Save your renewable energy and use it around the clock

Technology

The VisBlue Battery Solution does not use
conventional batteries, like other energy storage solutions, but is a self-developed battery, based on redox flow technology.

Scalability

With the VisBlue Battery Solution the electrical power and storage capacity can be scaled independently. This means that you can get a battery that is tailored exactly to your needs.

Eco-friendly

The VisBlue Battery Solution has separated major
operating components (tanks, electrolyte, pumps, electrode stack etc.), that are either recyclable or reusable in different ways.

The VisBlue Battery is an energy storage solution built around a unique vanadium redox flow battery

The VisBlue Battery Solution enables a higher utilisation rate of energy generated from your renewable energy sources and store it for use around the clock.

 

How does it work?

• A vanadium redox flow battery (VRFB) has two separate tanks, one containing a positive electrolyte and one negative electrolyte. Both electrolytes consist of the element vanadium dissolved in sulphuric acid, with the vanadium occurring in different oxidation states (valences).

 

• The battery has a number of battery cells as well. Each of these cells is divided into two chambers separated by a membrane, through which the ions can pass. In each chamber there is a positive or a negative electrode. The two electrolytes are pumped through the cells on their side of the membranes.

 

• The current from the solar panels is fed down into the cells’ electrodes, where it moves electrons from the positive to the negative electrolyte, charging the battery as the liquid flows back into the tank. During discharge, this process is then reversed.
