About the company:
Unlike conventional batteries, our systems use abundant, non-toxic materials: iron, air, and water. This makes them safe, cost-effective, and scalable without relying on scarce minerals or fragile supply chains. When charging, the battery converts rust into metallic iron. When discharging, it reverses the reaction, consuming oxygen and producing rust again. This simple, proven chemistry has the potential to deliver energy at a fraction of the cost of other storage technologies.
Founded at TU Delft in the Netherlands, Ore Energy is focused on real-world deployment. In 2025, we connected the world's first iron-air battery to the grid in Delft. This milestone demonstrated that multi-day storage can be integrated directly into modern energy systems.
As countries expand renewable generation, the challenge of balancing supply and demand is becoming urgent. We believe long-duration storage is a critical part of the solution and that it must be safe, sustainable, and affordable at scale.
Ore Energy’s mission is clear: to store renewable energy anywhere, for as long as needed, using materials that are available to everyone. By combining deep electrochemistry expertise with practical engineering, we are turning one of Earth’s most abundant resources into a cornerstone of the clean energy transition.
