Abstract

The United States’ greenhouse gas (GHG) emissions reduction goals, along with targets set by the International Maritime Organization, create an opportunity for battery electric shipping. In this study, we model life-cycle costs and GHG emissions from shipping electrification, leveraging ship activity datasets from across the United States in 2021. We estimate that retrofitting 6,323 domestic ships under 1,000 gross tonnage to battery electric vessels would reduce US domestic shipping GHG emissions by up to 73% by 2035 from 2022 levels. By 2035, electrifying up to 85% of these ships could become cost effective versus internal combustion engine ships if they cover 99% of annual trips and charge from a deeply decarbonized grid. We find that charging demands from electrifying these ships could be concentrated at just 20 of 150 major ports nationwide. This study demonstrates that retrofitting to battery electric vessels has economic potential and could significantly accelerate GHG emission reductions.

探索电池电动船舶的成本和排放影响、可行性和可扩展性

美国的温室气体（GHG）减排目标以及国际海事组织设定的目标为电池电动航运创造了机遇。在本研究中，我们利用 2021 年全美船舶活动数据集，对航运电气化的生命周期成本和温室气体排放进行了建模。我们估计，将 6,323 艘总吨位在 1,000 吨以下的国内船舶改装为电池电动船，到 2035 年，美国国内航运业的温室气体排放量将比 2022 年的水平最多减少 73%。到 2035 年，与内燃机船舶相比，如果这些船舶的电气化覆盖 99% 的年航程，并通过深度去碳化的电网充电，那么这些船舶中高达 85% 的电气化船舶将具有成本效益。我们发现，在全国 150 个主要港口中，这些船舶电气化后的充电需求可能只集中在 20 个港口。这项研究表明，改装为电池电动船具有经济潜力，并能显著加快温室气体减排速度。
