Italy-based yacht builder Baglietto Yachts has announced the introduction of a new hybrid propulsion system onboard its yachts from 2025.
Following extensive research and development, Baglietto plans to install the hybrid propulsion system on T52 and DOM 133 yachts starting in 2025. The new system will also be available for vessels built with the Bzero hydrogen-based technology, with all components supervised, verified, and certified by the Lloyd’s Register of Shipping.

The new system 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 in an extremely limited space.
The electrical machine serves a dual purpose, to operate as an electric propulsion motor, with utmost comfort and reduced noise, and as a shaft generator system to enhance efficiency and optimise consumption. Siemens Energy's BlueDrive Eco, an advanced propulsion control system, oversees the entire powertrain. 
The system allows yachts to cruise in diesel mode, diesel shaft generation mode without the gensets, diesel electric mode with the gensets only, and full electric mode. In the traditional diesel and diesel shaft generation modes, her Caterpillar engines are compatible with the use of diesel fuels obtained from 100% renewable energy sources, such as HVO and e-diesel.
The latter, coming from highly renewable energy sources, ensures a reduction of up to 90 percent of the CO2 emissions calculated over the entire life cycle of the product, from process start to its final use.
“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,” concluded Diego Michele Deprati.
