CellCube, founded in 2018, is one of the world's first and largest researchers, developers, manufacturers and distributors of vanadium redox flow batteries. It has installed vanadium flow batteries at over 130 sites globally.

The first CellCube batteries were installed in 2008 and with a decade of operational experience.

Customers all over the world have been operating the CellCube for 10 years and above. For more than 5 years now, the new power cell stacks have been running a continuous test with undisturbed operation meanwhile reaching over 20,000 cycles, which is equivalent to 28 years of daily cycling.

They offer three different CellCube models:

• FB 250/1000: 250kW/1000kWh
• FB 250/2000: 250kW/2000kWh
• FB 500/2000: 500kW/2000kWh

Their modular solution can be scaled up to MW size.

High efficiency Cellcube states their batteries have an efficiency of 94%, a very high efficiency for flow batteries technology.

Safety Vanadium Redox Flow Batteries are non-flammable and non-explosive.

Long cycle life Redox Flow batteries suffer no degradation, enabling a more than 8 cycles a day at 100%DoD and achieving 25 years lifetime with more than 15,000 cycles guaranteed.

With more than a decade of operational experience, the technology has been proven to deliver long lasting energy storage infrastructure for deployments in a wide range of climates and heavy load applications. This includes:

• Renewable baseload,
• Renewable energy integration,
• Peaker plant solutions,
• Reserve capacity and balancing market solutions,
• EV charging backbone,
• Micro grid and off grid storage,
• Several use cases at industrial plants and many more.
