Scripps Institution of Oceanography at UC San Diego has initiated a project to construct a hydrogen-fuelled coastal class research vessel. This innovative vessel will be powered by a combination of hydrogen fuel cell systems and diesel/electric engines, making it a hybrid model that aims to enhance energy efficiency and reduce emissions. The research vessel is planned to use liquid hydrogen fuel for the majority of its voyage, targeting a 75% reduction in emissions compared to traditional vessels. By utilizing hydrogen, the vessel will operate with zero emissions, providing a quiet profile ideal for contamination-free sampling and enhancing the performance of its underwater acoustic sensors. The design of the vessel has already received approval from the American Bureau of Shipping and has been cleared by the US Coast Guard, indicating compliance with relevant safety and regulatory standards. Interested shipyards have been invited to submit their proposals for constructing the vessel, with a final selection expected to be made by June 20, 2025. The project funding comes from a collaboration between the State of California, the US Office of Naval Research, and the Department of Energy, reflecting a collective effort to support environmentally sustainable initiatives in marine research. The research vessel is planned to conduct scientific missions in the eastern Pacific region, further emphasizing its role in advancing marine science and environmental research. This initiative showcases a positive step towards integrating hydrogen technology in maritime operations and promoting a cleaner and more sustainable approach to marine research and exploration.
