All-Electric Cargo Ships Data Analysis and Efficiency vs Fuel Ships Comparison

This paper scrutinizes the common belief that electric vessels are economically unadvantageous. To achieve this, data of most known all-electric cargo ships (available in internet as 2021) was gathered and missing information estimated with due diligence, to put together a sample selection. Sample vessels’ parameters including principal dimensions, speed battery capacity were used calculate their relative transport efficiency. Different routes speeds used, efficiency compared fuel-powered vessels. Electric shown be about 50% more profitable on short equally medium (if they slow steaming), reasons being reduced crew, lower maintenance requirements higher propulsion However, at long and/or high oil-powered currently dominate because otherwise big part space would allocated transporting batteries, whose energy density is much than fuel among other reasons. derives design guidelines helps make an informed decision whether use ship given route.
