Problem
Grid-scale energy storage remains constrained by short-duration, costly, and safety‑critical battery technologies, leading to renewable curtailment, reliance on fossil‑fuel backups, and limited resilience for microgrids and remote sites. Existing solutions lack the capacity and economic scalability needed for multi‑day or seasonal storage.
Solution
Flow6 Energy offers an all‑organic, non‑metallic flow battery that delivers high energy density in a compact footprint while using inexpensive, non‑toxic components. The system’s liquid organic electrolyte enables scalable storage capacity and discharge durations measured in days to weeks, addressing the long‑duration storage gap. Its fully recyclable chemistry eliminates hazardous waste and reduces fire risk, meeting stringent safety and environmental standards. By integrating with grid‑level power electronics, the battery provides frequency regulation, black‑start capability, and seamless renewable integration, supporting both utility‑scale grids and autonomous microgrid deployments.
Target Audience
Primary customers are utility operators, renewable energy project developers, and microgrid managers seeking safe, cost‑effective, long‑duration storage solutions for grid stability and off‑grid resilience.
