  • Energy Storage: Cheap Is Still Beating Cool [View article]
    Hey John,

    Curious what your thoughts are on ZBB's PECC technology.....something they co-developed with EATON Corp. A game changer, or something that anyone could copy if they wanted.

    Thanks and happy new year.

    Very nice article......thanks.

    I would add AXTI to this list.

    Check them out.

  • Energy Storage is Not Needed for Renewables Integration [View instapost]
    Engstudent, the NREL isnt the one thats actually going to IMPLEMENT AES (Advanced Energy Storage). Its the utilities, like PG&E and DUKE energy that ARE CURRENTLY implementing AES. This is from PG&E's SGIP program:
    California Public Utilities Commission (CPUC) rebate program initiated in 2001 to reduce peak demand on the grid
    Scheduled to continue accepting applications through 2012
    Provides incentives for the installation of new, qualifying self-generation equipment installed to meet all or a portion of the electric energy needs of a facility (Large Wind, Fuel Cell, and Advanced Energy Storage Systems)
    Program Administrators: 1. Pacific Gas & Electric Company (PG&E) 2. Southern California Edision (SCE) 3. Southern California Gas (SoCal Gas) 4. California Center for Sustainable Energy (CCSE) for San Diego Gas & Electric (SDG&E)

    Now, you have to ask yourself........why would they not only create a subsidy for AES but create an entire program around it, if they thought AES when it isnt needed?

    Now....since the utilities will likely be the ones buying and implementing AES, I guess it doesnt really matter what the NREL thinks.
