Battery-powered electric ferry service to connect Spain and Morocco
- HPsquared 2y agoThose will need some major fire protection. I wonder what the engineering features look like.
- pinkgolem 2y agoLFP is no worse then wood and a lot better then an gasoline fire

- jeffrallen 2y agoThe problem with fighting electric battery fires is finding enough water to cool them. Where oh where could a ferry find vast quantities of water? :)
- mystified5016 2y agoOutside the boat. You need power to get water into the boat, which poses a problem when your power generator is on fire
- wakawaka28 2y agoBattery fires are generally toxic and unextinguishable. That is the real problem. The pollution of water and air is too often overlooked when it comes to these fires, and the health risks associated with that very toxic crap are not well-understood.
- thebruce87m 2y agoAnybody talking about “battery fires” without specifying the chemistry is just showing their ignorance. There are multiple different chemistries. Go look up the guy drilling into LFP batteries on YouTube. Edit: https://m.youtube.com/watch?v=D8xNjz73p80 https://m.youtube.com/watch?v=D8xNjz73p80
- HPsquared 2y agoFair, maybe the protection is more of the "preventive" sort. But they haven't published specifics of which chemistry it is, to my knowledge.
- coreyh14444 2y agoCool. The Copenhagen Harbour "Bus" (ferries) are electric and they are super pleasant to ride. No fumes, almost no noise, no spilled oils or fuels. https://en.wikipedia.org/wiki/Copenhagen_Harbour_Buses https://en.wikipedia.org/wiki/Copenhagen_Harbour_Buses
- ChrisMarshallNY 2y agoI remember taking that same run on a hydrofoil, back in the 1960s or '70s.
- Rygian 2y agoPreempting the "why not hydrogen" comments: Always a good time to refer to "The Hydrogen Ladder" (version 5.0 nowadays): https://www.linkedin.com/pulse/hydrogen-ladder-version-50-michael-liebreich https://www.linkedin.com/pulse/hydrogen-ladder-version-50-mi... In this case, the alternative of using hydrogen for the "Local Ferries" use case would be in class F (almost uncompetitive) and the recommended alternative is indeed electric powertrains.
- gwbas1c 2y agoI came across an article about a hydrogen ferry a month or so ago. I think the ferry was somewhere in northwestern Europe, perhaps on the Nordic peninsula. One major problem is that, due to physics, hydrogen containers leak... a lot. The hydrogen losses from transporting and storing the hydrogen for the ferry were phenomenal. I guess it's impossible to truly seal hydrogen via a valve because it's molecule is so tiny that it can wiggle through the best valves we can make.
- walrus01 2y agoLeakage and hydrogen tank pressures, filling systems are why I think consumers should never own hydrogen fuel cell cars. Ever seen how many people manage to fill their gas car with diesel or vice versa? How careless people can be filling gasoline into approved 5 gallon cans? The number of people driving off from gas stations with the nozzle and hose still stuck in their cars? And now people want to give the average driver access to hydrogen refueling apparatus? Shocking.
- gwbas1c 2y ago> The number of people driving off from gas stations with the nozzle and hose still stuck in their cars? I've never seen that happen. But, I can't seem to fill a gas can without a drip getting on the side.
- walrus01 2y agoIt happens often enough that gas pump hoses are made with a special breakaway mechanism...
- baq 2y agoThere's an electric ferry service between Iceland and Vestmannaeyjar - it's very nice. Quiet and doesn't smell of ship diesel. The charging port and plug are quite something, too.
- jeffrallen 2y agoIf it stays docked on one side at night hooked to the grid and offering grid stabilization services and charges on the other, could it be a net energy importer? Asking for a friend... :)
- zwieback 2y agoThat's very cool. In Oregon we have an electric ferry across the Willamette but it has overhead power lines, like a train.
- seanalltogether 2y agoI wonder how well a flywheel would work in this type of application. Journeys are short, presumably the flywheel can charge up faster then a normal battery. Maybe it's just too dangerous to put on a boat with passengers.
- madphilosopher 2y agoA flywheel has a lot of angular momentum. Of course, that's the point. On buses, the axis of the flywheel is oriented in the vertical axis so that the bus can turn corners or change horizontal directions without causing gyroscopic precession. But on a ship that pitches and rolls, the external force on the flywheel will cause a torque that changes the direction of the angular momentum of the flywheel. A roll would do something like pitch the ship forward or backward (depending on the direction that the flywheel spins), which would really mess up the ship's motion, I imagine. The preceding is just my thought experiment on what would happen to such a ship. Let's build one!

- precommunicator 2y agoA lot of ferries in Norway are electrical like that.
