ProLogium breaks ground on Dunkirk gigafactory
- Official groundbreaking and start of construction scheduled for 2026; Dunkirk will be ProLogium’s first facility outside Taiwan.
- Fab 1 Phase 1 will start Gen4 mass production at 0.8 GWh in 2028, with a capacity ramp-up planned for 2029.
- Full operation at 4 GWh is targeted for 2030, with Phase 2 completion reaching 12 GWh by 2032.
- Site can scale up to 48 GWh long term and will leverage the Taoyuan gigafactory experience, which has delivered more than 600,000 cells since 2024.
Project overview
ProLogium has launched construction of a gigafactory in Dunkirk to deploy its Superfluidized All‑Inorganic Solid‑State Lithium Ceramic Battery mass‑production platform in Europe. The site is presented as the group’s first industrial facility outside Taiwan and intended to strengthen a local value chain for next‑generation battery production aligned with European electrification and industrial sovereignty priorities.
Technology and manufacturing
The Dunkirk lines will be designed around an all‑inorganic solid‑state electrolyte architecture to balance safety, performance and manufacturability at scale. ProLogium says the project will follow a platform mindset—covering equipment installation, process windows and quality systems—and draw on its Taoyuan gigafactory experience, operational since 2024 and having shipped over 600,000 cells.
Site advantages
Dunkirk was selected for its northern European logistics hub position, multimodal connectivity and an investment‑ready environment. The plant will have direct access to carbon‑free energy via proximity to the Gravelines nuclear power plant, with RTE acting as co‑project manager for the high‑voltage connection. The port and local authorities are positioned to support expansion and supply‑chain collaboration.
Roadmap and capacity
Key milestones include secured subsidies (2023), environmental approval and permit (2025), construction start (2026), Phase 1 mass production at 0.8 GWh (2028), ramp‑up (2029), full 4 GWh operation (2030) and 12 GWh by 2032, with long‑term potential to scale to 48 GWh.
