Inlyte Energy has successfully completed a factory acceptance test for its first field-ready iron-sodium battery energy storage system, marking a significant milestone from lab to grid reality. The test, attended by representatives from Southern Company, demonstrated the system's performance and integration readiness. Iron-sodium batteries are emerging as a viable alternative to lithium-ion for grid-scale applications, offering benefits like cost-effectiveness, safety, and long-duration performance.
