    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.

    3. Renewables Boom Could Strain Germany's Grid

      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.

    6. ABB Pumped Hydro Makes a Canary Island 100% Renewably Powered

      ABB Pumped Hydro Makes a Canary Island 100% Renewably Powered
      The project’s goal is to provide inhabitants with all the energy they need through a combination of wind energy, pumped water-storage power and solar-thermal and photovoltaic systems. ABB is helping to lead the project by providing technology to electrify and control the hydro-power plant and integrate energy from renewable sources into the island’s grid.

    7. S&C Electric to Furnish a Turnkey NaS Storage System

      S&C Electric to Furnish a Turnkey NaS Storage System
      Southern California Edison (SCE) awarded S&C Electric a contract to furnish a turnkey 1-MW S&C Smart Grid SMS™ Storage Management System on Catalina Island, California. With no tie to the mainland, Catalina's diesel generators are not best equipped to handle power demand, which fluctuates throughout the day. By deploying stored energy during times of peak power demand, the Smart Grid SMS with NaS batteries permits Catalina Island generators to run at a specific percentage of capacity for optimal performance and decreased carbon emissions.

    8. 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.
