This paper evaluates the effect of a large-capacity electrical energy storage, e.g., Li-ion battery, on optimal sailing routes, speeds, fuel choice, and emission abatement technology selection. Despite rapid cost reduction performance improvement, current chemistries are infeasible for providing total demand ocean-crossing ships because density is up to two orders magnitude less than in liquid ...
