EST-Floattech supplies batteries to Rolls-Royce in an order for nine battery hybrid ferries
Under an agreed framework contract, EST-Floattech will supply its ’Green Orca 1050’-series battery modules as part of Rolls-Royce’s propulsion contract to outfit nine ferries for Italian operator Liberty Lines.
Each of the modules has a 10.5 kWh capacity, with the total outfitting contract for EST-Floattech adding 3,118.5 kWh of power to the propulsion order for the vessels.
Spanish shipyard Astilleros Armon will build the identical sister ships and the ships are expected to begin operations in 2024.
The vessels will sail between the Italian island province of Sicily in the Mediterranean and Croatia in the Adriatic Sea, along with shorter crossings between different Italian islands








“The Framework Agreement is a milestone achievement for EST-Floattech. Rolls-Royce Power Systems and EST-Floattech will work well together. Both companies are setting milestones on the road to climate-neutral shipping with the approved Series 2000 and Series 4000 mtu marine diesel engines, respectively the approved and DNV-certified Green Orca 1050 batteries”,
EST-Floattech CCO, Walter van der Pennen
The Liberty Lines Hybrid Fleet
In total, Liberty Lines is set to introduce nine hybrid ferries into their fleet, significantly upgrading their services across the Mediterranean. This project aligns with global efforts to reduce the carbon footprint of the maritime sector and is a key part of Liberty Lines’ strategy to provide greener transportation options to its passengers. Each ferry will be equipped with the latest technological advancements in hybrid propulsion, ensuring efficient and eco-friendly operations across Italy’s islands and coastal regions.
Vittorio Morace
The “Vittorio Morace”, named after the late founder of Liberty Lines, is the world’s first hybrid high-speed ferry to IMO HSC standard with a length of almost 40 metres is fast at sea and emission-free in harbour.

Cristina M
The Cristina M, another vessel in Liberty Lines’ hybrid fleet, embodies the operator’s commitment to sustainability and passenger comfort. Similar in design to the Vittorio Morace

After careful selection, testing and integration of the EST-Floattech battery system into the mtu Hybrid Propulsion pack it is great to see that the battery system is performing very well.Philippe Gorse, Director Mission Critical E/E Hardware at Rolls-Royce Power Systems
