Presentation

Comparing batteries and hydrogen for a coastal research vessel

With funding from the Maritime Administration, Glosten worked with Sandia National Labs and Scripps Institution of Oceanography in 2017 to determine the feasibility of an all-hydrogen-fueled coastal research vessel. Though feasible, the vessel exceeded the available budget and was larger than what was immediately needed by Scripps. A follow-on study was recently completed that assessed and compared the technical and economic feasibility of a 125ft battery-hybrid or hydrogen-hybrid coastal research vessel. Following the study, Scripps has recently received US$34m from the State of California to build the hydrogen-hybrid variant.
