Ore Energy's iron-air storage tech successfully stored energy for 100 hours in France, offering a rare-earth-free, scalable solution for renewable grids.
A Netherlands-based startup, Ore Energy, successfully tested its iron-air long-duration energy storage system in France under the EU’s StoRIES programme, demonstrating the ability to store and discharge energy for up to 100 hours using only iron, water, and air.
The grid-connected pilot, conducted at EDF’s R&D facilities over several months, validated the technology’s performance under real-world conditions, supporting Europe’s goal of reliable, renewable energy storage without rare earths or critical minerals.
The modular system, deployed in 40-foot containers, uses a reversible oxidation process and aims for gigawatt-hour scale by 2030.
Results are being shared publicly to advance Europe’s energy storage knowledge base.
