The Sea Change, a hydrogen-powered passenger ferry, named the first commercial passenger ferry powered entirely by hydrogen fuel cells, made its inaugural voyage in San Francisco Bay. The 75-passenger catamaran travels between Downtown San Francisco Ferry Terminal and Pier 41, showcasing hydrogen's potential for lower carbon intensity marine transportation. With the maritime industry contributing significantly to greenhouse gas emissions, hydrogen fuel cells present a new opportunity to reduce carbon emissions in this sector. Fuel cells convert hydrogen and oxygen into electrical energy, emitting only water and heat. The project aims to increase consumer confidence in hydrogen technology and demonstrate its commercial viability. Collaboration between various entities such as Chevron, SWITCH Maritime, and government agencies has been crucial in realizing the Sea Change project. The involvement of organizations like the Golden Gate Bridge, Highway and Transportation District, Blue & Gold Fleet, and United Airlines highlights the collective effort to support hydrogen adoption in maritime operations. The successful operation of the Sea Change not only provides a sustainable transportation option for passengers but also sets an example of how hydrogen can revolutionize marine transportation. The Sea Change project not only offers a practical solution for lower carbon intensity marine operations but also paves the way for future innovations in the maritime industry. With hydrogen fuel cells proving their efficacy on a commercial scale, the project signifies a positive step towards achieving a greener future in maritime transportation.
