Top five emerging energy storage technology companies

The new Lux Research Grid Storage Tracker reveals that the lineup of leading emerging energy storage suppliers is indeed seeing a significant shake-up. Japanese molten salt battery producer NGK Insulators has historically dominated the grid storage market for emerging technologies (excluding pumped hydro, compressed air, and traditional lead-acid batteries). After capturing over 76% of the total market at the end of 2010, NGK’s market share plummeted to just 53% of operating grid storage projects as of September 30th of this year, according to Lux Research’s Grid Storage Tracker.

NGK’s monopoly withered and allowed other players with a variety of technologies to make waves into the grid storage market, including Xtreme Power’s advanced lead acid battery, Beacon Power’s(Nasdaq:BCON)flywheels (although Beacon’s share will drop after filing Chapter 11 last week), and lithium ion batteries from International Battery and A123 Systems (Nasdaq:AONE),. The strong traction of these players resulted in a 56% increase in the number of installed megawatts in 2011 over 2010. Based upon announced and ongoing projects, NGK’s market share will sharply drop by the end of 2012 with A123 Systems capturing nearly one quarter of the market. 

The Lux Research Grid Storage Tracker, built upon data gathered from primary interviews with technology developers, is a customizable database and tool that keeps track of grid storage projects around the world from conception through operation and completion. The Grid Storage Tracker details each project’s technology, technology provider, status, size, location, cost, and applications and breaks down the market for battery components by cathode, anode, separator, and electrolyte. 

The Tracker is a flexible platform that allows the user to input proprietary data and manipulate Lux Research’s underlying assumptions. This dynamic tool supports an almost infinite quantity of easily customized graphical and data outputs ready for instant insertion into any reporting format.
