    2. 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.

    3. Little State Money for Utility Upgrades

      Little State Money for Utility Upgrades
      Tight budgets affect electric utilities that need to find their own financing to pay for upgrades. It's a complicated process that in many states requires approval of the public utility commission for any rate increases. One Senate proposal would use $10 billion in federal seed money to establish an independent bank that gives out loans and loan guarantees to major infrastructure projects.

    4. Tohoku Electric To Stack 40 NGK 2MW NaS Batteries

      Tohoku Electric To Stack 40 NGK 2MW NaS Batteries
      Tohoku Electric Power Co. will set up a sodium sulfur (NaS) storage system at its Noshiro fossil-fuel-burning power plant. The system is comprised of forty 2MW NaS batteries from NGK, and has a total output capacity of 80MW. It is expected to be running in January, and when fully charged, it will provide continuous power for roughly six hours. It is expected to be one of the biggest of its kind in Japan.

      BC Hydro, NGK, S&C Electric team on project
      The project involves two 1MW batteries. The battery near Golden will supplement the community’s power supply during peak periods. The battery in Field will store up to seven hours of reliable back up supply that could be used during an outage. The batteries will be supplied by NGK Insulators, and the system will be engineered and installed by S&C Electric Company.

      Primus Power Full Demo of Grid-Scale 25MW Flow Battery

      Primus Power is building a farm of flow batteries that promise to offer 25 MW of power for up to 3 hours for the Modesto Irrigation District (Modesto, California’s utility provider). This battery farm is a full-scale demonstration system, and will store the region’s wind-generated energy as well as providing an alternative to fossil-fuel-fired generation.

    7. White House Releases "A Policy Framework For The 21st Century Grid"

      White House Releases "A Policy Framework For The 21st Century Grid"
      Energy storage systems have the potential to optimize the operating capabilities of the grid and the use of renewable energy by storing power for later use Such systems can work more effectively in tandem with smart grid technology, can augment demand response resources to reduce and shift peak energy loads, and can improve power quality and service reliability. Significantly, utility-sited energy storage can be used to avoid or delay investments in new distribution capacity and substation equipment. Today, only about 2 5% of U S electricity is provided through storage, although other countries, such as Japan, use storage for up to 15% of their energy needs.

    8. Utilities Attitudes & Priorities: Survey by Black & Veatch

      Utilities Attitudes & Priorities: Survey by Black & Veatch
      Black & Veatch’s Strategic Directions in the Electric Utility Industry survey results have captured the changing electric utility trends in the United States for half a decade. This year’s survey once again explored traditional utility-focused questions regarding operations and regulations, in addition to asking about the timing of emerging technologies and their respective impacts on the industry.

    9. UK: Wasted wind

      UK: Wasted wind
      Currently, the actual amount of electricity wasted is very small, as the grid turns off coal rather than waste wind. But as we increase the amount of wind power on the grid, the problems will increase. The government's chief scientific adviser on climate change, Professor David MacKay, says: "We will have to put in complimentary amounts of balancing services, which could be inter-connectors [with Europe], pumped storage, demand shifting or mothballed gas power stations," he says.

    10. Li-ion Battery Startup Seeo Raises $15M

      Li-ion Battery Startup Seeo Raises $15M
      Seeo has been rather quiet about its battery innovation, but we do know that the company has been developing a nano-structured lithium-polymer battery, and in particular has been working on a solid electrolyte that was developed at Lawrence Berkeley National Lab. The material, which Seeo began licensing from the lab in 2007, allows for a more stable battery with higher energy density, in contrast to the more easily flammable liquid electrolyte that can present a safety risk in some conventional lithium-ion batteries.

    11. PG&E Grid-Scale Storage Demo Projects

      PG&E Grid-Scale Storage Demo Projects
      PG&E does have another pumped hydro site in development, Mokelumne, that's potentially the same size as Helms and has the potential to be used to help buffer the 4,500 megawatts of wind power coming in from the Tehachapi wind developments. So, PG&E understands pumped hydro. Electrochemical storage might be a different story. PG&E has two pilot projects using sodium sulfur (NaS) batteries from NGK. NGK's NaS batteries were selected because they are one of the few technologies and vendors with a performance and reliability track record. According to Thalman, the pilot can help the ISO develop the storage markets with this testbed.

      Grid storage part of SolarTAC joint solar research facility
      The facility, which broke ground in 2009, is intended to attract companies that want to build, test and research their solar technology, advancing the technology to the marketplace. SolarTAC — or Solar Technology Acceleration Center — is a joint operation among six entities, including Xcel Energy, Abengoa Solar and SunEdison. MRIGlobal manages and operates the site.
