    1. 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.

    2. 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.

    4. 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.

      GE Invests $14.4M in SustainX Compressed Air Storage
      New Hampshire-based SustainX has received US$14.4 million from GE Energy Financial Services and other investors to continue developing its compressed air energy storage technology ... GE Energy Financial Services joins Cadent Energy Partners and prior investors Polaris Ventures and Rockport Capital in the new round of venture financing, details of which were not disclosed. A total of $5.4 million in earlier financing for SustainX came from the Small Business Innovation Research programme of the National Science Foundation and from the Energy Storage Program of the US Department of Energy. AES Energy Storage LLC is working with SustainX to demonstrate a full-size system in the field.

    7. Nat Gas vs Batteries for grid renewable sources

      Nat Gas vs Batteries for grid renewable sources
      Grid storage via batteries could smooth out the variability of solar and wind’s [intermittencies, but providing 400 megawatts to meet California's projected needs] would be cost prohibitive. The real answer to improve alternative use and reduce greenhouse gases lies [with] natural gas-fired plants … GE just announced a $500M+, 510MW combined-cycle power plant … [with 61%] fuel efficiency, and can ramp up [its] output at over 50MW per minute.

    9. PG&E Sinks Wave Power

      PG&E Sinks Wave Power
      California utility PG&E is finally giving up on wave power ... essentially it has abandoned all wave power projects it had been researching, including pilot projects and permits for three areas along the California coast ... According to research done by Black and Veatch last year, ocean power — both wave and tidal — have one of the highest levelized costs of energy (the cost over the life of the system) out of all the clean energy generation options.
