Australia Launches World’s Largest Battery-Electric Ship in Maritime Milestone

But will the batteries be charged from a power grid that is powered by fossil fuel plants?

If so is there really a large benefit?

I don't know so I'm asking.

Searched a bit. Uruguay is high on renewable (lot of hydro power.) but depending on import from Argentine and Brazil is demand exceeds.

Argentine about 39% low carb.

So they could well say this ship is hydro powered

I'd guess that all of the detractors don't power their house with solar or have an EV.

Takes a while for some people to get it.

Why do people hate new technology?

Imagine the blaze when 551,000 lbs of lithium batteries blow up.

As to the advanced electric boat, "Hull 096 features a massive energy storage system with over 275 tons of batteries."

 

AA or AAA?

You've heard of tugs?

7000 miles (*2) with a Diesel fueled tug.

Will need a lot of ferry rides to compensate.

What makes you think a tug would cost any more than the hundreds of bulk carriers criss-crossing the oceans every day?

Imagine what happens when a nuclear reactor gets out of control.

 

There's quite a few of them afloat and below water.

I will love to see that rare occasion. Crude oil blow up can creat quite a blaze and pollution.

Aircraft carriers don't use electricity for propulsion.

 

The heat generated by nuclear fission is use to generate steam, which then goes to a steam turbine, converting thermal energy to kinetic energy. That's what turns the propellers.

 

As far as risk goes, I'll take sitting on 275 tons of batteries over sitting on a nuclear reactor every time. So would most insurance companies.

 

 

 

Correctamundo.

Mostly.

 

In another form of drive system, the turbine turns an electrical generator, and the electric power produced is fed to one or more drive motors for the vessel's propellers. The Russian, U.S. and British navies rely on direct steam turbine propulsion, while French and Chinese ships use the turbine to generate electricity for propulsion (turbo-electric transmission).

 

So the Chinese DON'T steal all our technorogy.

All our leduction gealboxs no berong them.

That's "jumping the shark."

Your original post claimed nuclear reactors onboard aircraft carriers made electricity to power the propellers.

 

Pro tip: When you're in a hole, getting out of it is easier if you stop digging.

 

As China leads the world in nuclear fusion research and high speed trains, and seems to have attained parity or better in AI, I have no problem accepting they are smart people.

Would be interesting to know how they ferry the ferry over the approx 7000 miles.

 

 

I suspect a semi-sub heavy lift vessel for float on/float off (FO/FO)

More plausible.

The ultimate humiliation will come when they have to tow it from Australia to Argentina, where it will be used to cross a river that appears to be about 30 miles wide between Buenos Aires and Uruguay.

 

I wonder if the green press will cover the tow, by a tug or tugs powered with nasty bunker oil.

Why would they? Do they cover tugs powered with nasty bunker oil pulling ships that run on nasty bunker oil? 

What is the life expectancy of this ferry?

If the ship isn't newsworthy, why are we reading about it here?  Because it's an electric, the media is fawning all over it.  Which is why towing it from Aus to B.A. should be covered as well.  But I'll be it won't.
