Vessel owners in the shipping industry are increasingly turning to hydrogen fuel cells and dual-fuel engines to test innovative technologies for reducing emissions and moving towards zero-emissions shipping. Maris Fiducia is at the forefront by preparing to test hydrogen-powered propulsion on a fleet of ships, with a focus on emission reduction and infrastructure development. MSC Cruises is actively piloting fuel cells on their latest vessels, showcasing a commitment to efficient technology adoption. AP Møller-Maersk is also exploring fuel-cell technology for decarbonization efforts, with plans to test PEM fuel cells on their container ships. Additionally, other sectors such as fish transport and training vessels are incorporating hydrogen fuel cells for zero-emissions sailing. Projects like Napier's hydrogen-fueled fish transport vessels and Skulebas' hydrogen-powered fishing vessel demonstrate the industry's shift towards sustainable marine technology. The Maritime Hybrid, Electric & Hydrogen Fuel Cell Conference in Bergen, Norway, serves as a platform for discussing key trends and developments in zero-emissions ecosystems, highlighting the industry's growing interest in hydrogen technology.
