The world's first hydrogen-powered commercial passenger ferry, the MV Sea Change, is set to sail on San Francisco Bay to combat diesel emissions and reduce carbon footprints. The 70-foot catamaran will operate a free service for six months between Pier 41 and the downtown ferry terminal. The ferry, equipped with fuel cells that produce electricity through hydrogen and oxygen, can cover 300 nautical miles and run for 16 hours before refueling. This initiative aims to clean up the shipping industry, which contributes significantly to global greenhouse gas emissions. While hydrogen production currently emits carbon dioxide, proponents foresee a shift towards cleaner methods using renewable energy sources like wind and solar power. The launch of the hydrogen-powered ferry represents a step towards achieving the International Maritime Organization's goal of halving greenhouse gas releases in commercial shipping by midcentury. Despite some environmental concerns, the project signals a positive shift towards sustainable transportation solutions and a potential future where hydrogen fuels a variety of vessels.
