Scalable modules and adaptable systems, designed to last. Built on a responsible and intelligent technology to ensure maximum economic, social and environmental sustainability.
Flow batteries
With the VisFlow platform, you get a durable and scalable battery that is adapted to the unique needs of your company or institution. Recharge the battery with excess green energy from your renewable energy sources or buy cheap power from the grid when prices are low with SMARTflow spot price optimization. This creates balance, security and peace of mind in uncertain times.
Spot price Optimization
With SMARTflow, you get an intelligent battery that knows your consumption pattern and can predict the weather and prices in the electricity grid. And do you have solar cells, heat pumps, charging stations or other energy technologies, the battery will also incorporate these.
That way, you are always guaranteed the most optimal charging profile.
That is SMART.
You get plenty of advantages when you use VisBlue's battery solution for storing your green power. The technology offers a safe and more environmentally friendly battery solution that makes it possible to store more of the energy produced by the solar cells. The redox flow battery solution can scale power and capacity independently of each other.

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.
