R.Flo’s iron flow battery technology utilizes iron salts dissolved in liquid electrolytes to provide a safe, non-toxic, non-flammable energy storage solution. The system delivers over 40,000 charge-discharge cycles with only 1% capacity degradation over 25 years, operates in temperatures from -20°C to +50°C without air conditioning, achieves project costs below €120/kWh including connection expenses, and supports fully recyclable components manufactured within the EU, leveraging abundant iron resources to avoid rare earth dependencies.
Currently developing a 12.5 kW/75 kWh iron flow battery prototype designed for rooftop PV integration, with scalability for commercial, industrial, and utility applications.
In 2025, R.Flo initiated a prototype project under the InnovateUkraine competition, funded by the UK government, to deploy a 12.5 kW/75 kWh iron flow battery connected to a rooftop PV system in Ukraine in partnership with KNESS and dpSun.
