    1. LightSail's Compressed Air Grid Storage Explanation (good overview)

      LightSail's Compressed Air Grid Storage Explanation (good overview)

      To make CAES more efficient, the LightSail system captures and stores both the mechanical energy and the thermal energy used in compressing air.  To do this, a water mist is infused into the compression chamber as the air is compressed. Water can hold 3,300 times as much heat as the same volume of air, and is able to capture the heat generated by the process more effectively.  Both potential energy in the form of pressurized air and the heated water can be stored.

    4. 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.

    7. 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.

      Report: by Research and Markets - "Energy Storage Report 2011 - Insights in New Technologies"
      Although while most interest in storage has focussed on grid-scale applications, there is also a large market for smaller, scale distributed storage. This includes storage at the consumer-side which could meet demand when the upstream part of the grid is offline. To illustrate the point, in 2010 grid-scale storage projects only accounted for just under a third of all storage deals.
