Decarbonizing shipping

Solar power for cargo ships?:

I can see that solar panels permanently installed on/above the top deck of PCTCs,
But portable solar panel on deck/hatches on ordinary cargo ships, (even "stackable) I don’t see as feasible for these reasons:

  • Salt spray will soon cover the panels and need to be cleaned to function optimally.
  • Having to remove the panels for deck cargo (and possibly for some cargo operations)
  • With the small crews on short sea ships today, who is going to do the above?
