Answers to commonly asked questions

01

What is an Iron Flow Battery (IFB) and how does it work?

An Iron Flow Battery (IFB) is a type of energy storage system that uses iron salts dissolved in liquid electrolytes to store and release energy. It works by charging and discharging electricity through an electrochemical process, which allows the system to store energy for long periods and release it when needed.

02

How long can the R.Flo battery last?

Our Iron Flow Battery is designed to last over 40,000 charge-discharge cycles, equivalent to around 50 years of use with minimal degradation in capacity and efficiency.

03

How can the R.Flo battery reduce my energy costs?

By storing energy during off-peak times when electricity is cheaper and discharging it during peak demand, R.Flo can help C&I customers reduce their electricity costs by up to 25%. Additionally, for energy developers and utilities, it can offer a 30% higher internal rate of return (IRR).

04

Is the R.Flo battery system safe for industrial use?

Yes, the R.Flo battery is both safe and environmentally friendly. Unlike lithium-ion batteries, it has no risk of explosion, uses fully recyclable electrolytes, and contains non-toxic materials like iron, which is abundant and affordable.

05

What makes R.Flo different from other energy storage technologies?

R.Flo stands out because of its low-cost, fully recyclable iron electrolyte, long lifespan of 40,000 cycles, and ability to provide long-duration energy storage (6+ hours) at a much lower cost than lithium-ion batteries. It’s ideal for applications where stability and longevity are key.

06

What applications is the R.Flo battery best suited for?

R.Flo is ideal for commercial and industrial (C&I) customers, renewable energy developers, and utilities looking for long-duration energy storage solutions. It can be used for grid balancing, renewable energy storage, energy arbitrage, and backup power.

07

What are the maintenance requirements for the R.Flo system?

Our Iron Flow Battery system requires minimal maintenance. Thanks to the durability of the materials and our patented rebalancing technology, the system can operate efficiently for many years with little upkeep.

08

How can I integrate the R.Flo battery into my existing energy system?

Our team offers full support for the integration of R.Flo into your existing infrastructure. The system is modular and scalable, making it easy to fit into your current energy setup and expand as needed.
