energy storage

Save your renewable energy and use it around the clock

The VisBlue battery is a sustainable
energy storage solution that makes your electricity bill cheaper and greener

The VisBlue battery increases the utilisation rate of power produced from renewable energy sources and allows you to use it around the clock.

Let VisBlue help you increase the utilisation rate of your solar panels or wind turbine

VisBlues batteries are sustainable and make it possible for you to have a greener and more intelligent energy consumption - and most importantly, a cheaper one.*

*NB currently we do not make batteries for private households/smaller batteries due to size and price

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.
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.

How a flow battery works

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.

VisBlue has refined the flow technology and made it scalable,
making it usable in a variety of different contexts, e.g. industry,
housing associations/apartment complexes, and grid stabilisation.
