Electricity and Power Storage - Ares North America - 3 views

  • Advanced Rail Energy Storage (ARES), is a Santa Barbara, California based company, providing a deployable solution for grid-scale energy storage. ARES mission is to enable the electric grid to integrate unprecedented amounts of clean, environmentally responsible, renewable energy while maintaining the reliable electric service necessary to power growth and prosperity. Since it's founding in February 2010, ARES has developed and filed both domestic and international patents for an advanced method of utility-scale electrical storage. ARES facilities are designed to: provide grid security and reliability; support the increased use of renewable technologies, and to provide an energy storage solution that does not rely on water.

California Proposes First Renewable Energy Storage Requirements : CleanTechnica - 1 views

  •  
    "This bill will provide the first real boost to the renewable energy storage industry, as it secures a clean energy future for California. To bring 2.25% of peak demand in storage online, Jon Petersen estimates that (with 135 MW a year of storage needed) $200 million each year will need to be invested, along with the new jobs that all that new investment brings."

Utility energy storage no longer just giant batteries | Green Tech - CNET News - 0 views

  •  
    The Department of Energy on Tuesday announced that $620 million in stimulus funding is going to 32 smart-grid programs, which will be coupled with another $1 billion in private money. A total of $770 million from government and industry sources in the next few years will go to energy storage, giving a number of storage technologies a dose of real-world experience.

  • (The Volt will be a ful-sized four-passenger car with a range of about 65 kilometres using only its batteries. It is scheduled to go into production in the United States in 2010.)
  • The Volt will use a battery with a capacity of 16 kilowatt-hours of charge. But that battery won’t dip below eight kWh of charge, so a full nightly charge would be eight kWh - about the same amount of power as is consumed by a water heater, a plasma TV or a computer and monitor left on all day.

California ISO: Integration of Renewable Resources Program (IRRP) - 0 views

  • In support of the State of California Renewables Portfolio Standard, the California ISO (CAISO) has worked with Participating Transmission Owners, the California Energy Commission, the California Public Utilities Commission, industry experts, adjacent control areas and owners/developers of renewable resources to identify integration issues and solutions for the integration of large amounts of renewable resources into the CAISO Control Area.

Storage Boosts the Power of Renewable Energy - 0 views

  • "Grid-scale storage is here now. Storage should be deployed now at the gigawatt (GW) scale...where capacity, ancillary services and energy time-shifting are clearly needed."

Flat Panel Technology Boosts Solar Efficiency - 0 views

  • Xtreme Energetics has investigated the possibility of using mechanical trackers to perform the same light-focusing duties as other solar array manufacturers have. However, HP’s transparent transistor can do the job electronically, rather than mechanically, and significantly reduce the costs of such an installation. Such a solar array is known as a concentrating photovoltaic (or CPV) solar array. To date, CPV arrays are fairly expensive and cannot store energy, making them less useful. They also work best in specific sections of the world — those with the highest levels of solar radiation, such as the southwest United States and northern Africa.

IEEE Spectrum: Can plug-in hybrid electric vehicles keep the electric grid stable? - 0 views

  • After safety, the longevity of the batteries in a plug-in hybrid is the greatest unknown. Can a plug-in hybrid’s battery pack retain the bulk of its energy capacity over 10 years of daily use and more than 4000 full-discharge cycles? (For a deeper look at the challenges facing plug-in hybrid batteries, see “Lithium Batteries Take to the Road”.)[ LINK: http://www.spectrum.ieee.org/sep07/5490 ] As Don Hillebrand of Argonne National Laboratory, in Illinois, said tartly, “Batteries are the showstopper.”

    Periodic demands from the grid, even for only a small fraction of the battery’s stored energy, would clearly affect the cells’ life span—but no one has data on how much. Another open issue is the development of creative financing models for replacement battery packs costing several thousand U.S. dollars even after mass production is achieved.

    Third-party battery leasing could be one answer, if combined with a secondary market for batteries whose performance has fallen below automotive levels. Carmakers, electric utilities, and large consumer-financing groups are quietly batting around these notions to see if they can build a financial model that makes sense for all three parties.

Technology Review: Fixing the Power Grid - 0 views

  • Large-scale power storage is crucial to our energy future: the Electric Power Research Institute, the U.S. utility industry's leading R&D consortium, says that storage would enable the widespread use of renewable power and make the grid more reliable and efficient.

DOE Awards First Three Large-Scale Carbon Sequestration Projects - 0 views

  • Plains Carbon Dioxide Reduction Partnership; Southeast Regional Carbon Sequestration Partnership; and Southwest Regional Partnership for Carbon Sequestration - will conduct large volume tests for the storage of one million or more tons of carbon dioxide (CO2) in deep saline reservoirs. These projects will double the number of large-volume carbon storage demonstrations in operation worldwide.
  •  
    U.S Deputy Secretary of Energy Clay Sell today announced that the Department of Energy (DOE) awarded the first three large-scale carbon sequestration projects in the United States and the largest single set in the world to date.

Technology Review: Storing Solar Power Efficiently - 0 views

  • Their schemes come with a caveat, of course: without backup power plants or expensive investments in giant batteries, flywheels, or other energy-storage systems, this solar-power supply would fluctuate wildly with each passing cloud (not to mention with the sun's daily rise and fall and seasonal ebbs and flows). Solar-power startup Ausra, based in Palo Alto, thinks it has the solution: solar-thermal-power plants that turn sunlight into steam and efficiently store heat for cloudy days.
