Ore Energy raises €38 million for iron-air batteries

8 September 2026

Delft-based Ore Energy has raised 38 million euros to build its first battery factory. The startup is developing so-called iron-air batteries: batteries that store energy through a reversible rusting process. With this investment, the company aims to begin commercial-scale production starting in 2028.

Iron-air batteries offer a cost-effective solution for long-life energy storage, which is crucial for the integration of renewable energy. A major advantage is that iron-air batteries do not contain lithium or cobalt, thereby reducing costs and supply chain risks. This project aims to improve their efficiency by developing and optimising advanced electrode materials specifically for iron-air battery applications.

Successful pilot

Earlier this year, Ore Energy completed a successful pilot with the French energy company EDF. In addition, the company signed an agreement with energy supplier Budget Thuis, which has reserved a total of 1 GWh of storage capacity.

The plan

Ore Energy has not yet announced where the first factory will be located or what its production capacity will be. It is clear, however, that the new funding will be used entirely to make the transition from pilot projects to commercial production. With this move, the Delft-based startup joins a growing group of companies developing alternatives to lithium-ion technology, including the American company Form Energy.

The first 400 MWh is scheduled to be delivered in 2028. The batteries are designed to store renewable electricity for 24 to 100 hours, thereby supporting the power grid.
