    1. 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.

    2. Military Wants Bases to be "island microgrids": Storage + Renewables

      Military Wants Bases to be "island microgrids": Storage + Renewables
      Energy officers at military bases are working to turn their facilities into "island microgrids"--entities that can generate and store their own electricity, independent of the surrounding commercial grid. … in the event of a blackout, it could continue to function on electricity generated on-site--largely from renewable sources. These include utility-scale solar arrays, backed up with advance-battery solar-power storage units and diesel generators … Energy experts say that the military's approach could also offer a new model for towns and cities, protecting them from regional-grid blackouts--and boosting local renewable-energy production.

    4. Microgrids promote energy independence

      Microgrids promote energy independence
      The Sacramento Municipal Utility District demo a "microgrid" that many other utilities have resisted. Microgrids promote energy independence, even allowing customers to secede from the larger utility grid powered up by their own resources. In an energy sector dominated by monopolies and centralized planning, microgrids could be a game-changer.

      Nokia-Siemens base station for mobile (cell) service
      Nokia Siemens Network (NSN) has set up a base station for German mobile service provider E-Plus that is powered by renewable energy. The transmission plant relies on a combination of solar and wind power, supported by fuel cell and deep-cycle battery technology. It is the first base station to operate without using Germany’s grid electricity.

    7. Research: Iron vs Vanadium for solar flow battery storage

      Research: Iron vs Vanadium for solar flow battery storage
      Researchers around the world are already building successful flow batteries, but usually using Vanadium, a rare metal mined in Russia and South Africa that sells for $8 to $25 per pound in its raw form, according to the release. Iron, on the other hand, is plentiful in North America and sells for just 25 cents per pound after processing.
