The VisBlue battery increases the utilisation rate of power produced from renewable energy sources and allows you to use it around the clock.
You get plenty of advantages, when you use VisBlue's battery solution.
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
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.
