Advancing Europe’s high-power energy storage industrial base to support grid stability and AI infrastructure
InnoEnergy welcomes the opening of Skeleton Technologies’ SuperFactory in Markranstädt, near Leipzig – an important milestone in the company’s continued industrial expansion and a timely contribution to strengthening Europe’s ability to implement the fast-response, high-power technologies needed to support its electrical grids and emerging AI infrastructure.
Designed for an annual output of up to 12 million cells, the facility is already supplying Siemens, General Electric, and Hitachi Energy for European grid applications, as well as major US hyperscalers for AI data centres, and represents an investment of €220 million. Built on a fully European value chain and using Skeleton’s patented Curved Graphene material, the company’s supercapacitors avoid lithium, cobalt, manganese, and other critical raw materials.
Addressing rising energy and AI challenges
“Skeleton’s Leipzig factory addresses both challenges. The plant manufactures our latest graphene-based supercapacitors, used in GrapheneGPU™, enabling AI data centres to cut total electricity consumption by 44% by smoothing power peaks and reducing stress on the electrical grid. At the same time, it keeps a core part of the value chain in Europe. By eliminating power peaks and overheating, GrapheneGPU™ unlocks 40% more computing power from the same investment in other GPUs,” said Taavi Madiberk, CEO and co-founder of Skeleton Technologies.
Europe’s electricity networks are already under strain from higher shares of renewable energy. Combined with rapid growth in AI-driven electricity demand, fast-response technologies such as supercapacitors are becoming essential. The 2025 Iberian blackout highlighted grid vulnerabilities, and the European Commission estimates that €584 billion in investment will be required by 2030 to modernise European networks.
“When it comes to the electrical grid, our mission is simple: keep the lights on in Europe,” Madiberk added. “Skeleton’s systems are already used by German transmission operators as a last line of defence, a real safety belt for a grid increasingly powered by renewables.”
Building on recent industrial momentum
The inauguration of the Leipzig SuperFactory follows the recent opening of Skeleton’s SuperBattery plant in Varkaus, Finland, further expanding the company’s European manufacturing footprint. The new facility will create 420 jobs in Saxony and leverages Siemens Xcelerator to integrate advanced automation and digitalisation technologies.
“This new milestone demonstrates Europe’s ability to scale breakthrough technologies with global impact,” said Lowina Lundström, CEO at InnoEnergy Scandinavia. “Skeleton is the only fully integrated European company in high-power energy storage, covering the entire value chain from raw materials to cells, modules, systems, and software.” With more than 70 patent families and a strong deep-tech foundation, the company continues to advance Europe’s high-power capabilities. “Skeleton’s new Leipzig facility strengthens the continent’s position in a field where both grid stability and AI infrastructure depend on rapid, reliable, and sustainable innovation. We are proud to have accompanied Skeleton’s rise from early innovation to industrialisation,” added Lowina.
