Imagine a battery that works like a rust-and-unrust process to store electricity. Instead of using rare and expensive metals like lithium, it uses common iron and air to hold energy for days. It's like having a giant, safe energy tank in a shipping container that keeps the lights on even when the wind doesn't blow for a week.
Renewable energy is intermittent, leading to massive waste (curtailment) and a reliance on expensive, flammable lithium batteries that depend on scarce raw materials.
A modular, containerized iron-air battery system capable of multi-day energy storage using non-flammable aqueous electrolytes.
If you are a wind farm operator dealing with curtailment where up to 63% of capacity is wasted during peaks — this project developed a battery that stores energy for more than 100 hours to prevent energy waste.
If you are a factory owner dealing with high electricity costs and grid instability — this project developed a modular containerized storage system that is ~10x more cost effective than lithium ion.
If you are a grid manager dealing with limited transmission capacity and the need for energy sovereignty — this project developed a scalable, non-flammable storage solution to decongest the grid.
The F-AIR BAT technology is designed to be ultra-cheap, claiming to be approximately 10x more cost effective than lithium-ion batteries.
Yes, the system uses a modular containerized design that allows it to be deployed from commercial sites up to grid scale.
The technology is fully patent protected and originated from research at TU Delft.
While standard batteries typically store energy for a few hours, F-AIR BAT can provide more than 100 hours of storage.
It uses iron, water, and air, meaning it is free of critical raw materials like lithium, nickel, and cobalt, reducing supply chain outage risks.
The project is led by a single Dutch SME, Ore Energy BV, which maintains 100% industry representation. This lean structure suggests a fast-track approach to commercialization, focusing on the transition from TU Delft research to a market-ready product without the overhead of academic partners in the execution phase.
