EMME is a pioneering project dedicated to producing essential battery materials for electric vehicle batteries in France.
The project involves the development of a nickel and cobalt conversion hub, along with a materials science and process engineering laboratory, on the industrial-port site of Parempuyre-Blanquefort, in the Nouvelle-Aquitaine region.
Starting in 2028, this industrial and technical site will supply battery-grade critical materials to European players in electric mobility — supporting a more sustainable automotive industry.
By 2030, EMME aims to cover over 30% of France’s material needs for electric mobility.
Battery supply chain
EMME is positioned at Stage 2 of the battery value chain: Refined materials, and at Stage 6: Second life and recycling. Our process has been specifically designed to handle raw materials recovered from end-of-life batteries, reinforcing our commitment to a circular, low-impact economy.
What’s at stake
Building the industrial capacity and expertise needed to produce high-quality materials for electric vehicle batteries
Cutting the carbon footprint of battery-grade materials to support a cleaner, more sustainable mobility industry
The EMME project is fully aligned with the European Union’s "European Raw Materials Act" (March 16, 2023), which aims to secure Europe’s supply chains for critical raw materials. It also supports the France 2030 strategy, which seeks to position France as a key player in the electric mobility sector.
EMME meets the criteria for green industries as defined by the law of October 23, 2023, and was officially granted "green industry" tax credit approval on December 31, 2024. It has also been recognized as a Project of Major National or European Interest.
