Baglietto has teamed up with Siemens Energy and CGT to develop a new hybrid propulsion system to be installed on the boatbuilder’s hybrid yachts.
The new hybrid propulsion system is a further step forward in the shipyard’s research in new environmentally friendly technologies.
After being tested, it will be installed on hybrid propulsion T52 and DOM 133 yachts from 2025.
The new system will be suitable for mounting on vessels built with the Bzero hydrogen-based technology.
The components have been supervised, verified, and certified by the Lloyd’s Register of Shipping.
“The new system will implement a hybrid-parallel propulsion architecture ensuring maximum flexibility, compact installation and on-board comfort, as well as improved mechanical and electrical efficiency,” explained Baglietto’s CEO Diego Michele Deprati. “Once more, Baglietto shows its determination to explore new, innovative paths in the implementation of alternative energy sources.
“And, in doing so, it moves one step closer to the goals already set with the Bzero system, aimed at reaching truly sustainable yachting.”
High-efficiency
The new system – a latest-generation power train – consists of a Caterpillar C32 ACERT diesel endothermic engine and an ultracompact hybrid unit which integrates a low-consumption clutch and a 180kW high-efficiency electrical machine.
The system works as an electric propulsion motor and as a shaft generator system. The whole power train is managed by Siemens Energy BlueDrive Eco propulsion control system.
This solution was developed by Siemens Energy in cooperation with Stromag and Lucchi Motori.
The system will allow yachts to cruise in diesel mode, diesel shaft generation mode (without the gensets), electric diesel mode (with the gensets only), and full electric mode.
In the traditional diesel and diesel shaft generation modes, the Caterpillar C32 ACERT main engines are compatible with diesel fuels obtained from 100% renewable energy sources such as HVO (hydro-treated vegetable oil) and synthetic diesel fuels (e-diesel) compliant to standard EN15940.
In diesel-electric mode, the combination of a conventional diesel genset plus variable-speed diesel genset will enable a yacht to cruise at speeds of up to 9 knots using bio-diesel fuels.
In full electric mode, the latest-generation Li-ion battery packs with prismatic cells will allow a yacht to cruise with zero emission.
