What tech breakthroughs are emerging?
Indian researchers developed a sodium-ion battery capable of ultra-fast charging—up to 80% in six minutes—with more than 3,000 cycles of stability. With supply chains tightening around lithium, sodium-ion could soon provide a scalable alternative for stationary storage markets.
Who is facing financial or operational setbacks?
Australian manufacturer Energy Renaissance entered administration despite government support. Once seen as a flagship for domestic lithium-ion production, its collapse highlights the persistent economic challenges of localizing battery manufacturing outside Asia.
What’s happening on the investment and infrastructure front?
In Texas, Prologis Energy sold a 400 MW / 800 MWh BESS project in ERCOT’s congested zones. The deal underscores growing investor appetite for large-scale storage assets in one of the world’s most volatile and lucrative power markets.
What are the advancements in long-duration storage?
China completed the world’s largest vanadium redox flow battery project at 200 MW / 1 GWh, paired with a 1 GW solar farm. This milestone in long-duration energy storage demonstrates how flow technology can complement lithium-ion in stabilizing renewable-heavy grids.
