Iron-air batteries use rust from iron to store energy, providing an efficient and low-cost alternative to lithium-ion batteries. These batteries are made of iron, air, and water, making them environmentally friendly and reducing reliance on rare earth minerals. Iron-air batteries can store energy for up to 100 hours, addressing the need for longer-term energy solutions, particularly in wind energy contexts. In contrast to lithium-ion batteries, which are ideal for short-term storage, iron-air batteries present significant advantages in terms of cost, safety, and efficiency, making them suitable for fluctuating energy supply situations.
On a megawatt-hour basis, our batteries are 5 to 10 times cheaper than lithium-ion batteries, making them an economically viable option for energy storage.
Because the batteries don't use rare earth minerals, the company also doesn't have to rely on complex supply chains or worry about tariffs.
Iron-air batteries can provide long-duration storage, up to around 100 hours, making them well-suited for covering gaps in energy production, especially with wind energy.
