The MV Sea Change, a hydrogen-powered ferry, can operate for about 300 nautical miles and 16 hours before needing to refuel4. This is made possible by its hydrogen fuel cells, which generate electricity through a reaction that combines oxygen and hydrogen, resulting in water as a byproduct.

The main byproduct of the ferry's hydrogen fuel cells is water. The fuel cells produce electricity through an electrochemical reaction that combines oxygen and hydrogen, resulting in the emission of water as a byproduct. This technology helps reduce greenhouse gas emissions and contributes to a cleaner environment.
