Optimisation of renewable energy

Store excess energy from solar and wind - and use it when it creates the most value.

Store excess energy from solar and wind - and use it when it creates the most value.

Why is energy storage key to the green transition?

Renewable energy from solar and wind is a cornerstone of the green transition, but without storage, a large share of the generated energy is lost. When production exceeds consumption, excess energy is fed into the grid at a low price only to be bought back at a higher cost when demand rises. With a flow battery from VisBlue, you can store the energy and use it when it makes the most sense. This leads to higher utilisation of your solar installations and a significant reduction in CO₂ emissions.

How flow batteries optimize renewable energy use

A flow battery stores energy in liquid electrolytes, allowing both power and capacity to be tailored to your needs. The technology is water-based and cannot catch fire, making it ideal for installation in buildings such as schools, care homes, sports facilities, and industrial sites. The system can be integrated into existing energy systems and combined with solar panels, heat pumps, and EV chargers. The result is a flexible solution that ensures maximum value from your investment in renewable energy.

Financial and environmental benefits

With renewable energy optimisation, you achieve both financial and environmental benefits. You reduce your dependence on the grid, lower your electricity costs, and protect yourself against fluctuations in energy prices. At the same time, you can document your climate efforts with concrete figures on CO₂ reduction and energy savings valuable for ESG reporting and sustainability communication. With a lifespan of more than 20 years and up to 20,000 cycles, VisBlue’s flow batteries are a long-term investment that supports both operational reliability and sustainability.
