The vessel has undergone a complete retrofit from traditional internal combustion technology to cutting-edge hydrogen fuel technology. The project involved removing the main engine and reduction gearbox, replacing the diesel engine driving the bow thruster and diesel generators with a new modular propulsion system. This system includes electric motors, hydrogen tanks, a Proton Exchange Membrane (PEM) fuel cell system for converting hydrogen into electric power, and a battery system. The H2 Barge 2 features six fuel cell modules, providing a total fuel cell capacity of 1.2 MW.
