Skeleton Technologies has officially opened its €220 million SuperFactory in Markranstädt, near Leipzig.
The facility is already delivering to Siemens, General Electric, and Hitachi Energy for European electrical grids, and to major US hyperscalers for AI infrastructure.
With a fully European value chain, Skeleton’s supercapacitors use no lithium, cobalt, manganese, or other critical raw materials, and are based on the company’s patented Curved Graphene material.
Skeleton Technologies’ CEO Taavi Madiberk said: “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.”
The opening of this factory helps support Europe’s electrical grids which are already under strain due to the rising share of renewable energy. The combination of fast-growing AI data centre demand and accelerating renewable deployment is creating a perfect storm, pushing grids to their limits and making fast-response technologies such as supercapacitors essential for energy security.
“A vital player in the European electrical grid and AI infrastructure ecosystem, Siemens continues to support Skeleton in the roles of investor, supplier as well as a potential go-to-market partner as they seek to address growing demand in the region,” commented Steffen Grosse, CEO Equity Finance at Siemens Financial Services.
Opening the Leipzig supercapacitor facility follows the recent opening of the company’s SuperBattery facility in Varkaus, Finland. The Leipzig SuperFactory will create 420 jobs in Saxony and is designed for an annual output of up to 12 million cells. Leveraging Siemens Xcelerator, a curated portfolio of services, software, and IoT-enabled hardware from Siemens, the new plant reinforces Europe’s advanced industrial base.
