Suez Canal route to Green Shipping Corridor: A comparative analysis of conventional fuels vs. green hydrogen based E-fuels consumption quantities and emissions for ships transiting the canal

The global intensification of climate impacts places all sectors under increasing pressure to reduce emissions. Achieving climate neutrality requires drastic transformations globally. The climate change targets set by the International Maritime Organization (IMO) demand more than improvements in propulsion efficiency; the amount of fuel consumed, and the resulting emissions remain challenging to be met. Alternative green fuels introduce varying properties in terms of energy density and emissions, making it essential to highlight these differences and establish reliable comparisons to define a clear pathway toward compliance. This study demonstrates the ships fleet transiting the Suez Canal and estimates the emissions resulting from the use of conventional fuels, along with corresponding fuel consumption quantities. It analyzes the potential impact of adopting alternative e-fuels, focusing on changes in fuel consumption and associated Greenhouse gas (GHG) emissions, resulting in emissions reduction of 62% up to 79% across different proposed green hydrogen fuels.
