An Overview on Zero-Emission Tugs (or Ships) in the Market

Abstract

Zero-emission vessels are among the promising solutions that might respond to the pressing demand of the global maritime industry to decrease greenhouse gas (GHG) emissions, thereby reducing the environmental deterioration caused by shipping.

Therefore, this study aims to give an overview of the current market situation of zero-emission tugs and ships. To achieve that, this study reviews the recent developments in zero-emission propulsion systems, focusing on hydrogen propulsion systems, battery-electric systems, and hybrid-based technologies. It also covers the regulatory frameworks and incentives that shape the adoption of zero-emission vessels, as well as the economic impact of zero-emission technologies on ports and shipping companies; hence, it gives reasons for challenges and opportunities on the pathway to a sustainable future for the maritime sector.
