These plastic batteries could help store renewable energy on the grid


Susan Babinec, who runs the energy storage program, says conductive polymers could become a major player in grid storage, but whether that happens will depend on how quickly the company can scale its technology and most importantly the cost of batteries. at the Argonne National Laboratory.

Some Research It points to US$20 per kilowatt-hour storage as a long-term goal to help us embrace 100% renewable energy. A milestone of the other alternative grid storage batteries is being focused on. Form Energy, which manufactures iron-air batteries, says it can achieve this goal in the coming decades.

PolyJoule may not take the costs that low, Paster agrees. It’s currently targeting $65 per kilowatt-hour storage for its initial systems, suggesting that industrial customers and utility companies may be willing to pay that price because products need to last longer and be easier and cheaper to maintain.

Paster says the company has so far focused on building technology that is simple to manufacture. It uses a water-based manufacturing chemistry and uses commercially available machinery to assemble the battery cells, so it doesn’t need the special conditions sometimes required in battery manufacturing.

It’s still unclear what battery chemistry will gain in grid storage. But PolyJoule’s plastics mean a new option has emerged.
