Dude awesome. I mean you gotta hand it to them. Killing it with affordable electric cars, solar panels and now this. It’s a step in the right direction, and that’s more than you could say about UK

Oi lad, shut up and eat yer coal!
We’re putting in tones of wind power. The problem is the weird linking of electricity prices to gas prices and the fact we don’t have anywhere near the energy storage capacity we need. So we end up paying wind farm operators to shut down turbines and generate less when its extra windy.
That battery isn’t all that big…. Oh wait that’s a capitalized M!
Still doesn’t really seem all that big. Some EVs have 100 KWh batteries. A container ship with the battery capacity of 500 cars doesn’t sound like much.
Ships are much more efficient than cars. Having said that, this wouldn’t have a huge range, nor is it terribly big by container ship standards.
Yep, and the Chevy Silverado EV manages 200kWh now. This cargo ship better be small and efficient because 250 American pickup trucks worth of battery really isn’t much.
360 km or 194 nautic miles is the inter-port distance.
Why not an electric train? There is contiguous land between the two cities, and then you don’t have to carry your fuel with you or build giant batteries out of rare earth minerals, while risking run-away shorts that will surely endanger everyone on board, and ensure the cargo is lost.
Plus the distance is <300kms.
Probably because trains are limited in both weight and volume compared to ships and also less efficient. If you have this short route and know it’ll need this amount of cargo shipped it likely makes sense.
This single ship can carry more containers than any train could be expected to pull, likely by at least one order of magnitude.
All in all I’d guess the advantages are roughly:
- Reduced staff
- reduced energy use (land based shipping is less efficient almost by default)
- no need for infrastructure except ports (if you assume there is no train line or this shipping would move existing lines over capacity building this ship is likely cheaper or at least in line with 300km of rail)
- simpler logistics (loading / unloading)
Disadvantages:
- Speed (a train would likely move at 3-5x the speed)
I would also not expect the risk for catastrophic fires to be all that high. This ship has the batteries be containers. So once you’ve designed a container that is a large battery, you’ve already spent so much that a proper BMS including proper battery fire suppression as well as proper breakers/contractors are things you’ve built into it without even thinking about cost. The separation provided by building containers as the battery is the next line of defence if one container fails spectacularly, it also allows the batteries to be maintained on land, much cheaper than if they were part of the ship.
I expect they are using LFP which isn’t fire prone.
Fortunately energy density is not nearly the concern with boats and trains as it is with cars.
And agreed, the modular batteries are a nice touch.
if only we had some kind of wind powered boat technology.
Well there is a reason we stopped using those.
If only we could get energy to trains easily and continuously.
Why make trains when we have horses
I don’t think you could sustain an electric ship with solar panels, but I wonder if you could appreciably extend the range of this ship by adding solar panels.
Hell, if panels get cheap enough you could slap panels on top of all the battery modules. If they happen to be covered by something else, so be it.

By that logic most of the world is helping Russia fuck Ukraine, because they’re also still trading with Russia. Even the US and Europe still are, despite the sanctions they’ve imposed on themselves.
go home lib
Thoughtful contribution that really explained your position while repudiating theirs. I can tell you’ve thought deeply about your position.
you too can go home debate bro
I am home, and saying literally anything besides an insult isn’t “debate”. Are you just afraid of actual discussion? Why are you saying anything at all?
I’m not afraid of actual discussion, and I’ve had plenty of long discussions on this subject here. That’s how I know that discussion with the likes of you is just a waste of my time. And I could ask you the same question.
Honestly I looked at your comments and they’re all just aggressive, and I was genuinely wondering why. You’re not trying to share info, and you’re not trying to convince anyone of anything. What’s the point? Is this helpful to you? It just seems like you’re upsetting yourself.
EDIT: Actually, I take that back partially. You are sharing links. On my mobile app I only saw your comments, not your posts.
No idea why you claim I’m upset about anything, seems that you may be projecting here. You certainly seem upset about my original comment you replied to.
