbon-free hydrogen and distribution infrastructure. The Group organises special events relating to hydrogen transport.

A world leader in tyres, Michelin continue to innovate to promote the transport of today and to invent the transport of tomorrow.


As far as Michelin is concerned, hydrogen ticks all of the boxes with regards to sustainable transport (impact on CO2 emissions, air quality, energy transition), while tackling all of these uses. The Group has been working in this field for more than 15 years, becoming a shareholder in Symbio in 2014. Michelin and Symbio also became involved in the “Zero Emission Valley” project in the Auvergne Rhône-Alpes region (20 hydrogen stations and 1,000 vehicles by 2020).
