Experience from ammonia, liquid hydrogen and compressed hydrogen fuel cell vessels

The journey towards decarbonisation is challenging for the maritime industry. Several different energy carriers and fuels are considered and evaluated. Battery is a wise choice in many applications but has its limitations. Therefore, both combustion engines and fuel cells are alternatives. These must be piloted with different fuels for further evaluation, learning and development. SEAM will, in this presentation, share experience from several maritime projects with fuel cell electrification and integration. The experience stretches from initial concept design and approval processes, until several months of duty with vessel operation in normal sailing conditions. Projects include both liquid and compressed hydrogen, as well as ammonia as hydrogen storage.
