Burning ship off Dutch coast has more e-cars than thought - eviltoast

A freight ship that caught fire off the Dutch coast and has been burning since, as fire extinguishers try to figure out ways to tackle the incident, has been carrying nearly 500 electric cars, far more than previously reported, the company that chartered the ship said.

Initial reports said that the ship was carrying 25 electric cars.

The Fremantle Highway vessel, which has burning for a fourth day off the Dutch coast, was chartered by Japanese transportation company K Line.

A spokesperson for the company said there were 3,783 vehicles on board, including 498 battery-electric vehicles. The spokesperson declined to comment on the kinds of car brands that were on the ship.

There is no information on whether the cargo ship was carrying cars by Japanese manufacturers.

Electric car battery fires much harder to put out

The Dutch coast guard said Thursday the cause of the fire was unknown, while Dutch media reported that the fire may have been after an electric car battery ignited.

Cars with lithium ion batteries have fewer fires than diesel and gasoline cars, but the situation can be dangerous when the batteries catch fire.

The fires then are hotter because there’s a lot more fuel inside an electric car battery because the battery cells are densely packed. It also takes a lot more water to put the fire out.

But pouring too much water to douse the flames is also not a tenable solution because there are fears of the ship sinking and environmental havoc.

The 199-meter Fremantle is still drifting in the sea, about 17 kilometers from the Dutch island of Terschelling.

    The main problem with lithium ion battery fires is that the reaction is self-oxidizing, so you can’t put it out by just smothering it. You actually need to cool them down enough so that they don’t re-ignite. Plus, once they’re damaged, even if you do cool them down enough they’re much more likely to short and re-ignite themselves again anyway.

    Consider the “fire triangle” - fire needs three things: fuel, oxygen, and heat. With, for example, gasoline fires you can take away either oxygen OR heat to extinguish them, but with lithium-ion battery fires you have to take away the heat to extinguish them.
