To study the feasibility of hydrogen and ammonia as marine fuels, this research analyses their costs and benefits. While both fuels offer long-term decarbonization potential, adoption faces challenges due to high capital investments and operational costs. Green hydrogen is the most expensive, followed by green ammonia, blue hydrogen, and blue ammonia, though green alternatives have minimal emissions costs. This highlights the need for Market-Based Measures (MBMs) to support their implementation.
