Flux XII is building grid batteries to expand renewable electricity. This has economic, reliability, and emission impacts. Instead of burning dirty carbon fuels for energy, we upgrade sustainable carbon feedstocks to store clean energy. We’ve developed organic chemistries with targeted flow battery properties, produced them in industrial batch reactions, and are testing them in prototypes that could about power a house!

"I'll do what I can to create as much chaos as I possibly can, but my chaos is always well-natured or has a positive goal at the end of it. When I start causing chaos in a situation it's because the situation really needed to be changed." - Joe Strummer (The Clash)
