| Ore Energy | Ore Energy develops long-duration energy storage systems based on iron-air battery technology for renewable energy applications and electric power grids. The company researches, develops, and manufactures modular battery systems that use iron, water, and air to store electricity through a reversible oxidation process, enabling multi-day energystorage using abundant materials. Its technology supports grid-scale energy storage, renewable energy integration, grid balancing, and backup power by extending storage duration beyond conventional lithium-ion battery systems.Ore Energy also conducts research in electrochemistry, battery engineering, manufacturing processes, and energy storage system design to improve scalability, safety, and operational efficiency. The company's battery platform is designed to help utilities, renewable energy developers, and industrial customers store excess renewable electricity and enhance grid reliability while supporting the transition to low-carbon energy systems. | $43M | Series A | Aug 04, 2026 |  |
