For Future Proof Shipping we have completed a retrofit of their inland vessel 'Maas' to sail on hydrogen.

We replaced the internal combustion technology with hydrogen technology, removing both main engine and gearbox, and installing a new modular propulsion system. This consists of electric motors, hydrogen tanks, a PEM fuel cell system (necessary for converting hydrogen into electricity) and a battery system. The compressed hydrogen tanks, the fuel cells and the battery system are separate units that can be removed for maintenance or replacement purposes.

The hydrogen and fuel cell system are installed in the cargo space of the vessel, with the hydrogen being placed above the fuel cell system in two 40ft containers (approximately 1000kg at 300 bar).

The fuel cell system is triple redundant with 825 kW capacity (to supply propulsion and auxiliary power) and a 504 kWh Lithium-ion battery pack for peak shaving, secondary and bridging power. The system contains a 750V DC bus bar and an e-motor for propulsion.
