CEA “TOTEM” Demonstrator of energy autonomy, support for R&D projects and innovation showcase

PowiDian was selected by CEA TECH, the “technological research” department of the atomic energy and alternative energies commission, for the supply and installation of inter-seasonal energy storage, based on “hydrogen to make its new building, located in Labège near Toulouse, autonomous.

The TOTEM building is a pilot site for energy autonomy. The CEA aims to create an operational base made up of mature technologies, providing a robust and attractive environment.

In order to meet the requirements of this project, PowiDian is installing a turnkey long-term storage system, more commonly known as “hydrogen batteries” consisting of the following elements:

• an electrolyser, a fuel cell,
• a hydrogen storage of 100 kg at 200 bars

Thanks to this achievement, PowiDian is positioning itself as a key player in the CEA’s strategy: “achieving an autonomous platform where energy is consumed with sobriety and efficiency, produced in a renewable way”.
