Iron-air batteries can store energy for several days, making them ideal for balancing the intermittent supply of renewable energy sources like wind and solar. Due to their reliance on inexpensive materials, iron-air batteries are cost-effective, positioning them as a strong contender for large-scale storage, such as stabilizing the energy grid.
This cycle makes iron-air batteries an efficient option for storing and releasing energy, particularly well-suited for large-scale, long-duration energy storage applications. While iron-air batteries have a round-trip efficiency of around 50-60%, lower than lithium-ion batteries (which exceed 90%), their key strength lies in long-duration storage.
Iron-air batteries are known for their ability to store energy over long durations. This is particularly useful for applications like grid energy storage, where electricity produced from renewable sources like solar and wind needs to be stored for later use, sometimes over long periods.
Iron-Air Batteries Are Here. They May Alter the Future of Energy. Battery tech is now entering the Iron Age. Iron-air batteries could solve some of lithium ’s shortcomings related to energy storage. Form Energy is building a new iron-air battery facility in West Virginia. NASA experimented with iron-air batteries in the 1960s.
The Dutch startup Ore Energy just cleared a major hurdle for long-duration energy storage: completing what it says is the first iron-air battery system connected to the grid. Iron-air batteries, known colloquially as “ 100-hour batteries,” charge and discharge electricity through a reversible rusting process.
Companies like Form Energy have developed batteries capable of storing electricity for up to 100 hours, ensuring grid reliability during low renewable energy generation periods. Iron-air batteries could balance the grid and provide a reliable energy supply as the world pivots towards renewable energy.
