- Inlyte Energy completes factory acceptance test of its first field-ready iron-sodium battery energy storage system.
- The test was witnessed by Southern Company, a major US utility, proving system performance and integration readiness.
- Iron-sodium batteries are emerging as a compelling alternative to lithium-ion for grid-scale use due to abundant materials and safety.
- Iron-sodium systems are better suited for multi-hour to multi-day grid applications, offering cost efficiency and long service life.
- The global energy storage market is projected to grow from $70 billion in 2025 to over $150 billion by 2030.
- Inlyte's system achieved 83% round-trip efficiency, comparable to high-performance lithium-ion systems.
- First deployments will be at Southern Company’s Energy Storage Test Site in Alabama in early 2026.
- Inlyte plans to establish a US manufacturing site in 2026, partnering with HORIEN Salt Battery Solutions.
- Commercial deliveries of domestically produced systems are expected to begin in 2027.
