Flow batteries play a critical role in enabling renewable energy integration by addressing intermittency and grid stability challenges. Their unique design and scalability make them particularly suited for large-scale, long-duration energy storage needs.
Grid-scale energy storage
Flow batteries store excess renewable energy during peak production (e.g., sunny or windy periods) and discharge it during low generation or high demand. This helps balance supply-demand mismatches inherent in solar and wind power.
Long-duration storage
Capable of 4-40 hours of storage, flow batteries outperform lithium-ion for extended grid support, such as overnight wind lulls or multi-day cloudy periods. The liquid electrolyte design allows independent scaling of energy capacity (via tank size) and power output (via cell stacks).
Grid stabilization
They provide frequency regulation and reserve power to maintain grid reliability amid renewable fluctuations. Sumitomo Electric Industries’ 60MWh installation in Japan exemplifies this grid-balancing role, while its 49MW/173MWh global portfolio (41 projects) highlights widespread adoption.
Sector-specific uses
- Industrial collaborations: Mercedes-Benz and CMBlu Energy are deploying an 11MWh SolidFlow battery for renewable energy management.
- Zero-waste production: Companies like Quino Energy (MRL 7 certification) are advancing sustainable manufacturing methods for flow batteries.
These systems enable higher renewable penetration by decoupling energy generation from usage timelines, making them essential for decarbonizing electricity grids.
