    The sun is always up somewhere. I haven’t seen any numbers on the cost to implement compared to alternatives like battery or pumped hydro storage, but in theory, a global power grid with enough transmission capacity could run entirely on solar.

      Well a superconducting loop (even with liquid nitrogen costs/inefficiencies) would enable a global grid with quite minimal energy loses and reduce the amount of energy storage needed to sustain a stable grid even in the face of failures and disruptions.

      The big problem tends to do with harmonization of energy grid standards.

        My understanding was that most long distance transmission is high voltage DC anyway, so the frequency of interconnected grids should be irrelevant in that case

          harmonization of grid standards is more than just frequency (it is mostly policy paperwork and the replacement of non-compliant equipment or the installation of conversion equipment) but you are correct high voltage DC is used for long distance power transmission. There are also details such as who is responsible for paying for what, where things are to be connected and various other bureaucratic details.
