The American Bureau of Shipping has approved the preliminary design of a groundbreaking hydrogen-hybrid research vessel, the California Coastal Research Vessel (CCRV), to be operated by Scripps Institution of Oceanography in San Diego. This first-of-its-kind vessel will utilize a hydrogen fuel cell propulsion system, enabling zero-emission operation for a significant portion of its missions. While additional power for longer missions will come from modern diesel generators, the emphasis on hydrogen aims to reduce greenhouse gas emissions and support California's climate action goals. The CCRV is tailored for a wide range of research missions, from studying fisheries to investigating climate change-related phenomena like El Niño storms and ocean acidification. By providing crucial data to protect California's coastal environment, the vessel will showcase hydrogen's role in achieving a carbon-neutral economy. Furthermore, the ship will serve as a vital training platform for students, aligning with UC San Diego's commitment to hands-on education. In addition to its environmental significance, the CCRV's development required creating a new regulatory framework for liquid hydrogen-powered ships in the US. The project, supported by a $35 million allocation from California state legislators, signifies a major step towards wider adoption of hydrogen as a marine fuel. Through collaboration with regulatory bodies and innovative engineering, the vessel's design successfully integrates cutting-edge technology with safety standards. Governor Gavin Newsom's visit to the Nimitz Marine Facility in March 2023 highlights the state's involvement and support for the vessel's innovative approach. With a positive sentiment towards hydrogen and environmental sustainability, the CCRV represents a significant advancement in marine technology while nurturing the next generation of ocean scientists and leaders.
