Startup Ore Energy has signed an agreement with a utility in the Netherlands to deploy up to 1,000MWh of multi-day-duration iron-air batteries.

Long-duration energy storage (LDES) technologies are becoming increasingly viable options to add flexibility to the European electricity network, according to a new report.

APAC’s AI data centres look set to lock in a decade of coal and gas dependency, but long-duration energy storage can break that cycle, says Pavina Adunratanasee of ArkTerra Partners.

RWE Renewables Australia has officially opened the 50MW/400MWh Limondale battery energy storage system (BESS) near Balranald in south-west New South Wales.

ESN Premium speaks with Dr Thomas Sisto, of flow battery developer XL Batteries, about using LDES to combat grid strain from heatwaves and data centres.

The solar PV and energy storage expo SNEC 2026 in Shanghai, China, was the place to see product launches and showcases from the big players.

The European Commission must “acknowledge the clear role of long-duration energy storage,” organisations including Energy Storage Europe and the LDES Council have urged.

Managers of the UK’s largest BESS owner-operator Gresham House Energy Storage Fund (GRID) discussed recent investment news and future strategy this week. 

RWE has received official sign-off from the AEMO and Transgrid to operate Australia’s first 8-hour BESS at full capacity.
