This iron flow battery could power a more renewable grid

3-Second Blueprint (English)

1. Flow batteries decouple energy capacity from power hardware by pumping liquid electrolytes from external tanks through reaction cells.
2. Scaling storage duration only requires larger electrolyte tanks rather than adding expensive stacked electrode layers like lithium-ion.
3. Iron flow batteries use abundant iron and saltwater electrolytes to deliver low-cost, multi-hour grid storage for wind and solar power.
