Stockholm ferry operator Ballerina has placed an order for a lithium-ion battery system from Saft Batteries to provide all electric power for a brand new ferry boat.

The goal is to greatly reduce operating costs and emissions. Not to mention, provide serenely quiet operation.

The all-electric ferry will make 10 stops on a 50-minute route of the Stockholm waterways carrying foot passengers and cyclists.

Batteries are fully charged overnight in the harbor and 2 partial charging sessions occur during the 8 round trips each day.

Saft’s experience in providing lithium-ion battery systems builds up on this order as Saft has already provided battery systems for Bordeaux City with two hybrid battery-and-diesel-powered ferryboats and a 100% battery powered shuttle boat for Paris’s canal Saint-Denis.

Saft’s Sales Manager for the Nordic countries and Germany, Christer Steen, adds:

“Saft is a pioneer in electrically powered vessels, which are growing in popularity and offer the promise of low operating costs, quiet operation and reduced emissions. Saft sees significant potential in this market.”

In order to meet ferry requirements, Saft will be supplying an energy storage system with capacity of 500 kWh, at 650 V.

This all-electric ferry has not been named just yet, but it will begin operations in September 2014.  Saft will deliver the energy storage system by May 2014.

Cool 🙂
I need to try it out when it arives 🙂

That is GREEN stuff

This is a picture of how it looks like:

It’s brilliant to see that the boat industry are picking up on the great environmental improvement that EV’s are.
It’s by far the dirtiest vehicles we have so any improvement there is a big win.
Another thing that has recently been done is that the large ferries (big ass ferries, cruise sizes) can use electricity from the main land to power the ferries when at the harbor. It’s a simple thing to do really but most ferries and harbors let the ferry use it’s own engines to generate the electricity needed even when docked.

(spoiler… Ballerina is a very popular cookie in Sweden and saft means juice/lemonade)

Space rockets are probably dirtier than ships…but I assume Elon Musk will capture an asteroid and build an electric space elevator before he dies (and no, it’s not a joke, if not Elon then at least Elon junior =).

Relative per trip, yes. Absolute numbers, though… rockets aren’t launched often; ships are used continuously around the world.

For once, I think sea vessels should run on hydrogen. It can be made from deep sea windgenerators along which the vessels would pass along their trip to refuel.

This is the reason why SpaceX is developing a methane powered Raptor rocket engine for next generation rockets. As we know, methane is easy to produce from renewable sources.

Also SpaceX is developing the reusability of rockets in order to reduce the ecological footprint of manufacturing rockets. Actually SpaceX demonstrated successfully just few days ago the reusability of first stage.

Therefore as space rockets are hard for the environment, Elon Musk is working hard in order to significantly reduce the ecological burden of rockets.

And can we perhaps harness all that methane from cow flatulence to send men to Mars?

It is also cheaper than RP-1, can be produced on Mars, is readily available here as LNG and it doesn’t clog in the engine heat exchangers so that fits well with reusability.

There was a possibility to use a smes for an electric rocket system but it never took off. So it also never took off literally as well. Nevertheless the physics is still out there and with superconductors available today it actually becomes more feasible. It basically store magnetic energy in a closed loop and a stream of ionized gas, for example a standard rocket plume, is accelerated by the MHD effect on it. The jet multiply its exhaust speed and thus also its trust. In the end only a fraction of the energy comes from combustion and most of the energy comes from the electricity used to charge the smes on the ground. To make it economically viable the rocket must be reusable though otherwise it would be really too expensive to throw away a smes at each flight. Later it should be possible to limit fuel use to space only since atmospheric air can be ionized to serve as MHD propellant for most of the trip.

hmm, i think ships might be greaner than trucks if you look at fuel/kg/km. it is nothing more than a guess so i might be wrong, but it would be interesting to se some noumbers

It googles at 33 g co2/tkm for river ships vs 48 for rail vs 164 for a diesel truck.

When it comes to energy and CO2 then yes. But even though reductions have been made the levels of sulphur is still many many times worse. And as far as I know the levels of NOx are still also way higher per ton per km transported.

The global warming might benefit from it and maybe not kill polar bears sometime in the future. But the Baltic sea is already almost dead and in desperate need of CPR.

I wonder how such a ferry will do when it sinks and high voltage batteries are in the water, potentially with survivors in the water close by.
They should have a fuse to disable the batteries if they become immersed in water.
Without such protection, the batteries could electrocute people in the area in the water.

Dang, the battery’s likely in the $100k-200k range by itself, but presumably the fuel savings will be worth it in short order, even if a conventional analogue burns bunker fuel (which, being a ferry, it probably burns un-road-taxed diesel).

Un-road-taxed diesel?

Diesel fuel is sold and taxed at different rates depending upon what you use it for. Farm and marine diesel are both taxed at different rates than, for example, heating oil despite being exactly the same thing.

Around here you can find heating oil pumps alongside diesel pumps at gas stations, but don’t ever let them catch you putting it into your vehicle!

Dr. Kenneth Noisewater

Typically a dye is introduced to offroad diesel, which mechanics et al. are legally obliged to report if they detect it in your vehicle’s fuel system.

Alternately, you COULD try running a diesel engine on kerosene. It needs additives for lubricity though, and I would bet that it would void the warranty especially on newer common-rail models..

Bunker disel is almost taxed the same as road disel now in sweden
