The fuel cell ferry project  (SF-BREEZE) examined the technical, regulatory, and economic feasibility of a zero-emission, high-speed passenger ferry powered solely by hydrogen fuel cells and its associated hydrogen fueling infrastructure within the context of the San Francisco Bay. In conjunction with a naval architect, a realistic, feasible vessel design meeting all performance specifications was produced. Collaboration with and evaluation by both the US Coast Guard and the American Bureau of Shipping did not reveal any insurmountable regulatory obstacles to deployment. The supply of liquid hydrogen to the vessel was examined and viable sites were found at the Port of San Francisco and the Port of Redwood City. Industrial gas companies were consulted and provided technically viable fueling facility designs. The current design of the zero emission ferry has a cost premium compared to a conventional diesel ferry. Cost reduction strategies specific to the vessel and leverage of those expected in the fuel cell electric vehicle market may result in future cost parity.
