AI Data Centres Need Big Batteries But Lithium Isn’t Fit-For-Purpose

AI-summarised brief · reviewed before publication

AI data centres face significant storage challenges due to their unpredictable power consumption patterns. As AI-driven data centres scale, they draw large amounts of power in short, burst-driven intervals, creating grid instability. Traditional lithium-ion batteries are not suitable for this purpose due to their rapid degradation and high costs beyond four to six hours of storage. Flow batteries offer a more reliable and cost-effective solution for multi-hour and repeat cycling scenarios.

💡 Why It Matters

  • · Fossil firming becomes the default fallback if storage architecture is underbuilt or mismatched to load volatility, prolonging the use of fossil generation.
  • · By investing in storage technologies designed for high-cycle operation, AI data centres can help fast-track a clean energy future.
