A landmark moment in maritime transport is unfolding in San Francisco with the official launch of the Sea Change, the United States' first hydrogen-powered ferry. This innovative project, supported by CARB and operated by San Francisco Bay Ferry, represents a significant step towards sustainable and environmentally friendly transportation. The Sea Change, powered by a hydrogen fuel cell powerplant, emits only water vapor, with a portion of it even being repurposed for the passenger compartment's drinking fountain. This exceptional vessel, accommodating 75 passengers and cruising at 16 knots, will serve the San Francisco Bay Ferry network, connecting multiple key locations. With renowned sponsors and stakeholders backing this initiative, the Sea Change symbolizes a collective effort towards cleaner and greener maritime operations. Despite facing delays due to the pandemic, the ferry has now obtained the necessary approvals from the U.S. Coast Guard. Looking ahead, the public will have a say in determining the future of this groundbreaking project, as Switch Maritime initiates a petition for continued operation post the trial period. The Sea Change sets a pioneering example of integrating hydrogen technology into marine transportation, fostering a more sustainable future for the industry.
