Concept of an Electric-Powered Passenger Vessel in Bangladesh

Abstract

In Bangladesh, the current trend in shipbuilding relies on diesel engines for propulsion. Unfortunately, these engines produce a significant amount of CO₂ and greenhouse gas emissions, which is a concern both locally and globally. To find a better solution, it is necessary to design waterborne transportation with electric propulsion. Although electric propulsion requires a larger initial investment, it proves to be more cost-effective in the long run compared to diesel-based systems. Electric propulsion is highly efficient, with an energy efficiency of 85%, more than double that of diesel engines. Moreover, electric propulsion systems are compact and lightweight, allowing for an increased payload capacity. Another advantage of electric propulsion is its potential for automation and further development. However, building sufficient infrastructure for electric vessels requires careful consideration in Bangladesh. To explore the economic feasibility, this study focuses on the design of a conceptual electric vessel for inland routes in Bangladesh, accommodating 100 passengers. A cost analysis is conducted to compare the two propulsion systems. By examining the costs involved, this research aims to provide valuable insights into the viability of electric propulsion in Bangladesh's water transportation sector. The findings of this study will contribute to the ongoing discussions on sustainable transportation solutions, particularly for inland waterways in Bangladesh.
