ALAMEDA– Bay Ship and Yacht Co. has won a contract to build the first hydrogen fuel cell passenger vessel in the nation for Golden Gate Zero Emission Marine, a Bay Area company working to eliminate maritime pollution.

The 70-foot, all-aluminum vessel is expected to be in service by September 2019 and will operate on San Francisco Bay as part of the Red and White Fleet.

Golden Gate Zero Emission Marine secured the $3 million grant to build the vessel from the California Air Resources Board.

The boat will be named “Water-Go-Round,” a nod to how the technology that will power it will work: Hydrogen will be created from water, and after being used in a fuel cell, will become water again.

The vessel will have dual electrical motors and a system that will contain enough hydrogen to go up to two days between refueling.

Alameda-based Bay Ship and Yacht offers a variety of maritime services, including structural repair to vessels. The company was founded in 1977.
