CellCube

We’re back from the U.S. — and made a powerful stop at TEVCON 2025 — and wow, what an event! Massive shoutout to the organizers Tom Holm and everyone who came by to connect. CellCube showed up strong, proving how our vanadium flow batteries take energy resilience to the next level — powering mission-critical infrastructure with smart, secure microgrids.

CellCube geführt von Christoph Stelzer, Patrick Halwax und Fabio Denner mit Sitz in Wiener Neudorf ist ein Hersteller nachhaltiger Langzeit-Energiespeicher auf Basis von Vanadium-Redox-Flow-Technologie. In seiner langen Geschichte als Spin-off gestartet agierte das Unternehmen unter fünf verschiedenen Namen und war bisher erfolgreich in den USA tätig. Nun legt man den Fokus auf Europa. "CellCube-Batterien haben eine Lebensdauer von über 25 Jahren und können unbegrenzt oft geladen und entladen werden, ohne an Kapazität zu verlieren." - Patrick Halwax.

✨ Exciting news! Quino Energy has been awarded a $2.6M grant from the U.S. Department of Energy (DOE) (#AMMTO) 🎉, and CellCube’s power block will play a key role in their 2 MWh demonstration unit ⚡🔋. 🌍 By combining our technology with their Made in USA 🇺🇸 organic electrolyte in carbon steel tanks, we’re showcasing the future of sustainable energy storage 🚀. #CellCube #EnergyStorage #DOE #Quino
