San Francisco has taken a significant step towards sustainable maritime transport with the launch of Sea Change, the world's first commercial hydrogen ferry. Developed by Switch Maritime and supported by various partners, including a grant from the California Air Resources Board, Sea Change aims to revolutionize the ferry industry's approach to emissions. The vessel, powered by hydrogen fuel cells, eliminates direct carbon dioxide and toxic air pollution, setting a new standard for clean energy in public transportation. The launch of Sea Change comes as ferry operators globally face pressure to transition to zero-emission fleets. Despite challenges in procuring green hydrogen, Switch Maritime is committed to exploring sustainable production methods. With a six-month pilot service planned and support from government and private entities, Sea Change represents a significant milestone in the journey towards decarbonizing maritime transport.
