February 13, 2026: Taiwan-based ProLogium Technology broke ground on the phased construction of a solid-state lithium ceramic batteries gigafactory in France on February 10.

The Dunkirk facility will be home to production of ProLogium’s European fourth generation ‘superfluidized all-inorganic solid-state lithium ceramic battery’.

ProLogium said the groundbreaking ceremony for its first facility outside Taiwan marked the transition from project planning to execution, thanks to the support of the French government and local authorities.

Completion of the second and final phase of the Dunkirk site, set for 2032, should take total annual production capacity to 12GWh.

ProLogium has secured reserved land around the initial construction site for the potential expansion of the manufacturing plant to 48GWh.

ProLogium will use its Taiwanese gigafactory in Taoyuan, operational since 2024 and having delivered more than 750,000 cells, to support the scale-up of operations at Dunkirk.

Vincent Yang, founder and CEO of ProLogium, said: “We are bringing our mass-production platform to Europe and will build the Dunkirk lines with a platform mindset — from equipment installation and process windows to quality systems — to ensure consistent, industrial-scale output.”

French president Emmanuel Macron said support for the project was an issue of French and European sovereignty, as well as an economic, social, and climate imperative.

Maurice Georges, chairman of the board of Dunkirk Port, said ProLogium’s facility is the second gigafactory to be established in the region, known as the ‘Hauts-de-France battery valley’.

The port is supporting development of the site in establishing a local manufacturing system, covering production, quality, and supply-chain collaboration.
