Skeleton Technologies has inaugurated its $240 million (€220m) Leipzig SuperFactory.
The site, located in Markranstädt, near Leipzig in Germany, is already supplying Siemens, General Electric and Hitachi Energy for grid applications, alongside major US hyperscalers for AI demand.
The factory’s supercapacitors are built on Skeleton’s patented Curved Graphene material, avoiding lithium, cobalt, manganese and other critical raw materials. With a fully European value chain, the company positions itself as a strategic player in stabilising grids and supporting AI growth.
In 2026, US hyperscalers are forecast to invest $330 billion in AI infrastructure, compared with Europe’s modest $10 billion. The continent faces two pressing challenges: rising electricity bills as AI data centres consume more power, and limited European manufacturing share in AI infrastructure.
“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,” said Skeleton Technologies’ CEO Taavi Madiberk. “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 Leipzig SuperFactory will create 420 jobs in Saxony, producing up to 12 million cells annually. Following the recent SuperBattery launch in Finland, the plant leverages Siemens Xcelerator to strengthen Europe’s industrial base.
