Ampereship has completed the successful conversion of the passenger vessel Uetliberg to fully electric propulsion.

Now operating on Lake Zurich, the vessel is the largest battery-powered passenger ship in Switzerland and, with its 3.6 MWh battery system, is projected to save approximately 113,000 litres of diesel and 300 tonnes of CO₂ annually. The project demonstrates the feasibility of operating even large, existing passenger ships in a future-proof and emission-free manner, representing a decisive step towards greener operations on lakes and rivers.
