Abstract

Shipping Green House Gas (GHG) emissions could increase significantly in the future, and hydrogen fuel for ships could theoretically lower the operational carbon dioxide emissions of a ship to zero. In addition the hydrogen and fuel cell combination could have a higher efficiency compared to the current marine diesel engines. This paper examines the implications of using hydrogen as a fuel for ships. Two hydrogen storage methods, 350 bar compressed hydrogen gas tanks and cryogenic liquid hydrogen tanks, are evaluated in terms of cargo, volume and mass impact in comparison with a conventional HFO tank and a LNG tank. Moreover, the potential loss of cargo capacity for each of them are estimated in relation with the desired range and power. A Panamax container ship was used as a reference ship, in order to visually examine the impact of different fuel storage choices on cargo. A further method has been applied to estimate the relative loss of cargo capacity. It was found that Hydrogen storage systems have a high volume requirement which has implications for both stability and available deadweight. Liquid hydrogen has a lower impact on cargo capacity mainly due to its higher volumetric density than the compressed hydrogen tank. Such conclusions, however, are the result of this early work on the study of hydrogen fuelling as so many of other more detailed issues have yet to be addressed.
