Problem
Current battery technologies are often expensive to produce, environmentally unfriendly, and lack the capacity for long-duration energy storage, hindering the widespread adoption of renewable energy sources and requiring continued reliance on fossil fuels during periods of low renewable energy generation. This limitation prevents a fully decarbonized electricity grid.
Solution
Ore Energy is developing a long-duration energy storage solution utilizing a modular battery technology based on the reversible rusting of iron with water and air. This iron-air battery technology offers a cost-effective and scalable approach to storing renewable energy for extended periods. The battery discharges by "breathing in" air, converting metallic iron into rust, and charges by "breathing out" air, reverting the rust back to metallic iron. The modular design facilitates easy scalability and low maintenance.
Target Audience
The primary target audience includes utility companies, grid operators, and renewable energy project developers seeking affordable, long-duration energy storage solutions to enable a transition to a fully decarbonized electricity grid.
