The world’s first passenger boat powered with fuel cells made its maiden voyage in Hamburg, Germany last Friday.

The hybrid fuel cell drive for the passenger ferry FCS Alsterwasser was produced by Proton Motor based in Puchheim, Germany.

Until now fuel cell motors of this capacity for marine applications have only been used for military uses in submarines, though Proton Motor is also exploring similar technology for use in small trucks, buses and forklifts.

Dubbed the “ZemShip” (zero emission ship), the Alsterwasser, will undergo test runs until November, when it will begin carrying up to 100 passengers on tourist cruises.
