Abstract: The call for concerted global action against the climate change impact is well heard. 191 countries would communicate their progressive plans through Nationally Determined Contributions (NDC) to the United Nations Framework Convention on Climate Change (UNFCCC) as signatories to the Paris Agreement. Harbour crafts as part of the larger maritime ecosystem, can significantly contribute to reduced emissions. In this paper, HyForce, the next generation 2 MW hydrogen powered virtual tugboat was designed for a feasibility assessment for her techno-economic and environmental footprint to replace existing diesel-powered tugboats. The study compares the use of hydrogen fuel cells and an internal combustion engine to perform the same dynamic load profile for a typical tugboat mission. The results from the study show that a signpost for commercial competitiveness of HyForce is influenced primarily by the projected liquid hydrogen cost of 5.10 USD per kg in 2040 with a 2,000 USD/kW capital cost for the fuel cells. Greenhouse Gas (GHG) emissions from a “well-to-wake” analysis for fossil-based hydrogen and renewable hydrogen supply chains were conducted, and the results show 26.9% and 75.6% reduction, respectively, compared to similar tug running on diesel fuel.
