Aurelia Green Ship Concept Design’s new 100% hydrogen powered RORO vessel design has secured the certificate of Approval in Principle from Italy’s classification society RINA. The new design concept is the ACD01 1000 featuring electric propulsion using highly compressed H2 as fuel. The vessel is intended for transporting ro-ro cargo. Beyond the green design, the difference is marked by the ship’s hydrogen-based engine system, which can be applied to other ship designs. The fuel used to operate the vessel is 100% compressed hydrogen which generates no environmentally harmful emissions with a design which can be considered as zero emission not only in port, but also during navigation, RINA said. The hybrid propulsion is based on battery and fuel cell power modules and it is not supported by internal combustion engines. The new design complies well beyond the limits settled by EEDI Phase 3. It includes a ballast water treatment plant, in accordance with the latest amendments of the International Ballast Water Management Convention, and the hull is designed to ensure hydrodynamic and propeller efficiency.
