Gigafactory Map — All Battery and Electrolyzer Factories in France

Overview

France is building one of the most concentrated and diverse gigafactory clusters in Europe, with multiple battery cell manufacturing facilities, electrolyzer plants, and associated supply chain infrastructure concentrated primarily in northern France’s Hauts-de-France region. This gigafactory map and data page tracks every significant large-scale clean energy manufacturing facility in France, providing comprehensive location, capacity, investment, and status data for the battery and hydrogen electrolyzer manufacturing landscape.

The term “gigafactory” — originally used to describe Tesla’s large-scale battery factories — has become shorthand for any large-scale, capital-intensive clean energy manufacturing facility. This page tracks both battery gigafactories (cell manufacturing at GWh scale) and electrolyzer gigafactories (MW to GW scale hydrogen electrolysis equipment manufacturing), France 2030’s two primary large-scale clean energy manufacturing categories.

Key Data and Figures

Battery Gigafactories in France (Complete Tracker)

GWh = Gigawatt-hours of annual battery cell production capacity. 1 GWh = sufficient batteries for approximately 10,000-15,000 battery electric vehicles (depending on battery pack size).

Geographic Clustering: Why Dunkirk?

The concentration of battery gigafactories in Dunkirk and the surrounding Hauts-de-France region is not coincidental. Five factors have made Dunkirk France’s primary battery manufacturing location:

1. Port infrastructure: Dunkirk is France’s third-largest port, capable of handling the large-format cathode active material and lithium compound imports that are currently unavoidable supply chain dependencies. Container handling, customs infrastructure, and warehousing capacity are prerequisites for gigafactory supply chain management.

2. Renewable + nuclear electricity grid connection: Dunkirk has access to high-capacity electricity grid connections, essential for gigafactories that consume 100-500 MW continuously in production. France’s northern coast is connected to planned North Sea offshore wind (Dunkirk’s offshore wind zone) and via the national grid to France’s nuclear baseload.

3. Land availability: Former industrial sites in the Dunkirk industrial zone provide large (50-200 hectare) flat, brownfield land parcels that can accommodate gigafactory footprints without agricultural land conversion — reducing environmental authorization complexity and community opposition.

4. Workforce heritage: The Hauts-de-France workforce has deep experience in industrial manufacturing (steel, chemicals, glass), with transferable skills in process control, quality management, and maintenance that battery manufacturing requires. Unlike greenfield industrial locations, Dunkirk’s workforce doesn’t need to build industrial culture from scratch.

5. Proximity to EV production: Renault’s Douai plant (Mégane E-Tech), Stellantis’ Valenciennes operation, and Toyota’s Onnaing facility are all within 100 kilometers — minimizing just-in-time supply logistics for the battery-to-vehicle integration that is critical to automotive supply chain competitiveness.

Battery Capacity Comparison: France vs. European Peers

France 2030’s battery manufacturing ambition places France in direct competition with Germany, Hungary, Poland, Sweden, and Spain for European battery supply chain leadership:

France’s 107 GWh under-construction capacity (as of Q1 2026) is Europe’s largest single country pipeline, though operational capacity (13 GWh) lags Germany and Hungary.

Supply Chain Facilities Supporting the Battery Cluster

The gigafactories themselves are the visible pinnacle of a supply chain that extends to materials processing, component manufacturing, and recycling. France 2030 has also invested in this supply chain:

Methodology and Sources

Gigafactory data is compiled from:

• Company press releases and investor presentations for capacity, timeline, and investment announcements
• Environmental authorization filings (ICPE authorizations published by local préfectures) for exact site specifications
• Local government economic development agencies (CCI Hauts-de-France, ADUS Dunkirk Urban Agency) for site-specific data
• IndustriAll Europe battery manufacturing tracker (trade union database of European battery investments)
• Benchmark Mineral Intelligence and BloombergNEF global gigafactory trackers (cross-referenced with French data)
• Satellite imagery cross-referencing (Planet Labs, Sentinel-2) for construction progress verification

Capacity figures are as announced by companies; actual installed capacity may vary as production ramps. GWh figures represent nameplate annual capacity at full production, which typically takes 18-24 months to achieve after commissioning.

Key Insights

• France has Europe’s largest under-construction battery pipeline: at 94 GWh under construction (Q1 2026), France leads Europe in committed but not yet operational battery capacity — a leading indicator of future competitive position.
• Technology diversity is a strategic strength: ACC’s NMC pouch cells, Verkor’s cylindrical cells, and ProLogium’s semi-solid-state represent three different technology vectors — reducing France’s exposure to any single chemistry becoming obsolete.
• Electrolyzer manufacturing is underdeveloped relative to production ambitions: France’s electrolyzer manufacturing capacity (600+ MW/year combined) is insufficient to support the 6.5 GW electrolyzer deployment target for 2030, indicating significant import dependency from German, Danish, and British electrolyzer suppliers will persist.
• Battery recycling infrastructure is ahead of the curve: France’s three operational battery recycling facilities (Eramet, Suez/Renault, Veolia) position France to capture the secondary materials value chain as first-generation EV batteries reach end-of-life in the late 2020s.
• The Dunkirk battery cluster creates a virtuous agglomeration: as ACC, Verkor, ProLogium, and supply chain companies all locate in the same corridor, labor market depth, supplier proximity, and shared infrastructure investment create compounding competitive advantages that will be difficult for later-entering competitor locations to replicate.

How to Use This Data

For supply chain companies: The gigafactory pipeline identifies current and future procurement requirements at scale. ACC (operational) is actively procuring; Verkor (construction) is procuring installation equipment; ProLogium (pre-construction) is in early supplier selection. Engineering, procurement, and construction companies should map their capabilities against each facility’s specific technology requirements.

For investors: The capacity timeline (operational → under construction → planned) provides the basis for modeling French battery manufacturing revenue growth through 2030. Combined operational capacity by 2028-2030 of 100+ GWh would make France one of Europe’s 2-3 largest battery manufacturing nations — a structural market position change with implications for automotive supply chain security across the continent.
