Taiwan-based battery manufacturer ProLogium Technology has held the groundbreaking ceremony for its European gigafactory in Dunkirk, France. It is the company’s first manufacturing facility outside Taiwan. The Dunkirk site is intended to manufacture ProLogium’s fourth-generation all-inorganic solid-state lithium ceramic batteries.

The company plans to deploy an industrial-scale mass-production platform designed to balance safety, performance, and manufacturability. The technology is based on a fully ceramic electrolyte architecture that aims to combine the benefits of solid-state and liquid-type batteries. The project supported by public initiatives such as “France 2030” and the “Green Industry Act” is expected to create jobs, support electrification, and reduce reliance on non-European battery technologies.

According to the project roadmap, the first phase of the factory is scheduled to start operations in 2028 with an initial capacity of around 0.8 gigawatt-hours. Capacity is expected to increase to four gigawatt-hours by 2030 and to twelve gigawatt-hours by 2032. In the long term, the site could be expanded to up to 48 gigawatt-hours, subject to market demand.

ProLogium claims it selected Dunkirk for its industrial ecosystem, logistics connectivity, and access to low-carbon energy. The site benefits from maritime, rail, road, and inland waterway connections, as well as proximity to the Gravelines nuclear power plant. The region is positioning itself as a growing decarbonized industrial cluster focused on batteries and energy transition.
