Re: Exploring the Cost and Feasibility of Battery-Electric Ships
#2Ferry service in the Puget Sound (Seattle Area) has suffered due to delays with electric ferries. The state refuses to maintain their existing fleet. Every line has frequent delays, and the international route which was suspended for “a couple years” in 2021 is now delayed until 2030.
The frustration people have with electric isn’t the technology – it’s the dogmatic commitment to technology that isn’t quite ready, based on false promises of it solving climate change .

#3Wow, this is a really good paper. Supplementary info is really great too- they get into details down to floating charging port stations as part of the infrastructure. Surprising how much demand is from tugboats. I have questions about how you'd safely hook up 5 MW connections, but it's definitely solvable.

I've traveled on a battery electric ship in Norway, quite a few years ago. It recharged while docked loading passengers using two high voltage high current cables slung from a crane.

#5I support this idea but I stopped reading when the costs factored included the social costs of CO2 emissions. which I'm sure are important, but shipping operates on the actual cost of fuel and equipment, until CO2 tax is in that aren't we just making up economics?
They're also factoring in the value of the batteries second life, which seems at best, speculative.
ships should be electric, they're filthy to be around with 24/7 diesel generators running even on the quayside. if ship electrification prompted better port facilities of shore side hookup just that would be a win.

It looks like that is a conversion and retrofit of ships that were already unmaintainable: https://washingtonstatestandard.com/briefs/conversion-of-was...
Modernizing all the control systems etc is the nightmare. The ferries were already electric- all ferries are; they have diesel engines driving generators which drive electric motors. They still have the exact same generators running the same motors. The batteries are installed and ready even though they won't be used until the port is electrified years from now: https://www.youtube.com/watch?v=hkgT9Z8Z2RU

They split the emissions cost out separately, FWIW: https://www.nature.com/articles/s41560-024-01655-y/figures/3

this? https://www.seattletimes.com/seattle-news/transportation/ele...
interesting they're struggling to get ship builders to bid.
Seems like a lesson learned is to build new boats until service is over capacity before refitting old boats where the unknown unknowns lurk.
