Hanwha Ocean Co., a South Korean company, has secured approval in principle for an 80,000 cubic meter-class electric-propulsion liquefied hydrogen carrier at Gastech 2024 in Houston, United States. This milestone was achieved at the world's largest gas exhibition. Liquefied hydrogen, with its significant volume reduction and increased efficiency in transportation, is gaining traction for storage and shipping. The carrier in question utilizes boil-off gas from its cargo tanks to produce electricity, serving as a zero-carbon power source and emitting no carbon dioxide. As the maritime transport of liquefied hydrogen is predicted to rise, there is a growing demand for large carriers. To address this need, Hanwha Ocean, in collaboration with US-based CB&I and DNV, entered into a tripartite agreement focusing on research related to the design, performance, safety, cargo handling system, and eco-friendly electric propulsion system using hydrogen fuel cells for liquefied hydrogen carriers. This development represents a significant step towards sustainable and efficient transportation solutions in the gas industry.
