Last week, on 28 November 2025, Skeleton Technologies officially opened its new “SuperFactory” in Markranstädt, near Leipzig. This milestone marks a significant leap forward for Europe’s energy-storage infrastructure.
The new facility represents a total investment of €220 million and is projected to produce up to 12 million graphene-based supercapacitor cells per year.
These supercapacitors rely on Skeleton’s patented Curved Graphene material, bypassing critical raw materials such as lithium, cobalt, or manganese. That makes them a more sustainable and geopolitically resilient alternative to traditional battery technologies.
Because of this, the Leipzig plant plays a key role in strengthening European sovereignty over high-power energy storage, reducing dependency on volatile supply chains for critical raw materials.
The new SuperFactory is already supplying major energy infrastructure players such as Siemens, General Electric and Hitachi Energy for European power grids, and global hyperscalers for AI data-centre infrastructure.
According to Skeleton’s CEO Taavi Madiberk, the facility’s supercapacitors enable AI data centres to reduce their total electricity consumption by up to 44 %, by smoothing power peaks and reducing load on the electrical grid. At the same time, staying within a fully European value chain ensures that a significant portion of the added value remains on the continent, an important factor for industrial sovereignty and supply-chain resilience.
In a time when renewable energy growth and skyrocketing demand from AI-driven data-centre build-out put increasing strain on power grids, fast-response energy storage solutions such as supercapacitors become critical for grid stability and energy security.
The SuperFactory creates 420 new jobs in Saxony, contributing to local economic growth and reinforcing Germany’s – and Europe’s – position in high-tech manufacturing.
At the inauguration, dignitaries including the Estonian Prime Minister and regional political leaders underlined that this facility represents “the largest investment by an Estonian company in Germany”, and a strategic step toward making Europe a frontrunner in green technology and energy storage.
This move resonates with growing European efforts to build a sovereign, resource-secure supply chain for energy storage, a necessity in a world facing both climate challenges and supply-chain geopolitics.
As a long-standing partner and distributor in the field of ultracapacitors / supercapacitors, MSA Components views the opening of the Leipzig SuperFactory as a watershed moment. The increased production capacity, the sustainable material basis, and the broad applicability of the new supercapacitors open fresh opportunities, especially in industries requiring high-reliability storage solutions: defence, aerospace, grid infrastructure, AI data centres, mobility and industrial sectors.
MSA Components is eager to leverage this development, expanding its portfolio of high-power energy-storage solutions and offering customers access to next-generation, European-made, sustainable supercapacitor technologies.
