SKELETON TECHNOLOGIES OU

Their core work

Skeleton Technologies develops and manufactures ultracapacitors (supercapacitors) based on carbide-derived carbon (CDC) technology. They progressed from proving CDC production feasibility to scaling up manufacturing for high-performance energy storage devices. More recently, they have expanded into polymer-based energy harvesting and storage systems, integrating piezoelectric and thermoelectric generators with supercapacitor storage for IoT applications.

What they specialise in

How they've shifted over time

Skeleton Technologies started in 2014 with a clear single focus: developing and scaling carbide-derived carbon (CDC) production for supercapacitors, moving from feasibility study (SKLCarbon) to full industrial scale-up (SKLCarbonP2). By 2020, they broadened into energy harvesting systems through InComEss, contributing their supercapacitor expertise to a larger consortium working on piezoelectric and thermoelectric energy scavenging integrated with IoT. This shift suggests a company that has matured its core product and is now exploring adjacent applications where supercapacitors serve as the storage component in self-powered systems.

Skeleton Technologies is moving from being a pure supercapacitor manufacturer toward becoming a component supplier for integrated energy harvesting systems, particularly for IoT and self-powered devices.

How they like to work

Skeleton Technologies primarily leads their own projects — they coordinated 2 of 3 H2020 projects, both through SME Instrument funding (Phase 1 and Phase 2), which are single-company grants focused on business scale-up. Their one consortium participation (InComEss, as partner in a larger RIA project) shows they can also contribute specialist expertise to multi-partner research efforts. With 18 unique partners across 9 countries, their network is moderate but diverse for a company of their size.

They have collaborated with 18 unique partners across 9 countries, mostly through the InComEss consortium. Based in Estonia, their partnerships span a broad European geography rather than clustering in any single region.

What sets them apart

Skeleton Technologies is one of the few European SMEs with proprietary carbide-derived carbon technology for ultracapacitors — a niche with very few competitors globally. Their progression from SME Instrument Phase 1 to Phase 2 (with EUR 2.49M) signals that EU reviewers validated both the technology and their commercialization plan. For consortium builders, they bring a rare combination: a deep-tech energy storage SME with manufacturing capability and a proven track record of scaling from lab to production.

Highlights from their portfolio

• SKLCarbonP2
  Their largest project (EUR 2.49M via SME Instrument Phase 2) focused on industrializing CDC supercapacitor production — a strong signal of commercial readiness.
• InComEss
  A multi-partner RIA project (2020-2024) where Skeleton contributed supercapacitor expertise to an innovative polymer-based energy harvesting system for IoT, showing their expansion beyond core manufacturing.
