The California Coastal Research Vessel will revolutionize oceanographic research with its innovative hydrogen fuel cell propulsion system, enabling zero-emissions operation for a significant portion of its missions. Developed by naval architecture firm Glosten and approved by the American Bureau of Shipping, the vessel will play a key role in advancing California's climate action goals by reducing global climate risk and transitioning to a carbon-neutral economy. The ship, dedicated to California research missions, will study various environmental processes to better understand climate change impacts. It will also serve as a vital platform for hands-on learning, training future scientists and leaders while aligning with UC San Diego's educational programs. The project required close collaboration between multiple stakeholders to ensure compliance with evolving regulations and the safe integration of liquid hydrogen technology. With strong governmental support, including funding from California legislators and federal support through the Department of Energy, the California Coastal Research Vessel represents a significant step towards a sustainable maritime industry and a cleaner energy future.
