    Still doesn’t really seem all that big. Some EVs have 100 KWh batteries. A container ship with the battery capacity of 500 cars doesn’t sound like much.

      Until you realize that the energy requirement is also different. Land transport in general is very inefficient. Ship is in fact one of the most energy efficient means of transport.

        I don’t disagree but every time I’ve seen a diesel engine on a cargo ship it was absolutely massive.

          Size wise, it is small relative to the ship size. Look at car engine. How many % of volume is taken up for the engine and fuel tank of car? I think it is close to 30-40%

        194 nautical miles isn’t terribly far, though. For port to port, sure. For oceanic shipping, I don’t think 194 is going to cut it. I think we will probably have to do SMRs or efuels to really cut cargo ship and cruise ship emissions when crossing the Pacific or Atlantic. Though I don’t know where nuclear powered shipping (in non-military applications) is in terms of progress.

          I do think that cargo ships are the one vehicle where solar panels would make sense though. Add that and a sail, and you should be able to increase the range considerably.

      Ships are much more efficient than cars. Having said that, this wouldn’t have a huge range, nor is it terribly big by container ship standards.

      Yep, and the Chevy Silverado EV manages 200kWh now. This cargo ship better be small and efficient because 250 American pickup trucks worth of battery really isn’t much.
