The European Union is placing a strong emphasis on reducing emissions by utilizing green hydrogen as an alternative fuel in sectors that are difficult to electrify. High-speed ferries in Norway have been evaluated, showing that hydrogen-powered ferries can reduce emissions significantly if produced using renewable energy sources. However, challenges such as hydrogen storage space and energy demand remain. Ammonia is also gaining attention as a potential energy carrier for shipping, with plans for an ammonia production facility in Bremanger, Norway. The project, supported by the EU's Innovation Fund, highlights the scale of energy demand for ammonia production and the need for sustainable energy solutions in the shipping industry. Overall, the transition to green hydrogen and ammonia presents promising opportunities for reducing emissions in the European shipping sector.
