This SBI Bulletin reviews the major energy storage technologies that are either currently commercialized or in such advanced stages of development that they are likely to impact energy storage markets 2006-2015..

  • Pumped hydro storage,
  • CAES,
  • Electrochemical,
  • Flywheel,
  • Rechargeable batteries: lead acid, Lithium-Ion, Molten Salt, Vanadium Redox flow, zinc bromine
Additional emerging technologies and solutions are receiving attention for potential use in energy storage within the utility sector. While some level of development, demonstration or commercial activity is ongoing, vario challenges inhibit each of their widespread adoption before 2015.

These emerging areas include:

  • Superconducting magnetic energy storage (SMES)
  • thermal storage (TS)
  • vehicle to grid (V2G)
An overview of each energy storage technology presented is accompanied by identification and discussion of select developers and suppliers of the technology and detailed information regarding industry activity.
