PROBLEM FOCUS
Renewable energy, especially solar in the Global South, is abundant and affordable, but intermittency limits round-the-clock use. Existing batteries are costly for LDES and have concentrated supply chains, leaving grids and industries reliant on fossil fuels when the sun isn't shining.
TECHNOLOGY SOLUTION
Meine Electric's iron-air batteries store energy through reversible rusting, using abundant, non-flammable materials including iron, water, and air. Its proprietary three-electrode design enables a full charge in about six hours, compared with up to 100 hours for traditional iron-air batteries, while providing 12–18 hours of storage. Designed for daily cycling, the system provides affordable long-duration storage to turn intermittent renewables into reliable, round-the-clock power.
