CellCube's Corporate Mission... 

To be a fully integrated producer of vanadium, vanadium electrolytes and vanadium redox flow batteries for the energy storage industry.

Until recently, storage of electricity for a later date was largely limited to small electrical-chemical batteries, lead acid, nickel-cadmium. 

Current consumer technology is dependent upon batteries for cell phones, laptop computers, electric cars. Individually these require relatively small amounts of energy storage. Now it is possible to store vast quantities of electricity that can be used at a later time. Energy storage systems are now built to store mega-watts or giga-watts of energy for grid or off-grid usage. There are a variety of different types of batteries deployed - lithium ion and now vanadium redox flow batteries. 

Lithium ion is typically used for short-term storage and vanadium redox flow batteries are leading the way for large-scale stationary energy storage in grid and off-grid applications.


Vanadium Redox Flow Batteries are the Most Advanced Stationary Storage Batteries Today

Originally produced by NASA in the 1970s, the vanadium redox flow battery (VRFB) has clear advantages compared to other systems and technologies. It can offer almost unlimited energy capacity simply by scaling up the electrolyte storage tanks. Housed in a 40 ft. container, the VRFB van be dropped off anywhere in the world withstanding any climate condition. 

It is capable of 100% discharge without having to worry about dropping below a certain charge level. In fact, it can be left completely discharged for long periods with no ill effects. This also makes maintenance much easier compared to other batteries. Moreover this storage system offers daily charge and discharge cycles according to the load requirements and is not limited to a maximum number of cycles as other technologies.

The life cycle is up to 20 years making it the ideal combination with long-term renewable energy projects. The VRFB itself can be monitored 24/7 and even be operated by remote control. In the event of interruptions the technology provider can receive a service alert and react within minutes to secure a continuous power supply. Because of these unique properties, VRFBs can considerably reduce the cost of storage.

The CellCube is a Complete Power System 

It is a turnkey on-demand, plug-in-play grid ready solution to deliver power when, how and where it is needed. The CellCube allows for a clean emission-free and fast energy supply at all times. A stable power supply, for example in combination with renewable energy sources, is ensured at all times and in every climate zone. The use of vanadium salts increases the safety and battery life. It is thus non-flammable and non-explosive and is not subject to any loss of reactive material. The CellCube allows a practically unlimited cyclization and a depth-discharging capacity of 100%.

With its simple and independent scalability in power output and storage capacity, the CellCube is ideally suited for individual industrial applications, to smoothen load peaks, for e-mobility solutions, for off-grid applications and for micro-grid power supply in regions without a stable power grid.



Stand-alone microgrid and grid as backup

Unstable grids fail on a weekly basis and may leave you without power for several hours. Here you use the CellCube to build your own stand-alone microgrid and connect to the grid only when needed (ex. during low solar output or a low charge level in the CellCube). As a result, you avoid power outages from the utility grid.

Grid parallel wITH stand-alone microgrid 

This topology adds the possibility to establish a stand-alone microgrid when the utility grid fails. Ideal for backup power (non UPS.)

Stand-alone microgram (island or off-grid)

CellCube automatically charges and discharges as needed in order to build and maintain a stable microgram voltage and frequency. Excess renewable energy is stored and later fed into the microgrid when needed. It's even possible to signal a diesel generator for additional power charging the CellCube. This system design is common for distant communities and rural electrification. 

Grid parallel (i.e. grid connected)

In a grid parallel topology the CellCube is typically used to increase self-consumption of renewables (PV, wind, etc.), increase energy autonomy, and for demand site management.
