Retrofit
Holland Shipyards Group is working on the retrofit of the inland vessel 'Maas' to sail on hydrogen for its client Future Proof Shipping.
Retrofitting the internal combustion technology with hydrogen technology, removing both main engine and gearbox, and installing a new modular propulsion system. This will consist 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 will be 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 will be 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 will contain a 750V DC bus bar and an e-motor for propulsion.
Vessels' specification:
LENGTH: 110 m
WIDTH: 11,45 m
CAPACITY: 825 kW and 504 kWh
