TotalEnergies’s innovation and research center will support and accelerate the Group’s shift to carbon-free energy, with the goal of becoming carbon-neutral by 2050. It will house innovation and research programs that require shared infrastructures and can benefit from Saclay’s ecosystem. With its proximity to head offices, this site will be a complement to existing research centers. 

  • Le concours d'architecte

The building’s 12,500 sq. m will be occupied by some 400 individuals, half of whom will be external to the Group (partners, doctoral students etc.). The spaces will be welcoming and modular to best facilitate connections and sharing. The center will be made up of office spaces, laboratories, spaces for experimentation and common areas suitable for multidisciplinary work in project mode. It will bring together Group teams, partners and clients with a co-innovation approach.It will also be a life-size testing site for technology Total has developed in energy systems (such as solar panels, batteries and micro-networks) and transportation (charging stations and associated services

A DIALOGUE WITH actors of saclay plateau

TotalEnergies has maintained ongoing dialogue througout the project. Many co-design and concertation workshops were held in 2019. Then a monitoring committee was set up in 2020 with Ecole polytechnique students. The comments generated at these events have led to adaptations such as limiting areas open to public and locating the center off of the École Polytechnique campus.




TotalEnergies will set up its innovation and research center alongside other businesses (TBD) in the innovation business park located east of the École Polytechnique district ZAC (joint development zone).

This park is located off of the École Polytechnique campus, in an area managed by the Paris-Saclay public development authority. It is part of the Paris-Saclay urban area land-use plan designed in 2012.

Thales, EDF, Danone and Horiba already have a presence in the École Polytechnique district. The École Polytechnique’s incubator, the Drahi X-Novation Center, hosts a range of businesses, including startups and teams belonging to Valeo and Fujitsu.

It is common to see innovation hubs attracting businesses (Grenoble, Lausanne, California, Boston, Montreal, Cambridge, Bombay, Singapore etc.).
