    1. Analysis: Is Sodium Sulfur (NaS) a viable Grid Storage Solution?

      Analysis: Is Sodium Sulfur (NaS) a viable Grid Storage Solution?
      In September 2011, sodium-sulfur (NaS) batteries at a Mitsubishi Materials Plant in Japan, caught on fire. It took firefighters more than 8 hours to control the blaze, and two weeks to extinguish the fire. NGK Insulators, the company that manufactured the storage system, does not know the cause of the fire, has suspended production of its NaS cells, and advised customers to refrain from using their batteries.

    4. Alberta Study: Energy storage key for wind power producers

      Alberta Study: Energy storage key for wind power producers
      Alberta (Canada) wholesale power prices fluctuate every 10 minutes. The new study, released this week, examined generation from several wind farms and power prices during that period. It found wind farms could have increased their revenue by up to 43% if they had been able to store power and add it to the market as demand - and prices - increased. When prices were lower, they could recharge their storage.

    5. To Store or Not to Store: That is the Question

      To Store or Not to Store: That is the Question
      Whenever energy storage is mentioned the majority of us think batteries, however from a United States grid perspective, pumped hydro is the incumbent technology, followed by compressed air (CAES) and then the relativity new grid storage concepts of flywheels and electrochemical batteries. This order of preference is also representative of the capital cost, high to low, and the flexibility of deployment low to high—which is the fundamental driver for the growth of large format batteries on the grid. Although the largest potential benefit for storage on the grid is peak load shifting, other benefits are also realized in the form of: load firming, voltage support, frequency regulation, ramp management, community storage and security of the grid.

    6. Grid-Scale Thermal Energy Storage Prospects

      Grid-Scale Thermal Energy Storage Prospects
      Future thermal energy storage will cover the temperature range from sub-freezing to 1000°C. Heat-of-fusion technologies offer greatly extended useful service lives and cost-competitive long-term costs. Most thermal energy storage systems will be built on a large scale that involve massive volume. Most future research may involve high-temperature systems that generate steam and energize air turbine engines.

    7. Bright Energy's Underwater CAES 'Bag'

      Bright Energy's Underwater CAES 'Bag'
      Bright Energy's core technology is a long, flexible polymer/glass bag shaped like a giant sea cucumber. One end of the bag is attached to an air hose on the surface. A self-standing system with its own generator could produce power for under 6 cents a kilowatt hour, the CTO said. If you could latch onto a generator at an offshore wind farm, the costs could potentially drop to 2.5 cents.
