On: Battery cost declines raise prospects of all-electric container shipping

[Scoundreller]

The idea of the container batteries is that they don't have to be rapid-charged, but having batteries sitting around isn't productive either.

I think the hard part is having 300MW (*#ships) of peaking capacity and the standby costs of when it's not being used.

For reference, Toronto uses about 4500MW on a hot summer day (like today).

Nothing is being rapid charged. You need 24 hours at 300 MW to charge one of these things. Either you use even more than 300 MW, or you have batteries charged many days in advance. Both are nutty ideas.
