Scientists created an inexpensive battery made by iron, that can discharge power for days.
Form Energy develop an ‘iron-air’ battery, that stores electricity for days through rusting, at a fraction of the cost of lithium-ion equivalents.
“Our pioneering battery technology will reform the global electricity system to run on 100% low-cost renewable energy, every day of the year.”
New Iron-air batteries are the best solution to balance the multi-day variability of renewable energy due to their extremely low cost, safety, durability, and global scalability.
“Our first commercial product using our iron-air technology is optimized to store electricity for 100 hours at system costs competitive with legacy power plants. This product is our first step to tackling the biggest barrier to deep decarbonization: making renewable energy available when and where it’s needed, even during multiple days of extreme weather, grid outages, or periods of low renewable generation.”
Greg Ludkovsky, Global Head of Research and Development at ArcelorMittal, said:
“Form Energy is at the leading edge of developments in the long-duration, grid-scale battery storage space. The multi-day energy storage technology they have developed holds exciting potential to overcome the issue of intermittent supply of renewable energy. They are exactly the kind of ambitious and innovative company we are seeking to invest in through our XCarb™ innovation fund.”
