It would be cool to pull charge off the batteries to power the ship.

I estimate that all those batteries would get that ship at most 20% of the way across the Pacific.

The ship runs on LNG, which is probably cleaner than charging the cars in China and using that for energy, given China's grid mix.

It seems to already use some batteries, but not sure for what:

“the new ship includes BYD box-type battery packs and shaft-belt generators for the first time”
