CellCube - energy storage for demand-charge management and lower energy costs.

Combine peak shaving and emergency power supply through the reliable vanadium redox flow technology. The energy storage system CellCube stores energy for when it is most needed. What is more, it is capable of scaling to multi hour and multi megawatt size.

CellCube storage systems solve the problem of energy storage and peak demand charges. Whether in combination with PV systems, wind generation, diesel or biogas generators, or operated in parallel to the public grid - the CellCube meets your demand needs, enables renewable energy integration on the grid, provides distribution deferral and fulfils resiliency needs.

The system distinguishes itself from other technologies through its high safety, unlimited cycling, storage stability and very fast reaction times. It has the highest residual value amongst battery powered energy storage systems.

Its TÜV Süd NRTL (Nationally Recognized Testing Laboratory) and ISO certification make it suitable for North American markets where the product accreditation is a pre-requisite for permitting and insurance. It is also Green Data compatible and can help businesses conserve energy and better manage their electricity costs.

CellCube is an individual energy storage system, which adapts to every requirement. The system power output and capacity is scalable from the kilowatt range to the megawatt range without a problem. The modular and flexible structure of the system allows varied application options conceptualized according to requirements, depending on customer preferences.
The CellCube has proven itself more than 100 applications worldwide (e.g. Eon/ Pellworm, Volkswagen, agriculture companies in Germany and the Netherlands, Telecom networks in South Africa etc.).
