    1. 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.

      Renewables Boom Could Strain Germany's Grid
      Dena energy agency director, Stephan Kohler, said: "My demands for the new renewable energy laws would be that additional capacity is to be built only where there is an existing network infrastructure … Another prerequisite would be that it must be possible to absorb the new capacity through demand side management or integrate it in storage systems at a European level".

    4. Google Study: "Clean Energy Innovation" - Storage

      Google Study: "Clean Energy Innovation" - Storage
      Storage helps integrate intermittent renewables like wind and solar, shape demand, and prevent service interruptions. Two basic types of breakthroughs in grid-storage were modeled: short duration storage capable of discharging loads for less than 1 hour; and larger scale storage capable of discharging for over 1 hour. We then modeled five business cases for storage: 1) Frequency Regulation; 2) Load Following; 3) Price Arbitraging; 4) Capacity Deferment; and 5) Grid Reliability. State and federal policies remained the same as BAU.

    5. Opinion: The Alternative Energy Fallacy

      Opinion: The Alternative Energy Fallacy
      The basic premise of alternative energy is that widespread deployments of wind turbines, solar panels and electric vehicles will slash hydrocarbon consumption, reduce CO2 emissions and give us a cleaner, greener and healthier planet. That premise, however, is fatally flawed because our planet cannot produce enough non-ferrous industrial metals to make a meaningful difference and the prices of those metals are even more volatile than the prices of the hydrocarbons that alternative energy hopes to supplant.

    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.

    8. 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.

    9. 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.

      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.
