ProLogium Technology has officially broken ground on its European gigafactory in Dunkirk, France, marking a major step toward large-scale production of next-generation solid-state batteries in Europe.
The facility will manufacture ProLogium’s fourth-generation all-inorganic solid-state lithium ceramic batteries, a technology designed to deliver improved safety, higher energy density, faster charging, and better low-temperature performance compared to conventional lithium-ion batteries.
The project represents ProLogium’s first production site outside Taiwan and reinforces Europe’s push to build a resilient, sovereign EV battery supply chain.
French President Emmanuel Macron highlighted the strategic importance of the investment, positioning the project as both an economic and climate milestone for France and the European Union.
The Dunkirk gigafactory supports Europe’s broader objective of reducing reliance on imported battery technologies while accelerating electrification and industrial decarbonization.
For EV manufacturers and Tier 1 markets increasingly focused on local sourcing, supply-chain resilience, and carbon footprint reduction, the plant adds critical production capacity within Europe.
ProLogium selected Dunkirk due to its strategic location as a northern European logistics hub and its access to competitive, low-carbon electricity.
The site will benefit from:
– Direct proximity to the Gravelines nuclear power plant, ensuring stable carbon-free energy supply
– Multimodal transport links including maritime, rail, road, and inland waterways
– Support from French grid operator RTE for high-voltage infrastructure
– A rapidly expanding clean industrial cluster focused on reindustrialization
This infrastructure enables lower transportation emissions, faster distribution across European automotive markets, and long-term scalability.
ProLogium’s Dunkirk facility will be built around its “Superfluidized All-Inorganic Solid-State Lithium Ceramic Battery” mass-production platform.
The goal is to move solid-state technology from advanced R&D to consistent, high-volume output.
ProLogium’s Taoyuan gigafactory in Taiwan, operational since 2024, has already produced more than 600,000 cells—providing industrial validation ahead of European scale-up.
Production Timeline and Capacity Targets
The Dunkirk roadmap outlines a phased ramp-up:
– 2023 – French government subsidies secured
– 2025 – Environmental approvals and construction permits obtained
– 2026 – Groundbreaking and start of construction
– 2028 – Fab 1 Phase 1 completed; Gen4 production begins (0.8 GWh)
– 2029 – Capacity ramp-up
– 2030 – Fab 1 Phase 2 completed; 4 GWh total capacity
– 2032 – Full Phase 2 completion; total capacity reaches 12 GWh
The site also includes reserved land for long-term expansion, with potential scaling up to 48 GWh, positioning Dunkirk as a future cornerstone of Europe’s next-generation battery production.
Solid-state batteries are widely seen as a breakthrough technology for electric vehicles. Compared to today’s lithium-ion cells, ProLogium’s ceramic-based architecture aims to deliver higher safety margins, increased driving range and faster charging times.
Europe’s Next Battery Hub?
With multiple gigafactory projects underway across France and Germany, Dunkirk is emerging as one of Europe’s most important battery clusters.
ProLogium’s investment aligns with France’s reindustrialization strategy and the EU’s long-term energy transition goals. For automakers operating in Europe — and for global EV brands supplying Tier 1 markets — localized solid-state production could become a competitive differentiator in the coming decade.
As construction begins, the focus now shifts to execution and scale — a critical test for solid-state batteries transitioning from promise to mass production reality.
