Naval architecture and marine engineering firm Glosten has secured Approval in Principle (AIP) from the American Bureau of Shipping (ABS) for the design of UC San Diego's next-generation Coastal-Class Research Vessel (CCRV), incorporating a hydrogen-hybrid propulsion system. Operated by Scripps Institution of Oceanography, the CCRV will pioneer the use of hydrogen fuel cells for zero-emissions marine operations, contributing to environmental sustainability. The project navigated complex regulatory challenges to ensure compliance with regulations and safety standards, working closely with regulatory bodies like the United States Coast Guard (USCG) and ABS. The vessel's design signifies a step forward in utilizing hydrogen as a marine fuel, with ABS emphasizing its potential impact on wider hydrogen adoption in the maritime industry. The CCRV will facilitate research on the California coast, running on emissions-free hydrogen for a significant portion of its missions, showcasing the feasibility and benefits of hydrogen-fuel-cell propulsion for coastal vessels. Beyond research, the vessel will play a crucial role in hands-on education, offering valuable seagoing experiences for students and scientists at UC San Diego. By aligning with institutional values for environmental protection and innovation, the CCRV represents a significant advancement in sustainable marine technology.
