   No, not with national grids.

   Sure, there are in theory some of those like HongKong,   
   but national grids work fine there too.

   Yep, used extensively for cooling nukes and tide power systems.

   Ships handle it fine.

   Those don’t necessarily have convenient places to pump it up to tho.   
      
   Again, not a problem with national grids tho.

   Sure, not all places like say Holland are suitable.   
      
   But with power links between EU countries that’s less of a problem than it   
   was.
