World's first hydrogen-powered, zero-emission cruise ship floats out

The Viking Libra, recently floated out at the Ancona Shipyard in Italy, is the world’s first hydrogen-powered cruise ship, marking a significant milestone in sustainable maritime transport. Weighing 54,300 tons and equipped with 499 staterooms to host 998 guests, the ship uses a propulsion system partially based on liquefied hydrogen and fuel cells, generating six megawatts of power. This technology enables zero-emission operation, producing only water as a byproduct, and allows navigation in environmentally sensitive areas. Viking partnered with Italian shipbuilder Fincantieri and its subsidiary Isotta Fraschini Motori to develop the advanced fuel cell system, emphasizing a commitment to reducing fuel consumption and environmental impact. Despite this breakthrough, challenges remain in ensuring the cruise ship’s hydrogen fuel is truly eco-friendly. Most industrial hydrogen production currently relies on steam methane reforming, which emits CO2, undermining the zero-emission promise. Green hydrogen, produced via electrolysis powered by renewable
