French company Green Navy officially is presenting Europe’s first electro-hydrogen catamaran for commercial passenger and cargo activities, Prometeo, at the Monaco Sustainable & Smart Marina Rendezvous 2023 event (September 24 and 25).
Green Navy is collaborating with governments, research institutions and industry partners to showcase the advantages of hydrogen storage and fuel cell development across a range of marine applications, from regular island hopping to growing eco-tourism.
Green Navy claims to be the first company in Europe to implement this technology on board a passenger catamaran. In addition, the vessel will also be supplied with green hydrogen to ensure a complete carbon-free chain. Green Navy has also developed a transmission system with an optimized gearbox that develops greater torque at reduced speed, improving efficiency and making it easier for the crew to operate.
“Our team of engineers has reengineered the propulsion system and the vessel architecture to reduce mass and optimize energy efficiency” said Charles Cardi, CEO of Green Navy. “Green Navy offers adaptable, efficient and environmentally friendly solutions for operators to buy or lease. Prometeo is carbon-free, silent, vibration-free, odor-free, and easily maneuverable – which makes it a pleasure for crews and passengers alike.”
Production of Prometeo is already underway at Merré shipyard in Nort-sur-Erdre and transportation of the passenger catamaran’s twin hulls to the Merré shipyard in Brest is scheduled for spring 2024. The launch ceremony for this globally important vessel will take place in spring 2025.
“Our commitment to efficiency has seen us work closely with G-Sea Design on the ultimate precision of structural calculations,” Cardi continued. “This has resulted in a lightweight catamaran with exceptional strength and rigidity – tested in all weather conditions and in passenger/cargo/ and combined configurations.
“We have a clean technology vessel that is carbon-free with low energy consumption, offers full marine capacity, is made in France and available at short notice.
“Our electro-hydrogen solution is adaptable to every operator’s budget. Any size of craft can be built with a carefully calculated and optimized weight/performance ratio that dictates the number of batteries and hydrogen bottles required.”
