To achieve Denmark’s climate targets, we must use energy from solar and wind efficiently and flexibly. With VisBlue’s flow batteries, you can store excess energy and use it when demand is highest, when the sun isn’t shining, the wind isn’t blowing, or electricity prices are high.
With VisBlue’s flow batteries, you can store excess energy and use it when demand is highest, when the sun isn’t shining, the wind isn’t blowing, or electricity prices are high.
We want to make the green transition a secure, long-term and scalable investment with our Danish-developed battery solution. Whether it is a municipality, housing association, company or advisor, we help find a solution that matches the specific needs. Below, we present the energy solutions that VisBlue’s flow battery can provide:
Batteries are a key tool for a successful green transition. They help ensure that renewable energy is available when it’s needed. Benefiting both the environment and your finances.
We want to be green.
For this reason, we use the proven Vanadium Redox Flow (VRF) technology - a water-based technology consisting of up to 85% water. This provides a key safety advantage, as the battery cannot catch fire.
The technology also enables the battery to operate at 100% capacity throughout its 20+ year lifespan. After that, the vanadium liquid can be regenerated - in fact, up to 99% of the battery is recyclable.
As a result, the technology stands out with clear, tangible advantages compared to conventional battery types.
Renosyd meets demand for green energy by combining solar power with energy storage from VisBlue. The solution ensures self-generated green electricity, improves cost efficiency, and relieves pressure on the grid. They benefit from a battery that stands out as responsible, safe, durable, and Danish.

Below you’ll find the most frequently asked questions. You’re also always welcome to give us a call.
view the full FAQYes, the majority of the components in our battery solution are recyclable.
Up to 99%, to be precise.
The core of VisBlue’s battery solution consists of a stack and two tanks. The tanks are made from conventional plastic and are recyclable, and all components of the stack, except for the membrane, can also be recycled.
A VisBlue battery solution includes the following key components: vanadium electrolytes, tanks, pumps, and an electrode stack. The system is designed so that these components can be easily removed and reused.
Our battery solution has a lifespan of over 20 years.
In theory, the battery solution has an unlimited lifespan, but in practice, this is not quite the case.
The components of our battery solution, such as the plastic tanks, hydraulics, and mechanical systems, also have long lifespans.
Cost savings and lower electricity bills
At VisBlue, we contribute to a greener world.
Our batteries provide savings from day one.
With a VisBlue battery, you can make much better use of the electricity generated by your renewable energy sources, reducing the need to purchase power from the grid and lowering your electricity bill.
We increase the utilisation of solar energy and build our batteries using recyclable materials.
Scalable
Whatever your needs, our battery solutions can be tailored to match the exact capacity required. Sustainability should also make financial sense.
Long lifespan
Our batteries have a long lifespan. Significantly longer than conventional battery types on the market.
They typically deliver between 10.000 and 20.000 cycles (a cycle being one full charge and discharge), equating to an approximate lifespan of 20+ years.
Saftey
Our batteries are safe to install in densely populated areas. In fact, they are safe to install almost anywhere. They consist of approximately 80% water, 10-15% sulfuric acid, and 5-10% vanadium. Due to the high water content, they cannot catch fire or explode.
99% recyclable
Our batteries are up to 99% recyclable.
They are made from components that are easy to recycle, and the system is designed to be easily disassembled and reused.
Greener energy
At VisBlue, we contribute to a greener world.
We increase the utilisation of solar energy and manufacture our batteries using recyclable materials. A VisBlue battery allows you to use more of the electricity generated by your renewable energy sources, reducing your reliance on grid electricity and lowering your energy costs. By reducing dependence on grid electricity, VisBlue customers are also less exposed to changes in tariffs, regulations, and politics affecting energy pricing and the export of surplus electricity.
A flow battery works by storing and releasing energy through an electrochemical process, where charged particles move between two liquids (electrolytes) stored in separate external tanks. The battery's unique design allows energy capacity and power to be scaled independently, distinguishing it from traditional batteries such as lithium-ion.
