New European facility delivers one gigawatt of high-power capacity for AI infrastructure.
InnoEnergy warmly welcomes the inauguration of Skeleton Technologies’ new SuperBattery factory in Varkaus, Finland. This marks a significant milestone for the company’s scale-up and for Europe’s ability to supply high-power storage solutions essential for AI data centres and other demanding applications.
With a total of €50 million invested in the facility, it becomes Europe’s first production site dedicated to high-power batteries for AI infrastructure and the world’s first to industrialise backup power systems for mission-critical computing and emerging technologies such as nuclear fusion.
Supporting Europe’s high-power battery capability
The new Varkaus plant represents an important step toward Europe’s strategic energy resilience. By localising advanced battery production in Finland, Skeleton helps reinforce European manufacturing independence at a time when demand for high-power storage is accelerating across AI infrastructure, mobility, defence, and grid stability.
“AI, mobility, and the grid of the future all require extreme power, reliability, and sustainability,” said Taavi Madiberk, CEO and co-founder of Skeleton Technologies. “Our Varkaus factory is a cornerstone for sovereign European AI infrastructure […] ensuring that the digital revolution is powered responsibly and independently.”
The facility will provide one gigawatt of high-power battery capacity annually, directly supporting Europe’s rapidly expanding AI infrastructure.
Revitalising a historic battery innovation site
The Varkaus factory sits on the former site of European Batteries Oy, a pioneer in Europe’s battery industry and the first producer of LFP batteries on the continent. Skeleton’s investment brings new life to a location long associated with technological progress in Finland.
“I have been following Skeleton Technologies since its creation in 2009. Their technical expertise is outstanding, and the opening of the new Varkaus factory represents a major boost for Finland’s innovative battery value chain,” noted Lassi Noponen, Director General of Business Finland.
The factory, currently employing more than 65 people, will increase Skeleton’s workforce in Finland to over 200 employees by 2029, reinforcing the country’s position as a centre for advanced manufacturing and clean-tech development.
Advanced materials for high-demand applications
Skeleton’s SuperBattery technology integrates NBXCELER™ niobium oxide materials supplied by long-term partner CBMM, a global leader in niobium production. Niobium improves battery durability, safety and performance – crucial attributes for high-power, high-duty applications such as AI data centres and industrial operations.
“Niobium plays a key role in shaping a more sustainable future,” said Ricardo Lima, CEO of CBMM. “Our partnership with Skeleton demonstrates how Niobium can make AI infrastructure safer, longer lasting, and more efficient.”
A long-standing collaboration reaching a new milestone
InnoEnergy has accompanied Skeleton Technologies for more than a decade as the company progressed from early-stage innovation to the industrial achievements now visible in Varkaus. The opening of the SuperBattery factory reaffirms the importance of sustained innovation, strategic partnerships, and industrial ambition.
“Today is an important moment for one of Europe’s most forward-looking energy-storage companies,” said Lowina Lundström, CEO at InnoEnergy Scandinavia. “The Varkaus facility shows how determined industrial development can advance Europe’s position in high-power technologies and bring strategic solutions to market at scale.”
