A new 500 MWh partnership between Alsym Energy and Juniper Energy will test whether sodium-ion batteries can carve out a durable role in hot-climate grid storage where thermal performance and cooling costs matter.

Battery storage company ESS is moving beyond its long-duration roots and into the short- and medium-duration market with a sizable sodium-ion addition to its project portfolio.

ESS Tech says it will add 8.5 GWh of U.S.-made sodium-ion cells and modules to its portfolio through a planned strategic partnership with Alsym Energy, broadening its non-lithium storage lineup.

A three-year, 60 GWh supply agreement between CATL and HyperStrong signals that sodium-ion batteries are moving from pilot-scale promise toward commercial energy storage deployment.

Renalfa Power Clusters plans to merge a large solar plant and standalone storage project in western Romania, then expand the site with both lithium-ion and sodium-ion batteries plus grid-forming technology.

A French non-profit is urging the government to require storage on new renewable projects above 10 kW, arguing sodium-ion batteries made in Europe could help absorb solar variability without relying on imported metals.

A sodium-ion battery prototype from BAIC Group achieves 11-minute full charging and 450 km range, as global sodium-ion shipments surge 150% in a year toward mass-market deployment.
