Sodium-ion Market Updates From the US

Sodium-ion batteries are gaining traction in the U.S. as a promising alternative for data centers and UPS systems, thanks to their thermal stability (-40°C to 60°C), which reduces cooling costs. Their adoption is further supported by the Inflation Reduction Act's 30% tax credit for standalone energy storage, available until 2032. The U.S. holds a strong supply advantage, producing 12 million metric tons of natural soda ash in 2024, primarily from cost-effective and eco-friendly trona deposits. However, domestic Na-ion battery manufacturing remains limited, with no large-scale production of transition metal oxide sodium-ion cells. To address this, the DOE launched the $50M LENS Consortium in November 2024, focusing on cathode and electrolyte innovations rather than immediate commercialization. A 2024 DOE report found Na-ion battery costs to be among the highest for long-duration energy storage (LDES), largely based on sodium layered oxides, but China's shift toward Prussian white cathodes and hard carbon anodes could improve cost competitiveness. Despite these challenges, U.S. companies like Natron Energy, Unigrid Battery, Peak Energy, and Nadion Energy are emerging as key players in the Na-ion space.
