Not specifically. Energy storage?

• tcfhgj 4y ago
  The cheapest storage of energy is gas cavernes underground

    This seems extremely constrained by geology, even more than hydro. And what sort of gas would you be storing there?
    • tcfhgj 4y ago
      Hydrogen, methane
  • brutusborn 4y ago
    Again, any sources? I know of some gas storage caverns but they didn't come cheap.
