Glosten's innovative hydrogen-hybrid research vessel design for the US San Diego's Coastal-Class Research Vessel (CCRV) has been awarded Approval in Principle by the American Bureau of Shipping (ABS). This project, in collaboration with Siemens Energy, aims to provide a fuel cell-powered vessel to Scripps Institution of Oceanography for studying the marine ecosystem along the California coast. Prior to the AiP submission, a risk assessment workshop involving various stakeholders was completed. The design process includes considerations for liquid hydrogen fuel systems, balancing modern research vessel requirements with evolving regulations. Scripps plans to utilize the CCRV to facilitate research and training for scientists, leaders, and policymakers. The project team is currently advancing the vessel design to a functional level and assisting Scripps with soliciting proposals for construction. The focus lies on creating a research vessel that fulfills scientific needs while emphasizing environmental sustainability. By incorporating novel technologies like liquid hydrogen fuel, Glosten and partners aim to demonstrate a vessel that minimizes its impact on the environment.
