E-mobility travels on board the yacht

Siemens, Vsy and Lloyd’s Register together in the project of a sustainable and environmentally friendly system: generation of energy on board a luxury boat or 65 meters of the Tuscan shipyard

The collaboration between Siemens and PowerCell Sweden, a Swedish manufacturer of hydrogen fuel cells for Siemens’ integrated energy and propulsion system, SISHIP BlueDrive, which aims to provide a more sustainable and efficient energy supply to boats, is about to find another field of navigation. Recently a real application of this integrated solution has been developed – the first in Italy in the luxury yacht sector – the result of the collaboration between Siemens, Vsy, manufacturer of luxury mega yachts over 60 meters, and Lloyd’s Register, one of the main international suppliers of classification and certification services for the naval industry.

The aim of the project is to create a 200kW power system on a special version of the new Vsy 65m Waterecho yacht, through the integration of hydrogen fuel cells and lithium-ion batteries to power the stern electric motor (used for maneuvers) or as an auxiliary engine) and night-time hotel services, without the use of diesel generators, resulting in a greener and more environment-friendly navigation.

Vsy’s Waterecho

Designed by Espen Øino, one of the most talented and recognized pens in the world of pleasure boating, the Vsy Waterecho seeks to achieve the balance between comfort and sustainability. A combination that is based on the search for high performance as well as the reduction of fuel consumption and greater efficiency: characteristics of the strategy of Vsy but also of Siemens, always committed to the development of environmentally friendly and advantageous solutions, from the point of view productive, for the nautical and shipbuilding sector.

The collaboration between Siemens, Vsy and Lloyd’s Register sees, on the one hand, Vsy engaged in establishing the performance targets of the onboard power generation system in relation to the entire design of the boat, and on the other side, sees Siemens provide their know-how and technological solutions; finally Lloyd’s Register carry out an “Approval in Principle” for the classification of the boat, indicating the technical requirements for the safety of the use of hydrogen fuel cells, gas storage and installation on board of innovative yachts.

The integrated energy and propulsion system, SISHIP BlueDrive from Siemens, specifically designed for the naval industry, and PowerCell’s hydrogen fuel cells, can be integrated into the on-board propulsion and power generation systems with lithium-ion batteries (like Siemens’ BlueVaultTM) or in the electric motors of boats, thus creating an efficient and sustainable supply and storage system for electricity. Thanks to the increasingly widespread use of battery-operated drive systems, especially in ferries, the goal is now to extend the concept of sustainable energy supply through hydrogen fuel cells, characterized by high efficiency and a consequent navigation with reduced fuel consumption.
