VoltStorage – leading company for lithium-free battery storage
VoltStorage is the leading technology company for stationary flow batteries. With its international research and development team and the largest fleet of operating flow batteries in the world, VoltStorage has a wealth of accumulated in-depth expertise and experience.
broad battery technology expertise
World’s largest operating Flow Battery fleet
Since the market launch of our residential flow battery system in 2019, we have constantly increased the number of installed systems. Meanwhile, we have the largest fleet of operating flow batteries in the world. The collected data and experience is providing us a highly valuable basis for the continuing development of new pioneering battery solutions beyond lithium.
current technology project
Together with our international research and development team, we are working on pioneering battery storage solutions beyond lithium – the “Next Generation Batteries”. In order to realize our goal of resource-saving, cost-efficient and climate-friendly batteries for various stationary applications, we are currently working on a wide range of technology projects:
Iron salt battery long-term validation
Together with our partnering university, validation tests were successfully carried out to verify the enormous potential of the revolutionary Iron Salt battery technology. The results show a long-term stability without capacity and power losses at an efficiency of up to 78%.
Our next step is the confirmation of the results over time, based on a larger system configuration. This will allow us to further advance material and component selection and system development for commercial and industrial applications.
Flow battery for commercial applications
Following the successful launch of our home storage solution based on the vanadium redox flow battery technology, we are already working on the next “Next Generation Battery”: A VoltStorage battery storage system for commercial applications – resource-saving, climate-friendly and safe.
We want to give commercial businesses and farms the opportunity to rely on resource-saving battery technologies. For 100% renewable energy around the clock.
Next generation: flow battery cell stack
With our patented flow battery cell design, we were the first company in the world to succeed in developing a battery cell stack for flow batteries that can be manufactured automatically and thus produced in high numbers. But we are not standing still and are already working on the next generation of flow battery cell stacks.
The experience of developing, building and operating our flow battery fleet and the analysis of more than 1,000 components and materials is enabling us to develop a new and perfected flow battery cell design. This sets the course for the successful development of our “Next Generation Batteries”.
