I 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.
