Wrote a piece on vanadium redox flow batteries this week. These things have a property that lithium-ion fundamentally can't match for grid applications: you can add more energy storage by adding more electrolyte tanks without touching the power hardware. 12,000+ cycles with minimal degradation versus maybe 2,000–3,000 for lithium under heavy grid cycling. The Dalian facility in China (400 MW / 1600 MWh) went online in 2022 and it's one of the largest anywhere. Sumitomo Electric has been running commercial units in Japan for years. Not replacing lithium-ion in EVs anytime soon — the energy density is way too low. But as a grid buffer for multi-hour renewable storage? The math is different. The full write-up's in the flow if anyone wants the breakdown.
