R.Flo is a Ukrainian energy storage technology company developing innovative iron flow batteries (IFB) for commercial, industrial, and utility applications. Through their advanced battery design, which uses iron salts dissolved in liquid electrolytes, R.Flo provides efficient and sustainable energy storage solutions. The company’s technology addresses critical needs in renewable energy integration, offering extended storage duration while maintaining cost effectiveness. With a dedicated team of experts bringing 78 years of combined experience in research, development, and finance, R.Flo aims to reduce global carbon emissions by 50% through their sustainable energy storage solutions.
Battery Technology
R.Flo’s iron flow battery technology represents a significant advancement in energy storage systems. The batteries utilize iron salts in liquid electrolytes, creating a safe, non-toxic, and non-flammable energy storage solution. This technology delivers exceptional performance metrics, including over 40,000 charge-discharge cycles with minimal degradation of just 1% over 25 years.
The system operates efficiently across temperatures ranging from -20°C to +50°C without requiring air conditioning, making it adaptable to various environmental conditions. R.Flo’s batteries achieve project costs below 120€ per kWh, including connection expenses, resulting in up to 25% reduction in electricity costs for commercial and industrial users. For energy developers, the technology promises a 30% increase in internal rate of return.
A notable advantage of R.Flo’s battery design is its complete recyclability, with all components manufactured within the European Union. The use of abundant iron resources ensures a sustainable and reliable supply chain, avoiding dependencies on rare earth materials.
Recent Projects
As of early 2025, R.Flo has initiated a prototype project through the InnovateUkraine competition, supported by UK government funding. This project involves developing a 12.5 kW/75 kWh iron flow battery prototype, which will be connected to a rooftop PV system in Ukraine. The company is working in partnership with Ukrainian energy company KNESS and UK renewable energy company dpSun to implement this demonstration project.
