San Francisco Bay is now home to the world's first hydrogen-powered commercial ferry, named Sea Change. This innovative vessel, managed by investment firm SWITCH Maritime, aims to revolutionize passenger transportation on the bay. The ferry, built at the Bay Ship and Yacht in Alameda and All-American Marine in Bellingham, Washington, operates with water vapor as its only byproduct, significantly reducing carbon emissions compared to traditional diesel-fueled boats. As part of a pilot program, Sea Change offers free rides to passengers for its first six months, promoting eco-friendly and sustainable travel. With the ability to carry up to 75 passengers and travel up to 300 nautical miles on a single refuel, the ferry presents a promising solution for clean maritime transportation. The hydrogen fuel cells on Sea Change generate electricity by combining oxygen and hydrogen, offering a glimpse into a cleaner and more sustainable future for the maritime industry. The successful launch of this hydrogen-powered ferry in San Francisco opens the door for potential expansion of similar eco-friendly transportation solutions worldwide, showcasing the growing importance of renewable energy in public transportation.
