  •  Storing H as NaH pellets (1+ / 0-)
    Recommended by:

    There was once a company called Powerball Technologies ( that was working on a hydrogen storage method.  You can read its old web site at

    Sodium hydride (NaH) pellets were wrapped in a thin plastic skin and stored in a water tank.  A blade would slice a pellet, and the sodium hydride released would form hydrogen gas (H2) and sodium hydroxide (NaOH).  When the fuel was depleted, the waste skins and NaOH would be replaced by a new supply of water and NaOH pellets.  The waste skins could be recycled for more pellets, and the NaOH could be heated up to break the NaOH down into oxygen and NaH, which would then be used for more pellets.

    Aside from the issue of how to deal with cold winters (which wouldn't be an issue in warmer climates), what do you think of this idea of energy storage?

    You might be a Rethug if you join forces with the tobacco lobbyists but condemn abortion, birth control, and gay marriage as crimes against humanity.

      Warmest regards,


      Fool me once, shame on you. Fool me twice, shame on me. Fool me over and over, then either I really love you blindly or I am a Republican.
