    1. Economics of EV Battery Reuse [promo for NAATBatt Annual Conference]

      Economics of EV Battery Reuse [promo for NAATBatt Annual Conference]
      Most of the discussion about reuse has centered on what the residual uses of the batteries are going to be. Many have talked about (and several are investigating) the repurposing of EV batteries for grid-connected energy storage. Use in residential power back-up and vehicle recharging station applications is also possible. The Chinese have mentioned plans to use repurposed EV batteries in street lights. The highest and best use of repurposed EV batteries is, however, still very much an open question.

    2. Report: High Temperature Energy Storage: NaS, NaMx and Molten Salt

      Report: High Temperature Energy Storage: NaS, NaMx and Molten Salt
      According to a new report by market research publisher SBI Energy, energy storage is a growing market critical to the advancement and optimization of smart grid transmission and distribution operations and to the integration of renewable energies in power generation. High temperature energy storage (HTS) technologies, including sodium-sulfur (NaS), sodium-metal halide NaMx, and molten salt thermal energy storage (TES), are gaining attention as the go-to technologies for large scale and utility scale energy storage.

    4. To Store or Not to Store: That is the Question

      To Store or Not to Store: That is the Question
      Whenever energy storage is mentioned the majority of us think batteries, however from a United States grid perspective, pumped hydro is the incumbent technology, followed by compressed air (CAES) and then the relativity new grid storage concepts of flywheels and electrochemical batteries. This order of preference is also representative of the capital cost, high to low, and the flexibility of deployment low to high—which is the fundamental driver for the growth of large format batteries on the grid. Although the largest potential benefit for storage on the grid is peak load shifting, other benefits are also realized in the form of: load firming, voltage support, frequency regulation, ramp management, community storage and security of the grid.

    5. How Renewables and Storage will Replace German Nukes

      How Renewables and Storage will Replace German Nukes
      Existing energy storage options are being maximised and new battery technologies rolled-out. With more than 17,000MW of installed capacity, Germany boasts more than half the world’s operating photovoltaic solar energy panels. More than 21,000 wind turbines, most of them onshore, provide another 27,000MW, while offshore development of a further 25,000MW in the North Sea is planned by 2030. By 2050, the country expects to generate 80% of its electricity using renewable sources.

    7. Solar (w/ Storage) Will Move Appalachia From Coal

      Solar (w/ Storage) Will Move Appalachia From Coal
      Figure 7 shows the decrease in the consumer price per kilowatt-hour (kWh) for solar energy over time. This cost includes the cost to install solar, install energy storage (beginning in 2020), maintain the solar array, and building the transmission infrastructure. While this decrease may not look like much at first glance, it’s much more desirable than the dramatic cost increases in Figure 8 if we were to stick with coal.

      UK Dept Risking "NEGawatt" Market by Lack of Payment Clarity
      The Department of Energy and Climate Change confirmed last week that it will develop a policy that will set out the role of electricity demand management initiatives, energy storage systems, new interconnection links to the continent, and the roll out smart grid technologies. The DECC has been warned it risks harming investor confidence in the UK's emerging "negawatt market", after failing to reveal how it will administer payments for back-up plants and demand management schemes.

    9. Report by Pike: “Energy Storage on the Grid”

      Report by Pike: “Energy Storage on the Grid”
      Pike Research anticipates that among the various application segments in this market, the integration of renewable energy – primarily wind power – will represent approximately 50% of the total capacity deployed for long duration energy storage. The firm forecasts that load leveling/peak shifting will represent 31% of the total market, followed by arbitrage (12%) and T&D upgrade deferral (7%).

    10. Opinion: The Missing Strategy for Storage

      Opinion: The Missing Strategy for Storage
      The reason that electricity is not stored in large quantities on the U.S. electricity grid today (other than 21.5 gigawatts of pumped storage hydropower) is because it is still generally less expensive to generate an electron than to store it. What is the case for government investment (either directly or through tax credits) in grid-connected energy storage technology? Why can’t the government leave development of grid-connected energy storage to the private sector alone?
