    All transport going electric, besides rockets, is Elon's goal. We just got one step closer. Article is new but apparently the ferry's been in use for a few months now.

    (I don't know where this belongs on TMC, but I'm sure many investors will be as excited as I am seeing this :smile:, feel free to move it moderators.)

    So 150 kwh for a crossing and a 10 minute fast charge. Is that a 900kw supercharger they have?

    This is so cool. Note that in addition to 1000kWh of on-board batteries the ferry operator has installed 350kWh stationary battery banks on each pier, because there wasn't enough instantaneous power available to re-charge the ferry's on-board batteries sufficiently in the 10-minute docking window specified in their service contract.

    One of the articles I linked to says they could charge 200 kWh at each landing and the effective charge time is around 9.5 minutes. That suggests the charger is around 1250 kW (or 1.25C).

    And one interesting fact is that of the list of promising crossings for electrification, this particular crossing came 23rd out of 40, due to the weak grid.

    Everyone is expecting this ferry to be the first of many.

    Electric crewless cargo ships have also been proposed:

    This ship is zero emission and doesn't have any people on board

    It's also interesting to note that in order to keep to the schedule, it's almost more important to get the ferry 'plugged in' and charging than it is to start off-loading the cars.

    Hmm. I thought Bjørn went on a small battery-powered ferry in one of his Tesla videos. Admittedly, it was just to cross a river, but IIRC, it was battery-powered and it ferried him across.

    Recently went on a small tourist lake cruise in the Black Forest (Titisee) and was surprised the boat (for 125 people) was so quiet and no exhaust - sure enought, when I asked it was electric. The captain didn´t know anything about the battery tech, but he said they only have to charge at night for multiple trips during the day (half an hour each). Bootsbetrieb Schweizer in Titisee im Schwarzwald

    Reading the web site, they have had the boat since 1972. But technically, no ferry ;).

    Also not quite a ferry but a shuttle-boat:
    M/S Sjövägen won Stockholm Regional Coucil's Environment Prize this week as "an innovation applicable within several branches of activities and contributing to reaching the Regional Council's environmental goals".
    Sjövägen


    Carries 150 persons, 25 bicycles, 5 prams and 5 wheelchairs across Stockholm's inner waters. Regular bus/train cards are valid. Runs silently on two 125 kW electric motors and a 500 kWh battery pack, powered by 100% green electricity. Hull is optimized for low swell and good ice performance. Sjövägen is a welcome relief to public transportation while the hub Slussen is being rebuilt over the next decade or so.

    One of the landing docks, Dalénum, came a bit loose last week, temporarily disrupting traffication, but that's got nothing to do with the boat as such. :rolleyes:
