Company Background Information
Overview
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!
