  •  The study already assumes massive power storage (1+ / 0-)

    They assume storage power capacity totaling about 20% of total power generating capacity, providing about 2.5% of total energy.

    They're modeling a mix of hydrogen  in high-pressure tanks, Li-titanate batteries, and GIV (grid-integrated vehicles). That is a lot of storage, but is a lot less than I have ever assumed.

    This is an impressive paper; they did some good work.

    •  Umm, that's missing the point (1+ / 0-)

      Liquid metal batteries are meant to be put at the exit of any and all solar/wind installations not just to provide energy when the sun isn't shining or the wind isn't blowing, but rather to provide a smooth energy output to the grid.

      It isn't just the erratic delivery that's a problem for these electricity sources. It's the erratic intensity of the energy. These batteries solve both delivery and intensity concerns which it sounds like this paper isn't accounting for. Not having read the paper, I can't say that for sure though.
