Even though lithium batteries are still the most common way to store energy – a challenge the world must overcome in order to substitute renewables for fossil fuels – they clearly create serious problems too, and that’s why they’re not a viable option for a sustainable energy transition. To replace lithium, alternatives are being developed around the world, such as iron-air batteries, whose commercial production in the United States is expected to begin as early as 2024.
Iron-air batteries were developed by Form Energy, a startup spun out of the prestigious Massachusetts Institute of Technology (MIT).
Form Energy’s batteries, according to US media, are ten times as cheap as lithium batteries, and they use iron, which is abundant all over the world. At the same time, iron-air batteries can last longer than lithium batteries, and are also safer, as…
Iron-air batteries are 10 times as cheap as lithium, and will be produced from 2024
