5th International Hydrogen Technologies Congress, 26 - 28 May 2021
Maritime transportation is under the pressure of reducing greenhouse gas emissions from ships. The rule-maker of the maritime industry, International Maritime Organization tightens the bond around ships to eliminate harmful exhaust emissions due to environmental concerns. Considering chemical properties, the use of hydrogen in ships may be a solution through zero-emission shipping. In this study, onboard hydrogen storage methods are reviewed and compared for ships. Obstacles in front of the industry are revealed and required changes are highlighted. Bunkering and storage infrastructure, global availability of hydrogen fuel, and safety issues for reliable operations seem like the biggest challenges at the first step of the industry.
