We're a Boston-based energy storage company pioneering conductive polymer battery technology. We have re-invented what a 21st century grid battery should be: Ultra-Safe, Sustainable, Long-Life, and Low-Cost.
Providing power and energy for the grid today and tomorrow, PolyJoule's conductive polymer energy storage provides a cost-effective, safer path to 21st century electrification: at urban load centers, remote outposts, and anywhere in-between.
We have commercially operational systems and will be deploying at MW scale in 2024.
