In response to increased demand for energy storage during Europe's heatwave, US company Unigrid is focusing on sodium-ion battery technology. This alternative to lithium-ion batteries is seen as potentially cheaper and safer, with the ability to operate in extreme temperatures. However, US manufacturers currently rely on China for sodium-ion cell production.
Watch for Unigrid's progress in US sodium-ion battery production, especially as they navigate safety concerns and material sourcing. The success of US firms like Emerald Battery Labs and ESS Tech could reshape energy storage dynamics, particularly for data centers.
