Advanced long‑duration energy storage

Overview

In July 2026 researchers in China and India unveiled prototype batteries aimed at providing multi‑day storage for renewable power. A flowing zinc‑slurry battery demonstrated over 5,000 hours of operation with high efficiency, while an Indian start‑up introduced an iron‑air battery capable of six‑hour full charging and 18‑hour discharge, targeting grid deployment by early 2027.

By early August 2026 European firms were moving from prototype to commercial scale. A Dutch start‑up secured a contract to install up to 1 GWh of iron‑air battery capacity, beginning with a 400 MWh phase slated for 2028, and an Austrian company promoted its SMRX system that couples electricity and heat storage to bolster energy security amid drought‑related plant shutdowns. The European efforts reflect a shift toward large‑scale, low‑cost, long‑duration storage solutions building on the earlier Asian technological advances.
