    1. Solar Energy Needs Electrical Storage Now [good presentation]

      Solar Energy Needs Electrical Storage Now [good presentation]

      Dramatic cost reduction in photovoltaics (PV), combined with lower electrical storage costs from batteries for the automotive industry, are creating new business opportunities for grid-tied PV systems that include energy storage. This article addresses the technical and economical justification for electrical storage with PV and what it means for the PV industry.

    2. California: Ground Zero For Battery-Backed Solar (brief overview of many storage companies)

      California: Ground Zero For Battery-Backed Solar (brief overview of many storage companies)

      As renewables grow into double-digit penetration on the grid, they’re expected to need careful management by utilities seeking to balance them. While weather and load forecasting, smart inverters, demand response and other smart grid-enabled technologies can handle some of the intermittency, much of it must be backed up with real power, either with natural gas-fired peaker plants or with energy storage.

      GE's new battery - more details

      [This article provides more details than the original July 10 news.]

      The batteries could also be used to store power from wind turbines and solar panels to even out fluctuations in these power sources. GE also says they could be used in microgrids, small grids that are often the size of a village or military base and are designed to operate independently of the larger electrical grid while still getting grid-quality electricity.

    4. Brief explanation of major electrochemical and mechanical storage systems

      Brief explanation of major electrochemical and mechanical storage systems

      Some storage is mechanical (flywheels, pumped hydro, compressed air). These have low energy efficiencies and slow response times. Pumped hydro and compressed air storage systems are also restricted by geography, high investments, and long construction times.  Electrochemical energy storage systems – batteries – offer many benefits and advantages compared with other forms of storage.

    6. Grid-scale Energy Storage: Lux Predicts $113.5 Billion in Global Demand by 2017

      Grid-scale Energy Storage: Lux Predicts $113.5 Billion in Global Demand by 2017
      Last month Lux Research released a bottom-up evaluation of the cost effectiveness of eight energy storage technologies in six grid-scale applications throughout 44 countries, including all 50 U.S. states. Their report titled "Grid Storage under the Microscope: Using Local Knowledge to Forecast Global Demand" predicts that annual global demand for grid-scale energy storage will reach an astounding 185.4 gigawatt-hours (GWh) by 2017 and represent a $113.5 billion incremental revenue opportunity fo

      NGK £3.3M NaS Battery in Scotland remains dormant; may be removed unused due to fire risk

      The controversial £3.3M 1MW NGK sodium-sulphur battery at Lerwick [Scotland] power station is not likely to be energised until later this year, and may be removed unused.  A serious fire in a similar NGK battery in Japan halted the the project just as the battery was ready to be activated.  It was the third NGK battery fire, and the formal investigation by the Japanese fire service has taken over five months.

    9. 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.

      Rubenius in Mexico and Arab Emirates revisited (comments below article are very useful)
      An energy storage expert said that Rubenius had done little research on the California market before making announcements, that the project was on the wrong place on the grid, and the firm had little coordination with NGK. And Greentech Media has just learned of layoffs at the firm. A source close to the company said that the firm was "letting go of people left and right."

      GM Volt fire lessons for stationary battery companies
      [Curator: This Economist article about the GM Volt Li battery fires has lessons for the stationary battery market. The fire/explosion of the NGK NaS battery at Mitsubishi is analogous. Reportedly, the fire stopped NGK's sales, halted production, raised fears about installed batteries, and enabled a single ordinary citizen to delay, and potentially prevent, the activation of an already-delivered, strategically important battery (relevant articles are in the archive).]
