SKELETON TECHNOLOGIES GMBH

Their core work

Skeleton Technologies is a German deep-tech SME that develops and manufactures high-power energy storage devices, specifically ultracapacitors and hybrid capacitor cells based on advanced electrode materials. Their H2020 work centres on metal-oxide capacitor chemistries that push the energy density of supercapacitors closer to battery territory, with applications in low-carbon mobility and grid stabilisation. As an Innovation Action coordinator with a €2.5M EC contribution for X-CAP, they operate at industrial pilot-line scale rather than pure research. A smaller participation in a bio-based materials project shows they also contribute capacitor/electrode know-how to cross-sector manufacturing consortia.

What they specialise in

How they've shifted over time

Their H2020 trajectory starts with pure-play energy-storage hardware: the 2020 X-CAP Innovation Action concentrated on metal-oxide capacitors for low-carbon mobility. From 2021 they widened their footprint by joining INN-PRESSME, a bio-based nano-materials and packaging ecosystem, which brought keywords like biomaterials, pilot lines, digitalisation and eco-design into their portfolio. The move suggests a small but deliberate push from a narrow product focus toward cross-sector manufacturing and sustainable-materials networks, though energy storage remains the commercial core.

They appear to be complementing their capacitor product line with participation in broader sustainable-materials and digitalised pilot-line consortia, which opens the door to joint work beyond pure energy storage.

How they like to work

They lead where the topic is central to their product — coordinating the X-CAP Innovation Action — and join as a smaller technical participant (€210K) where the consortium is outside their core, as in INN-PRESSME. With 38 unique partners across 11 countries in just two projects, they sit in fairly broad consortia rather than tight repeat-partner circles. Expect them to be pragmatic: ready to drive a project when the IP fit is clear, and willing to contribute a specialist slot otherwise.

38 distinct consortium partners spanning 11 European countries across just two projects, reflecting the wide industrial reach typical of Innovation Actions and pilot-line projects. The base in Grossrohrsdorf (Saxony) anchors them in the German manufacturing belt.

What sets them apart

Skeleton Technologies is one of the few European SMEs that actually manufactures high-power capacitor cells at industrial scale rather than just researching electrode chemistry on the bench. Their H2020 profile reflects that: they coordinate when their metal-oxide capacitor IP is at the centre, and they bring hardware-manufacturing credibility that most materials-science partners cannot. For a consortium needing an industrial energy-storage partner based in Germany, they are a natural lead.

Highlights from their portfolio

• X-CAP
  Their flagship H2020 action — coordinator role, €2.5M EC contribution, and a direct match to their core metal-oxide capacitor product line.
• INN-PRESSME
  Unusual sector jump into plant-based nano-biomaterials and packaging, signalling willingness to contribute capacitor/electrode know-how to adjacent manufacturing ecosystems.
