Fuel cells convert hydrogen and oxygen into electricity and heat and emit only pure water. Because hydrogen fuel cells have zero noise and no moving parts they create no sound or vibration both on board and in marine ecosystems.​

Multi-Megawatt (MW) Fuel cells are currently being used to generate power in stationary applications with >1MW systems being used in port marine environments for over a decade. In maritime shipping applications, fuel cells have been used in seagoing vessels, including passenger vessels and submarines, for over 30 years. Source: Zestas
