Iron-flow battery research aims to reduce storage costs

By Michelle Froese Written by Craig WalkerContributor
The demand for large, utility-scale energy storage systems is expected to increase with the development of renewable energy projects. The variability of renewables poses added challenges to electric grid operators, who must balance the grid reliably. Energy storage is one way to store excess power for later use or emergency backup.
“Wind and solar power have high ramping rates and this creates a need to make up that demand,” explains Dr. Robert
