The project calls for 5.2 billion euros in total investments to build a factory to produce solid-state electric batteries starting in 2026. The factory is expected to employ 3,000 people directly and support another 12,000 in the region.
"It is an aid for investment which will allow us to strengthen our research and innovation efforts," ProLogium Europe President Gilles Normand said.
The French economy ministry said "this investment shows the success of the strategy for France to catch up in batteries: this factory will produce one of the most technologically advanced batteries in the world."
The French government has set a target of producing two million electric vehicles per year by 2030, and Europe overall is seeking to boost domestic production of the key component of electric vehicles.
France's first electric vehicle battery factory opened in May. Including the ProLogium there are currently plans to build another three in the northern French region.
