New technology for green energy storage

battery with solar cells

Sustainable battery solution for power storage

Storage of power stabilises operation costs, helps maintain the security of supply and indulges the rather wavering legislation.

A VisBlue battery enables you to use green power during the night, keep track of your consumption and purchase power when prices are low. The battery is sustainable, safe and scalable and has a life expectancy of more than 20 years.

What is the lifetime of a battery solution from VisBlue?

Our battery solutions have a lifespan of more than 20 years.

In theory, the lifespan of a battery solution that consists of vanadium electrolyte is infinite. Vanadium, in principle, never wears out because of a chemical reaction, as vanadium is also rechargeable.

The remaining components of our battery solutions also have a long lifespan, such as the plastic tanks, which store the vanadium electrolyte, that can last for decades, and the involved electronics, which are easily upgradable.

Is a battery solution from VisBlue scalable?

Yes, our battery solution is scalable and can be tailored to fit the needs of the customer.

This is possible, as we can both design and arrange the desired number of VisBlue units to meet the energy requirements of the customer. To determine the customer’s energy requirements, we begin with a specific calculation of exactly this, along with the expectations of the customer.

Our calculations are accomplished with the help of advanced simulation software, which we ourselves have developed for the occasion.

One of VisBlue’s strengths lies in our ability to calculate the exact needs, expectations, and requirements of our customers, so that they receive an optimal battery solution, that agrees with their initial wants and wishes.

What does a battery solution from VisBlue cost?

It is difficult to determine the exact price of our battery solution, as every single one of our battery solutions are different, in principle.

The VisBlue Battery Solution is custom made for the specific customer at hand, so as it meets whatever energy requirements the customer may have.

Please, feel free to contact us to see if we can tailor a solution that fits exactly your needs.

Is a battery solution from VisBlue recyclable?

Yes, the majority of the components in our battery solutions are recyclable.

99% to be exact.

The core of a VisBlue Battery Solution consists of the following major components: an electrolyte stack and two tanks, which are made of conventional plastic, and these are either recyclable or reusable. Furthermore, two metal plates hold the stack together, and these are also recyclable.

A battery solution from VisBlue consists of the following major operating components: vanadium electrolyte, tanks, pumps, and electrode stack. These components are separated and are therefore easy to remove and recycle separately.
