Redox flow batteries for $66/kWh from steel industry waste
U.S. researchers claim to have added iron sulfate to anthraquinone disulfonic acid in a redox flow battery for the first time. The scientists said the combination could lead to inexpensive and more stable redox flow storage for just $54/kWh and said $66/kWh is already possible.
Cheaper flow batteries with new membrane
US scientists claim to have discovered a membrane which could lead to cheaper large scale flow batteries. The material is an ion-selective, aqueous-compatible polymer with intrinsic microporosity known as AquaPIM and is said to have tunable thickness and high conductivity in aqueous electrolytes.
