  They aren’t forms of energy storage on their own. Just like batteries aren’t a source of energy on their own.

    If only we could find some way of storing some wind so we could release it when there’s no natural wind around.

      We could run wind turbines in reverse

  There’s a separate item for batteries on the list.

  You can also store energy from wind and solar in a hydro dam by pumping water.

  Energy can also be stored as Hydrogen, that should also be included on the list as an energy storage method.

  You can’t turn other forms of energy into solar or wind and store it in those forms. In contrast, hydroelectricity can store energy in pumped storage systems where excess electricity is used to move water to higher elevation (exchanging electricity for potential energy).

    yes, and more importantly, normal Hydro plants could be updated to release water at selected times, to create “on-demand power”. The energy is stored in the water behind the dam. So conventional, already-existing hydro dams can perform a two-sided function: Storing water, and to release it on-demand. Like a battery that is refilled by nature.

      AFAIK, that’s exactly what storage power plants do …wikipedia.org/…/Pumped-storage_hydroelectricity
