GE Energy Storage Technologies this week introduced the Durathon battery for uninterruptible power supply (UPS) systems that provide backup power for large data centers and hospitals. Durathon is based on sodium-metal halide technology rather than the lead acid batteries typically used in data center UPS systems. GE has invested in sodium-metal halide for use in hybrid locomotives, and is now adopting the technology for the UPS market. GE says its proprietary chemistry allows the Durathon battery to operate virtually maintenance-free for 20 years. The battery has a high energy density and is fully recyclable. At the Uptime Symposium 2010 in New York , we spoke with Herman Wiegman of GE Energy Storage Technologies, who provides an overview of the sodium-metal halide battery and its advantages.
