ProLogium Technology has broken ground on its first European gigafactory in Dunkirk, France, marking a significant milestone in the company’s global expansion and Europe’s push toward battery sovereignty. The facility will manufacture fourth-generation, all-inorganic solid-state lithium ceramic batteries, aimed at accelerating electrification and reinforcing the region’s industrial and technological independence.
The groundbreaking ceremony was attended by senior French government officials, regional leaders, and industry representatives. President Emmanuel Macron described the investment as a matter of national and European sovereignty. He said the project would create jobs in the Dunkirk region while supporting the decarbonization of the French economy and strengthening Europe’s strategic autonomy in battery production.
Vincent Yang, Founder and CEO of ProLogium, said the project marks a transition from innovation to industrial-scale execution. He emphasized that the company is bringing its proven mass-production platform from Taiwan to Europe, with clear milestones for start-of-production and ramp-up. He added that collaboration with local partners will be central to building a resilient, localized supply chain aligned with Europe’s energy transition goals.
French ministers echoed the strategic importance of the investment. Roland Lescure, Minister for the Economy, Finance, and Industrial, Energy and Digital Sovereignty, said the project represents a key milestone in positioning France as a leader in next-generation battery technologies. Officials highlighted the alignment of the gigafactory with France’s Green Industry Act and the France 2030 plan, which aim to accelerate low-carbon industrial development and strengthen domestic manufacturing capabilities.
The Dunkirk site will produce ProLogium’s Superfluidized All-Inorganic Solid-State Lithium Ceramic Batteries, designed to balance safety, performance, and scalability. The facility will establish a localized manufacturing ecosystem covering production, quality systems, and supply-chain coordination. The company will work with European partners to enhance supply resilience and accelerate battery localization.
Dunkirk was selected for its strategic position as a northern European logistics hub and its access to multimodal transport networks, including maritime, rail, inland waterways, and road links. The site also benefits from proximity to the Gravelines nuclear power plant, ensuring access to competitive, low-carbon electricity. Regional authorities view the project as a cornerstone of a growing “battery valley” in Hauts-de-France.
ProLogium’s roadmap outlines phased capacity expansion. Construction begins in 2026. Fab 1, Phase 1 is expected to be completed in 2028, initiating Gen4 mass production at 0.8 GWh. Capacity ramp-up is planned for 2029, with full operation at 4 GWh by 2030. By 2032, total capacity is projected to reach 12 GWh. The company has reserved additional land at Dunkirk Port, allowing long-term expansion potential up to 48 GWh, depending on market demand.
ProLogium is leveraging experience from its Taoyuan gigafactory in Taiwan, operational since 2024 and having delivered more than 750,000 cells. The Dunkirk project signals a broader effort to anchor advanced battery manufacturing in Europe while supporting electric vehicle performance improvements in range, safety, charging speed, and recyclability.
