Preface On October 11, 2019, an explosion rocked passenger ferry Ytterøyningen while dockside at Sydnes, Norway. The vessel, recently refit with a lithium-ion battery hybrid drive, is part of the new fleet of low and zero emission vessels being deployed across Norway and other parts of the world. The vessel was at dock having been pulled from service the night before due to a fire in the lithium propulsion batteries; a condition known as thermal runaway. The root cause of the fire is still to be announced, but the secondary explosion caused significant structural damage to the vessel; likely a result of a buildup of flammable gasses below deck. Thankfully none of the 15 people admitted to the hospital were badly injured and all were soon released.

electricity, salt water... what could go wrong?
“electricity, salt water... what could go wrong?”
That’s been around forever, or at least decades. The new factor is LITHIUM batteries.
There have been problems with all sorts of ship engines.
Yes, there will be problems here also. Who knew?
Over time the problems will become fewer and fewer.
Any new tech has growing pains.

Similar to the reason Uncle Fester could not be an astronaut.
I read an article about that fire, and later I was looking for a cruise to go on. One of them was on a ‘green’ ship, which means it had batteries...passed up that opportunity.
And I’m still having trouble understanding just how large battery banks are supposed to help a cruise ship save energy. I can understand cars, trucks, and other vehicle that are in stop-and-go traffic and thus can use regenerative braking to recover some of the energy associated with stopping, and yes, eventually even cruise ships stop and maybe use reverse thrust once in a while (such as in port) ...but how, exactly, would they regenerate energy and if they did, the amount would be tiny, relative to traveling hundreds of miles through ocean?
It seems to me to be more of a gimmick than even replacing buses with trains.
Smug is explosive. Who knew?
With a ‘hybrid’ car there is value in capturing energy during braking and using it for future propulsion. The worse at driving a person is the more helpful such technology is (e.g. people who don’t anticipate that they will have to stop at the red light ahead and slam on the brakes at the last minute rather than coast and slow down.)
What value is this on a ship which would stop using its drag or with engines in reverse?
This ship was a passenger ferry, which I assume travels a short distance, stops at the dock, and then goes back. While at the dock, batteries could be recharged.
Hybrid ship. Is that like hermaphrodite brig?
Amazing Tales Of The Harbor.
I’m a watchmaker and won’t allow LITHIUM batteries into my shop!!!! Most batteries can be saved for re-cycling but a box of “dead” LITHIUM batteries, packed for mailing by a store I serviced, overheated on a counter and started a very hot fire.
When it blew, a fire started on the store’s carpet.
When the battery “dies” it is NOT dead. It merely lacks the voltage to do its job. When improperly collected, the voltage increases times the number of batteries.
The U.S. Post Office won’t accept packages containing them.
Maybe it’s best to take the hint.
I guess...but I did actually hear of a cruise ship with that garbage.
Anyway, I guess the people who build ships need to learn the SAME LESSON that everyone learns the hard way, which is that Lithium Batteries are not toys and are not forgiving. They were just very lucky not to fry a boatload of people.
In other news, importing large numbers of Islamic fascists into your country causes significant thermal runway.
“Im a watchmaker and wont allow LITHIUM batteries into my shop!!!! “
Do you frisk for cellphones?
Can’t they just use Big Sails instead??
Just a matter of time.
“One of them was on a green ship, which means it had batteries...passed up that opportunity.”
Probably an LNG.
Not my line of work, but methinks this is close to perpetual motion?
Here it is:
And your tax dollars at work!
The dockside solar will be facilitated by the US Army Corps of Engineers at their Bay Model facility, which has recently been outfitted with a rooftop solar array that generates 540 kW/h
I wouldn’t be too crazy riding along with several thousand tons of LNG either...gets nasty if the power goes out.
