Hydrogen bunkering from a fuel island onto fishing vessels

Decarbonizing the fishing and aquaculture sector is an important goal for Norway as well as for the global shipping trade. Hydrogen is potentially a good fit for the energy demand of fishing vessels. For the fleet to switch to hydrogen as primary fuel, solutions for ensuring sufficient energy onboard must be found. One such solution could be to bunker the hydrogen at sea, in locations closer to the areas of operation of a fishing fleet. In the present work, we have investigated the bunkering of 250 bar gaseous hydrogen onto fishing vessels that require 4000 kWh of energy onboard. The first part focuses on the bunkering of a single vessel and an analysis of the technical parameters that affect and constrain the hydrogen bunkering rate. The second part focuses on the bunkering of several fishing vessels from a hydrogen refuelling station located offshore. • Reduction of emissions from fishing and agriculture will most likely include hydrogen. • Dynamic model of gaseous hydrogen bunkering onto fishing vessels developed. • High bunkering rates makes the temperature in the onboard tanks to exceed the limit. • Comparison of bunkering station capacity with and without compressors are presented.
