Techno-economic investigation of alternative propulsion systems for tugboats

In this paper, the main alternative propulsion systems based on internal combustion engines and batteries of a tugboat operating in harbour duties of the tugboat that include Emission Control areas are comparatively assessed. A hybrid propulsion system and two gas systems that one is with gas engine...
