Start-up Aurelia Green Ship Concept Design, which focuses on zero-emission shipping, unveiled a new design for the first ro-ro that used 100% hydrogen propulsion. The company says the ship’s unique designs, which received approval in principle from RINA based on recently published rules for hydrogen ships, can also be a model for heavy-lift, ro-pax and cargo vessels. cruising to adopt pure hydrogen energy.


The new design concept is the ACD01 1000, an electrically powered ro-ro cargo ship using highly compressed H2 as fuel. The energy needed to operate the ship will come entirely from compressed hydrogen, which will not generate any harmful emissions for the environment. The design would support operation of the vessel both at sea and in port.


Hybrid propulsion is based on battery and fuel cell power modules. It is not supported by internal combustion engines using conventional fuels. The batteries are also used as an energy storage source to power the hotel load.


“The world of zero emissions is a pioneering world open to new opportunities, which reminds me to some extent of the first operations in the heavy transport sector,” said Ton Bos, partner and co-founder of Aurelia. “The cooperation with RINA is a strong signal that the maritime world is ready to work together for clean shipping.”


The company sees it as a pioneering design that can be applied to other segments of shipping. The hull is designed to ensure excellent hydrodynamics and maximum propeller efficiency while the entire vessel meets and goes well beyond the limits set by EEDI Phase 3 according to the MEPC, they noted. In addition, the ballast water treatment plant complies with the latest amendments of the International Convention on Ballast Water Management.


“This new design of a compressed hydrogen ro-ro vessel is part of a long-term cooperation between Aurelia and RINA in which we will develop a liquefied hydrogen propulsion system that could be used for heavy lift, cruise and Ro-Ro vessels. -Pax,” said Raffaele Frontera, founding partner of Aurelia Green Concept Design.


RINA noted that they are also using the experience developed in this partnership to refine its recently published rules for hydrogen. They focus on challenges as well as verifying the technological readiness and systems used for hydrogen storage, supply and bunkering.
