Hydrogen-powered Water Taxi

19.5m

This unique 19.5 m water taxi design has been developed as a shuttle service between luxury hotels and resorts in the Red Sea with sustainability in mind. The propulsion system is a commercial-grade series hybrid powertrain designed for multiple redundancies for safety within a pioneering technology window. Sixty kilograms of hydrogen are carried to be converted into electric power by a hydrogen fuel cell and regulated through a Power and Automation System (PAS). The PAS output is converted to the correct motor needs through an Energy Storage System (ESS) battery to enable increased power range. The ESS balances the power flow between the motors and the PAS. The electric motors draw on the ESS power as required from the operator interface, driving three Hamilton waterjets.

A fully independent system, the ESS can be charged either through the fuel cell, or alternatively by onshore charging to reduce hydrogen consumption, as per operational requirements. Onshore electrical input for both ESS and house systems is also flexibly received, either through dual AC 440 V/150 A sockets to on-boat battery chargers, or direct from dual DC fast chargers up to 230 kW. All system elements are independently Class Approved by DNV, and the entire drivetrain system is being inspected by DNV to ensure compliance with the highest international industry standards.
