Concrétiser ces recherches en innovation !
Industrialization of EES-related discoveries (batteries/supercapacitors)
takes place abroad (even if discoveries are French/European)
BUT
France has world-leading companies in the field of energy storage (users AND
suppliers: Saft, Blue Solutions, Renault, EDF, Airbus, Solvay…) as well as
innovative start-ups.
AND
Excellence and versatility of French research labs on EES.
Research network on electrochemical energy storage (RS2E)
Initiated in 2011 by CNRS and Ministry of Research under the proposition of J.M. Tarascon
11
RS2E GOALS FOR EES IN FRANCE
• Create a continuum between scientific discoveries and commercial products
• Be an active part of a lucrative and growing market (Li-ion market expected
to double in 2017 at 24 billion $)
• Promote and fund breakthrough researches (unlock and discover)
• Sharing ideas amongst a wide array of partners from different backgrounds
• Share human resources and equipment
