Abstract

Abstract The United States’ ambitious greenhouse gas (GHG) emission reduction goals, along with targets set by the International Maritime Organization, create an opportunity to explore battery-electric options for the shipping sector. In this study, we generate a life cycle model of costs and GHG emissions from shipping electrification. We estimate that electrifying 6,323 domestic ships under 1,000 gross tonnage would reduce U.S. domestic maritime sector GHG emissions by up to 75% by 2035 from 2022 levels. By 2035, electrifying up to 85% of these 6,323 ships will become cost effective versus internal combustion ships if they cover 99% of historical trips and charge from a deeply decarbonized grid. We also find that charging demands from electrifying these ships will be concentrated at just 20 of 150 major ports nationwide. Further research is recommended to identify optimal locations based on vessel needs and local grid emissions.
