Maritime transportation is often considered a ‘hard to abate’ sector, meaning it is difficult to reduce its greenhouse gas emissions. Using high-resolution data on ship activity, a techno-economic analysis indicates that electrifying US domestic ships of lower than 1,000 gross tonnage to reduce emissions could become cost effective, if a small percentage of long trips are excluded.

美国海上运输电池潜力的大规模估计


海上运输通常被认为是一个“难以减排”的行业，这意味着很难减少其温室气体排放。一项技术经济分析使用有关船舶活动的高分辨率数据表明，如果排除一小部分长途旅行，那么对低于 1,000 总吨位的美国国内船舶进行电气化以减少排放可能会变得具有成本效益。
