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.
To get long-duration storage costs down to $0.05/kWh, research teams funded by ARPA-E are pursuing breakthroughs in flow batteries, hydrogen storage and other technologies – even thermovoltaics.
A team at the renowned Massachusetts Institute of Technology has developed a type of battery which it says could store energy for long durations at a fraction of the cost of current storage technologies.
The Texas-headquartered firm will provide grid stability for Power Grid Corporation of India Limited in Puducherry with its flow battery systems.
