The first hybrid passenger vessel is considered a development benchmark for all ferry shipping in Estonia. Ambitious climate targets are accelerating the transition to cleaner technologies and solutions. TS Laevad was the first company in Estonia to use a diesel-electric hybrid solution on a ferry that runs with frequent daily departures and maneuvers, including in the winter months – in sub-zero temperatures. Previously, the battery technology anywhere in the world has not been used on such a large passenger ferry operating in such ice conditions in winter.
